1. Halnn Tools SNGN090312 Square PCBN Cutting Tool Hard Heavy Interrupt Cutting Hardened Steel Wind Power Bearings
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.

4.Application Case
Processing wind power bearing surface
The CBN tool BN-S20 grade square insert is used to process the surface of the wind power bearing to obtain a higher surface finish;
Common blade models: SNMN150716 or SNGN120712, due to the Solid polycrystalline CBN tool, need to be equipped with a professional hardened tool bar CSDNN central cutting tools protection inserts.
