昆明水泵厂采用一套图示的专用镗杆,加工密封环槽,效果较好。镗杆3通过滑动定位轴承5,以填料孔定位,用轴承压盖4压紧。槽的轴向距离靠刀盘左右的D面与轴承5的C面定位。割槽镗刀7装于活动刀排8的方孔内。加工时,摇动手柄1,使丝杠锥度顶头9前讲,推动活动刀排8作径向走刀运动。当锥度顶头移动到一定位置,即当φ20的圆柱面与刀排8接触后,进刀停止,此时,即槽已加工至要求的尺寸。密封环槽分粗、精两次加工完毕,粗加工时,槽深留0.2～0.3毫米,槽宽留2～3毫米加工余量。
Kunming Pump Factory uses a set of special boring bar, processing seal ring groove, the effect is better. The boring bar 3 is positioned by the packing hole by sliding the locating bearing 5 and is pressed by the bearing gland 4. The axial distance of the groove is located by the left and right D surfaces of the cutterhead and the C surface of the bearing 5. Cutter boring knife 7 mounted on the movable knife row 8 square hole. Processing, shaking the handle 1, the screw taper head 9 before speaking, to promote the activities of the knife 8 for radial walk movement. When the taper head moves to a certain position, that is, when φ20 cylindrical surface and knife row 8 contact, the feed stops, this time, that is, the groove has been processed to the required size. Sealing ring groove coarse, fine finishing two times, roughing, leaving 0.2 to 0.3 mm deep groove, groove width left 2 to 3 millimeters allowance.
