Japan developed a CNC mill

Recently, Japan developed a CNC grinding machine, which can realize the automatic grinding and polishing of three-dimensional surface molds. Due to the complex shape of the mold cavity, any method of polishing has certain limitations. The development of special grinding and polishing methods, extrusion grinding, electrochemical polishing, ultrasonic polishing and compound polishing processes and equipment to improve the mold surface quality is a new direction of development. Japan developed a successful CNC grinding machine and solved the global problems of mold surface processing.
