Bearings, as one of the most important components to support the rotation of machinery and equipment s, it needs to work in bad environment, and requires high on the Anti-fatigue strength and wear resistance. And it also proposes higher requirements on the corresponding cbn cutting tools.
The size precision and surface roughness of the bearings can be finished with finishing process, so it requires high on the cutting tools in the finishing process. And Halnn CBN Insert will be the right choice for fine finishing bearings, which not only can meet the roughness requirements of Ra0.8~0.4, but also can improve the efficiency and reduce the production costs.
Halnn Superhard, as the predecessor of superhard cutting tools, with more than 10 years experience on superhard cutting tools, have researched so many cbn grades for hard turning bearings depending on the long term technological strength. Especially for large scale wind power bearings with large deformation, Halnn researched BN-S200 solid cbn insert, have been accept by most manufacturers in this industry.
Compared with traditional cutting tools (carbide insert, ceramic cutters and coating insert), BN-S200 has more advantages. It not only can be used for large allowance, but also can be avoid the insert failure risk caused by the brazing tip fail.
For example, BN-S200 solid cbn insert fine finishing quenched bearings
Materials: 42CrMo (SCM440, 42CrMo4)
Hardness: HRC47~55
Machining Site: Raceway and End Surface
Insert Model: BN-S200 RCMX090700
Cutting Data: Vc=110m/min,Fr=0.45mm/r,ap=0.5mm
Machining Type: Dry Cutting
Comparing with ceramic cutters, the cutting speed of BN-S200 cbn insert can be 12% of ceramic cutters, and the tool life will be 8 times of ceramic cutters, and the roughness can reach Ra0.8.
With the development of the society, hard turning(turning instead of grinding) has become a develop trend, With cbn insert hard turning quenched bearings, it not only can improve the efficiency obviously, but also can ensure the product quality and reduce the tool costs.
