Abstract

재료쇠(1)의 숫돌면을 형성하는 부분에, 대략 균일한 높이로 균일하게 분포하도록 다수개의 사각뿔형 또는 사각뿔대 모양의 돌기부(50)가 형성되어 있다. 돌기부(50)의 표면에는 돌기부의 높이 보다도 작은 입자 직경을 가지는 초 숫돌 입자(8)가 고정 부착되어 있다. 숫돌 입자(8)의 표면을 포함하는 숫돌면(2)의 외표면의 적어도 일부를 피복하도록, 피삭재의 용착을 방지하는 불소수지로 이루어진 피막(10)이 형성되어 있다. 숫돌멱(2)의 외표면이 피막(10)에 의하여 피복되어 있기 때문에, 절단감이 좋고, 게다가 절삭 가루가 숫돌 입자 사이에 가득 채워지는 일이 적고, 절삭 가루가 숫돌면에 용착할 우려도 대단히 적다.A plurality of square pyramidal or square pyramid-shaped protrusions 50 are formed in the portion forming the grindstone surface of the metal 1 so as to be uniformly distributed at a substantially uniform height. On the surface of the protruding portion 50, ultra abrasive grains 8 having a particle diameter smaller than the height of the protruding portion are fixedly attached. The coating film 10 which consists of a fluororesin which prevents welding of a workpiece is formed so that at least one part of the outer surface of the grindstone surface 2 including the surface of the grindstone particle 8 may be covered. Since the outer surface of the grindstone 2 is covered by the film 10, the cutting feeling is good, and the cutting powder is less likely to be filled between the grindstone particles, and the cutting powder may be welded to the grindstone surface.
