Abstract:
1. A method for resurfacing a lapping plate, comprising the steps of: placing a resurfacing carrier with a holding hole on the lapping plate; holding within the holding hole a porous synthetic resin-based elastic member having a Rockwell hardness (HRS) in the range of −30 to −100; rotating the plate and the carrier individually; feeding loose abrasive grains onto the plate to provide said loose abrasive grains between said elastic member and said plate; and creating pressure between said elastic member and said plate while said loose abrasive grains are between said elastic member and said plate and while said plate and carrier are rotating so that the surface of the plate is roughened with the elastic member in accordance with the coarseness of the abrasive grains, wherein said elastic member adjusts to said plate surface elastically.
