Abstract
A photo-reactive grinding wheel 1 is irradiated with light by a light irradiation device 2 which is provided opposite to the grinding wheel, to bring about a chemical reaction and change in property, and dissolved/removed by a solution 4. Simultaneously, a workpiece 5 is processed by the photo-reactive grinding wheel 1. Thus, processing can be performed without causing clogging in the grinding wheel of a resin bond containing fine abrasive grains, high-grade surface roughness can be realized, and processing efficiency is relatively high. The controllability of the dressing is excellent, automation of dressing and in-process dressing can also be realized, a system which contains no metal ion in the whole processing can be designed, an expensive device is not required, and handling is easy.
