WORK GRINDING METHOD WITH CENTERLESS GRINDING MACHINE, CENTERLESS GRINDING MACHINE AND UPPER SIDE BLADE USED THEREFOR

摘要

PROBLEM TO BE SOLVED: To highly accurately grind even a work (w) having a small diameter by smoothly rotating while restraining vertical vibration of the work (w) without causing a scratch by a hard material in the peripheral surface part of the work (w). SOLUTION: When grinding the peripheral surface part of the work (w) by using a centerless grinding machine having a support blade 18c in the lateral direction and arranging an adjusting grinding wheel on one of the front-rear sides of the support blade 18c and a grinding wheel in the other, a cover body (an upper side blade) 20 is formed for densely covering upper specific ranges g1 and g2 of the peripheral surface part of the work (w) supported by the support blade 18c in a noncontact state with these ranges, and grinding is performed while continuously supplying a grinding liquid boosted in pressure in the cover body 20.
