磷酸二氢钾晶体的立轴端面可磨性研究
Study on grinding KDP crystal with the vertical spindle face grinding machine
摘要
Abstract
Potassium dihydrogen phosphate ( KH2 PO4 or KDP) , an recognized optical crystal , has been widely used in laser nuclear fusion projects due to its good quality of large electro-optic coefficient and large diameter( ≥400 mm) . From growth to processing into optical element , it requires procedures of cutting , precision machining , ultra-precision machining , coating and so on , and the processing period is long . In this paper , the grinding process of the KDP crystal is carried out using the vertical spindle face grinding machine . The influences of different particle sizes resin bonded diamond wheels ( D 7 , D36 , D91 , D151 ) on the surface roughness and surface micro-topography under different processing parameters ( spindle speed , feed speed , grinding depth) are compared . The feasibility of KDP crystal grinding is studied which lays the foundation for realization of grinding instead of turning ( polishing) and shortening the manufacturing cycle of KDP optical elements .关键词
