High Speed Machining Hardened Steel Wind turbine bearing With DNGA150604-4S Brazed CBN Cutting Tool
1. Halnn Tools Brazed CBN Cutting Tool High Speed Machining Hardened Steel Wind turbine bearing
The hardness and wear resistance of ceramic inserts are higher than those of cemented carbide inserts. However, due to the large brittleness, large machining allowance or easy-disintegration when there is intermittent working condition in the machined part, there is a certain limit in the field of turning instead of grinding bearings. .
The Halnn Tools PCBN insert is currently a more effective material for turning bearings instead of grinding. In particular, the BN-S20, BN-S200 and BN-H11 grades are widely used in the hard turning of bearings. And for different processing conditions, choose different tool grades, BN-S200 and BN-H11 grades are used for continuous cutting conditions, BN-S20 grades are suitable for any working conditions (continuous, interrupted cutting conditions).

3. Advantages os Halnn Tools Brazed CBN Cutting Tool
Halnn Tools CBN tool hard turning bearing advantages
(1) The processing efficiency is doubled: the machining efficiency is four times higher than that of the same machining accuracy.
(2) Suitable for mass production: CBN tools have high durability, reduce tool change frequency and reduce production costs.
(3) Reducing pollution: Turned iron scraps are more convenient to handle and recycle. At the same time, CBN tools are used to hard-turn bearings without adding cutting fluid to reduce environmental pollution.
The CBN tool cooperates with the vertical lathe hard turning bearing technology, with high processing efficiency and low cost. With the introduction of CBN tools, it is possible to replace the production configuration of several vertical grinding machines with lathes and reduce the construction cost of the plant.
