The clamp device 34 to which the 4 is attached is rotated in the direction D during polishing.
(FIG. 1) is swung in the direction D, and a rounded polished surface with a clearance angle is obtained. For this reason, after one side is re-polished by mounting the tool at the protruding portion 35 having the mounting hole 35a, the tool is rotated 180° for re-polishing while swinging in the direction D each time the tool is polished at the other side.
When the clamping device 34 is used for re-grinding drills for grinding flat slopes, the insert screw 49 is inserted into the arcuate slits 5 of the projections 35, 36.
The shaft is fixed in a desired swinging position by connecting the shaft 50 and 51 with nuts 52 and 54 to reliably prevent twisting for surface polishing, and is free to slide in the direction A (FIG. 1) for polishing.
