CA9220车床是加工轴承内、外圈的专用车床。过去我厂加工实体保持架没有专用或改装过的搪球孔设备,是用C620-1和钻床加工球孔的,每搪一个孔都要重新装夹。分度、辅助时间长、工效低,当工件兜孔有椭圆要求时。工时还要增加一倍,精度也随着装夹的误差而有所降低。 CA9220 lathe is the processing of bearings, the outer ring of special lathes. In the past I plant processing entity cage no special or modified balling hole equipment, is to use C620-1 and drilling machine hole, each hole must be re-clamping a folder. Indexing, auxiliary long time, low efficiency, when the workpiece pocket oval requirements. Working hours have doubled, the accuracy is also reduced with the clamping error.
