As we all know, in metal cutting processing, the cutting tool and the material of the part being processed are contradictory. New materials require newer tools and newer methods to achieve efficient processing.In order to cope with and adapt to the increasing number of difficult-to-machine materials in the mechanical field and their requirements for processing performance, processing efficiency and processing accuracy,At present, the global tool industry is constantly improving the insert substrate, geometric angle, coating technology and processing methods to meet the efficient processing requirements of difficult-to-machine material part...
