由发动机产品特性分析机床精度要求

Accuracy requirement analysis for CNC based on powertrain characteristic

目前主流合资车企都采用加工中心组成的柔性生产线来加工缸体、缸盖及变速箱壳体等箱体类零件,根据发动机箱体类零件产品特性,工艺特性及验收标准,分析对机床各项精度等级选择的原因,为机床改造可行性提供参考。

The mainstream joint venture automobile enterprises use CNC to process box parts such as cylinder block,cylinder head and gearbox. This document analysis whether a accuracy grade of machine can meet the requirement of a specific process according to the product characteristics,process characteristics and acceptance standards of engine box parts. So that we can provide guidance for refurbished CNC project.
