CONCENTRIC GROOVE WORKING METHOD, CONCENTRIC GROOVE WORK-PIECE MANUFACTURED BY THIS METHOD AND CONCENTRIC GROOVE MOLDED ARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a concentric groove working method to work even a convex curved part in favorable surface roughness while working an sharp groove trough part by using a grinding wheel a head end of which is pointed by working a part a cross-section of which becomes a convex curve by an end surface part of a grinding wheel with a shaft and a part a cross-section of which becomes a straight line by a circumferential surface part of the grinding wheel with the shaft and a concentric groove work-piece to manufacture under this method by working by scanning the grinding wheel while changing inclination of a rotation axis of the grinding wheel with the shaft. SOLUTION: The part the cross-section of which becomes the convex curve is worked by the end surface part of the grinding wheel 4 with the shaft and the part the cross-section of which becomes the straight line is worked by the circumferential surface part of the grinding wheel 4 with the shaft by scanning the grinding wheel 4 with the shaft against the work-piece 1 rotating while changing inclination of a rotation axis 5 of the grinding wheel 4 with the shaft by rotating the work-piece 1 around a center of a concentric groove 2 as the rotation axis in the concentric groove working method to grind and work the concentric groove 2 the cross-section of which are made of the convex curve and the straight line by using the grinding wheel 4 with the shaft.
