Introduction to grinding machines A lapping machine is a grinding machine that grinds the surface of a workpiece with a grinding tool coated or embedded with abrasives. It is mainly used for grinding high-precision flat surfaces, internal and external cylindrical surfaces, conical surfaces, spherical surfaces, threaded surfaces and other types of surfaces in workpieces. The main types of grinders are disc grinders, rotary shaft grinders and various special grinders. The grinding mill control system is controlled by PLC as the control core and text display as the human-machine dialogue interface. The human-machine dialogue interface can dialogue with people on information such as equipment maintenance, operation and failure; the operation interface is intuitive and convenient, with program control and simple operation. All-round safety consideration, non-normal state of the misoperation is invalid. Real-time monitoring, fault and error alarm, easy maintenance.
