Description

Technical Field

[0001] This invention relates to the field of combined cutting tool technology, and in particular to a sawing and milling combined cutting tool. Background Technology

[0002] A saw blade end mill is a composite tool that combines the functions of a saw blade and an end mill, typically made of materials such as W6Mo5Cr4V2 high-speed steel or cemented carbide. Existing saw blade end mills have several drawbacks in application. Current technology usually employs single-cutter machining, which has several significant disadvantages. First, directly ordering the diamond cutter head results in a longer length, leading to low utilization of the diamond disc and a significant increase in cutter head cost. Second, the large cutter head size limits the number of teeth in the design, resulting in a rough cutting surface and affecting machining quality. Furthermore, as the cutter head size increases, the welding process becomes more difficult and time-consuming, thus affecting the tool's lifespan. Single-cutter machining also has the limitation of not being able to adjust the profile, failing to meet the machining requirements of different workpieces. For small spindles (≤25.4mm), the stability of clamping a single end mill during machining is poor, further limiting machining accuracy and efficiency. These problems significantly limit the practical application of existing technology, particularly in terms of cost control, machining quality, and equipment compatibility.

[0003] For example, the "Novel Disc-Type Saw and Milling Combination Tool" disclosed in Chinese patent literature, application number "CN200920127337.3", includes a circular saw blade and a circular milling cutter. The cutting edge of the circular milling cutter is fixedly mounted 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 novel disc-type saw and milling combination tool of the present invention uses a combination of a circular saw blade and a circular milling cutter. While sawing, the circular milling cutter mills the saw cut surface of the material, resulting in a small surface roughness of the material. This reduces equipment investment, lowers production costs, reduces processing steps, and improves production efficiency.

[0004] Although the above solution can mill the cut surface of the material with a circular milling cutter while sawing, it still has the problems of not being able to adjust the profile and poor stability during the processing. Summary of the Invention

[0005] To address the problem that the profile of a single cutter head cannot be adjusted in existing technologies, this invention provides a combined cutting tool. Through the innovative combination design of saw blade and milling cutter and high-frequency welding process, the stability and machining accuracy of the tool are significantly improved, resulting in a high-efficiency and low-cost diamond tool machining solution.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A combined cutting 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 head that fits into the end face of the saw blade. By embedding the milling head of the milling cutter into the saw blade, more precise milling can be achieved. Furthermore, due to the embedded design, stability and accuracy during processing are ensured, avoiding errors that may arise from using the saw blade and milling cutter separately in traditional methods. Existing technologies have limitations, such as the large cutter head leading to a rough cutting surface and high cost when machining with a single cutter. However, the combined design of this solution reduces the area of ​​a single cutter head, thereby lowering the cost. Moreover, the smaller cutter head allows for the design of more teeth, improving the precision of the cutting surface. Compared to common solutions, the saw-milling combined cutting tool of this invention has significant advantages. First, structurally, common saw blades and milling cutters are usually used separately, while this invention combines them, reducing the number of tool changes and time, and improving processing efficiency. Second, the embedded fit between the milling head and the saw blade improves processing accuracy and avoids the accumulation of errors caused by traditional processing methods. In addition, this design also solves the problems of high cost of the cutting head and rough cutting surface caused by the large cutting head in the existing technology.

[0008] Preferably, a sleeve is also included, through which the saw blade and the milling cutter are connected to the machine spindle. The sleeve acts as an intermediary, allowing for more precise tool installation and positioning. The fit between the center hole and the machine spindle ensures the coaxiality of the tool during machining, thereby reducing machining errors caused by improper installation. Furthermore, this design simplifies the tool change process and improves production efficiency. Due to existing issues with tool installation stability, especially on small spindles, the stability of clamping a single milling cutter is poor in traditional single-cut milling processes, which can affect machining quality and efficiency. Introducing a sleeve can significantly improve tool installation stability, particularly in applications on small spindles. Common solutions may employ direct clamping or screw fixing, which can lead to loosening or instability during high-speed rotation or heavy-duty cutting. The sleeve design of this invention, through the tight fit between the center hole and the spindle, improves the stability and reliability of the connection. This not only improves the connection stability between the tool and the spindle but also simplifies the installation process and increases production efficiency. This design can also be adjusted according to different machine spindle sizes, exhibiting excellent versatility and adaptability. Furthermore, the sleeve design facilitates quick tool changes and maintenance. It's worth noting that the sleeve design can be further optimized for automatic alignment and locking mechanisms with the tool, enabling a higher level of automation and intelligent manufacturing.

