(57) A machining centre for machining workpieces (1) made of wood or the like comprises:
a worktable (3) supporting the workpiece (1) and equipped with at least one holding
part (4) positioned at the side of the worktable (3) and designed to clamp the workpiece
(1) and, respectively, to move it in a direction of feed coinciding with a first axis
(X) towards a frame (6), extending transversally to the worktable (3), and supporting
a machining head (7) slidably movable along a second axis (Y) transversal to the worktable
(3) and along a third, vertical axis (Z); a holding table (10) is inserted between
the machining head (7) and the workpiece (1), movable with the machining head (7)
along the second, transversal axis (Y); the table (10) slidably associated with a
first supporting guide (11), positioned on the frame (6) and extending parallel with
the second, transversal axis (Y); means (12) for adjusting the table (10) along the
third, vertical axis (Z), positioned on the first guide (11) and acting on the table
(10) in such a way as to position the table (10) relative to the workpiece (1) and
irrespective of the position which the machining head (7) can assume along the third,
vertical axis (Z).
