CUTTER WHEEL, SCRIBING METHOD AND CUTTING METHOD FOR FRAGILE MATERIAL SUBSTRATE USING THE CUTTER WHEEL, AND METHOD OF MANUFACTURING CUTTER WHEEL

摘要

The invention concerns a method for manufacturing a cutter wheel (10C) for scribing a brittle material substrate, having the steps of forming a blade edge on a wheel (10A) in a disc form by roughly grinding the blade edge at at least one blade edge angle ¸1 and then forming the edge side of said blade (10B) by finely grinding the blade edge at a blade edge angle ¸2 which is different from blade edge angle ¸1. The invention further concerns a cutter wheel (10C).
