[0002] The three-edge ball end mill is a special milling tool with a unique structure and a wide range of applications.

[0003] A three-edge ball-end milling cutter is a milling cutter with a spherical cutter head connected to a shank, usually made of cemented carbide material, with high hardness, high wear resistance and excellent cutting performance;

[0004] Its spherical head design allows for smoother milling cuts, reduces cutting force and burrs on the workpiece surface, and improves processing quality. At the same time, the three-edge design can improve cutting efficiency and stability, and reduce vibration and noise compared to single-edge or double-edge milling cutters;

[0005] In the process of processing three-edge ball end mills, a ball end mill grinder is required for processing. However, the existing ball end mill grinder lacks the processing work for the three-edge ball end mills when in use, and the floating dust on the surface of the three-edge ball end mills is easy to affect the grinding accuracy. At the same time, there is a lack of protective components, which makes it easy for the sparks generated by the three-edge ball end mills when grinding with the grinding wheel to spatter, which is easy to spatter onto the workers and cause burns to the workers. Subsequently, the adjustment of the grinding mechanism lacks lighting auxiliary devices, which makes it easy for the grinding mechanism to be affected by light during adjustment, resulting in adjustment deviations. Summary of the invention

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Embodiment 1

[0037] See also Figure 1-9The present invention provides the following technical solutions: a novel grinding process for a three-edge ball end milling cutter, comprising a base 1 and a grinding mechanism installed at the top of the base 1, an electric cabinet 2 and a grinding wheel 3 connected to the motor output shaft on both sides of the electric cabinet 2 are installed at the top of the base 1, a first protective shell 4 and a second protective shell 5 are installed at the top of the base 1, a tool setting seat 19 is installed at the front end of the electric cabinet 2, a placement box 10 is installed at the front end of the base 1, a fixture seat 17 is placed inside the placement box 10, an air pump 20 is installed on the outer wall of the base 1, an air pipe 21 is installed at the connecting end of the air pump 20, a nozzle 24 is installed at the end of the air pipe 21, an air valve 23 is installed on the surface of the air pipe 21, and a support plate 22 is installed at the top of the nozzle 24;

[0038] The grinding process is as follows: S1. Take the fixture seat 17 out of the placement box 10, then use the fixture seat 17 to fix the three-edge ball head milling cutter, and then use the tool seat 19 to align the cutter; S2. When the tool alignment is completed, the three-edge ball head milling cutter and the fixture seat 17 are placed on the top of the support plate 22, and the air pump 20 is used to work. The air flow through the air pipe 21 is ejected from the nozzle 24, and then the gas passes through the opening at the top of the support plate 22 to blow away the floating dust on the surface of the three-edge ball head milling cutter and the fixture seat 17; S3. After the three-edge ball head milling cutter and the fixture seat 17 are cleaned, the fixture seat 17 is fixed on the grinding mechanism, and the three-edge ball head milling cutter is also fixed through the fixture seat 17, and then the electric cabinet 2 starts the grinding wheel 3 to rotate and grind the three-edge ball head milling cutter.

[0039] In the preferred embodiment: the grinding mechanism includes: a first fixed seat 6, a first adjusting rod 7, a second fixed seat 8 and a second adjusting rod 9, the first adjusting rod 7 is assembled inside the first fixed seat 6, the second adjusting rod 9 is assembled inside the second fixed seat 8, and the first fixed seat 6 and the second fixed seat 8 are installed on both sides of the top of the base 1 correspondingly.

[0040] In the embodiment, the grinding process needs to obtain the processing parameters of a three-edge ball end milling cutter, and these parameters include:

[0041] Cutting edge shape accuracy: This is a key factor in ensuring the quality of the machined surface. High-precision products can significantly improve the smoothness of the machined surface.

[0042] Cutting parameters: including cutting speed, feed rate and cutting depth. Rough machining requires high production efficiency, while fine machining requires guaranteed machining accuracy and surface quality, while taking into account tool life.

[0043] Tool material and geometric parameters: The choice of tool material directly affects its wear resistance and cutting performance, while geometric parameters such as tool angle and edge shape have an important influence on the cutting process and processing quality.

[0044] Grinding process parameters: such as grinding speed, grinding feed, selection of grinding wheel 3, etc. These parameters need to be optimized according to the tool material and geometry to ensure grinding efficiency and grinding quality.

[0045] At the same time, after grinding, it is also necessary to inspect the appearance of the three-edge ball end milling cutter and measure whether the three-edge ball end milling cutter meets the standards after grinding.

[0046] First, the air pump 20 is started, and the high-pressure airflow generated by the air pump 20 is delivered to the nozzle 24 at a specific position through the connected air pipe 21. The nozzle 24 is carefully designed and installed at an appropriate height and angle to ensure that the airflow can be sprayed out efficiently and concentratedly.

