TKE553

home / materials / Aluminum

Twin-head cutting-off machine with 3 axes controlled by automatic movement of the mobile head and electronic management of all 45° (internal) to 15° (external) angles, with a precision, within each degree, of 280 positions. Advancement is driven by a pair of hydro-pneumatic cylinders. The innovative virtual rotation axis of the cutting units, subject of one of the patents that accompany this machine, as well as conferring absolute rigidity to the system, allows to manage positioning and profile blocking with great accuracy. These features allow to obtain a greater cutting precision than any other machine in its category. All axes movements take place on guides and slides on ball bearings. The automatic protections of the heads, the design of the push button control panels, front access to the electric and pneumatic panel, make it an advanced model also from a safety and ergonomics point of view.

Head protections

Automatic local head protections, made of scratch-resistant polycarbonate, are operated by a pneumatic cylinder with an anti-crushing device that resets the pneumatic load to zero when closing. They are mounted on a laterally sliding system to better shelter the operator in any cutting operation.

Load and unload

The cutting-off machine is equipped with a roller conveyor on a mobile head for standard loading and unloading procedures. The roller conveyor can be optionally fitted with an extra vice to immobilise the residual profile and an electronic machined profile thickness meter for automatic cutting positions correction in accordance with the real profile dimensions, with the associated surface treatments tolerance.

Cutting units inclination virtual axis

Tilting of each head, up to 15° outward and 45° inward for both aluminium and PVC versions, is done by means of two circular guides placed on four pairs of steel casters. This patented solution makes it possible to eliminate obstructions in the cutting area, all to the benefit of profile positioning and clamping, while also offering greater rigidity than traditional systems. The absolute magnetic strip positioning system dispenses with the need for axes homing procedures, with the associated idle times.

Profile clamping

Making use of the ample space provided by the use of the virtual axis, clamping of the profile to be cut is performed by two horizontal hold-down devices with extreme precision and in absolute safely. For vertical clamping, particularly for special cuts, the machine can be equipped with a patented system of horizontal hold-down devices.

Control

The ergonomic state-of-the-art control panel features a 10.4” touchscreen display and fully customised software and is packed with functions developed in the Microsoft Windows® environment specifically for this machine. The machining cycle can be optimised by creating cutting lists, thereby reducing scrap and cycle times for parts loading-unloading.

Label printer

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.
