CBN tools for machining grey iron brake discs for motor vehicles




Roughing and finishing brake discs. The tool shanks are made of high quality tool steel with high strength and steel properties through heat treatment! Turning inserts are made from high abrasion resistant PCBN composite material imported from abroad, and through leading modern intelligent resharpening technology, better dimensional stability and minimum delivery times are ensured! For highly abrasion resistant workpiece materials, turning inserts are specially chamfered and passivated to ensure better tool life and surface finish, improving tool cost performance and reducing customer production costs per item!
