According to the prospectus, corundum is a leader in fully direct-drive CNC machine tools in China. It is also one of the few domestic enterprises that have both PWM CNC systems and bus-type CNC systems, and both types of CNC systems have formed large-scale sales. The company's full direct drive CNC machine tools all use self-developed PWM CNC systems, which can solve the problem of shortfall restraint in high-end machine tools. During the reporting period, over 80% of the company's CNC machine tools were used in the three major fields of precision molds, aerospace and consumer electronics.
Up to now, more than 20,000 sets of CNC system products have been sold and used. They are used in precision milling machines, precision grinding machines, three-dimensional five-axis lasers, force-controlled grinding equipment, and automation equipment. They have replaced mainstream CNC systems such as Germany's Siemens, Germany's Heidenhain, Japan's Fanuc, and Japan's Mitsubishi, and already have a certain market popularity.
Among them, the U series PWM CNC system successfully broke Germany's monopoly on the Chinese machine tool market. In the domestic machine tool market, German Heidenhain and the issuer are the main suppliers of PWM CNC systems; in addition, due to its excellent performance and product stability, the issuer's N series bus CNC system has been successfully sold to many world-renowned automation solution companies, such as Fanuc Robotics.
