A torsionally-rigid portal (9) is fixed to the machine bed (2), having a gantry (11) between two lateral uprights (10). The spindle mounting (20) is adjustable along the gantry on a first axis (-Y). The bed protrudes in front of the portal to one side. The uprights can be at the opposite sides of the bed, and can be supported from its protruding end. A closed stiffening rear wall (13) can be mounted between the uprights, and can also be rigidly secured to the bed. |
