摘要
由于气缸盖中喷油器衬套材料改为42CrMo,材料又硬又黏,采用原工艺方法加工在摇臂钻床加工底平面,已不能满足产品图样要求,现改为在加工中心锪底平面,通过多次工艺试验,选定了三刃螺旋硬质合金立铣刀具,优化了工艺方案,确定了合理的工艺参数,为产品的研制和批量生产提供可靠的技术支持。
The kinds of cylinder head 42CrMo to the injectcor sleeve material.The materials are hard and sticty,the original process method using radial machine processing in the basal plane,and can not meet the product design requirements,now countersinks in the processing center to the bottom plane.Through multiple technology test,selected three-blade helix carbide milling cutter,optimize the process plan,and determine the reasonable process parameters,provide reliable technical support for product development and production.
