导筒类薄壁件外圆磨削工艺

Outer Circle Grinding Process for Guide Cylinder Thin-walled Part

船用柴油机导筒组件在工作中需进行往复运动,其外圆圆柱度等形位公差要求较高。对于外圆,一般采用磨削加工。在分析外圆磨削精度影响因素的基础上,提出新的导筒类薄壁件外圆磨削工艺。介绍了新的外圆磨削工艺所使用的工装和装夹方法,并给出了实测外圆磨削精度。

The guide cylinder part of marine diesel engine is in reciprocating during work,and the outer cylindrical degree isomorphic tolerance is required to be high.For the outer circle,grinding is generally used.On the basis of analyzing the influencing factor of cylindrical grinding accuracy,a new outer circle grinding process for guide cylinder thin-walled part was proposed.The tooling and clamping method used in the new outer circle grinding process were introduced,and the measured outer circle grinding accuracy was given.
