TRUING METHOD OF GRINDING WHEEL FOR GRINDING END SURFACE

摘要

PROBLEM TO BE SOLVED: To provide a grinding wheel truing method as a grinding burning preventive measure in thrust grinding of a side surface grinding wheel surface of a straight grinding wheel. SOLUTION: This grinding wheel truing method forms the proper number of concentric circles or spiral grooves around the axis to the side surface grinding wheel surface of the grinding wheel by (1) a relative displacement temporary stoppage in flat truing by radius changing directional relative displacement of the side surface grinding wheel surface of the rotating grinding wheel and a truer for contacting with this surface, (2) a cutout of the truer to the side surface grinding wheel surface at the relative displacement temporary stoppage in the flat truing by the radius changing directional relative displacement of the side surface grinding wheel surface of the rotating grinding wheel and the truer for contacting with this surface, and (3) the cutout of the truer to the side surface grinding wheel surface by a rotational locus around the axis to the side surface grinding wheel surface after the flat truing by the radius changing directional relative displacement of the side surface grinding wheel surface of the rotating grinding wheel and the truer for contacting with this surface.
