A milling machine for machining on wood beams, which comprises a guided movement line (11) for a beam (12) to be machined and a milling station (13) which comprises two milling assemblies (18, 19) which are controlled by electronic means (20) and are each adapted to mill mutually opposite faces (12a, 12b, 12c, 12d) of the same portion of beam (12). The milling assemblies (18, 19) each comprise a single cutter (23, 30) which is associated with respective means (21) for translational motion along two respective perpendicular directions which lie on a plane which is arranged transversely with respect to the direction of the movement line (11). The electronic means (20) coordinating the translational motion means (21) in order to allow simultaneously the cutters (23, 30), arranged at the beginning of the milling sequence on corresponding contiguous faces (12a, 12b, 12c, 12d) of the beam (12), a first stroke for milling along a respective face (12b, 12c), a second idle stroke along a face (12c, 12d) which is contiguous to the previously milled one, and a third stroke for milling along the face (12d, 12a) which is parallel to the previously milled one; the cutters (23, 30) are moved around the beam (12) along a same direction of motion.
