超高速エアタービンスピンドルについて

抄録

In the cutting and grinding of ultra-precision, higher demand such as high precision, improved surface finish and so on have been required increasingly as our market situation. To meet those demands, high speed machining is quite effective through our reserch experiences, and the technology can also improve the productivity and the life of small tools. The actual theme is how we apply this technology for our development and improve the efficiency of our factory state dramatically as challenge. In order to realize the high-precision and high speed machining using small tools in the field around Max.100,000min^-1, we have developed the "ABT-1000". This spindle have a high rotational force with low energy consumption and a small size body. Also it has a sophisticated monitoring function which is useful to detect the spindle speed. This paper introduces the features of this "ABT-1000".
