Machine description
The basic design is based on a gantry moving along longitudinal guides.
The longitudinal movement (X axis) must be performed through the gantry by means of a toothed rack and two guides; one placed on each side of the bed
The gantry must consist of a guide bar of constant height and connecting the support for the two spindles.
