Filed: 1988-01-25
Abstract: PURPOSE:To perform lapping of a thin and deformable material with high precision by carrying out the lapping, keeping the noncontact state between the worked material and a work holder by applying an air pressure from the back surface of the worked material. CONSTITUTION:A work 1 in the fitted state onto a work holder 4 is mounted onto a lap surface plate 3, and lapping is carried out. In this case, the work 1 is fitted inside a projection 41 formed on the outer periphery of the undersurface of the work holder 4. In this state, a gap is formed between the work 1 and the work holder 4 by feeding air onto the work 1 from the back surface. Therefore, the work 1 can be lapped with high precision free from deflection, maintaining the noncontact state between the work 1 and the work holder 4. Even if a stress is applied during the lapping, the work 1 is freely deformed by adjusting the air pressure to a proper value, and the flatness of the work 1 can be sufficiently improved.
