With the development of science and technology, the precision requirements for the processing of extra large bearings are getting higher and higher. Due to the limitation of the machining precision of the general CNC vertical lathe, the reaming reamer of the grinding process has a longer grinding time and lower efficiency. With the development and application of superhard tools (CBN tools), in many cold machining, grinding can be replaced by turning.

CBN tool features for hard-turned bearing:

(1) CBN cutters have high hardness and wear resistance and are the second highest hardness materials known at present. When processing high hardness materials, dimensional deviation and dimensional dispersion in processing of large parts can be reduced.

(2) CBN tools have high thermal stability and high temperature hardness. When the cutting temperature is high, it is beneficial to the cutting process, but has little effect on the tool life.
