ABSTRACT:
The invention relates to a machine tool, in particular for the manufacturing, from sheet metal of mechanical parts such as pulleys, wheels and similar.
It comprises a first chuckhead quill (4) rotatably mounted to a sturdy frame (1) and having coaxially and independently housed inside it a toolhead spindle (7) which can be commanded to slide in axial direction with respect to said quill (4). A second chuckhead quill (20) is exactly contra-positioned with respect to the first (4) and is rotatably mounted to a support element (18) which is slidably mobile in a direction parallel to its axis and which is slidably commanded by a powerful coaxial hydraulic jack (23). A second toolhead spindle (21) is coaxially disposed inside said second quill (20) with freedom to slide axially with respect to said quill (20).
