Abstract
A lapping tool capable of increasing the accuracy of a lapping operation, extending the life of lapping tool itself, adjusting a lapping diameter, and coping with the lapping operation of various diameters, comprising a lapping tool body having a lapping part on the outer peripheral surface thereof and slits provided in the lapping tool body axially between the tip part and the base part thereof.
Claims21
A lapping tool, comprising:
- a lapping tool body having a lapping thread part for lapping of a thread part by engaging with a thread part of an inner diameter part of a nut, and also having a tapered portion of which a diameter is gradually increasing from a tip side to a base side on the outer peripheral surface of said lapping tool body, wherein said tapered portion comprises a first tapered portion and a second tapered portion, and wherein the second tapered portion has an angle that is smaller than that of the first tapered portion;
- slits provided in said lapping tool body axially between a tip part and a base part of said lapping tool body;
- and
- an arbitrary number of lapping diameter adjustment members, being screwed inwardly in the radial direction, from an outer part of said lapping tool body, into said slits of said lapping tool body, and which adjust the diameter of said lapping tool body by pressing an end of said lapping diameter adjustment member against an inner surface of said lapping tool body.
