某型柴油机喷油器衬套加工工艺研究

Research on Machining Procedures of a Diesel Engine's Injector Lining

针对某型柴油机喷油器衬套材料改为42Cr Mo后,原摇臂钻床加工底平面的工艺方法已不能满足产品设计要求的问题,经多次工艺试验,改为在加工中心锪底平面的工艺方法。通过选定三刃螺旋硬质合金立铣刀具,优化工艺方案,确定合理的工艺参数,保证了产品的加工质量。

As the injector lining material of a certain diesel engine was changed into 42CrMo, the original machining method using rocker driller to process the bottom could not meet the product design require- ments anymore. By many times of tests, the machining center was chosen to carry out spot facing of the bottom. The machining quality was ensured by choosing the hard alloy spiral cutting tool, optimizing the machining programme and determining the appropriate machining parameters.