[0009] Preferably, the saw blade is equipped with noise-reducing lines, which are hook-shaped and hollow in the middle; these lines are evenly distributed along the axis of the central hole on the saw blade. This design not only enhances the functionality of the tool but also improves operational comfort and safety during use. The main function of the noise-reducing lines is to reduce the noise generated by the saw blade during high-speed rotation and to improve heat dissipation efficiency through the hollow design, thus preventing the tool from overheating due to prolonged operation. The hook-shaped design helps to capture and remove debris generated during cutting, reducing damage to the tool and workpiece, and also helps to improve the surface finish of the cut. This solution can solve the problem of rough cut surfaces caused by large tool heads when directly machining with a single tool in the prior art. By adding noise-reducing lines, noise can be reduced and heat dissipation improved while maintaining the cutting efficiency of the tool, thereby improving machining quality. Traditional tools may not consider noise and heat dissipation issues or use simple straight bar designs, which may not be effective in reducing noise or improving heat dissipation efficiency. The noise reduction line design of this invention, through its hook-shaped and hollow characteristics, achieves better noise reduction and heat dissipation effects, and enhances the ability to remove debris, which helps to improve the smoothness of the cut surface.

[0010] Preferably, the saw blade has evenly distributed sawing heads, which are joined to the saw blade body via high-frequency welding. This welding technology not only ensures a strong bond between the sawing heads and the saw blade body but also guarantees the structural stability and durability of the tool during use. High-frequency welding is a highly efficient joining method that can achieve a tight connection between metals in a short time, while reducing the heat-affected zone and maintaining the original properties of the material. During the saw blade manufacturing process, joining the diamond sawing heads to the saw blade body via high-frequency welding ensures the stability of the heads during high-speed rotation and cutting, preventing head detachment or damage due to weak connections. Traditional tools may use screws or adhesives to join the heads to 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 joining technology, provides a more reliable and durable bond, extending the tool's lifespan. Furthermore, the use of high-frequency welding reduces material waste and production costs caused by improper connections.

[0011] Furthermore, the sawing heads are evenly distributed in numbers of 60-100. This even distribution ensures more uniform contact between the saw blade and the workpiece during cutting, thereby improving cutting efficiency and quality. Additionally, the even distribution helps reduce localized wear and extends the saw blade's lifespan. High-frequency welding ensures a strong connection between each head and the saw blade body, maintaining the overall stability and reliability of the tool. This design is based on the need to improve cutting efficiency and surface quality. In existing technologies, the large size of individual heads results in a rough cut surface, and the number of teeth is limited. By increasing the number of sawing heads, cutting efficiency can be maintained or improved while refining the cutting texture, significantly improving the smoothness and precision of the cut surface. Compared to existing technologies, increasing the number of heads provides finer cutting, reduces vibration and noise during cutting, increases cutting speed, and reduces processing time, thereby improving production efficiency. Simultaneously, the evenly distributed heads help disperse cutting forces, reduce heat accumulation, and extend tool life. Furthermore, by further studying the arrangement and spacing of the cutting heads, the cutting effect can be further optimized and the service life of the cutting tools can be improved.

[0012] Preferably, the milling cutter has milling heads distributed on it, and the milling heads are bonded to the milling cutter via high-frequency welding. The distribution design of the milling heads allows the milling cutter to achieve high-precision and high-efficiency milling operations during machining. The application of high-frequency welding technology ensures the bonding strength between the milling heads and the milling cutter body, maintaining stability even under high load or high-speed rotation conditions. In existing technologies, machining a single tool suffers from roughness and high cost of the cutting head. By using high-frequency welding technology to combine the milling heads with the milling cutter body, the durability and efficiency of the tool can be significantly improved, while reducing the risk of tool failure due to poor welding, providing a more stable and durable connection method. Furthermore, the distribution design of the milling heads is also part of the innovation; the refined design of the arrangement and spacing of the milling heads can further improve cutting efficiency and surface finish.

