Description

Technical Field

[0001] The invention relates to the technical field of combined tool technology, in particular to a sawing and milling combined tool. Background Art

[0002] A saw blade milling cutter is a composite tool that has both saw blade and milling cutter functions, usually made of materials such as W6Mo5Cr4V2 high-speed steel or cemented carbide. The saw blade milling cutter in the prior art has some shortcomings in the application process. The prior art usually uses a single cutter for processing, which has several significant disadvantages. First, the length of the diamond cutter head directly ordered is long, resulting in low utilization of the diamond disc and a significant increase in the cost of the cutter head. Secondly, due to the large size of the cutter head, the number of teeth of the cutter is limited, resulting in a rough cutting surface, affecting the processing quality. In addition, as the size of the cutter head increases, the difficulty of the welding process also increases, and the welding time is prolonged, thereby affecting the service life of the cutter. The single cutter processing method also has the limitation of being unable to adjust the profile and cannot meet the processing requirements of different workpieces. For small spindles (≤25.4mm), the stability of clamping a single milling cutter for processing is poor, which further limits the processing accuracy and efficiency. These problems make the prior art have great limitations in practical applications, especially in terms of cost control, processing quality and equipment compatibility.

[0003] For example, the "new type of disc sawing and milling combination tool" disclosed in Chinese patent documents, with application number "CN200920127337.3", includes a circular saw blade and a circular milling cutter. The blade of the circular milling cutter is fixed on the circular saw blade coaxially with the circular saw blade, and the milling diameter is smaller than the outer diameter of the circular saw blade. The new type of disc sawing and milling combination tool of the present invention adopts a circular saw blade and a circular milling cutter combination. The sawn surface of the material is milled by the circular milling cutter while sawing, so that the roughness of the material section is small, which not only reduces equipment investment and production costs, but also reduces processing procedures and improves production efficiency.

[0004] Although the above solution can perform milling processing on the sawn surface of the material by means of a circular milling cutter while sawing, there are still problems such as the inability to adjust the profile and poor stability during the processing. Summary of the invention

[0005] In view of the problem in the prior art that a single cutter head cannot adjust the profile, the present invention provides a combined tool, which achieves significant improvements in tool stability and processing accuracy through an innovative combination design of a saw blade and a milling cutter and a high-frequency welding process, thereby obtaining a high-efficiency, low-cost diamond tool processing solution.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A combined tool is disclosed, comprising a saw blade and a milling cutter that fit together, wherein the edge of the milling cutter is provided with a milling cutter head that fits in the end face of the saw blade. By fitting the milling cutter head of the milling cutter on the saw blade, more precise milling processing can be achieved, and due to the embedded design, the stability and accuracy during the processing can be ensured, thereby avoiding the errors that may be caused by the traditional separate use of the saw blade and the milling cutter. There are limitations in the prior art, such as the large cutter head causing a rough cutting surface when a single cutter is directly processed, and the high cost of the cutter head. However, through the combined design of the present solution, the area of ​​a single cutter head can be reduced, thereby reducing the cost of the cutter head, and because the cutter head is small, it is easy to design more teeth to improve the fineness of the cutting surface. Compared with the common solutions, the saw-milling combined tool of the present invention has obvious advantages. First, in terms of structure, the common saw blade and milling cutter are usually used separately, while the present invention combines the two together, reducing the number and time of tool replacement and improving processing efficiency. Secondly, due to the embedded cooperation of the milling cutter head and the saw blade, the processing accuracy is improved, and the error accumulation caused by the traditional processing method is avoided. In addition, this design also solves the problems of high cutter head cost and rough cutting surface caused by large cutter head in the prior art.

