加工精度是机械零件的一个重要指IJH标，在单件、小批生产规模的重机行业中．提高加工精度减少加工误差相对比较困难。这是由于影响加工精度的因素诸多，不易得到有一定规律的控制手段。但从以下分析中也可以得到一定的启示，仅供参考。1＃g＠加工精度的误差因素及综合分析1．l Machining accuracy is an important means of mechanical parts IJH standard, in the single, small batch production scale heavy machinery industry. Improve the processing accuracy and reduce the processing error is relatively difficult. This is due to the many factors that affect the machining accuracy, not easy to get a certain amount of control. However, the following analysis can also be a certain revelation, for reference purposes only. 1 # g @ error of machining accuracy and comprehensive analysis 1. l
