ELECTROFORMED THIN BLADE GRINDSTONE AND ITS MANUFACTURE

摘要

PURPOSE:To make it possible to obtain excellent cutting sharpness and high processing accuracy from the beginning of grinding by making super fine abrasive particles project from the surface of a peripheral cutting edge part of a metallic plating layer by 1/5 or more of average particle diameter of the abrasive particles. CONSTITUTION:Super fine abrasive particles 11 are made to project from a surface 10a of a metallic plating layer 10 on each of both surfaces and a peripheral cutting edge part by a projecting amount H of 1/5 or more of average particle diameter. By setting the projection amount H in this way, excellent cutting sharpness and high processing accuracy can be obtained from the beginning of grinding.
