PURPOSE:To enable the efficient polishing and lapping of a workpiece without changing the set position thereof by dismantling a grindstone from a vertical rotation axis after a polishing process and carrying out a lapping process with a lapping cloth fitted thereto and pressed to the surface of the workpiece. CONSTITUTION:A grindstone 3 fitted to the lower end of a vertical rotation axis 1 is shifted back and forth, and right and left, while being rotated in a condition pressed to the surface of a stainless steel workpiece. And a coolant is fed from within the rotation axis 1 via the center hole of the grindstone 3, thereby polishing the surface of the workpiece to a maximum roughness Rmax 0.18mum or less. Then, the grindstone 3 is dismantled from the rotation axis 1 and a lapping cloth 5 is so fitted instead as to be freely removable. And the lapping cloth 5 as pressed to the surface of the workpiece is moved back and forth, and right and left while being rotated, with a lapping liquid fed from the inside of the rotation axis 1 via the center hole 5' of the lapping cloth 5, thereby lapping the surface of the workpiece to a maximum roughness Rmax 0.1mum or less. |
