摘　　要：研制了一种用于KDP晶体侧棱加工的磨削+飞切组合加工装备,该装备采用气体静压主轴与气体静压导轨,同时设计专用的高刚度角度调节机构,以适应不同侧棱角度的加工。该装备解决了现有KDP晶体侧棱加工中加工效率和精度的问题。经实验测试,获得了KDP晶体侧棱面的高精度粗糙度指标(2.4 nm),同时采用磨飞组合加工效率为单纯飞切加工的7倍。In this paper,machining equipment combined with grinding and flying cutting for a KDP crystal is developed.The aerostatic bearing spindle and aerostatic bearing guide are adopted in the equipment.In order to adapt to the processing of different edge chamfer,a special high stiffness angle adjustment structure is developed.The equipment solves the problem of processing efficiency and precision in the processing of the existing KDP crystal.Through experimental test,the high precision roughness(2.4 nm)of the KDP crystal side surface is obtained.At the same time,the combined processing efficiency of the flying and grinding is 7 times that of the only flying cutting.
