4-axis CNC machining centre designed for working bars or parts in aluminium, PVC, light alloys in general and steel up to 2 mm. The machine can operate in single-piece and multi-piece mode, with a single work area for bars up to 7 m in length. The COMET X6 HP version allows working in pendular mode, with two independent work areas and 2 supplementary axes to position the vices and the reference stops; it allows operation in dynamic pendular mode, carrying out vice positioning in concurrent operation time. Each model has a 10-place tool magazine, on the X axis gantry, with the possibility of hosting an angle machining head and a milling disc, to perform machining on the 5 sides of the workpiece. The 4th NC axis allows the electrospindle to rotate from 0° to 180° and position itself at any intermediate angle. The machine can therefore perform machining operations on the top and side faces of the profile at any angle within the range. It also has a mobile work table that facilitates the workpiece loading/unloading operation and significantly increases the workable section.
