Mobile gantry CNC 4-axis machining centre, designed for drilling, milling, threading and cutting at any angle from -90° to +90° on bars or pieces in aluminium, light alloys in general and steel. The mobile part of the machine mainly consists of a gantry equipped with precision motorisation rack. The 9 kW electrospindle with HSK- 63F tool connection is able to perform even heavy-duty machining with excellent, rapid and accurate results. A fixed tool magazine with 14 places is installed on the left-hand side of the machine. It can be fitted with a second 14-place magazine on the other side of the machine or replaced by a single 14-place motorised magazine which, with its own NC axis, follows the mobile gantry in the two work areas, reducing the required number of tools and tool holders and considerably optimising programming. The machine can be used in double mode, a work method that reduces machine stop times to a minimum as it allows workpiece change time (loading/unloading) to be run "while the machine is operating". Furthermore, different workpieces can be machined between the two work areas. The machine is equipped with a cabin covering of the gantry that not only protects the operator, but also reduces the noise impact.

The machine can be optionally equipped with an electronic device that automatically corrects workpiece dimensional errors in length, width and height. In this way, the accuracy of the machine is not influenced by the differences between theoretic and actual workpiece dimensions during machining. This device accurately probes the rough workpiece in several positions, correcting the machining along its whole length, even with deformed or warped profiles.
