摘　　要：针对传统的不锈钢液压支架电液控制阀主阀加工工艺存在的加工精度低、生产效率低以及生产成本高等问题,研究一种应用五轴数控加工中心和计算机辅助制造软件HyperMILL进行数控编程加工主阀阀体的工艺方法。一次装夹,依次完成工件5个面的铣削及钻孔、镗孔、倒角、铣螺纹等工序。通过工艺分析和加工试验证明:该工艺方法可以减少装夹次数,减少工人体力消耗,节省辅助加工时间,同时保证定位精度,提高液压支架电液控制阀主阀阀体加工效率至少一倍,具有应用推广价值。Aiming at the problems of low processing accuracy, low production efficiency and high production cost in traditional technique for electro-hydraulic valve of stainless steel hydraulic support, a new technique method for the main valve body processing was studied by using five-axis machining center and CAM software HyperMILL.The processes of milling, drilling, boring, chamfering and thread milling to five surfaces of a workpiece were completed successively by just one clamping. Through analysis and processing test, it is proved that the technique can reduce labor consumption, save auxiliary processing time and clamping times, ensure positioning accuracy, improve the processing efficiency of the main valve body of an electro-hydraulic valve of hydraulic support by at least one time, and has application and promotion value.
