5-axis CNC machining centre used for the working of bars or aluminium, PVC, light alloys in general and steel pieces. It is provided with two operating modes: a single work area for bars up to 7 m length or two independent work areas in swing 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 swing mode. The 4th and 5th axis allow the electric spindle to continuously rotate to NC from -15° to 90° on horizontal axis and from 0° to 720° on continuous vertical axis, to perform the work on the upper side and on all the lateral sides of the profile. It is provided with a 12-place tools magazine, on the X axis gantry, able to host also one milling disc. It also has a mobile work surface that facilitates the piece loading/unloading operation and significantly increases the workable section.
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 pieces; additionally, the ends feature aluminium guards that act as a support plane if needed.
Clamp 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- piece mode with one profile for every pair of clamps.Furthermore, the positioning of the clamps takes place independently of the operational condition of the spindle (X-axis).
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.
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 B and C axes allows working on 5 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.
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 in the workshop. The outlet for the chip conveyor belt and its motor are built into the lower section, in view of an aesthetic and functional design.
Comet R has two operation modes: a single work area for bars up to 7 m long, or two independent work areas in pendular mode. The HP version machine has 2 additional axes for positioning clamps and reference stops, enabling the clamps to be positioned in masked time during pendular mode operation.
The innovative machining mode allows reducing machine stop times during loading and unloading of the pieces to be worked. The system allows, in the two distinct and independent working 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.
