Abstract
A numerical-control milling machine having a supporting frame; a worktable fitted to the supporting frame so as to oscillate about a substantially horizontal first axis of rotation, and in turn having two rotary platforms, each for accommodating a workpiece; and two independent work units, each of which is fitted movably to the supporting frame, alongside the worktable, is positioned facing a corresponding platform, and provides for machining the workpiece on the platform; the two work units selectively operating either asynchronously, to machine the workpieces fixed to the two platforms independently of each other, or synchronously to perform the same machining operations simultaneously on the workpieces fixed to the two platforms.
Claims16
A numerical-control milling machine (1), comprising:
- a supporting frame (2), and a worktable (3) which is fitted to the supporting frame (2) so as to oscillate about a substantially horizontal first axis of rotation (A) and comprises at least two platforms (4) which are aligned side-by-side along the first axis of rotation, each for accommodating a workpiece;
- the milling machine (1) further comprising two independent work units (5), each of which is positioned facing a respective platform (4) of the worktable (3) with a toolspindle which is capable of rotating about a second axis of rotation (B) lying in a plane (P′) substantially perpendicular to said first axis of rotation (A), each of said second axes being parallel to one another, the toolspindles movable in space along three cartesian axes (X, Y, Z) for machining the workpiece on the respective platform (4);
- the first axis of rotation (A) of the worktable (3) being parallel to a first axis (X) of said three cartesian axes (X, Y, Z);
- the toolspindles of the two work units (5) being movable in space along the three cartesian axes (X, Y, Z) fully independently one to the other and the milling machine (1) also comprising actuating means for governing the movement in space of the toolspindle of each of the two work units (5) so as to automatically machine two separate workpieces, each fixed to one of said respective platforms (4), and a central control unit (35) for controlling said actuating means so as to machine the two workpieces on the worktable (3) either synchronously by moving the two toolspindles in space synchronously one with each other, or asynchronously by moving the two toolspindles in space fully independently of one to the other.
A numerical-control milling machine (1), comprising:
- a supporting frame (2), and two worktables (3) which are aligned side by side along a horizontal first axis of rotation (A) and are fitted to the supporting frame (2) so as to oscillate about said first axis of rotation (A);
- each of said two worktables (3) comprising a respective platform (4) for accommodating a workpiece;
- the milling machine (1) further comprising two independent work units (5), each of which is positioned facing one of said respective platforms (4) and is provided with a toolspindle which is movable in space along three cartesian axes (X, Y, Z) for machining the workpiece on the respective platform (4);
- the first axis of rotation (A) of the two worktables (3) being parallel to a first axis (X) of said three cartesian axes (X, Y, Z);
- the toolspindles of said two work units (5) being movable in space along the three cartesian axes (X, Y, Z) fully independently one to the other and the milling machine (1) also comprising actuating means fat governing the movement in space of the toolspindle of each of the two work units (5) so as to automatically machine two separate workpieces, each fixed to one of said respective platforms (4), and a central control unit (35) for controlling said actuating means so as to machine the two workpieces on the two worktables (3) either synchronously by moving the two toolspindles in space synchronously one with each other, or asynchronously by moving the two toolspindles in space fully independently one to the other;
- each of said two work units (5) further comprising an upright (8) mounted to slide on the supporting frame (2) in a direction parallel to said first axis of rotation (A), a toolhead (10) mounted to slide vertically on the body of the upright (8), and a motor-driven spindle (11) fitted to the toolhead (10) with its toolspindle facing said worktable (3);
- each of said toolspindles being positioned horizontally and being capable of rotating about a second axis of rotation (B) lying in a plane (P′) substantially perpendicular to said first axis of rotation (A).