[0013] Preferably, the saw blade has placement holes, and the milling cutters correspond to these holes, with 8-20 milling cutters evenly distributed. The placement holes allow for precise alignment and engagement of the milling cutters with the saw blade, ensuring the stability and accuracy of the milling cutters during machining. By providing a specific number of placement holes on the saw blade, a uniformly distributed space can be provided for the milling cutters, achieving more precise and uniform milling operations. In the prior art, the number of teeth on the cutters is relatively small, resulting in a rough cutting surface. By providing placement holes on the saw blade and aligning the milling cutters with these holes, the number of cutters can be increased, thereby improving the quality and precision of the cutting surface. Furthermore, this design helps to solve the problem of low machining efficiency caused by unreasonable cutter design. Compared with common cutter designs, this invention provides a more precise cutter layout by providing placement holes on the saw blade and aligning the milling cutters with them. This method can effectively improve the accuracy of milling machining while reducing machining errors caused by uneven cutter distribution. The placement holes also help simplify the assembly and maintenance process of the cutters.

[0014] Furthermore, the milling cutter head is equipped with a cutter head platform of width H, which fits into the mounting hole, with H set to 0.5-1.0 mm. By setting the width H of the cutter head platform to 0.5-1.0 mm and fitting it into the mounting hole on the saw blade, this tight fit not only ensures the stability of the milling cutter head during operation but also significantly improves machining accuracy by reducing cutter head displacement or vibration. In addition, the precise cutter head platform width setting of 0.5-1.0 mm provides flexibility for milling cutter heads of different diameters or lengths, adapting to diverse machining needs. By fully considering the stability and durability of the tool during use, reducing cutter head wear extends the tool's service life, reduces maintenance costs, and improves production efficiency.

[0015] Furthermore, a first shim 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 machining needs. The use of the first shim allows users to optimize force distribution and heat generation during the cutting process by changing the thickness or shape of the first shim according to specific machining conditions and material properties, thereby improving machining accuracy and surface quality. In addition, this adjustment method simplifies tool management, reduces inventory costs, and facilitates maintenance. The introduction of the first shim not only improves the versatility of the saw-milling combination tool but also provides a simple and effective means to optimize machining results.

[0016] Furthermore, the saw blade and the milling cutter respectively abut against the sleeve and the second washer on both sides; both the second washer and the sleeve are provided with chamfers and grooves. The introduction of chamfers provides a smoother transition for tool installation and removal, reducing potential damage to the machine or tool during operation. This design not only improves the operator's experience but also helps protect the integrity of the machine and tools, extending their service life. Simultaneously, the grooves provide additional fixing and connection points for the second washer and the sleeve, 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 crucial for ensuring machining quality, especially during fine machining, ensuring precise tool control and repeatability. By further optimizing the shape, size, and position of these features, it is possible to better adapt to the requirements of different materials and machining conditions. This design flexibility allows for personalized customization of the tool, enabling it to meet the needs of specific application scenarios.

[0017] Furthermore, the mating surfaces of the second washer and the sleeve are provided with interlocking textures or patterns to increase the coefficient of friction with the saw blade and the milling cutter, ensuring stability during high-speed rotation.

[0018] Therefore, the present invention has the following beneficial effects:

[0019] By setting a precisely sized cutter head platform, a tight fit with the placement hole is achieved, significantly improving the accuracy of milling, reducing machining errors caused by cutter head displacement or vibration, and ensuring the quality and consistency of the workpiece.

[0020] The groove design of the second gasket and sleeve enhances the fixation between the tool assemblies, improves stability during high-speed rotation or cutting, effectively extends the tool's service life, and reduces production interruptions caused by tool damage.

