Title:
METAL-COATED CUBIC BORON NITRIDE ABRASIVE GRAINS AND METHOD FOR PRODUCING THEREOF, AND RESIN-BONDED GRINDSTONE
Document Type and Number:
WIPO Patent Application WO/2004/061041
Kind Code:
A1
Abstract:
Cubic boron nitride abrasive grains which have been provided, on the surface thereof, with grooves having a ratio (w/d) of a width (w) to a depth (d) of less than 1 and a ratio (w/L) of a width (w) to a length (L) of less than 0.1, and then coated with a metal. The cubic boron nitride abrasive grains exhibit an improved holding power (binding strength) between the metal coating film and the cubic boron nitride abrasive grain, and thus can be used for producing a resin-bonded grindstone which exhibits the combination of a high grinding ratio (long life) and a low grinding power value (good cutting quality).
