Comet R6 HP

home / product a to z / C

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 -360° to +360° 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.

5 axes electric head -R-

8.5 kW S1 high torque electrospindle also allows heavy duty machining, which is typical in industrial processing. As an option and for higher performances a 11 kW encoder equipped electrospindle is available for rigid tapping. Electrospindle rotation along B and C axes allows working on 5 sides of the profile, with no need of repositioning. It can be used for some types of steel extrusions as well as for aluminium profiles, thanks to the software-adjusted lubricating system. With its double tank it allows either minimum oil circulation or oil emulsion spray-mist.

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.

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).

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 toolholders with relevant tools, including a blade with a maximum diameter of 250 mm, 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.
