1. Halnn Tools CBN Cutting Tools Machining Brake Disc

As the main component of the car, the brake disc is a powerful guarantee for safe driving. With the continuous updating of the automotive industry, higher requirements are placed on the tools for machining brake discs.Halnn Tools has successively launched the new material CBN inserts BN-S300/BN-K30/BN-K20/BN-K10,as the replacement tool materials.

2. Why we Choose Halnn Tools CBN Cutting Tools ?

Halnn researched 4 type CBN inserts grades specific for machining brake disc which can meet their requirements on the process and the surface roughness. The following will share you 4 kinds of CBN inserts.

(1) For roughing process: BN-S300 will be your right choice, the advantages: large cutting depth,

good wear resistance and long tool life.

(2) For finishing process:BNK30, BN-K20and BN-K10 can be the right choice, BNK30 can be made of both brazing and solid type, it has sharp cutting edges, high precision and long tool life. BN-K20 belong to brazing CBN insert, it has multi-cutting edges, will be more economic.BN-K10 belong to PCBN insert.
