图1所示的液压接头,材料为尼龙,在该工件一侧有3个锥度部位需要加工,分别是图中标示的锥孔1、锥孔2和外锥面,该零件在使用时,锥孔2需要和芯柱零件实现无间隙配合,才能防止液压油的渗漏,因而其加工精度要求较高。在使用普通车 Figure 1 shows the hydraulic connector, the material is nylon, there are three taper parts on the side of the workpiece need to be processed, respectively, shown in the tapered bore 1, tapered bore 2 and the outer cone, the parts in use, the cone Hole 2 and the need to achieve seamless clearance with the stem parts, in order to prevent the leakage of hydraulic oil, and therefore its machining accuracy higher.
