Abstract: A CNC machining centre is disclosed, with an additive unit that forms an unmachined workpiece by additive production and that comprises an operating member with a rotation axis, and with a subtractive unit that removes material from the unmachined workpiece formed by the additive unit and that comprises a tool-holding spindle with a motorized spindle axis, with a subtractive configuration, in which the spindle axis of the subtractive unit carries a tool for removing material, and with an additive configuration, in which the spindle axis of the subtractive unit is connected to the rotation axis to drive the operating member of the additive unit and in which a prevalent part of the tool-holding spindle is situated next to at least one part of the operating member, where “next to” means in a horizontal direction.

Abstract: A machining centre comprising a machining plane; a subtractive unit for performing chip removal on a workpiece positioned on the machining plane; the subtractive unit comprising a first carriage that is slidable parallel to an operating axis; an additive unit arranged to perform machining by additive production techniques on the machining plane; the additive unit comprising a second carriage that is slidable along the operating axis. The additive unit is provided with a first coupling portion and said subtractive unit is provided with a second coupling portion couplable with the first coupling portion. In one step, the subtractive unit adopts a pick-up configuration in which the first coupling portion is coupled with the second coupling portion to connect the subtractive unit to the additive unit at least along the operating axis. In the pick-up configuration, the subtractive unit, connected to the additive unit, is configured to move the additive unit.

Abstract: A system for supporting a workpiece is disclosed, wherein several heads with a suction cup define an engaging and supporting surface that is at least partially shaped like the workpiece. Each head with suction cup is coupled by a ball joint with a first movable element of a vertical linear actuator and is couplable by a removable fitting with a fork carried by a second movable element that rotates around a rotation axis that is coaxial with the axis of the linear actuator. The second movable element carries an abutment, spaced from the center of the ball joint against which the suction cup head abuts and moved by the linear actuator to perform the adjustment of the orientation thereof around the ball joint.
