Abstract

PURPOSE:To contrive an improvement in accuracy of a pitch space between spherical surfaces and eccentricity on the spherical surfaces and a reduction in man hours to be required for processing and assembling, by a method wherein a block body is held by a specific working jig and a spherical and large number of recessed parts corresponding to a lens part of an optical element are processed and formed on the top of a block body. CONSTITUTION:An unprocessed block body 11 is fitted in a notched recessed part 15a of a jig body 15 of a processing jig 14 along with end face press jigs 18a, 18b and fixed to the jig body 15 with a face press jig 17 and screw 16. A bottom press jig 22 is fitted to the jig body 15 with a screw 21, and a top lid 20 is fitted to the jig body 15 with a screw 19 after the top lid 20 has been positioned with a press in pin 24 and covers the top 11a of the block body 11. The block body 11 is fixed in a longitudinal direction further with a screw 23 and holding and fixation of the block body 11 to the processing jig 14 are completed. Then the block body 11 is fixed to an electric discharge processing machine 25 through the processing jig 14, electric discharge processing of the block body 11 along with the top lid 20 is performed with a processing electrode 26 and a spherical recessed part 13 is formed on the top 11a of the block body 11.
