内燃机活塞销孔精密镗削工艺的研究

Research on precise boring process of pin hub bores for internal combustion engine pistons

零件的加工质量是保证机械产品质量的基础，它包括零件的机械加工精度和加工表面质量两大方面．零件的加工精度越高则加工成本相对越高，生产效率则相对越低．本文就内燃机活塞销孔精密镗削工艺，从机床、夹具、刀具和工件所组成的工艺系统的各方面进行科学的分析与研究，提出一系列工艺措施，以提高其加工精度。

The processing quality of parts is the base of the quality of the machinery products, it includes the machinery processing precision and processing face quality. The more the processing precision is higher, the more the processing cost is more expensive, and the production rate is lower. In this paper, techniques of pin hub bores for internal combustion engine piston has been analyzed scientifically from technical system composed of machine tool, cutting, clamp and part, and provided a series of measures which may improve processing precision so as to improve product rate and decrease the product coast.
