TNGA110304 Brazing CBN Tools High speed Cutting Gray cast iron Brake Rotor

1. Halnn Tools Brazing CBN Tools High speed Cutting Gray cast iron Brake Rotor

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 Brazing CBN Tools High speed Cutting Gray cast iron Brake Rotor

Improve Efficiency: Can realize high speed machining,and the suitable linear speed is 250~450m/min for roughing process, 450~800m/min for finishing process. And it also be suitable for the high speed milling with 1500m/min or above.

Improve Tools Durability: The tool life of Halnn CBN Insert is about 15 times of carbide insert.

Characteristics of Halnn CBN inserts: BN-S300 adopt non-metal adhesive, not only extend the insert lifetime, but also improve the impact resistance,and BN-S300 can be used for finishing process.
