PCBN Insert for hard turning bearings : BN-H20 and BN-H11 PCBN Insert from Halnn Tools

PCBN Insert for hard turning bearings : BN-H20 and BN-H11 PCBN Insert from Halnn Tools

 Bearings are one of the most importance components of the machine tools and the whole machine industry. And with the increasing competition on this industry, the heat treatment technology is improved, which improve the tool life. And the hardness of the bearings after heat treatment is high, and difficult to machine.

In the process of machining bearings, it is divided into 3 types: continuous turning, semi-interrupt turning and heavy interrupt turning condition according the different machining site. And it is difficult for heavy interrupt turning condition, especially for the large scale bearing 

As we all know, cutting tool is one of the most important tools in machine industry,

chosing the suitable cutting tools can help you improve the efficiency and save the tool cost.

Halnn Superhard, with more than 10 years experience on superhard cutting tools, pay more attention on machining pcbn tools and pcd tools, has research special cbn grades for hard turning, heavy turning hardened steel and high speed cutting cast iron industry.

Specific for bearing industry, Halnn research BN-S20, BN-S200 and BN-H11 PCBN Insert , they can be used for roughing, semi-finishing and finishing process, they can ensure the high quality, improve the efficiency and reduce the production costs.

BN-S20 and BN-S200 belong to non-metal adhesive cbn insert, has strong impact resistance, and can machine bearings with large allowance, Bn-H11 belong to brazing pcbn insert, mainly used for finishing process, and the cutting depth need to control within 0.3mm.

The cutting parameters as follows:

One of the application case as follows:
