Introduction to the processing of stainless steel parts, stainless steel, hard, will generate a lot of heat during processing, which will greatly damage the tool. It often causes headaches for many people. With the right medicine, everything becomes easier.
Tungsten-cobalt alloys have good toughness, light cutting, and chips are not easy to stick to the tool, especially suitable for roughing and interrupted cutting stainless steel turning with large vibration. Our commonly used cutter heads are W10, W20, YW2. The material of the shank is 45-gauge steel quenched and tempered, which can strengthen the strength and rigidity.
The stainless steel parts processing company said that the rake angle of the tool is 15°~20°, which is the most suitable for the treatment of stainless steel cutting heat. When roughing, use a smaller relief angle first; when finishing, because it is easy to harden the material during processing, the relief angle of about 6°~8° is the most suitable. In general, the relief angle should be appropriately larger than when machining ordinary carbon steel. The inclination angle of the blade is usually 15°. In the case of fine turning of outer circles, fine turning holes, and fine planing planes, when the amount of cutting tool is relatively small, a tool with a large blade inclination angle of about 50° should be used.
According to the stainless steel parts processing company, the cutting speed should not be too fast. The line speed is 60~80 m/s, and the cutting amount is 5-6 mm each time. A few wires to half a millimeter mm/r is appropriate. Never treat stainless steel in the same way as ordinary carbon steel
The cooling lubricant can reduce the cutting heat and cutting force during the cutting process, which not only prolongs the service life of the tool, but also ensures the smoothness of the product. Emulsion can be used, but for products with high requirements on smoothness, special cutting oil for stainless steel should be used
