Work in Progress


Follows the scheme now become classic, we introduced in 1983 in the construction of machining centers, of a portal structure in which the movement of the axes X and Z are on the spindle while the Y axis is on the working plane. This form of construction allows to have a great dynamic stability combined with a considerable simplicity of construction.