[0021] The chamfered design on the equipment reduces damage to the machine or tools during installation or disassembly, optimizes the operator's experience, and improves safety during operation, reducing the risk of accidents.

[0022] The integrated design of the saw blade and milling cutter simplifies the tool change process, improves work efficiency, and effectively increases production efficiency and reduces production costs by reducing tool change time.

[0023] The second gasket and sleeve, manufactured using special materials and processes, enhance the durability and stability of the cutting tool, improve its adaptability to different materials and environments, extend the tool's maintenance cycle, and reduce long-term operating costs.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0031] Example 1

[0032] like Figure 1 As shown, in this embodiment, a combined cutting 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 head 8 that fits into the end face of the saw blade B. The milling head 8 includes a machining surface, and the machining surface changes its working area according to the distance between the saw blade B and the milling cutter C. It also includes a sleeve D, through which the saw blade B and the milling cutter C are connected to the machine spindle via a central hole 12.

[0033] like Figure 4 As shown, by embedding the milling head 8 of the milling cutter C onto the saw blade B, more precise milling can be achieved. Furthermore, the embedded design ensures stability and accuracy during machining, avoiding errors that may arise from using the saw blade and milling cutter separately in the traditional method. The sleeve D acts as an intermediary, making the installation and positioning of the tool more precise. The fit between the sleeve's center hole 15 and the machine spindle ensures the coaxiality of the tool during machining, thereby reducing machining errors caused by improper installation.

[0034] In traditional techniques, machining with a single cutter results in a rough cutting surface due to the large cutter head, as well as high cutter head costs. However, the combined design of this solution reduces the area of ​​a single cutter head, thereby lowering costs. Furthermore, the smaller cutter head allows for the design of more teeth, improving the precision of the cutting surface. Compared to common solutions, the saw-milling combination tool of this invention has significant advantages. First, structurally, common saw blades and milling cutters are usually used separately, while this invention combines them, reducing the frequency and time spent changing tools and improving processing efficiency. Second, the embedded fit between the milling cutter head 8 and the saw blade B improves machining accuracy and avoids the accumulation of errors caused by traditional machining methods. In addition, this design solves the problems of high cutter head costs and rough cutting surfaces caused by large cutter heads in existing technologies.

[0035] Furthermore, the sleeve design simplifies the tool change process and improves production efficiency. Due to existing technology's tool installation stability issues, the stability of clamping a single end mill is poor in traditional single-end mill machining, especially with small spindles ≤25.4mm, which can affect machining quality and efficiency. Introducing the sleeve D significantly improves tool installation stability, particularly in applications with small spindles. Common solutions may employ direct clamping or screw fixing, which can lead to loosening or instability during high-speed rotation or heavy-duty cutting. The sleeve design of this invention, through a tight fit between the center hole and the spindle, improves the stability and reliability of the connection. This not only improves the connection stability between the tool and the spindle but also simplifies the installation process, increasing production efficiency. This design can also be adjusted according to different machine spindle sizes, offering excellent versatility and adaptability. In addition, the sleeve D design facilitates quick tool change and maintenance. It is worth noting that the sleeve design can further consider an automatic alignment and locking mechanism with the tool to achieve a higher level of automation and intelligent production.

[0036] like Figure 2As shown, in this embodiment, the saw blade B includes a saw blade head 1, a saw blade body 2, a noise-reducing line 3, a central hole 4, a placement hole 5, a first positioning hole 6, and a second positioning hole 7. The noise-reducing line 3 is hook-shaped and hollow in the middle; the noise-reducing line 3 is evenly distributed on the saw blade B along the axis of the central hole 4. This design not only improves the functionality of the tool but also enhances the comfort and safety of operation during use. The main function of the noise-reducing line 3 is to reduce the noise generated by the saw blade during high-speed rotation and to improve heat dissipation efficiency through the hollow design, thereby preventing the tool from overheating due to prolonged operation. The hook-shaped design helps to capture and remove debris generated during the cutting process, reducing damage to the tool and workpiece from debris, and also helps to improve the surface finish of the cut. This solution can solve the problem of rough cut surfaces caused by a large cutter head when directly machining with a single blade in the prior art. By adding the noise-reducing line design, noise can be reduced and heat dissipation improved while maintaining the cutting efficiency of the tool, thus improving the machining quality. Traditional cutting tools may not consider noise and heat dissipation issues, or they may employ a simple straight-line design, which may not effectively reduce noise or improve heat dissipation efficiency. The silencing line design of this invention, through its hook-shaped and hollowed-out characteristics, achieves better noise reduction and heat dissipation, and also enhances chip removal capabilities, contributing to a smoother cut surface.

