Machine tool for machining semi-finished aluminium alloy 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, 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, wherein the upright translation means comprise a first pair of upright translation members fixed to the bench and a second pair of upright translation members fixed to the rear support;
• 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 carrying a tool holder seat suitable to house a tool for chip removal machining,
• wherein the machine tool further comprises four pairs of gearmotors positioned aboard the upright and engaged with the upright translation means, wherein a first pair of gearmotors and a second pair of gearmotors of said four pairs of gearmotors engage the first pair of upright translation members, and wherein a third pair of gearmotors and a fourth pair of gearmotors of said four pairs of gearmotors engage the second pair of upright translation members.
