Abstract

PURPOSE: To provide equipment for lapping a concave spherical surface with high accuracy, by pushing a convex spherical part on the concave spherical surface of a workpiece and using a link mechanism to cause rotation, revolution and swing.
CONSTITUTION: A workpiece 6 is set on a workpiece rest 4. An air cylinder 2 is elevated so that the convex spherical part 18a of a lapping tool 18 is put in contact with the concave spherical surface 6a of the workpiece 6 under prescribed pressure. When a motor 12 is driven, a rotary disc 13 is rotated to revolve and rotate the lapping tool 18 through a connecting member 15, a rod 16 and a joint 19 with the rotation of the disc 13. The workpiece 6 in pressure contact with the lapping tool 18 is also rotated with that of the tool 18. Since a swing plate 9 is rocked by a swing mechanism provided on a first disc 20, the lapping tool 18 swings while it revolves and rotates. This results in lapping the concave spherical surface 6a of the workpiece 6.
