Summary:PURPOSE:To improve the cutting quantity of a bit by pushing and polishing the end portion of the swelled inclined face of a cutter against a moving belt having abrasive grains, then polishing the bit portion thereof with a fixed grinding wheel and finally carrying out the edge finish polishing of the bit by means of a buff polisher. CONSTITUTION:In an exclusive grinder, the bit portion of a cutter 1 on which a swelled inclined face 1a is formed is placed over two rollers and pushed against a belt on the surface of which diamond abrasive grains are formed to polish the end portion 1b through the high-speed movement of the belt. At this time, since the polishing is carried while slightly deflecting the belt, a curved face can be smoothly polished. Then, the bit is pressed against a rotating fixed grinding wheel on the surface of which diamond abrasive grains are fixed and a pulling action is carried out to give rough edge sharpening to the bit 1c. Then, buff polishing is carried out to sharply finish the bit edge 1d.
