METHOD AND DEVICE FOR SUPER PRECISE CENTERLESS GRINDING

摘要

PROBLEM TO BE SOLVED: To efficiently perform centerless grinding finishing for a plurality of tapered surfaces having different tapered angles with super high precision of less than 0.1 microns at a low cost. SOLUTION: A preliminary finishing part P and a super high precision finishing part F constituted of two pairs of centerless grinding mechanisms having the same shape and dimension are installed in parallel on a common bed B. A workpiece (not illustrated because the workpiece is very small in a scale of this figure) is preliminarily finished with high precision (micron order) by the preliminary finishing part P. The centerless grinding finishing is performed for a tapered part with super high precision by the super high precision finishing part F. COPYRIGHT: (C)2004,JPO
