CM6150精密车床,自从1965年试制,随后批量投产以来,络续发现了一些缺点及错误。特别是床头箱的主轴结构及溜板箱的油泵结构。主轴结构是采用典型的结构,但设计时未经深入分析,因此布置不够合理,致使装配时质量不能保证。油泵结构是测绘国外的,测绘时未作理论上的探讨,造成尺 CM6150 precision lathe, trial production since 1965, and then put into operation since the series continued to find some shortcomings and errors. Especially the headstock structure of the headstock and the pump structure of the slide box. The spindle structure is a typical structure, but the design time without further analysis, so the layout is not reasonable enough, resulting in the assembly quality can not be guaranteed. Oil pump structure surveying and mapping abroad, mapping did not make a theoretical discussion, resulting in ruler
