[0032] See appendix Figure 1-4 As shown in the figure, a special forming milling cutter for processing bearing rings according to an embodiment of the present invention includes a tool holder 1. The front end of the tool holder 1 is cut to form a tool head 7. Multiple cutting edges 2 are cut on the side circumference of the tool head 7. The front end of the tool head 7 is cut to form a cutting edge 3 and a cutting edge 4. The cutting edge 4 and the cutting edge 3 are arranged intersectingly. The front end faces of the cutting edge 4 and the cutting edge 3 are planar structures.
[0033] The bearing ring machining special forming milling cutter of the above technical solution is mainly used to mill the bearing ring. The cutter head 7 is reinforced by cross-set cutting edge 2 4 and cutting edge 1 3, so that the overall structure of the milling cutter is stable. Multiple cutting edges 2 on the side circumference of the cutter head 7 are used to grind the inner circumference of the bearing ring, which can ensure that the inner circle is ground at the same time as the bearing ring is milled.
[0034] See Figure 2As shown in the embodiment of this utility model, multiple cutting edges 2 are arranged in a circumferential angle around the central axis of the cutter head 7. There are four cutting edges 2. The first cutting edge 3 and the second cutting edge 4 are arranged perpendicular to each other. The two ends of the first cutting edge 3 are respectively connected to the ends of two cutting edges 2 away from the shank 1, and the two ends of the second cutting edge 4 are respectively connected to the ends of the other two cutting edges 2 away from the shank 1. The multiple cutting edges 2 are arranged in a circumferential angle around the central axis of the cutter head 7 to ensure that the cutting force is evenly distributed during the machining process, thereby improving machining efficiency and workpiece surface quality. The number of cutting edges 2 is set to four, and the first cutting edge 3 and the second cutting edge 4 are arranged perpendicular to each other and connected to the cutting edges 2 respectively, which further enhances the stability and cutting performance of the milling cutter structure.
[0035] See Figure 3 As shown in the embodiment of this utility model, two grooves 5 are provided between the first cutting edge 3 and the second cutting edge 4, and the two grooves 5 are respectively located on both sides of the second cutting edge 4. The setting of the two grooves 5 helps to reduce friction and resistance during the cutting process and improve cutting efficiency.
[0036] See Figure 4 As shown in the embodiment of this utility model, each blade 2 has a W-shaped notch 6 on its outer side, which helps to remove chips and dissipate heat, and prevents overheating and chip accumulation during the cutting process.
[0037] In this embodiment of the invention, each blade 2 is arranged in a spiral, and the spiral angle of each blade 2 is 15°, so as to provide better cutting effect and longer service life.
[0038] In this embodiment of the invention, the inverted taper BT=0 of the outer diameter of the cutting edge 2 helps to ensure stability and accuracy during the cutting process and improve machining quality.
[0039] In this embodiment of the utility model, the special forming milling cutter for machining bearing rings is made entirely of 100Cr6 bearing steel. 100Cr6 bearing steel is characterized by its high carbon and high chromium content. After heat treatment, it has high hardness and good wear resistance, capable of withstanding significant cutting forces and frictional wear, thus extending the service life of the milling cutter. This material has excellent cutting performance, easily forming complex-shaped cutting edges 2 and connecting rib structures, ensuring the milling cutter maintains high precision and efficiency when machining bearing rings. 100Cr6 bearing steel has high toughness, resisting impact and vibration during cutting, reducing the risk of cutting edge 2 chipping and breakage, and improving the stability and safety of the machining process. During high-speed cutting or long-term machining, 100Cr6 bearing steel maintains good thermal stability, not easily softening or deforming due to temperature increases, ensuring machining accuracy and workpiece quality. The material's corrosion resistance maintains good performance in humid or corrosive environments, making it suitable for various machining environments. Due to its excellent cutting performance and wear resistance, it can significantly reduce tool change frequency and downtime, thereby reducing overall machining costs.
[0040] In summary, the forming milling cutter for machining bearing rings according to this utility model embodiment has the following technical effects:
[0041] 1. Stable structure: The cross-shaped cutting edges 3 and 4 enhance the overall structural stability of the milling cutter, making it suitable for milling and turning bearing rings while simultaneously performing grinding.
[0042] 2. Uniform cutting force: Multiple cutting edges 2 are arranged in a circumferential angle around the central axis of the cutting head 7 to ensure uniform distribution of cutting force during processing, thereby improving processing efficiency and workpiece surface quality.
[0043] 3. Chip removal and heat dissipation: The W-shaped notch 6 design helps with chip removal and heat dissipation, preventing overheating and chip accumulation during the cutting process.
[0044] 4. Excellent cutting effect: Each cutting edge 2 is spirally arranged with a spiral angle of 15°. This design provides better cutting effect and longer service life.
[0045] 5. High machining accuracy: The inverted taper BT=0 on the outer diameter of the cutting edge 2 helps to ensure stability and accuracy during the cutting process and improve machining quality.
[0046] 6. Excellent material properties: The entire structure is made of 100Cr6 bearing steel, which has high hardness, high wear resistance, high toughness, good thermal stability and corrosion resistance. It can significantly reduce the frequency of tool replacement and downtime, and reduce the overall processing cost.
