INTERNAL GEAR TYPE HONING GRINDSTONE, PROCESSING FOR GRINDSTONE, AND ALIGNMENT FIXATION DEVICE USED THEREFOR

摘要

PURPOSE:To make workable an internal gear type honing grindstone having high accuracy and sharply increase processing accuracy, operability, and productivity by forming fitting bolt inserting hole at an equal interval state in a circumferential direction to the side surface part of a grindstone. CONSTITUTION:A fitting bolt 8, inserted in the bolt insertion hole 7 of a grindstone 4, is temporary clamped to a support plate 10 side surface in which the grindstone 4 is provided on the tip part of the work spindle 9 of a lathe which is a cutting machine. At that time, when a bolt threadly engagement hole 15 is formed to a support plate 10, it is enough that a fitting bolt 8 is inserted into the hole 7 of the grindstone 4 and the bolt 8 is threadedly inserted into the hole 15 of the plate 10 to be temporary clamped. And the bolt 8 temporary clamped is normally clamped to be fixed to the plate 10 side surface in the condition where the alignment of the grindstone 4 is made. After that, the inner peripheral part and outer peripheral surface of the grindstone 4 in a fixed condition are subjected to cutting work to have given inner and outer diameters.
