Title:
MAGNETIC POLISHING METHOD
Document Type and Number:
Japanese Patent JP3030952
Kind Code:
B2
Abstract:

PURPOSE: To highly miniaturize a magnetic abrasive device, automate a polishing process, and provide a uniform polished surface by forming ferromagnetic body particles separately from abrasive grains.
CONSTITUTION: In a magnetic abrasive method formed of a yoke 3, an exiting coil 4, a power source, magnetic poles 6 opposed to a material 7 to be polished, ferromagnetic body particles 8, and abrasive grains 9 hardened with an oily wax 10, in which the material 7 to be polished and the magnetic poles 6 are relatively oscillated while generating a magnetic field between the magnetic poles 6 opposed to the material 7 to be polished, the abrasive grains 9 mixed with the oily wax 10 is charged between the magnetic poles 6 and the material 7 to be polished separately from the ferromagnetic body particles 8.
