RNMN060400 Solid CBN inserts High efficiency Rough Machining Gray Cast iron Brake Disc

1. Halnn Tools RNMN Solid Round CBN inserts Rough Machining Gray Cast iron Brake Disc

In previous times, people adopt common lathe and carbide insert to machine brake

disc, the process is roughing-semi-finishing-finishing. With the improved requirement on the surface quality and the production qty, they change the common lathe to CNC Lathe, but the carbide insert can’t machine with high cutting speed, they also can’t improve the efficiency, so they will choose other insert materials to satisfy the CNC lathe. CBN Insert became their right choice.

2. Why we Choose Halnn Tools RNMN Solid Round CBN inserts Rough Machining Gray Cast iron Brake Disc

In previous times, the main cutting tools for machining brake disc in China are carbide insert and coating carbide insert, and most of them use common lathe, it affects the processing efficiency seriously. In current times, with the development of the society, they change the common lathe to CNC Lathe, and it can be used with high cutting speed, so it must change the cutting tools materials to meet the lathe’s requirements. CBN Insert will be their right choice.

Halnn Tools, as the predecessor of superhard cutting tools industry, already researched superhard cutting tools more than 10 years, and launched 4 grades CBN inserts for specific for machining brake disc: BN-S300, BN-K20 BNK30 and BN-K10 CBN insert. They have obvious advantages for machining brake disc than traditional carbide insert.
