PROBLEM TO BE SOLVED: To provide a centerless grinding technique of performing grinding work at a boundary edge part of a consecutive taper surface of a workpiece with high accuracy.SOLUTION: In a workpiece W having consecutive two taper surfaces t1 and t2, when performing the centering grinding of a boundary edge part e of both of the taper surfaces t1 and t2, both of the taper surfaces t1 and t2 are simultaneously subjected to grinding work by relatively performing infeed of a grinding wheel 1 having a profile corresponding to both of the taper surfaces t1 and t2 to the workpiece W supported and rotated, and rotating at high-speed. Then, one taper surface t2 of the taper surfaces t1 and t2 is subjected to the grinding work by further relatively performing infeed after the grinding wheel 1 is relatively moved in an axial direction to the workpiece W only by a predetermined amount. Thereby, the boundary edge part e of adjacent taper surfaces t1 and t2 can be subjected to the grinding work with high accuracy, in the workpiece W having the consecutive two taper surfaces t1 and t2. |
