Finishing 42CrMo hardened steel Gear With halnn Tools CBN Cutting Tools more high efficiency
1. Halnn Tools CBN Cutting Tools Finishing 42CrMo hardened steel Gear
With the development of the society, more and more manufacturers choose pcbn insert hard turning hardened steel. Why they choose cbn insert for hard turning ? What is the advantages of cbn insert hard turning hardened steel?
1.Good Characteristics of cbn insert itself: Halnn non-metal adhesive cbn insert, not only has high hardness, good abrasive resistance and heat resistance, but also has strong impact resistance. It can be used for large allowance and interrupt turning hardened steel with high efficiency.
2.Costs low comparing with grinding process: Grinding process need different grinding machine, However with Halnn cbn insert hard turning hardened steel, it doesn’t need special cutting tools, machines and holders, we can choose common lathe and cnc lathe.
