A machine presenting a worktable (8) movable along a first axis (Y); and a crosspiece (11) fitted with a number of machining heads (12) and movable along a second axis (X) perpendicular to the first axis (Y). The crosspiece (11) presents a box structure, and two end portions (32) guided on two horizontal appendixes (34) of two fixed uprights (36). Between one of the appendixes (34) and the corresponding end portion (32) of the crosspiece (11), there is provided a screw-nut screw pair (52, 53) for selectively moving the crosspiece (11). Each machining head (12) is assigned a tool store (56) accessible from the rear of the machine. <IMAGE> |
