How to process stainless steel?

1. Tool material selection Due to the high cutting force and high cutting temperature when machining stainless steel parts, cubic hydrogenation turning blades with hardness second only to diamond and capable of withstanding high temperatures can be used. In addition, its chemical inertness is very large, and it does not play a chemical role with iron group metals at 1200~1300℃, so it is very suitable for processing stainless steel materials. 2. Tool geometry parameters. Tool geometry parameters play an important role in its cutting performance. In order to make cutting brisk and smooth, cemented carbide tools should adopt a larger rake angle to improve tool life. This is conducive to strengthening the blade and giving full play to the superiority of the higher compressive strength of the ceramic tool. The size of the relief angle directly affects the wear of the tool, and also has an impact on the strength of the blade. The change of the entering angle will affect the change of the radial and axial cutting components, as well as the size of the cutting width and cutting thickness. 3. The roughness value of the rake face should be small during sharpening. In order to avoid the phenomenon of chip sticking, the front and flank faces of the tool should be sharpened carefully to ensure that the roughness value is small, thereby reducing the resistance of chip outflow and avoiding chips. Sticky knife. 4. The cutting edge of the tool should be kept sharp. The cutting edge of the tool should be kept sharp to reduce work hardening. The feed rate and back-cutting amount should not be too small to prevent the tool from cutting in the hardened layer and affect the service life of the tool. 5. Pay attention to the grinding of the chip breaker. Because stainless steel chips have the characteristics of toughness, the chip breaker on the rake face of the tool should be properly ground, so that the cutting process can interrupt the chip, hold the chip, and facilitate chip removal. 6. The selection of cutting oil should be appropriate. Because stainless steel has the characteristics of easy adhesion and poor heat dissipation, it is very important to choose cutting oils with good anti-adhesive and heat dissipation properties during cutting. Yida Borun special stainless steel cutting oil for lubrication. 7. Selection of cutting amount According to the characteristics of stainless steel material, low speed and larger feed rate should be selected for cutting. Using the above process method can overcome the difficulties of stainless steel processing, greatly improve the tool life of stainless steel during cutting, reduce the number of times of sharpening and changing tools in operation, and improve the production efficiency and cutting accuracy, reduce the labor intensity and labor intensity of the workers. In terms of comprehensive production costs, satisfactory results can be achieved.