[0007] As a preferred embodiment, a sleeve is also included, and the saw blade and the milling cutter are connected to the machine spindle through the center hole of the sleeve. The sleeve acts as an intermediary to make the installation and positioning of the tool more accurate. The cooperation between the center hole and the machine spindle ensures the coaxiality of the tool during the processing, thereby reducing the processing error caused by improper installation. In addition, this design also simplifies the tool replacement process and improves production efficiency. Due to the problem of tool installation stability in the prior art. In the traditional single milling cutter processing process, especially for small spindles, the stability of clamping a single milling cutter is not good, which may affect the processing quality and efficiency. By introducing a sleeve, the installation stability of the tool can be significantly improved, especially for applications on small spindles. Common solutions may adopt direct clamping or screw fixing, which may become loose or unstable during high-speed rotation or heavy-load cutting. The sleeve design of the present invention improves the stability and reliability of the connection through the close cooperation between the center hole and the spindle. Not only does it improve the connection stability between the tool and the spindle, but it also simplifies the installation process and improves production efficiency. This design can also be adjusted according to different machine spindle sizes, and has good versatility and adaptability. In addition, the design of the sleeve also facilitates the rapid replacement and maintenance of the tool. It is worth noting that the design of the sleeve can further consider the automatic alignment and locking mechanism with the tool to achieve a higher level of automation and intelligent production.

[0008] Preferably, the saw blade is provided with a silencer line, which is hook-shaped and hollowed out in the middle; the silencer line is evenly distributed on the saw blade along the axis of the center hole of the saw blade. This design not only improves the functionality of the tool, but also improves the comfort and safety of operation during use. The main function of the silencer line is to reduce the noise generated when the saw blade rotates at high speed, and to improve the heat dissipation efficiency through the hollow design to avoid overheating of the tool due to long-term work. The hook-shaped design helps to capture and discharge the debris generated during the cutting process, reduce the damage of the debris to the tool and the workpiece, and also helps to improve the finish of the cutting surface. This solution can solve the problem of rough cutting surface caused by large tool head when directly processing a single tool in the prior art. By adding the design of the silencer line, noise can be reduced and heat dissipation can be improved while maintaining the cutting efficiency of the tool, thereby improving the processing quality. Traditional tools may not consider noise and heat dissipation issues, or adopt a simple straight bar design, which may not effectively reduce noise or improve heat dissipation efficiency. The silencer line design of the present invention achieves better silencer and heat dissipation effects through its hook-shaped and hollow characteristics, and enhances the debris discharge capability, which helps to improve the smoothness of the cutting surface.

[0009] Preferably, the saw blade is evenly distributed with sawing heads, and the sawing heads are combined with the saw blade body by high-frequency welding. The use of this welding technology not only ensures the firm connection between the sawing heads and the saw blade body, but also ensures the structural stability and durability of the tool during use. High-frequency welding is an efficient connection method that can achieve a close connection between metals in a short time, while reducing the heat-affected area and maintaining the original performance of the material. In the manufacturing process of the saw blade, the diamond sawing head is combined with the saw blade body by high-frequency welding, which can ensure the stability of the head during high-speed rotation and cutting, and avoid the head from falling off or being damaged due to a loose connection. Traditional tools may use screws or bonding to combine the head with the saw blade body. These methods may not provide sufficient stability during high-intensity cutting and are prone to failure under high load or high-speed rotation conditions. High-frequency welding, as a mature connection technology, can provide a more reliable and lasting combination and extend the service life of the tool. In addition, the use of high-frequency welding can also reduce material waste and production costs caused by improper connection.

[0010] Furthermore, the sawing heads are evenly distributed in 60-100 pieces. The even distribution of the sawing heads can ensure that the contact between the saw blade and the processed material is more even during the cutting process, thereby improving the cutting efficiency and quality. In addition, the even distribution of the heads helps to reduce local wear and extend the service life of the saw blade. The use of high-frequency welding ensures a firm connection between each head and the saw blade body, thereby maintaining the stability and reliability of the overall tool. This design is based on the need to improve cutting efficiency and surface quality. In the prior art, due to the large size of a single head, the cutting surface is rough, and the number of tool teeth is limited. By increasing the number of sawing heads, the cutting lines can be refined while maintaining or improving the cutting efficiency, thereby significantly improving the smoothness and precision of the cutting surface. Compared with the prior art, increasing the number of heads can provide more delicate cutting, reduce vibration and noise during the cutting process, increase cutting speed, reduce processing time, and thus improve production efficiency. At the same time, evenly distributed heads help to disperse cutting forces, reduce heat accumulation, and extend the service life of the tool. In addition, by further studying the arrangement and spacing of the cutter heads, the cutting effect can be further optimized and the service life of the cutter can be increased.

