Experiment Research on Grinding of Optical Glass with Indigenously Developed Monolayer Brazed Diamond Grinding Wheel

Abstract

Conventional grinding of optical glass will normally result in not only much lower material removal rate but also short service life of grinding tools, which causes the high fabrication cost of optical glass. This paper focuses on the precision grinding of optical glass with the indigenously developed monolayer brazed diamond grinding wheel. Before grinding process a precision dressing is conduct. The dressed grinding wheel topography is observed. Through precision dressing the grinding process achieves moderate surface finish as well as ensures certain grinding efficiency. The ground surface of the optical glass workpiece is made up of micro-pits and glazing zones and the obtained surface roughness variation with the process parameters is analyzed. The experiment shows that the developed diamond grinding wheel is suitable to the application of optical glass machining.