[0037] The saw blade B has evenly distributed saw cutting heads 1, which are joined to the saw blade body 2 by high-frequency welding. There are 60-100 saw cutting heads 1 evenly distributed throughout the blade.

[0038] The use of this welding technology not only ensures a strong bond between the saw head and the saw blade body, but also guarantees the structural stability and durability of the tool during use. High-frequency welding is a highly efficient connection method that can achieve a tight connection between metals in a short time, while reducing the heat-affected zone and maintaining the original properties of the material. During the manufacturing process of saw blade B, high-frequency welding is used to combine the diamond saw head 1 with the saw blade body 2, ensuring the stability of the head during high-speed rotation and cutting, and preventing the head from falling off or being damaged due to a weak connection. Traditional tools may use screws or adhesives 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, provides a more reliable and durable bond, extending the tool's lifespan. Furthermore, the use of high-frequency welding can reduce material waste and production costs caused by improper connections. The uniform distribution of the saw head 1 ensures more uniform contact between the saw blade B and the workpiece during cutting, thereby improving cutting efficiency and quality. Furthermore, the uniform distribution of the cutting heads helps reduce localized wear and extend the saw blade's lifespan. The use of high-frequency welding ensures a strong connection between each cutting head and the saw blade body 2, thus maintaining the overall stability and reliability of the tool. This design is based on the need to improve cutting efficiency and surface quality. In existing technologies, the large size of individual cutting heads results in a rough cutting surface, and the design of the number of cutting teeth is limited. By increasing the number of sawing heads, cutting efficiency can be maintained or improved while refining the cutting texture, thereby significantly improving the smoothness and precision of the cutting surface. Compared to existing technologies, increasing the number of cutting heads provides finer cutting, reduces vibration and noise during the cutting process, increases cutting speed, and reduces processing time, thereby improving production efficiency. Simultaneously, the uniformly distributed cutting heads help disperse cutting forces, reduce heat accumulation, and extend tool life. Furthermore, by further studying the arrangement and spacing of the cutting heads, the cutting effect can be further optimized and the tool life improved.

[0039] like Figure 3 As shown, the milling cutter C has milling heads 8 distributed on it, and the milling heads 8 are joined to the milling cutter C by high-frequency welding. The saw blade B has placement holes 5, and the milling heads correspond to the placement holes 5. There are 8-20 milling heads 8 evenly distributed on the milling cutter C of this invention. The milling cutter C of this invention has milling heads 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.

[0040] The distribution design of the milling cutter head 8 allows the milling cutter C to achieve high-precision and high-efficiency milling operations during machining. The application of high-frequency welding technology ensures the bonding strength between the milling cutter head and the milling cutter body, maintaining stability even under high load or high-speed rotation conditions. In existing technologies, machining a single tool results in roughness and high cost of the cutter head. By using high-frequency welding technology to combine the milling cutter head with the milling cutter body, the durability and efficiency of the tool can be significantly improved, while reducing the risk of tool failure due to 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, namely, the refined design of the arrangement and spacing of the milling cutter heads, which can further improve cutting efficiency and surface finish. The placement hole 5 allows for precise alignment and engagement of the milling cutter head 8 with the saw blade B, ensuring the stability and accuracy of the milling cutter head during machining. 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 existing technologies, the number of teeth on the cutter is relatively small, resulting in a rough cutting surface. By setting placement holes 5 on the saw blade and aligning the milling cutter heads 8 with these holes, the number of cutter heads can be increased, thereby improving the quality and precision of the cut surface. Furthermore, this design helps solve the problem of low machining efficiency caused by unreasonable tool design. Compared with common tool designs, this invention provides a more precise tool layout by setting placement holes 5 on the saw blade and aligning the milling cutter heads with them. This method can effectively improve the accuracy of milling operations while reducing machining errors caused by uneven cutter head distribution. The placement holes also help simplify the tool assembly and maintenance process.

