China) Abstract : By means of improving the quality of CNC lathe spindle precision. the spindle precision changing rules in the procedure of cold inspection. heat inspection and load test . and the accuracy of the optimization method were expounded. which al50 improved the range of the spindle box consistency and achieved the improving of product quality and eHiciency. Nowadays. with the generalization of CNC. lhe applicalion of CNC machining and CNC equipments have developed rapidly. the ta lents w ho grasp CNC technology have coming more and more . the book s about CNC programming and real operalion have also coming more and more. But the spindle box as the key parl of CNC equipmenlS lhat can aHecl operalion properly got little inslruclion. especially in precision index inspection and later maintenance ways. Key words : spindle accuracy. cold inspection. heat inspection. load test 轴精度指标如下: 1)主轴定心轴颈(7。小锥)径向跳 l 主轴箱的工艺现状 动ζ0.008 mm ; 2) 主轴轴肩支承面跳动ζO. 016 机床行业具有特殊性，目前主要有 2 个国家行 mm;3) 主轴近端径
