Zusammenfassung:	FIELD: mechanical engineering; lapping flat surfaces of parts of shut-off fittings both during manufacture and repair. SUBSTANCE: proposed device has lapping disk mounted on base for rotation. Cassettes provided with seats for placing parts to be lapped are mounted on working surface of disk between central and peripheral rollers. Peripheral ring is mounted on base coaxially relative to disk for performing turn. Each peripheral roller is articulated with base through single-arm lever. Peripheral ring is provided with at least one cam in area of motion of each lever. Cam is connected with ring on side of lever for engagement during turn of ring. Such construction simplifies mechanism of unbraking of cassettes on lapping disk. EFFECT: enhanced operational safety. 3 cl, 6 dwg
