Finishing of Gray Cast iron Brake Rotor with CBN Cutters

Finishing of Gray Cast iron  Brake Rotor with  CBN Cutters

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.

Why Choose Halnn Tools CBN Cutters?

For machining brake disc, the cutting tools materials include carbide alloy insert, coating carbide insert and cbn insert in the market. And only cbn insert can realize high cutting speed, and the performance advantages are higher than carbide insert and coating carbide insert, is the right tools for high speed cutting brake disc.

1) High Hardness, Good wear resistance, which will be about 15-20 times of carbide insert.

2) It can obey high cutting speed, the linear speed can reach 1500m/min, which improved the efficiency.

3) CBN Insert use dry cutting methods, no need to add cutting fluid, the chips can be Recycling easily. It reduces the pollution and lowers the tools costs.

4) CBN insert can help CNC lathe realize high speed cutting brake disc.
