深孔钻削技术在机械制造业中正得到迅速地发展,尽管如此,人们对深孔钻削机理还了解不多。本文用快速停止试验法阐明了导向块在深孔钻削过程中的作用。得出了加工孔(?)面完整性的生成及它与加工过程的关系。在试验时,为了确定导向块上的挤压力和所消耗的能量,引出了比压概念。通过试验证明,深孔钻削质量与导向块的加工性能关系甚大,并将影响加工的经济性。 Deep-hole drilling technology is rapidly evolving in the machinery industry, though there is little to know about deep-hole drilling. In this paper, the rapid stop test method to clarify the guide block in the deep hole drilling process. The formation of the integrity of the machined hole (?) And its relation with the machining process are obtained. In the test, in order to determine the pressure on the guide block and the energy consumed, led to the pressure concept. The test proves that the quality of deep hole drilling has a great relationship with the machinability of guide block and will affect the processing economy.
