Title:
MAGNETIC GRINDING APPARATUS AND MAGNETIC GRINDING CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2021/238792
Kind Code:
A1
Abstract:
The present invention relates to the field of machining. Disclosed are a magnetic grinding apparatus and a magnetic grinding control method. The apparatus comprises: a magnet platform of a ground workpiece fixing table is connected to an electromagnet; the ground workpiece fixing table is used for fixing a workpiece to be ground; an output end of a programmable power supply is connected to a coil of the electromagnet; a permanent magnet grinding rod is located above the workpiece to be ground; a magnetic grinding control system is connected to the programmable power supply; the magnetic grinding control system is used for obtaining a grinding point of the permanent magnet grinding rod on the workpiece to be ground and controlling an output voltage of the programmable power supply by using a removal amount of a blank workpiece surface shape of the workpiece to be ground, the grinding point, and a PWM control method. According to the present invention, the output voltage of the programmable power supply is adjusted by means of the removal amount of the blank workpiece surface shape, the grinding point, and the PWM control method, so as to adjust the magnetic field strength of the electromagnet, and the grinding accuracy is improved by changing the magnetic field strength in real time, fixing the grinding speed and the residence time of the permanent magnet grinding rod.
