1、前言振动切削就是在刀具或工件正常进给的同时,给它施加某种有规律的运动,从而改善切削条件。国外对振动切削的研究较早,日本从50年代初开始起步,到60年代便公布了振动切削的专利。目前,振动切削的理论基础和基本技术都已形成体系。采用振动切削已取得了理想的效果。国内从80年代初便有人研究振动车削、振动钻孔和振动精密铰孔等。在深孔加工方面,60年代就有了BTA系统内排屑深孔钻,钻削进给量δ=40～70mm/min,70年代又从瑞典引进了双管内排屑喷吸钻,钻削进给量提高到300mm/min。以上两种钻削方法,生产效率都比较高,钻出来的
1, the preface Vibration cutting is in the normal feed tool or workpiece at the same time, give it a certain regular exercise, thereby improving the cutting conditions. Foreign studies on vibration cutting earlier, Japan started from the early 1950s, to the 1960s will be announced vibration cutting patent. At present, the theoretical basis of vibration cutting and basic technology have formed a system. The use of vibration cutting has achieved the desired results. Since the early 1980s, some people have studied vibration turning, vibration drilling and vibration precision reaming and so on. In deep hole machining, there was a deep hole drilling in the BTA system in the 1960s. The feed rate of drilling was δ = 40-70mm / min. In the 1970s, a dual-pipe chip jet drill was introduced from Sweden. Feed rate increased to 300mm / min. The above two drilling methods, the production efficiency is higher, drilled out
