PURPOSE:To automate the superfine finishing work by fixing a cutter whose main cutting edge surface is roughly ground, onto a loading base and determining the grinding quantity from the retreat quantity in the case when a rotary grindstone is pressed onto the cutter top edge surface of the cutter and carrying out grinding work in plural times, revolving the rotary grindstone in the longitudinal direction of the cutter. CONSTITUTION:A cutter 1 having the main cutter surface which is roughly ground by a knife grinder separately arranged in fixed onto a loading base 4, and the grinding quantity is determined by regulating the retreat quantity in the case when a rotary grindstone 36 is pressed onto the cutter top edge surface of the cutter 1, by the fluid pressure. After the fluid pressure is once removed, the rotary grindstone 36 is retreated from the cutter top edge surface, and d turning moment is applied onto the rotary grindstone 36 from a waiting position, and the grindstone 36 moved in reciprocation in the longitudinal direction. When the rotary grindstone 36 reaches the edge part in the longitudinal direction of the cutter 1, the fluid pressure for the cutter top edge surface of the rotary grindstone 36 is once released during the detection and reciprocating movement, and the rotary grindstone 36 performs the copying grinding work by an optional number of times. |
