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.

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 to be worked and is rotatable about its own axis;
- a first carriage, which supports a turret tool post for supporting a plurality of selectively usable tools;
- and
- a second carriage, which supports a rotatable driven gear hobbing tool head;
- said first and second carriages being movable on command along respective horizontal and vertical axes, by means of a controller unit, with respect to said main mandrel in order to selectively move the tools installed on said turret tool post and the hobbing tools so that they machine the part supported by said main mandrel, said first and second carriages being respectively arranged at opposite sides with respect to the mechanical part to be worked, to work both sides of the mechanical part at the same time.
