Abstract

PURPOSE:To permit a large quantity of tiny thin leaves to be simultaneously machined into a highly accurate thickness by lapping the surfaces of workpieces bonded on a surface plate, before transferring them to another surface plate to machine the reverse surfaces. CONSTITUTION:The tiny leaves 1 of a workpiece are bonded, by means of thermoplastic bonding agent 6, on the first surface-plate 5 having a vertical through hole 4 in its almost central portion, and the surfaces of the tiny leaves 1 are lapped. Then bonding agent 10 capable of dissolving in a solvent is applied to minute bonding- agent guide channels 8 on the second surface-plate 9 to bond the surfaces of the tiny leaves 1 to the second surface-plate 9. After that, the thermoplastic bonding agent 6 is softened on heating in order to remove the first surface-plate 5 from the reverse surfaces of the tiny leaves 1. The reverse surfaces are lapped and mirror-finished before the bonding agent 10 is removed by using the solvent, and then both the surfaces are mirror-finished to obtain tiny thin leaves.
