TKE  551 Tekna Double head cutting machine

The 551 model is positioned as “entry level” , although guaranteeing innovation and advanced performance. It is simpli ed but only where necessary, all for the bene t of pricing/competitiveness in the market. The inclination of each head, up to 22°30’ outwards, takes place via two circular guides positioned on four pairs of steel rollers. This solution, subject to patent, allows you to eliminate any cutting area obstruction, with the advantage of positioning and blocking the pro le and offers greater rigidity to traditional systems. Positioning via absolute magnetic band eliminates the necessity of the axes reference and connected cycle times.

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

Inclination of each head, up to 22°30' outwards for both the aluminium and PVC machine versions, is achieved on two circular guides mounted on four pairs of steel rollers. 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. X axis absolute magnetic strip positioning eliminates the need for the axes reference and connected cycle 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. Three mechanically operated intermediate supports deploy automatically to support the profile for very long cutting lengths.

Control

The intuitively designed control panel allows correct mobile heads positioning in accordance with the required cutting schedule. The interface uses a 5.7” touch-screen and fully personalised software and is packed with bespoke functions that are unique to this machine. The control panel can be optionally installed on bearings sliding on a rail that spans the entire front of the machine. The machining cycle can be optimised by creating cutting lists, thereby reducing scrap and cycle times for parts loading-unloading.

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.
