We have developed machining centers, equipped with damping mechanism, for precision molds, which can not only suppress vibrations during high-acceleration driving of the machine but also perform high-precision and high-efficiency machining in micro regions. We have also achieved automatic exchanges of tools by employing ultrafast rotating main shafts with air hydrostatic bearings and automatic shrinkage fitting methods, as well as we have realized automated operations of the machine by integrating work with tool-measuring system.
