GRINDING WHEEL FOR MACHINING CONTOUR, AND GRINDING WHEEL SET FOR MACHINING CONTOUR, AND GRINDING DEVICE AND GRINDING METHOD USING THE SAME

摘要

PROBLEM TO BE SOLVED: To enable contour machining corresponding to a plurality of machining articles to one workpiece, and to greatly improve productivity without, for example, changing a structure of the grinding device so much.;SOLUTION: In the grinding wheels 3, 4 for machining contours, a plurality of contour machining surfaces (for example, circular arc surfaces 3a, 3b, or circular arc surfaces 4a, 4b) corresponding to the shape of the machining articles are formed on a single electro-plated grinding wheel. A projecting portion 3d or a projecting portion 4c is formed on the grinding wheels 3, 4 for machining the contours, and the machining articles 5, 6 are cut off and separated by these projecting portions.;COPYRIGHT: (C)2007,JPO&INPIT
