一、引言对光洁度要求▽8～▽10的孔,通常采用精磨、抛光、研磨或珩磨等工艺方法作为终加工工序,这些工艺方法目前都存在着不同程度的缺点。我公司利用车床超精研磨筒形件深孔,光洁度能稳定的达到▽9～▽10,并且生产率比手工研磨高5～6倍,设计不同型式的研磨头后,许多零件可以不用抛光、研磨、珩磨加工。图1为用超精研磨加工的一部分零件,表1是与其它工艺方法经 First, the introduction of the requirements of the finish ▽ 8 ~ ▽ 10 holes, usually grinding, polishing, grinding or honing process as a finishing process, these processes are present there are varying degrees of shortcomings. Our company makes use of the deep-hole of the ultra-fine grinding cylindrical parts of the lathe, and the smoothness can reach ▽ 9 ~ ▽ 10 steadily and the productivity is 5-6 times higher than that of the manual grinding. After designing different types of grinding heads, many parts can be polished without polishing Honing process. Figure 1 for the use of ultra-fine grinding part of the workpiece, Table 1 is the other with the process of
