Abstract: The machine tool (1) having a work head (9) adapted to support a tool (21), a workpiece holder (30) having a two substantially parallel beams (31) arranged at a distance adjustable orthogonally to the longitudinal extension of the beams, a carriage (35) on each beam (31) movable along the longitudinal extension of the beam (31), on each carriage (35) a suction cup (39) for blocking the workpieces (P) to be machined. The position of each suction cup (39) with respect to the carriage (35) onto which the cup is mounted is adjustable by rotating around an axis (D-D) which is substantially orthogonal to a blocking surface, for blocking the workpieces, defined by the suction cups (39). To each suction cup (39) an actuator (46, 48) is associated, controlling the rotation of the suction cup (39) with respect to the carriage (35) onto which the cup is mounted.

Abstract: A numerically controlled turning center (1; 100), includes a support and rotation unit (19) having a first pair of support and rotation members (21, 23) aligned with each other along a first rotation axis (A1) and a second pair of support and rotation members (25, 27) aligned with each other along a second rotation axis (A2) parallel first rotation axis (A1). There is also provided a machining head (13) with a rotary tool (13.1) movable along a first numerically controlled translation axis (X) parallel to the rotation axes (A1, A2) of the first pair of support and rotation members and of the second pair of support and rotation members. The machining head (13, 15, 17) and the support and rotation unit (19) are movable one with respect to the other in a direction (Z) orthogonal to the first rotation axis (A1) of the first pair of support and rotation members (21, 23) and to the second rotation axis (A2) of the second pair of support and rotation members (25, 27).
