Method and grinding tools for precision centerless grinding shaft parts with advanced surface quality

摘要

a grinding tool 1 for high precision centerless grinding shaft-like workpiece 16 in a continuous process, at least, is provided with a single conical grinding region 3 and one cylindrical grinding region 4 . Conical grinding region 3 by its first grinding layer 13, although primarily intended for grinding a large amount of cutting, the conical grinding region 4, by the second grinding layer 14, mainly to achieve high surface quality generally it covers, it is not necessary to remove a large amount of cutting. Grinding layers 13 and 14, at least, have different abrasive used, CBN is used preferably conical region, the diamond is used in the cylindrical region. Further, a method of operating together with the grinding tool 1 of the present invention, which grinding shaft-like workpiece 16. Oversize and surface quality is at least temporarily at the same time grinding.
