Abstract: A multifunction modular machine tool for integrated machining processes permits the combination of a number of units which can machine a workpiece to be machined (P) in a coordinated manner with one another, with a single hold, without therefore requiring any relocation of the workpiece, and comprises a main headstock (30) capable of disposing a workpiece to be machined (P) inside a workspace (A) and to effect a rotation (CC1) thereof about a main axis (ZZ1) during different machining operations, and at least one work guide (42) which extends in a direction substantially parallel to the main axis (ZZ1) and supports at least two work units (10, 11, 21, 21?, 22, 23, 23?, 24, 25, 26, 26?) which are able to slide independently on the work unit guide (42) in such a way that they can be disposed, alternately and independently of one another, inside said workspace (A), in such a way as to operate on the workpiece to be machined (P), or outside said workspace (A).

Abstract: A numeric-control machine tool for turning and hobbing mechanical parts, comprising: a main mandrel, which is provided with grip means for a mechanical part and can be rotated about its own axis; a first carriage, which supports a turret tool post for turning and/or milling and/or drilling; and a second carriage, which supports a gear hobbing tool head. The first and second carriages can move on command, in a controlled manner, with respect to the main mandrel in order to selectively move the tools installed on the turret tool post and the hobbing tools so that they machine the part supported by the main mandrel.
