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.
