Machine tool with an assembly configuration with a cantilevered tool

A machine tool for carrying out operations on a part, the machine tool comprising:

• a longitudinal rail configured to be positioned relative to the part;
• a transverse arm orthogonal to the longitudinal rail, the transverse arm comprising two ends;
• a module for connection between the transverse arm and the longitudinal rail, the connection module being fitted in translation on the longitudinal rail;
• a tool supported by the transverse arm;
• at least one retention unit arranged at one end of the transverse arm, and comprising at least one sucker permitting retention in position of the retention unit on the part,
• wherein the transverse arm comprises means for securing on the connection module, positioned between the two ends of the transverse arm, such that the machine tool has an assembly configuration in which the retention unit and the tool are positioned respectively on both sides of the longitudinal rail, such that the tool is fitted cantilevered relative to the longitudinal rail, and
• wherein the transverse arm further comprises means for securing on the connection module, positioned at the end of the transverse arm opposite that where the retention unit is arranged, such that the machine tool has an assembly configuration in which the tool is supported by the transverse arm between the longitudinal rail and the retention unit.
