可微米级调整的新型镗孔工具

New Boring Tool Can be Adjusted in Micron Order

镗孔是精密孔加工的一种主要的工艺方法,精密孔加工一般都有比较严格的公差要求,其镗刀的径向尺寸应控制在微米级范围内,并能快速实时、在线进行调整。应用传统的镗孔工具进行加工比较困难且耗时较多。文章介绍了一种由德国开发并已广泛使用的、可定量调整镗刀径向尺寸的镗刀夹结构和使用方法,分析了它的结构特点。

The machining accuracy is strict in bearing hole machining of solid of nonrevolutiong especially of cabinet part. To measure up to the given tolerance, the size of boring tool should be in micron order and can be adjusted quickly. The conventional tool is inefficient. The new boring tool can meet up to a high precision easily used in both manual and automation equipment.