[0011] Preferably, the milling cutter is provided with milling heads, and the milling heads are connected to the milling cutter by high-frequency welding. The distribution design of the milling heads allows the milling cutter to achieve high-precision and high-efficiency milling operations during the machining process. The application of high-frequency welding technology ensures the bonding strength between the milling heads and the milling cutter body, which can remain stable even under high load or high-speed rotation conditions. In the prior art, there are problems of rough machining and high cost of the heads in the machining of a single tool. By combining the milling heads with the milling cutter body using high-frequency welding technology, the durability and efficiency of the tool can be significantly improved, while reducing the risk of tool failure caused by poor welding, providing a more stable and durable connection method. Furthermore, the distribution design of the milling heads is also part of the innovation, that is, the refined design of the arrangement and spacing of the milling heads can further improve the cutting efficiency and surface finish.

[0012] Preferably, the saw blade is provided with placement holes, the milling cutter head corresponds to the placement holes, and the milling cutter head is evenly distributed in 8-20 holes. The placement holes allow the milling cutter head to be accurately aligned and fitted with the saw blade, ensuring the stability and accuracy of the milling cutter head during processing. By setting a specific number of placement holes on the saw blade, evenly distributed space can be provided for the milling cutter head, thereby achieving a more refined and uniform milling operation. In the prior art, the number of teeth of the tool is small, resulting in a rough cutting surface. By setting placement holes on the saw blade and making the milling cutter head correspond to these holes, the number of cutter heads can be increased, thereby improving the quality and accuracy of the cutting surface. In addition, this design also helps to solve the problem of low processing efficiency caused by unreasonable tool design. Compared with the common tool design scheme, the present invention provides a more accurate tool layout method by setting placement holes on the saw blade and making the milling cutter head correspond thereto. This method can effectively improve the accuracy of milling processing, while reducing the processing error caused by uneven distribution of the cutter head. The setting of the placement holes also helps to simplify the assembly and maintenance process of the tool.

[0013] Furthermore, the milling cutter head is provided with a cutter head platform with a width of H, and the cutter head platform is embedded in the placement hole, and H is set to 0.5-1.0mm. By setting the width H of the cutter head platform to 0.5-1.0mm and making it embedded in the placement hole on the saw blade, this close fit not only ensures the stability of the milling cutter head during operation, but also significantly improves the processing accuracy by reducing the displacement or vibration of the cutter head. In addition, the precise cutter head platform width is set to 0.5-1.0mm, which provides flexibility for milling cutter heads of different diameters or lengths and adapts to diverse processing needs. After fully considering the stability and durability of the tool during use, the tool life is extended by reducing the wear of the cutter head, reducing maintenance costs and improving production efficiency.

[0014] Furthermore, a first gasket is provided between the saw blade and the milling cutter to adjust the profile. This design significantly improves the adaptability and flexibility of the tool, enabling it to meet different processing requirements. The use of the first gasket allows the user to optimize the force distribution and heat generation during the cutting process by changing the thickness or shape of the first gasket according to specific processing conditions and material properties, thereby improving processing accuracy and surface quality. In addition, this adjustment method simplifies tool management, reduces inventory costs, and facilitates maintenance. The introduction of the first gasket not only improves the versatility of the saw-milling combination tool, but also provides a simple and effective means for optimizing processing results.

