FORMATION OF SUPERABRASIVE GRAIN GRINDSTONE BY MIST ELECTRIC DISCHARGING

摘要

PURPOSE:To efficiently perform the truing and dressing of a super abrasive grain grindstone without the destruction of the abrasive grain by spraying a mist like liquid mixing air and water or water soluble liquid to the contact part between an electrode and the superabrasive grain grindstone. CONSTITUTION:A rotating superabrasive grain grindstone 2 is approached to an electrode 15. A mist like liquid mixing air and water or a water soluble liquid is then sprayed from a nozzle 11 to the contact part between the electrode 15 and superabrasive grain grindstone 12 and the formation of the superabrasive grain grindstone is performed.
