Abstract
PURPOSE:To provide a lapping tool which fits into a concave spherical surface to be lapped, by composing the shape of the lapping tool of a spherical portion with a flat part on the tip and a cylindrical portion continuous to the spherical portion. CONSTITUTION:A tool 10 for lapping a concave spherical surface B, which has a hole A at the bottom, comprises a spherical portion 11 whose diameter corresponds to that of the concave spherical surface B and which has a flat part 12 at the tip and a cylindrical portion 14 which is continuous to te spherical portion 11 and whose peripheral surface is perpendicular to the flat part 12. A holding rod 15 is secured on the cylindrical portion 14. The diameter D1 of the flat part 12 is 0.8l1 to 1.2l2 and the diameter D2 of the cylindrical portion 13 is 0.7Do to 0.95Do where l1 denotes the distance between the edge (k) on the bottom hole A and the peripheral edge (j) on the concave spherical surface B of a workpiece C, l2 denots the distance between the peripheral edge (j) of the concave spherical surface B and the opposite edge l on the bottom hole A and Do denotes the diameter of the spherical surface B. For lapping the spherical surface B, the tool 10 is rotated while it is inclined at theta which is 30 to 50 deg..