[0015] Furthermore, the saw blade and the milling cutter are respectively abutted against the sleeve and the second gasket on both sides; the second gasket and the sleeve are both provided with chamfers and grooves. The introduction of chamfers provides a smoother transition for the installation and removal of the tool, reducing the damage that may be caused to the machine or tool during operation. Such a design not only improves the operator's experience, but also helps to protect the integrity of the machine and the tool and extend their service life. At the same time, the setting of the groove provides additional fixing and connection points for the second gasket and the sleeve, which is particularly important during high-speed rotation or cutting. This design enhances the stability of the tool assembly, reduces the processing error caused by vibration or unstable operation, and improves the processing accuracy. The improvement of stability is crucial to ensuring the processing quality, especially when performing fine processing, it can ensure the precise control and repeatability of the tool. By further optimizing the shape, size and position of these features, it can better adapt to the requirements of different materials and processing conditions. This design flexibility provides the possibility for personalized customization of the tool to meet the needs of specific application scenarios.

[0016] Furthermore, the engaging surfaces of the second gasket and the sleeve are provided with interlocking textures or patterns to increase the friction coefficient with the saw blade and the milling cutter and ensure stability during high-speed rotation.

[0017] Therefore, the present invention has the following beneficial effects: By setting the tool head platform with precise width, a close fit with the placement hole is achieved, which significantly improves the accuracy of milling processing, reduces processing errors caused by tool head displacement or vibration, and ensures the quality and consistency of the workpiece.

[0018] The groove design of the second gasket and the sleeve enhances the fixation between the tool components, improves the stability during high-speed rotation or cutting, effectively extends the service life of the tool, and reduces production interruptions caused by tool damage.

[0019] The chamfer design on the equipment reduces damage to the machine or tool during installation or removal, optimizes the operator's experience, improves safety during operation, and reduces accidental risks.

[0020] The integrated design of saw blade and milling cutter simplifies the tool replacement process and improves work efficiency. By reducing tool replacement time, it effectively improves production efficiency and reduces production costs.

[0021] The second gasket and sleeve made of special materials and processes enhance the durability and stability of the tool, improve its adaptability to different materials and environments, extend the maintenance cycle of the tool, and reduce long-term operating costs.

DETAILED DESCRIPTION

[0027] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions.

[0028] Example 1 like Figure 1 As shown, in this embodiment, a combined tool includes a saw blade B and a milling cutter C that fit together. The edge of the milling cutter C is provided with a milling cutter head 8 that fits in the end face of the saw blade B. The milling cutter head 8 includes a processing surface, and the processing surface changes the working area accordingly according to the distance between the saw blade B and the milling cutter C. A sleeve D is also included, and the saw blade B and the milling cutter C are connected to the machine spindle through the center hole 12 of the sleeve D.

[0029] like Figure 4 As shown, by embedding the milling cutter head 8 of the milling cutter C on the saw blade B, more precise milling processing can be achieved, and because of the embedded design, the stability and accuracy during the processing can be ensured, avoiding the errors that may be caused by the traditional separate use of the saw blade and the milling cutter. The sleeve D acts as an intermediary to make the installation and positioning of the tool more accurate. The cooperation between the center hole 15 of the sleeve and the machine spindle ensures the coaxiality of the tool during the processing, thereby reducing the processing error caused by improper installation.

[0030] In the traditional technology, when a single cutter is directly processed, the large cutter head leads to a rough cutting surface and high cutter head cost. However, through the combined design of the present solution, the area of ​​a single cutter head can be reduced, thereby reducing the cost of the cutter head, and because the cutter head is small, it is easy to design more teeth to improve the fineness of the cutting surface. Compared with the common scheme, the saw-milling combination tool of the present invention has obvious advantages. First of all, in terms of structure, common saw blades and milling cutters are usually used separately, while the present invention combines the two together, reducing the number and time of tool replacement and improving processing efficiency. Secondly, due to the embedded fit of the milling cutter head 8 and the saw blade B, the processing accuracy is improved, and the error accumulation caused by the traditional processing method is avoided. In addition, this design also solves the problems of high cutter head cost and rough cutting surface caused by the large cutter head in the prior art.

