Paper Abstract

In this paper, an experimental instrument for large-scale optics grinding is introduced, which is a three-axis CNC precision grinding machine. After resolving several essential technological problems (grinder dressing and dynamic balancing, positioning of large-scale optics and profile measurement) in precision grinding of large-scale optics, many experiments are carried on the workpiece of 330mm square K9 optics by applying the experimental instrument. Typical process values in grinding flat and spherical optics include: X-axis feed rate is 15-200mm/min, grinding depth 2-30μm, 1400-2000 rpm spindle speed for grinder and workpiece spindle speed of 40-150 rpm. The grinders are 250mm diameter resin bond with 8-10μm to 80-90μm diamond abrasives, used in rough or finish grinding. Experiment results are presented. The PV surface form of flat and spherical optics is 3-4μm, 4-5μm respectively.
