振动扩孔纠偏机理与扩孔刀具形式研究

Study on reaming tool form and deviation correction mechanism in vibration reaming

为了解决工程中的扩孔纠偏问题,通过对振动扩孔纠偏机理的分析,找出合适的刀具形式,并进行扩孔试验。结果表明采用无导向刃的扩孔钻进行振动扩孔,可有效地提高扩孔纠偏的工艺效果。

In order to reduce deviation correction in reaming in practical applications, through analyzing correction mechanism of vibration reaming, the right form of the reamer and related experiments are presented. It is showed that an effective process effect improving deviation correction in reaming can be gotten by u- sing a new style of reamer without oriented edge on it.