[0031] In addition, the setting of the sleeve also simplifies the tool replacement process and improves production efficiency. Due to the tool installation stability problem existing in the prior art. In the traditional single milling cutter processing process, especially for small spindles ≤25.4mm, the stability of clamping a single milling cutter is poor, which may affect the processing quality and efficiency. By introducing the sleeve D, the installation stability of the tool can be significantly improved, especially for applications on small spindles. Common solutions may adopt direct clamping or screw fixing, which may become loose or unstable during high-speed rotation or heavy-load cutting. The sleeve design of the present invention improves the stability and reliability of the connection through the close fit between the center hole and the spindle. It not only improves the connection stability between the tool and the spindle, but also simplifies the installation process and improves production efficiency. This design can also be adjusted according to different machine spindle sizes, and has good versatility and adaptability. In addition, the design of the sleeve D also facilitates the rapid replacement and maintenance of the tool. It is worth noting that the design of the sleeve can further consider the automatic alignment and locking mechanism with the tool to achieve a higher level of automation and intelligent production.

[0032] like Figure 2As shown, in this embodiment, the saw blade B includes a saw blade head 1, a saw blade body 2, a silencer line 3, a center hole 4, a placement hole 5, a first positioning hole 6 of the saw blade, and a second positioning hole 7 of the saw blade. The silencer line 3 is hook-shaped and hollowed out in the middle; the silencer line 3 is evenly distributed on the saw blade B along the axis of the center hole 4 of the saw blade. This design not only improves the functionality of the tool, but also improves the comfort and safety of operation during use. The main function of the silencer line 3 is to reduce the noise generated when the saw blade rotates at high speed, and to improve the heat dissipation efficiency through the hollow design to avoid overheating of the tool due to long-term work. The hook-shaped design helps to capture and discharge the debris generated during the cutting process, reduce the damage of the debris to the tool and the workpiece, and also helps to improve the finish of the cutting surface. This solution can solve the problem of rough cutting surface caused by the large cutter head when directly processing a single knife in the prior art. By adding the design of the silencer line, the noise can be reduced and the heat dissipation can be improved while maintaining the cutting efficiency of the tool, thereby improving the processing quality. Conventional cutting tools may not consider noise and heat dissipation issues, or may adopt simple straight bar designs, which may not effectively reduce noise or improve heat dissipation efficiency. The muffler line design of the present invention, through its hook-shaped and hollow characteristics, achieves better muffler and heat dissipation effects, and enhances the ability to discharge debris, which helps to improve the smoothness of the cutting surface.

[0033] The saw blade B is evenly distributed with sawing bits 1, and the sawing bits 1 are connected to the saw blade body 2 by high-frequency welding. The sawing bits 1 are evenly distributed in 60-100 pieces.

[0034] The use of this welding technology not only ensures a firm connection between the sawing head and the saw blade body, but also ensures the structural stability and durability of the tool during use. High-frequency welding is an efficient connection method that can achieve a close connection between metals in a short time, while reducing the heat-affected area and maintaining the original performance of the material. In the manufacturing process of the saw blade B, the diamond sawing head 1 is combined with the saw blade body 2 by high-frequency welding, which can ensure the stability of the head during high-speed rotation and cutting, and avoid the head from falling off or being damaged due to loose connection. Traditional tools may use screws or bonding to combine the head with the saw blade body. These methods may not provide sufficient stability during high-intensity cutting and are prone to failure under high load or high-speed rotation conditions. High-frequency welding, as a mature connection technology, can provide a more reliable and lasting connection and extend the service life of the tool. In addition, the use of high-frequency welding can also reduce material waste and production costs caused by improper connection. The uniform distribution of the sawing head 1 can ensure that the contact between the saw blade B and the processed material is more uniform during the cutting process, thereby improving cutting efficiency and quality. In addition, the uniform distribution of the cutter heads helps to reduce local wear and extend the service life of the saw blade. The use of high-frequency welding ensures that each cutter head is firmly connected to the saw blade body 2, thereby maintaining the stability and reliability of the overall tool. This design is based on the need to improve cutting efficiency and surface quality. In the prior art, due to the large size of a single cutter head, the cutting surface is rough, and the number of cutter teeth is limited. By increasing the number of sawing cutter heads, the cutting lines can be refined while maintaining or improving the cutting efficiency, thereby significantly improving the smoothness and precision of the cutting surface. Compared with the prior art, increasing the number of cutter heads can provide more detailed cutting, reduce vibration and noise during the cutting process, increase cutting speed, reduce processing time, and thus improve production efficiency. At the same time, evenly distributed cutter heads help to disperse cutting forces, reduce heat accumulation, and extend the service life of the tool. In addition, by further studying the arrangement and spacing of the cutter heads, the cutting effect can be further optimized and the service life of the tool can be improved.

