Machine tool for machining semi-finished aluminum or titanium alloy products

A machine tool suitable to machine semi-finished aluminum alloy or titanium alloy products and designed to rest on a horizontal reference plane, for example a ground plane, said machine tool comprising:

• a supporting structure comprising a bench having a main extension along a longitudinal direction, and a rear support extending both along the longitudinal direction and along a vertical direction, wherein the bench and the rear support are rigidly connected to each other, and wherein the supporting structure is provided with upright translation means oriented according to the longitudinal direction;
• an upright connected to the supporting structure by the upright translation means so as to translate along the longitudinal direction, said upright comprising carriage translation means oriented according to the vertical direction;
• a carriage connected to the upright by the carriage translation means so as to be translatable along the vertical direction;
• and
• a working head engaged with the carriage and having a tool holder seat suitable to house a tool for chip removal machining,
• wherein the machine tool further comprises a first pair of carriage moving ratio motors and a second pair of carriage moving ratio motors, and wherein said first and second pairs of carriage moving ratio motors are positioned aboard the upright and engaged to the carriage translation means.
