本文分析了内燃机活塞销孔液压加工中的问题;采用试验,统计方法找出滚压加工余量变化对表面粗糙度的影响规律,从而可为工艺编制提供可靠依据,保证加工质量。图1幅。
This paper analyzes the problems in the hydraulic machining of the piston pin hole in the internal combustion engine. The influence law of the variation of the rolling allowance on the surface roughness is found by the test and statistical method, which can provide a reliable basis for the process compilation and ensure the machining quality.