[0035] like Figure 3 As shown, the milling cutter C is provided with a milling cutter head 8, and the milling cutter head 8 is combined with the milling cutter C by high-frequency welding. The saw blade B is provided with a placement hole 5, and the milling cutter head corresponds to the placement hole 5, and the milling cutter head 8 is evenly distributed in 8-20. The milling cutter C of the present invention is provided with a milling cutter head 8, a milling cutter body 9, a milling cutter center hole 10, a first milling cutter positioning hole 11, and a second milling cutter positioning hole 12.

[0036] The distribution design of the milling cutter head 8 allows the milling cutter C to achieve high-precision and high-efficiency milling operations during the processing process. The application of high-frequency welding technology ensures the bonding strength between the milling cutter head and the milling cutter body, which can remain stable even under high load or high-speed rotation conditions. In the prior art, the processing of a single tool has the problems of rough processing and high cost of the cutter head. By combining the milling cutter head with the milling cutter body using high-frequency welding technology, the durability and efficiency of the tool can be significantly improved, while reducing the risk of tool failure caused by poor welding, providing a more stable and durable connection method. Furthermore, the distribution design of the milling cutter head 8 is also part of the innovation, that is, the arrangement and spacing of the milling cutter head are refined, which can further improve the cutting efficiency and surface finish. The placement hole 5 allows the milling cutter head 8 to be accurately aligned and engaged with the saw blade B, ensuring the stability and accuracy of the milling cutter head during the processing. By setting a specific number of placement holes on the saw blade, a uniformly distributed space can be provided for the milling cutter head, achieving a more refined and uniform milling operation. In the prior art, the number of teeth of the tool is small, resulting in a rough cutting surface. By providing placement holes 5 on the saw blade and making the milling cutter heads 8 correspond to these holes, the number of cutter heads can be increased, thereby improving the quality and accuracy of the cutting surface. In addition, this design also helps to solve the problem of low processing efficiency caused by unreasonable tool design. Compared with common tool design schemes, the present invention provides a more accurate tool layout method by providing placement holes 5 on the saw blade and making the milling cutter heads correspond to them. This method can effectively improve the accuracy of milling processing, while reducing the processing error caused by uneven distribution of cutter heads. The setting of placement holes also helps to simplify the assembly and maintenance process of the tool.

[0037] In addition, the milling cutter head 8 is provided with a cutter head platform with a width of H, and the cutter head platform is embedded in the placement hole 5, and H is set to 0.5-1.0mm. By setting the width H of the cutter head platform to 0.5-1.0mm and making it embedded in the placement hole 5 on the saw blade B, this close fit not only ensures the stability of the milling cutter head 8 during operation, but also significantly improves the processing accuracy by reducing the displacement or vibration of the cutter head. In addition, the precise cutter head platform width is set to 0.8mm, which provides flexibility for milling cutter heads of different diameters or lengths and adapts to diverse processing needs. After fully considering the stability and durability of the tool during use, the tool life is extended by reducing the wear of the cutter head, reducing maintenance costs and improving production efficiency.

