New material for high-speed cutting brake discs - BNK30 CBN

As the main component to ensure the safe driving of the automobile, the brake disc not only has higher requirements on product 

quality, but also puts higher requirements on production efficiency. This high-speed cutting has become the processing technology

pursued by modern manufacturing. The realization of high-speed cutting brake discs requires the cooperation of tools to complete. 

As a tool that directly contacts the brake disc and processes the brake disc, its performance directly affects the surface quality and

production efficiency of the brake disc.

In this regard, Halnn has developed a new generation of high-speed cutting brake disc tool - BNK30 CBN grade inserts, which uses 

nano-scale binder and high-purity CBN particles to optimize the ratio, can be cut at 500-2000m / min cutting speed(Vc) .The 

high-speed cutting of the brake disc can meet the stable cutting of the brake disc parts, especially in the field of finishing. The tool life 

is doubled compared to the traditional carbide tool and the coated carbide tool. The specific form is as follows.
