Product Description
CNMN090404 Solid CBN Cutting Insert Interrupt Cutting Bearing steel Wind Power Bearings
1. Halnn Tools Solid CBN Cutting Insert Interrupt Cutting Bearing steel Wind Power Bearings
For large slewing bearings, the hardness after heat treatment is generally above HRC45. Grinding is often used to machine slewing bearings. Although high workpiece accuracy can be obtained, the grinding efficiency is too low, which affects the machining efficiency.
With the continuous development of cutting technology, the tool industry castings have developed tool materials that can be used instead of grinding, and lathe processing instead of grinding machine processing can not only improve the processing efficiency, but also meet the drawing requirements. At present, the simple machining process used in mechanical processing plants is roughing-heat treatment-finishing, and turning is used instead of grinding.

3.Advantages of Halnn Solid CBN Cutting Insert
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).