[0041] Furthermore, the milling cutter head 8 is equipped with a cutter head platform of width H, which fits into the placement hole 5, with H set to 0.5-1.0 mm. By setting the width H of the cutter head platform to 0.5-1.0 mm and fitting it into the placement hole 5 on the saw blade B, this tight fit not only ensures the stability of the milling cutter head 8 during operation but also significantly improves machining accuracy by reducing cutter head displacement or vibration. In addition, the precise cutter head platform width of 0.8 mm provides flexibility for milling cutters of different diameters or lengths, adapting to diverse machining needs. By fully considering the stability and durability of the tool during use, reducing cutter head wear extends the tool's service life, reduces maintenance costs, and improves production efficiency.

[0042] In this embodiment, a first shim E1 is provided between the saw blade B and the milling cutter C to adjust the profile. Both the first shim E1 and the sleeve F are provided with a chamfer 13 and a groove 14. This design significantly improves the adaptability and flexibility of the tool, enabling it to meet different machining needs. The use of the shim allows users to optimize the force distribution and heat generation during the cutting process by changing the thickness or shape of the shim according to specific machining conditions and material properties, thereby improving machining accuracy and surface quality. Furthermore, this adjustment method simplifies tool management, reduces inventory costs, and facilitates maintenance. The introduction of the shim not only improves the versatility of the saw-milling combination tool but also provides a simple and effective means to optimize machining results. The chamfer 13 provides a smoother transition for tool installation and removal, reducing potential damage to the machine or tool during operation. This design not only improves the operator's user experience but also helps protect the integrity of the machine and tool, extending their service life. Simultaneously, 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 processes. 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 crucial for ensuring machining quality, especially in fine machining, ensuring precise tool control and repeatability. Further optimization of the shape, size, and position of these features allows for better adaptation to the requirements of different materials and machining conditions. This design flexibility enables personalized tool customization to meet the needs of specific applications.

[0043] In particular, in this embodiment, the mating surfaces of the gasket and the sleeve are provided with interlocking textures or patterns to increase the coefficient of friction with the saw blade and the milling cutter, thereby ensuring stability during high-speed rotation.

[0044] The core of this invention lies in the ingenious combination of saw blade B and milling cutter C. With the assistance of sleeve D and second washer E2, efficient and stable operation of the cutting tool is achieved. Saw blade B has evenly distributed sawing heads 1, which are bonded to the saw blade B via high-frequency welding, improving the quality of the cut surface. The number of sawing heads 1 is set between 60 and 100, which not only increases the contact points on the cutting surface and reduces wear at individual points, but also improves the overall cutting efficiency. Simultaneously, the saw blade B is also designed with noise-reducing lines 3, hook-shaped and hollow in the middle, evenly distributed along the axis of the saw blade, providing excellent noise reduction and heat dissipation, extending the service life of the saw blade.

[0045] The design of the milling cutter C is equally crucial. Its diamond cutting heads 8 are combined with the saw blade body 9 through high-frequency welding. The number of evenly distributed cutting heads 8 is between 8 and 20, ensuring high efficiency and high precision in the milling process. In particular, the design of the cutting head platform of the cutting head 8, with a width H set at 0.8mm, cleverly solves the problem of inaccurate profile caused by welding and grinding when using multiple blades in combination.

[0046] Furthermore, the saw blade B and the milling cutter C are precisely fitted through the mounting hole 5, allowing the protruding part of the milling cutter to accurately embed into the mounting 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 shim E1. The design of the second shim E2 and the sleeve D takes into account the ease of installation; the chamfer 13 and the groove 14 simplify the installation process and ensure the quick and accurate assembly of the tool assembly.