[0038] In this embodiment, a first shim E1 is provided between the saw blade B and the milling cutter C to adjust the profile. The first shim E1 and the sleeve F are both provided with chamfers 13 and grooves 14. This design significantly improves the adaptability and flexibility of the tool, enabling it to meet different processing requirements. The use of shims allows the user to optimize the force distribution and heat generation during the cutting process by changing the thickness or shape of the shim according to specific processing conditions and material properties, thereby improving the processing accuracy and surface quality. In addition, this adjustment method simplifies tool management, reduces inventory costs, and facilitates maintenance. The introduction of shims not only improves the versatility of the saw-milling combined tool, but also provides a simple and effective means for optimizing the processing effect. The introduction of chamfers 13 provides a smoother transition for the installation and removal of the tool, reducing the damage that may be caused to the machine or tool during operation. Such a design not only improves the operator's experience, but also helps to protect the integrity of the machine and tool and extend their service life. At the same time, the setting of the groove 14 provides additional fixing and connection points for the second shim E2 and the sleeve F, which is particularly important during high-speed rotation or cutting. This design enhances the stability of the tool assembly, reduces machining errors caused by vibration or unstable operation, and improves machining accuracy. Improved stability is essential to ensure machining quality, especially when performing fine machining, to ensure precise control and repeatability of the tool. By further optimizing the shape, size and position of these features, it can better adapt to the requirements of different materials and processing conditions. This design flexibility makes it possible to customize the tool to meet the needs of specific application scenarios.

[0039] In particular, in this embodiment, the joint surfaces of the gasket and the sleeve are provided with meshing textures or patterns to increase the friction coefficient with the saw blade and the milling cutter and ensure stability during high-speed rotation.

[0040] The core of the present invention lies in the ingenious combination of saw blade B and milling cutter C. With the assistance of sleeve D and second gasket E2, efficient and stable operation of the tool is achieved. Saw blade B is evenly distributed with sawing heads 1, which are combined with saw blade B through high-frequency welding to improve the quality of the cutting surface. The number of sawing heads 1 is set between 60 and 100, which not only increases the contact points of the cutting surface and reduces the wear of a single point, but also improves the overall cutting efficiency. At the same time, a silencer line 3 is also designed on saw blade B, which is hook-shaped and hollowed in the middle, and is evenly distributed along the axis of the saw blade, which plays a good role in silencer and heat dissipation, and prolongs the service life of the saw blade.

[0041] The design of the milling cutter C is also critical. The diamond cutter head 8 on it is combined with the saw blade body 9 through high-frequency welding. The number of evenly distributed cutter heads 8 is 8-20, ensuring high efficiency and high precision in the milling process. In particular, the cutter head platform design of the cutter head 8, with a width H set at 0.8mm, cleverly solves the problem of inaccurate profiles caused by welding and grinding during the use of multiple pieces.

[0042] In addition, the saw blade B and the milling cutter C are precisely matched through the placement hole 5, and the protruding part of the milling cutter can be accurately embedded in the placement hole of the saw blade. This design not only improves the stability of the tool assembly, but also provides the possibility of adjusting the profile through the use of the first gasket E1. The design of the second gasket E2 and the sleeve D takes into account the convenience of installation. The setting of the chamfer 13 and the groove 14 simplifies the installation process and ensures the fast and accurate assembly of the tool assembly.

[0043] Sleeve D and second gasket E2 effectively solve the problem of poor machining stability of small spindles (≤25.4mm) by increasing the contact area with the spindle. This design not only improves the machining accuracy of the tool, but also reduces errors in the machining process by reducing vibration, improving product consistency and reliability.

