PURPOSE:To easily polish a fly edge with high accuracy without any influence of mounting error of fly edge, by holding the fly edge similarly to that in cut working, rotating it in the opposite direction to that of working and polishing the fly edge with the land portion being pressed against a grinding wheel. CONSTITUTION:A fly edge 2 is clamped by a tool holder 3 which is chucked by a chuck 4 of a spindle 5 of a working machine like a milling machine for preparatory plan, and a grinding wheel 5 is mounted on a table 6 of working machine. And the fly edge 2 is adapted to contact the grinding wheel 5 to be polished by the reverse rotation to the normal usage condition. Since the fly edge 2 in polishing is held similarly to that in the normal cut working and rotated in the opposite direction to same, the land 2b can be polished easily and accurately with-out any effects of mounting error of fly edge 2. As a result the fly edge bears accurately against the surface of a material to be ground to prevent it from the degradation of surface roughness. |
