METHOD FOR MANUFACTURING EXPOSURE LENS

摘要

PURPOSE: A method for manufacturing an exposure lens is provided to improve the productivity of the product by installing a machining member of an exposure lens on a rotary table. CONSTITUTION: A machining member(14) is set to a rotary table(6) of a jig(8) which is inclined. A tool(12) is mounted to a rotatable main shaft(2). The rotary table(6) is rotated to machine one surface of the machining member(14). The main shaft(2) is moved horizontally and vertically. The tool(12) machines one surface of the machining member(14).
