This is a CNC special purpose machine which incorporates two Modulo Equipe "1" units one opposite the other and 2 self-centering chucks, suitable for clamping special shafts. These units allow to work each individual part on both sides simultaneously and to perform turning operations by means of CNC rotary-tool turning heads, as well as all types of drillingtapping jobs. The bed and self-centering chucks are made of electro-welded metal plate, subjected to a stress-relieving treatment.
