Abstract: Described herein is a nNumeric-control machine (1) comprising: a flatbed (2) provided with a horizontal working surface (3), on which a workpiece (4) is to be positioned; a machining head (5) which is able to move in space above the working surface (3), and a supporting structure (6), which is designed to support and displace the machining head (5) in space above the working surface (3), the supporting structure (6) consisting of: a floating platform (7) mounted so that it can move above the working surface (3), a series of articulated supporting arms (8) designed to support the floating platform (7) above the working surface (3) on opposite sides of the platform itself, and members for moving (13, 14) capable of displacing upon command and independently the articulated arms (8), each articulated arm (8) being designed to connect the flatbed (2) of the machine with the overlying floating platform (7).

Abstract: A worktable for numerical control machines, having a supporting structure hinged to the frame of the machine tool, and a faceplate fitted for rotation to the supporting structure to rotate, on command, about a first reference axis; the worktable having a first drive unit specially designed, on command, to rotate, and maintain rotation of, the faceplate at high speed about the first axis, and a second drive unit specially designed to vary, as required, the angular position of the faceplate about the first axis and with respect to a predetermined angular reference.

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.
