This article analysis the constructive features and technical indicators of engine cylinder tappet hole, introduce the variety of the processing technology in motor enterprises by now. And discuss the weak-ness of traditional process, which has low precision, poor chip removal and cooling and fixture complex. Base on the actual situation of mass production in motor enterprises, issue out gun drill &reaming applica-tion with high efficiency and precision, present valuable working process parameters. Also it can be a cer-tain reference value for other cylinder hole making.
