4-axis CNC machining centre designed for working bars or parts in aluminium, PVC, light alloys in general and steel. It includes two different operating modes: the first one, in single-zone mode, for machining whole bars in a single working area, up to 7.0 m long; the second one, in double operation, for machining multiple workpieces in the two separate working areas. All CNC axes are absolute and do not require resetting upon restarting the machine. The machine in HP version features 2 additional axes that, in double operation, allow positioning in the clamps and reference stops in concurrent operation time with respect to the spindle machining processes in the opposite working field. The 4th axis allows the electrospindle to rotate to CNC from –120° to +120° on horizontal axis, to machine the top and the side faces of the profile. Features a 12-place tool magazine, on the gantry (X-axis), with two suitable positions for holding a blade with a maximum diameter of 250 mm and an angular machining head. The mobile worktable facilitates the workpiece loading/unloading operation fully ergonomically, and significantly increases the machinable section on the Y-axis.

4 axes electric head -S-
The 8.5 kW electrospindle in S1 with high torque also enables performing the heavy machining typical of the industrial sector. A 10.5 kW electrospindle with encoder for rigid tapping is available as optional. Electrospindle rotation along A axis allows working on 3 sides of the profile, with no need of repositioning. Normally used for machining extruded aluminium profiles, it also enables machining steel profiles thanks to the twin tank lubrication system: one with minimal oil diffusion, and the other with oil emulsion spray.

Dynamic double operation
The innovative machining mode allows minimising downtimes when loading and unloading the workpieces to be machined. The system allows, in the two distinct and independent work areas, to simultaneously carry out the loading/unloading of extruded profiles on one side, and machining of workpieces on the other, with different lengths and/or codes. This solution makes the machine very flexible, which is highly suitable for the field of window/door frames and for small work orders, where machining is required for small lots of different pieces.
HP version
Comet has two operation modes: a single work area for bars up to 7 m long, or two independent work areas in double operation mode. The machine in HP version is equipped with 2 additional axes for positioning of vices and reference stops, that allow positioning the vices while the machine is working in double mode.
Products for Aluminium Comet S6 HP Vice positioner Emmegi
Vice positioner
Vice unit positioning is performed by two numerically controlled axes, H and P, parallel to the X-axis, with on-board reference stop. This solution allows positioning stops all along the machine to work in multi-workpiece mode with one profile for every pair of vices. Furthermore, the positioning of the vices takes place independently of the operational condition of the spindle (X-axis).
Glass protection
Safe, perfect, resistant, long-lasting. These are the advantages of choosing glass for protecting the new Comet machining centres. Glass is also easy to clean and less susceptible to scratches and wear. Machine cuts operate to flag machine statuses, thanks to a light colour interface. The whole visor slides downwards, thus making it easier to load the workpieces; additionally, the ends feature aluminium guards that act as a support plane if needed.
Operator interface
The possibility of rotating the monitor on its vertical axis allows the operator to view the screen from any position. The user interface has a 24” touchscreen display in 16:9 format, portrait mode, equipped with the necessary USB connections for PC and CNC remote interfaces. It also features an operator panel, mouse, and it is set up for connecting barcode reader and remote operator panel.
Tool magazine

The tool magazine is integrated on the X axis, in the lower part and behind the electrospindle. It allows great reduction of tool change times. This function is particularly useful in the extrusion head and tail machining, avoiding the stroke to get to the magazine, as it moves simultaneously with the electrospindle and its positions. The magazine can contain up to 12 tool holders with relevant tools, which can be set at the operator’s discretion. Each position of the tool holder is provided with a sensor detecting the correct cone position.

Foldaway tunnel (Optional)
Integrated with the machine’s aesthetics and design, thanks to the perforated sheet metal for transparency and lightness, the tunnel opens and closes as needed. As its length can be reduced when not in use, it helps save space at the workshop. The outlet for the chip conveyor belt and its engine are built into the lower section, in view of an aesthetic and functional design.
Label printer (Optional)

The industrial label printer allows each cut profile to be identified with identifying features from the cutting list. In addition, barcode printing enables easy identification of the profile itself, which is particularly useful for subsequent machining steps on Machining Centres or assisted assembly lines.
