MAGNETIC ATTRACTION SYSTEM GRINDING METHOD

摘要

A magnetic attraction system grinding method and apparatus comprised of arranging a magnetic circuit forming means between an abrasive tool and a workpiece, thereby generating a grinding pressure required to grind the surface of the workpiece, and performing the operation of the abrasive tool through a rectilinearly reciprocating movement or rotary movement working along the workpiece surface during the application of grinding pressure while controlling either grinding speed or grinding stroke. The magnetic circuit is produced with an electromagnet or permanent magnet assembly and the abrasive tool may be a magnetic material bonded grindstone.
