新系列摇臂钻床是液压操纵和夹紧的,机床油管较多,如能采用尼龙管代替铜管,则能节省大量战备物资。但由于尼龙管管接头使用不可靠,常会压伤尼龙管喇叭口,而造成油管放炮,尼龙管管接头的质量问题,成了大量使用尼龙管的阻碍。国外资料介绍的管接头结构又都较复 The new series of radial drilling machine is hydraulic control and clamping, machine tool tubing more, if you can use nylon tube instead of brass, you can save a lot of combat readiness supplies. However, the use of nylon pipe joints is not reliable, often crushing the nylon pipe bell mouth, resulting in pipe blasting, nylon pipe fittings quality problems, has become a large number of obstacles to the use of nylon tube.
