Abstract

PURPOSE: To rapidly and highly precisely grind a fitting surface of a part, by rotating the part thereby a receiving plate is caused to revolve.
CONSTITUTION: When a rotation transmission plate 30 attached with a valve seat 1 through a shaft 16 and a chuck 17 is slowly rotated by a motor 15, the valve seat 1 is rotated and together with it the receiving plate 20 is revolved since the fitting surface 7 of the valve seat 1, due to its own weight, is in contact with a lapping surface 19 of the receiving plate 20 on which an abrasive is applied. When the receiving plate 20 is rotated in this accomparying manner, the fitting surface 7 of the valve seat 1 is lapped by not rocal part but by all part of the lapping surface 19 of the receiving plate 20. Accordingly, the rubbing surface 19 of the receiving plate 20 cannot be locally weared, and therefore the fitting surface 7 of the valve seat 1 can be precisely ground.
