4-axis CNC machining centre with moving gantry structure. Designed for drilling, milling, thread cutting and cutting at angle any from 0° to 180° on bars or workpieces of aluminium, PVC, light alloys in general and steel. The moving part of the machine consists of a gantry with precision rack and pinion drive. The high power 7,5 kW electrically-driven spindle with HSK-63F tool holder allows machining operations, including heavy-duty work, with optimum results in terms of speed and accuracy. A 9-place tool magazine is installed behind the moving gantry structure. The machine can be used in double mode so as to minimize machine downtime, as it is possible to change the workpiece (load/unload) and the automatic setting of the vices in “concealed” time. It is also possible to load and consequently machine different workpieces and to perform different machining operations between the two work areas. The gantry is provided with a guard which, besides protecting the operator, also reduces the noise impact on the environment.

The tool magazine is large and quick and is installed directly on the machine's carriage. Its lateral position, together with an exclusive housing, guarantees maximum protection of the toolholder cones from swarfs and accidental knocks. The magazine can contain up to 9 (8 + 250 mm blade) toolholders with relevant tools, which can be set at the operator’s discretion. Each position of the toolholder is provided with a sensor detecting the correct toolholder cone position.
By exploiting the wide Y work area, the machine can be equipped to position, refer and clamp two profiles in parallel in the vices, working both profiles in a single cycle and thus allowing a very significant reduction in the machining time. Performing drilling and milling machining in the inner faces using angle machining head requires feasibility check.
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.
