我厂加工的空压机连杆铜套(图1),内孔有4条油槽。原来小批量生产时,在车床上采用内孔刀把油槽拉出来,拉出来的4条油槽难以均布,且表面粗糙度也达不到图纸要求,既费工又费时。 后来,我们改进了加工工艺,采用车床铣油槽,具体做法:在CA6150车床中,拆去小拖板及刀架,安装一分度头,通过垫板调整分 I plant processing air compressor rod copper sleeve (Figure 1), the hole has four oil tank. The original small batch production, the use of the inner hole in the lathe to pull out the tank, pulling out of the four oil tank is difficult to uniform, and the surface roughness does not meet the requirements of the drawings, both time-consuming and labor-intensive. Later, we improved the processing technology, the use of lathe milling groove, the specific approach: In the CA6150 lathe, remove the small carriage and knife holder, install a sub-head, adjust the points through the plate
