机床传动箱体中的轴孔,一般采用镗模来保证其加工后的精度要求。然而,镗模径长期使用后会逐渐失却精切,往往一孔之差,患殆全局。本文介绍一种简单、有效的修正镗模内衬套偏心的方法。一、偏心修正方法 1.实测数据分析 Machine tool transmission shaft hole, the general use of boring mold to ensure its accuracy after processing requirements. However, the long-term use of boring mold will gradually lose the precision cut, often the difference between a hole, suffering from the overall situation. This article describes a simple and effective method of correcting the eccentricity of a bored-in liner. First, the eccentric correction method 1. Measured data analysis
