CENTERLESS GRINDING METHOD OF SHAFT MEMBER, AND MANUFACTURING METHOD OF CIRCULAR SHAFT MEMBER

摘要

PROBLEM TO BE SOLVED: To spread out a grinding fluid effectively and sufficiently to a grinding part for grinding a workpiece in the outer circumferential surface of a diamond grindstone, in the case where the workpiece of a shaft member comprising hard-to-cut materials such as ceramics is subjected to centerless grinding with the diamond grindstone.;SOLUTION: A plurality of grooves 18 extending in the circumferential direction are provided at intervals in the rotating axis direction of itself on an outer circumferential surface 16 of a grindstone layer 15 of a grinding wheel 10. The grooves 18 are provided, so that a grinding fluid is easy to turn around to the outer circumferential surface 16 of the grindstone in comparison with the case having no grooves, and thereby the grinding facilitation is achieved to obtain an effect such as the life elongation of the grindstone.;COPYRIGHT: (C)2014,JPO&INPIT
