    摘要： A machine tool includes a rotation device, a tool holder, and a power feeder. The rotation device includes a rotation body rotatable about a first axis. The tool holder is attachable to the rotation body. The power feeder is configured to supply power to the tool holder. The tool holder includes a power receiver, at least one sensor, a power feeding part, and a first mover. The power receiver is provided in an outer circumferential edge region of the tool holder. The at least one sensor is electrically connected to the power receiver. The power feeder includes a power feeding part and a first mover. The power feeding part is configured to supply the power to the power receiver. The first mover is configured to move the power feeding part between a power feeding position facing the power receiver and a retracted position spaced further apart from the power receiver than the power feeding position is apart from the power receiver.

    摘要： A machining module that can be mounted on a tool turret of a numerically controlled lathe is described, with a slotting tool that performs a forward stroke, in which it is engaged with a piece, and a return stroke, in which it is disengaged from the piece, with a drive shaft that can be connected to a power take-off of the turret, with a planetary gear that transforms a rotational motion of the drive shaft into an alternating rectilinear motion of a pin, with a slide guided by the pin to perform forward and return strokes, with a shuttle guided to slide back and forth on the slide in a coordinated manner with the motion of the slide, with a tool holder that slides on the slide in a transversal direction to the motion of the slide and with a guide mechanism that transforms the sliding of the shuttle into a sliding of the tool holder which disengages the slotting tool from the piece at the end of the forward stroke and engages it again at the end of the return stroke.

    摘要： The present invention relates to an Operative device (11) for a machine tool (1) which is suitable for machining at least one piece (P) and provided with an electrospindle unit (10), said operative device (11) comprising: an inlet shaft (14) which is rotatable about a first rotation axis (A1) and connectable, in use, with said electrospindle unit (10) such that said inlet shaft (14) is rotated, in use, by said electrospindle unit (10) about said first rotation axis (A1); a first toothed wheel (15) being conical and a second toothed wheel (16) being conical, which are coaxially coupled to said inlet shaft (14); a first outlet shaft (17) which is rotatable about a second rotation axis (A2) being substantially orthogonal to said first rotation axis (A1) of said inlet shaft (14), wherein said first outlet shaft (17) is connectable, in use, with a first tool (U1); a third toothed wheel (18), conical, which is coaxially coupled to said first outlet shaft (17) and engaged with said first toothed wheel (15) such that, in use, said first toothed wheel (15) rotating about said first rotation axis (A1) of said inlet shaft (14) causes said third toothed wheel (18) to rotate about said second rotation axis (A2) of said first outlet shaft (17) based on a first gear ratio of the rotary motion; a second outlet shaft (20) which is rotatable about a third rotation axis (A3) being substantially orthogonal to said first rotation axis (A1) of said inlet shaft (14), wherein said second outlet shaft (20) is connectable, in use, with a second tool (U2), and wherein said third rotation axis (A3) of said second outlet shaft (20) and said second rotation axis (A2) of said first outlet shaft (17) are substantially coplanar; a fourth toothed wheel (21), conical, which is coaxially mounted to said second outlet shaft (20) and engaged with said second toothed wheel (16) such that, in use, said second toothed wheel (16) rotating about said first rotation axis (A1) of said inlet shaft (14) causes said fourth toothed wheel (21) to rotate about said third rotation axis (A3) of said second outlet shaft (20) based on a second gear ratio of the rotary motion which is different from said first gear ratio of the rotary motion; and a supporting and containing structure (12) which supports said inlet shaft (14), said first outlet shaft (17) and said second outlet shaft (20) and contains said first toothed wheel (15), said second toothed wheel (16), said third toothed wheel (18) and said fourth toothed wheel (21).

    摘要： Machining centre, particularly for beams or the like, which includes:
    - a gantry beam having a passage opening for a beam to be machined;
    - feeding means for a beam to be machined, according to a straight feeding path of said beam that is oriented according to a first translation and insertion axis (X) of the beam through said passage opening;
    - a working unit comprising an electrospindle for coupling and driving the at least one working tool, said working unit being supported by means for moving said working unit according to at least one axis, or optionally two, three, four or five axes of movement, and wherein said at least one tool changing station comprising a tool magazine is provided, wherein said working unit is movable in said at least one tool changing station, with the electrospindle in a position of loading and/or unloading a tool in said tool magazine by means of automatic devices for coupling to a tool and/or uncoupling and unloading a tool. According to the invention, as a working tool which can be coupled and uncoupled to the electrospindle there is provided an intermediate tool-holder head having an input shaft which can be coupled to said output of the electrospindle and at least one output shaft provided with a coupling spindle of a further working tool, said output shaft being oriented with its axis perpendicular to the axis of the input shaft.
