Abstract (en)

[origin: JPH01216773A] PURPOSE: To flatly dress a grinding wheel and to avoid the production of spiral- shaped dressing grooves in the grinding wheel surface by obliquely projecting diamond needles from the circumferential surfaces, and overlapping their free ends in the circumferential direction. CONSTITUTION: Pocket-shaped recesses are provided on the circumferential surfaces 12, 13 of a dressing roll, the lower ends of diamond needles 15a-15h, 16a-16h are inserted into the recesses, the diamond needles 15a-15h, 16a-16h are fixed by an embedding compound in the obliquely projected state from the circumferential surfaces 12, 13, and the free ends 17, 18 of the diamond needles 15a-15h, 16a-16h are overlapped each other in the circumferential direction. A grinding wheel can be flatly and completely dressed by the dressing roll, and the production of spiral-shaped dressing grooves in the grinding wheel surface can be completely avoided.
