BNK30 Brazing CBN/PCBN Turning Inserts for Continuous Cutting Turning Brake Disc 

With the vigorous development of the automotive industry, the demand for brake disc products has increased year by year. As a key component of the car brake system, the brake disc is a powerful guarantee for safe driving. Processing efficiency and quality are especially important for the manufacture of brake discs.
