PURPOSE: To provide a grinding stone tip fitting type grinding wheel plate where a circular fitting part is provided on a diamond tip and the attachment/detachment is easy. CONSTITUTION: A grinding stone tip fitting type grinding wheel plate consists of a grinding wheel tip fitting plate on which a plurality of grinding stone tips 11 provided with a circular fitting part 13 are mounted and a holding plate, the grinding stone tip 11 is provided with an O-ring 14 on the fitting part 13 of circular section where a diamond tip 18 of circular section is joined on one end, an integrated projecting part 15 is provided on the top part of the fitting part, and the grinding stone tip fitting plate 12 is provided with a plurality of grinding stone tip fitting holes 16 which are symmetrically arranged. The fitting hole 16 is provided with a stepped hole consisting of a fitting part inserting hole 16a and a projecting part inserting hole 16b which is off-centered by the deviationδfrom the inserting hole, and a holding plate is provided with a plurality of holes to pass the diamond tip 18. The fitting part 13 of the grinding stone tip 11 is inserted into the fitting part inserting hole 16a of the grinding stone tip fitting plate 12 against the resistance of the O-ring 14, and the holding plate is inserted from the diamond tip 18 after the projecting part 15 is rotated and fixed to the grinding stone tip fitting late 12, and then, the grinding stone tip fitting plate 12 is connected to the holding plate.