[0044] The tool combination of the present invention realizes efficient cutting of materials through the coordinated work of the saw blade B and the milling cutter C. The saw blade head and the milling cutter head are both made of diamond. The high-speed rotation of the saw blade generates continuous cutting force, while the precise positioning and protruding design of the milling cutter ensure the precise control of the processing depth and shape. The use of the first gasket E1 further improves the adjustment flexibility of the tool, so that the tool can adapt to different processing requirements. The stable connection of the sleeve D ensures the stability of the entire tool combination when rotating at high speed, and prevents the problem of unstable processing caused by a spindle that is too small.

[0045] The use scheme of the combined tool disclosed in this application is as follows: First, in the preparation stage, the operator needs to ensure the cleanliness and accuracy of the equipment spindle to avoid the instability or impurities of the spindle affecting the installation and operation of the tool. Then, the sleeve, milling cutter, saw blade, and gasket are assembled in this order. This step requires the operator to have certain technical knowledge and familiarity with the structure of the present invention to ensure that each component is correctly installed in place.

[0046] The installation of sleeve D is the starting point of the entire process. It is designed to increase the contact area with the spindle and solve the problem of poor machining stability of small spindles. The operator needs to ensure that sleeve D is correctly installed on the spindle and quickly and stably fixed through chamfers 13 and grooves 14. Subsequently, the installation of milling cutter C needs to be precisely aligned with the center hole of sleeve D. This step is crucial because the diamond head 8 of milling cutter C will directly affect the machining effect. The placement hole 5 of milling cutter C needs to be precisely matched with the corresponding part of saw blade B to ensure the stability and machining accuracy of milling cutter C. The first positioning hole 11 and the second positioning hole 12 of the milling cutter are respectively located at the same position as the first positioning hole 6 and the second positioning hole 7 of the saw blade. The so-called saw blade tip position is determined by the sum of the total length F of the profile and the protrusion G of the saw blade. The protrusion G of the saw blade is usually set to 15-25mm.

[0047] The installation of saw blade B follows closely. The diamond segments 1 on saw blade B are combined with the saw blade body 2 by high-frequency welding, providing a distribution of 60-100 diamond segments, which not only improves the quality of the cutting surface, but also enhances the durability of the saw blade. The design of the silencer line 3 also needs to be paid attention to when installing saw blade B to ensure that it can play the role of silencer and heat dissipation during operation.

[0048] The first shim E1 provides the possibility of adjustment between the saw blade and the milling cutter, solving the problem that a single cutter cannot adjust the profile. The material and thickness of the first shim E1 can be selected according to specific processing requirements to achieve the best processing effect.

[0049] During the entire installation process, the operator needs to pay attention to the cleanliness and alignment of each component. Any slight error may lead to a decrease in processing results or damage to the tool. In addition, excessive force should be avoided during installation to avoid damage to the tool or equipment.

[0050] When applied, the technical solution of the present invention has high value and feasibility. By reducing the area of ​​a single cutter head, the present invention not only reduces the cost of the cutter head, but also reduces the difficulty of processing and improves the processing efficiency. The combined use of the saw blade B and the milling cutter C, as well as the assistance of the second gasket E2 and the sleeve D, enables the present invention to adapt to changing processing requirements, especially in situations requiring high precision and stability.

[0051] In this embodiment, the diamond bit is combined with the saw blade and the milling cutter body by high-frequency welding technology, which improves the durability and stability of the tool. Secondly, the optimization of the number of diamond bits of the saw blade B and the milling cutter C, as well as the design of the placement hole 5 and the first gasket E1, solve the problems of profile adjustment and rough processing in traditional single-piece tool processing. Finally, the design of the sleeve D and the second gasket E2 provides an innovative solution to the problem of insufficient stability of the small spindle.

[0052] Example 2 In this embodiment, the distribution density of the diamond bit can be further optimized or the geometric shapes of the saw blade and the milling cutter can be changed to adapt to different material properties and processing requirements, thereby improving the versatility of the combined tool. In addition, the material selection and surface treatment of the gasket and the sleeve can also be adjusted according to different working environments to achieve better wear resistance and corrosion resistance.
