摘　　要：采用四轴球体研磨方法对金属钛球进行精密研磨实验,通过Talysurf轮廓仪对球体表面粗糙度进行测试,通过靶丸表面轮廓仪检测钛球圆度。结果表明:钛球表面粗糙度可达小于10nm,圆度小于1.0μm。通过对球体的受力分析表明,在四轴空间对称分布的情况下,需满足四轴受力基本相同,研具半径为被研球体的0.816倍,可获得圆度较好的球体。The whole sphere lapping is important to fabrication of a metal capsule fhollow microspheref which is a vital part of the ignition target. In this paper, the metal titanium sphere was machined by using the four axis sphere lapping technique. The surface roughness was characterized by means of talysurf series 2 and the roundness by means of surface profile meter. The re sults indicated that the surface roughness of the part was less than 10 nm and the roundness was less than 1.0 μm.
