Experimental Researches on Precision Grinding of KDP Crystal

Abstract:

Article Preview

The KDP (Potassium Dihydrogen Phosphate) crystal, used as an important photoelectron part in the laser nuclear fusion system, is a typical kind of hard-to-machine material because of its soft, brittle, anisotropic property and nano-scale requirement for the shape and plane precision. Based on the experiments of the KDP crystal’s grindability, certain process parameters, such as the wheel granularity, the grinding depth and the workpiece’s feeding speed etc., and their influences on the grinding force and the surface roughness of KDP workpiece are analyzed. Furthermore, some KDP crystal’s typical surface damages in grinding are analyzed and some technical approaches to increasing the ultraprecision machining surface quality of KDP crystal are suggested as well.
