Abstract
PURPOSE:To obtain the captioned wheel which develops the superior performance in working fireresistive bricks, etc. and with which the amount of abrasion can be reduced and the service life can be prolonged by pulverizing a diamond sintered body synthesized at high temperature and high pressure and using said substance as grinding grains. CONSTITUTION:Since the tungsten-carbide layer in the conventional method can be removed in sintering a diamond sitered body at high temperature and high pressure, the problems that the strength of tungsten carbide is remarkably reduced at an excessively high temperature and the life of a high-pressure container is shortened at high pressure are eliminated. Therefore, temperature and pressure can be varied freely, and the part made of tungsten carbide can be replaced with diamond powder in a same apparatus, and the larger diamond sintered body can be synthesized. The granular diamond which is sharp and has a high strength can be obtained, and the amount of abrasion can be reduced, and the life can be prolonged.
