The machine adopts short section huge roller chain transmission pressure plate, the grinding head adopts ABB motor with high precision, small energy consumption, strong stability, PLC precision control of the width of the bevel edge, high degree of automation, and the use of synchronous belt transportation. It is mainly used for the inclined edge of the grinding speed, and the various combinations of the bevel edge. Fine grinding and polishing, as well as bottom edge grinding, are done in one pass. It has the characteristics of high processing efficiency, good quality, stable performance, simple operation and low loss.
