A surface grinder is a grinder that grinds the surface of a workpiece with a grinder coated or embedded with abrasives. It is mainly used for grinding high-precision planes, inner and outer cylindrical surfaces, conical surfaces, and other workpieces whose machining surfaces are flat surfaces.
1. The operating voltage of the motor of the plane grinder is 380V, and it is necessary to ensure that it is used under normal voltage.
2. The frequency of use of the motor of the plane grinder is 50HZ and cannot be used over 50HZ.

3. The current intensity of the motor does not exceed 15A. If it is found to be abnormal, it should be stopped and checked in time.
4. After the switch of the plane grinder motor is started, if it is found that the motor has no starting response in an instant, it should be stopped immediately for inspection, and it can be used normally after the fault is eliminated.
5. If it is found that the motor has dry noise or high temperature (above 80 ℃), it should be stopped immediately for inspection, and it can be used normally only after checking and eliminating the fault.
