Reconfigurable machining center

A reconfigurable machining center (1, 100), comprising:

• a first base structure (2), which extends longitudinally in a first direction (X);
• a first movable crossmember (3), which is supported on the base structure (2) so as to be movable with respect to the base structure (2) in the first direction (X) and is provided with a machining head (4),
• a first leadscrew rack (5), integral with the base structure (2) and comprising a first helical circular toothed sector (51), the first leadscrew rack (5) extending along the base structure (2) in a longitudinal direction parallel to the first direction (X) for an entire extension of the base structure in the first direction (X);
• and
• a first screw (6) rotatably coupled to the first movable crossmember (3) by way of a moving assembly (7), said first screw (6) engaging the first leadscrew rack (5), the screw having a rotation axis parallel to the first direction (X),
• wherein the longitudinal extension of the base structure (2) in the first direction is an integer multiple of a pitch of teeth of the first leadscrew rack (5), and
• wherein the base structure (2) further comprises coupling elements (8) that are adapted to couple the base structure (2) to one or both of a following or preceding adjacent base structure (2′), along the first direction (X).