[0047] When the airflow is strongly ejected from the nozzle 24, it is directed directly to and passes through the opening at the top of the support plate 22. The support plate 22 acts as a stable support structure, and the opening at the top allows the airflow to pass smoothly without being hindered.

[0048] The airflow passing through the support plate 22 has sufficient power to quickly and effectively blow away the floating dust, tiny particles and other impurities on the surface of the three-edge ball end milling cutter and the fixture seat 17. This process is very important for improving machining accuracy, protecting the tool and the surface from damage by impurities, and maintaining the cleanliness of the working environment.

[0049] Embodiment 2

[0050] See also Figure 1-9 A telescopic plate 11 is installed at the top of the base 1, and a sliding groove 12 is opened at the top of the base 1. The telescopic plate 11 is unfolded and slidably connected to the inside of the sliding groove 12, and the unfolded length of the telescopic plate 11 is the same as the length of the sliding groove 12.

[0051] In the embodiment, when the telescopic plate 11 is activated and opened, it will automatically unfold along the preset sliding groove 12, quickly and accurately covering the front end of the base 1. This automatic unfolding process is intended to instantly build a solid safety barrier during the processing operation. The core function of this barrier is to prevent sparks, debris and other dangerous objects generated by the high-speed rotating grinding wheel 3 during the grinding process from splashing, thereby directly and effectively protecting the operator from burns and other potential injuries, ensuring the overall safety of the working environment.

[0053] See also Figure 1-9A control button 13 is installed at the top of the electric cabinet 2. There are three control buttons 13. One of the control buttons 13 is electrically connected to the motor, and the other two control buttons 13 are electrically connected to explosion-proof lamps 14. The explosion-proof lamps 14 are installed at the top of the first protective shell 4 and the second protective shell 5. The outer cover of the explosion-proof lamp 14 is provided with a transparent lampshade 15. The surface of the transparent lampshade 15 protruding from the mounting ear is connected with bolts 16.

[0054] In the preferred embodiment, the transparent lampshade 15 is fixedly connected to the first protective shell 4 and the second protective shell 5 by bolts 16 .

[0055] In the embodiment, by operating the control button 13, the motor can be started with one click to drive its output shaft to rotate, thereby driving the grinding wheel 3 to perform efficient grinding operations, which is specially used for fine grinding of three-edged ball-end milling cutters. In addition, the control button 13 also has the function of turning on the explosion-proof lighting lamp 14, which is specially designed for the grinding environment and provides bright and stable light to ensure a clear field of vision in the operating area. Its main purpose is to assist the operator to more accurately identify the position and angle of the tool, facilitate fine adjustments, and thus directly improve the accuracy and overall efficiency of the processing process. At the same time, the transparent lampshade 15 is equipped as a protective barrier to effectively isolate the sparks generated during the grinding process, protect the explosion-proof lighting lamp 14 from damage, and ensure the continuous and stable operation of the lighting system.

[0058] In the embodiment, the introduction of the fan 18 provides an effective heat dissipation solution for the heat generated by the grinding wheel 3 during the processing. Its main purpose is to prevent the grinding wheel 3 from being degraded or damaged due to excessive temperature, ensure the stability and service life of the grinding wheel 3, and also help to improve the continuity and efficiency of the processing process.

[0060] See also Figure 1-9 A placement plate 25 is inserted into one side of the front end of the base 1, a threaded rod 26 is connected to the bottom end of the placement plate 25, and a support foot 27 is threadedly connected to the bottom end of the threaded rod 26.

[0061] In the preferred embodiment, the lifting height of the supporting foot 27 through the threaded rod 26 is the same as that of the base 1 .

[0062] In the preferred embodiment: a first magnetic block 28 is installed at the top of the placement plate 25 , and a second magnetic block 29 is installed at the front end of the base 1 .

[0063] In the preferred embodiment, the placement plate 25 is magnetically fixedly connected to the base 1 through the first magnetic block 28 and the second magnetic block 29 .

[0064] In the embodiment, firstly, the threaded connection design between the threaded rod 26 and the support foot 27 realizes the flexible lifting and lowering adjustment of the support foot 27, ensuring that it can be firmly in contact with the ground to form a stable fulcrum. This feature not only facilitates the placement of the equipment, but also enhances the stability of the overall structure.

[0065] Next, the design of pulling out the placement plate 25 effectively expands the placement area of ​​the tool, providing a dedicated and spacious storage space for the three-edge ball end mill. This design aims to solve the inconvenience of manually holding the tool and the problem of tool damage or loss caused by random placement, ensuring the neat, orderly and safe storage of the tool.

[0066] Finally, the magnetic connection between the second magnetic block 29 and the first magnetic block 28 ensures that the placement plate 25 can be firmly fixed inside the base 1 when it is not in use, which saves space and avoids the potential safety hazards caused by the movement of the placement plate 25. This design further improves the overall safety and convenience of the equipment, making the storage and management of knives more efficient and orderly.
