工程机械所采用的液压元件种类较多,其中一些液压元件上的复合孔尺寸较小,加工精度要求高,测量困难,在车床上采用车削方法很难加工。为解决此类工件的加工难题,采用阶梯铰刀铰削孔的加工工艺方法,通过对普通铰刀进行改制,并采取适当的加工工艺,可有效确保上述复合孔的加工质量,并满足加工效率的要求。 There are many types of hydraulic components used in construction machinery. Some of the hydraulic components have smaller composite holes, high machining accuracy and difficult measurement. It is very difficult to machine the lathe with the turning method. In order to solve the machining problems of such workpieces, the processing technology of the step reamer reaming hole is adopted. Through the reorganization of the ordinary reamer and proper processing technology, the processing quality of the composite hole can be effectively ensured and the processing efficiency can be satisfied Request.
