Abstract
The present disclosure provides a magnetic grinding device and a magnetic grinding control method, and relates to the field of machining. According to the device, a magnet platform of a grinding piece fixing table is connected with an electromagnet; the grinding piece fixing table is used for fixing a to-be-ground workpiece; an output end of a programmable power supply is connected with a coil of the electromagnet; a permanent magnet grinding rod is located above the to-be-ground workpiece; and a magnetic grinding control system is connected with the programmable power supply and is used for acquiring grinding points, on the to-be-ground workpiece, of the permanent magnet grinding rod, and controlling an output voltage of the programmable power supply by utilizing a removal amount of a blank workpiece surface shape of the to-be-ground workpiece, the grinding points and a pulse width modulation (PWM) control method.