[0047] The sleeve D and the second washer E2 effectively solve the problem of poor machining stability for 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 during the machining process by reducing vibration, thereby improving product consistency and reliability.

[0048] The tool assembly of this invention achieves efficient material cutting through the coordinated operation of a saw blade B and a milling cutter C. Both the saw blade tip and the milling cutter tip are 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 ensures accurate control of machining depth and shape. The use of a first shim E1 further enhances the tool's adjustability, allowing it to adapt to different machining requirements. The stable connection of the sleeve D ensures the stability of the entire tool assembly during high-speed rotation, preventing machining instability caused by an excessively small spindle.

[0049] The usage scheme of the combined cutting tool disclosed in this application is as follows:

[0050] First, during the preparation phase, the operator must ensure the cleanliness and precision of the equipment spindle to avoid affecting the installation and operation of the cutting tools due to spindle instability or impurities. Next, assemble the components in the following order: sleeve, milling cutter, saw blade, and shim. This step requires the operator to possess certain technical knowledge and familiarity with the structure of the invention to ensure that each component is correctly installed.

[0051] The installation of sleeve D is the starting point of the entire process. Its design increases the contact area with the spindle, addressing the issue of poor machining stability with small spindles. The operator must ensure that sleeve D is correctly installed on the spindle, achieving quick and stable fixation through chamfer 13 and groove 14. Subsequently, the installation of the end mill C requires precise alignment with the center hole of sleeve D. This step is crucial because the diamond tip 8 of the end mill C directly affects the machining results. The placement hole 5 of the end mill C must precisely mate with the corresponding part of the saw blade B to ensure the stability and machining accuracy of the end mill C. The first positioning hole 11 and the second positioning hole 12 of the end mill are located at the same positions as the first positioning hole 6 and the second positioning hole 7 of the saw blade, respectively. The position of the saw blade tip is determined by the sum of the total profile length F and the saw blade protrusion G, which is typically set to 15-25mm.

[0052] The installation of saw blade B follows immediately. The diamond cutting heads 1 on saw blade B are bonded to the saw blade body 2 via high-frequency welding, providing a distribution of 60-100 diamond cutting heads. This not only improves the quality of the cut surface but also enhances the durability of the saw blade. The design of the noise reduction line 3 also needs attention during the installation of saw blade B to ensure that it performs its functions of noise reduction and heat dissipation during operation.

[0053] The first shim E1 provides the possibility of adjustment between the saw blade and the milling cutter, solving the problem that the profile cannot be adjusted by a single tool. The material and thickness of the first shim E1 can be selected according to specific machining requirements to achieve the best machining results.

[0054] Throughout the installation process, the operator must pay attention to the cleanliness and alignment of all components, as even minor errors can lead to a decrease in machining quality or damage to the cutting tools. Furthermore, excessive force should be avoided during installation to prevent damage to the cutting tools or equipment.

[0055] In application, the technical solution of this invention has high value and feasibility. By reducing the area of ​​a single cutter head, this invention not only reduces the cost of the cutter head but also reduces the processing difficulty and improves processing efficiency. The combined use of the saw blade B and the milling cutter C, along with the assistance of the second shim E2 and the sleeve D, enables this invention to adapt to diverse processing needs, especially in applications requiring high precision and stability.

[0056] In this embodiment, high-frequency welding technology is used to combine the diamond cutting head with the saw blade and the milling cutter body, improving the durability and stability of the tools. Secondly, the optimization of the number of diamond cutting heads in the saw blade B and the milling cutter C, as well as the design of the placement hole 5 and the first shim E1, solve the problems of profile adjustment and roughness in traditional single-tool machining. Finally, the design of the sleeve D and the second shim E2 provides an innovative solution to the problem of insufficient stability of the small spindle.

[0057] Example 2

[0058] In this embodiment, the versatility of the combined cutting tool can be improved by further optimizing the distribution density of the diamond cutting head or changing the geometry of the saw blade and milling cutter to adapt to different material properties and processing requirements. Furthermore, the material selection and surface treatment of the gasket and sleeve can also be adjusted according to different working environments to achieve better wear resistance and corrosion resistance.
