TKE 954 TEKNA
4-axis CNC mobile gantry machining centre, designed for drilling, milling and threading at any angle from -90° to +90° on bars or pieces in aluminium, PVC, light alloys and steel up to 2 mm thickness. The mobile part of the machine is composed of a gantry with double gantry motorisation on a high precision rack The local safety cab, made in technopolymer, was designed to combine top functionality, accessibility, soundproofing and light with safety and ergonomic requirements. The operator has broad glazed surfaces to check machining execution and easy access during cleaning and maintenance. Cab interior ensures chip conveying to the collection system available in the base. The 8.5 kW electrospindle is able to perform even heavy-duty machining with excellent, rapid and accurate results. The 12-place tool magazine, integrated into the mobile gantry, features two dedicated positions for holding a blade with a maximum diameter of 250 mm and an angular machining head. 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 m long; the second one, in double operation, for working on multiple workpieces in the two separate working areas. In version with clamp handling system on H and P axes, the machine can be used in dynamic double operation, a work method that enables reducing machine stop times to a minimum, as it enables automatic arranging of the clamps in concurrent operation time with respect to the spindle machining processes in the opposite working field. TKE 954 features a laser scanner for more precise and advanced access control to the machine, raising safety and operator/machine interface standards. In double operation, the laser scanner, unlike the light curtains, allows, from time to time, the appropriate programming of the two separate working areas on the X-axis, increasing the flexibility of use of the machine.
Tool magazine
A spacious toolholder magazine with 12 places is installed on board the mobile gantry. The housing includes a tilting system that ensures maximum protection of the toolholder cones from both swarfs and accidental impacts. The magazine has two specific positions to accommodate angle machining head or disc cutter without reducing the total capacity. The position of the magazine on board the gantry allows tool change times to be minimised and dynamic double operation machining to be managed,
Vices and dynamic tandem
The vice unit can ensure the correct and safe clamping of large aluminium, steel and light alloy profiles. The vice structure, in particular the wide Y stroke, allows the machining of large profiles, thus meeting the typical requirements of industrial and door applications. Each vice unit can be configured with double hold-down device for the machining of two parallel profiles. In the HP version, vice positioning is managed by additional CNC axes. In dynamic double operation mode, the CNC simultaneously manages the movement of the vices and of the mobile gantry in the two separate work areas, thus allows significant increases in productivity.
Full protection cabin
The local guarding cabin has been designed to offer optimal functionality, accessibility and lighting while fulfilling safety and ergonomics requirements. The innovative and refined design makes the machine unique and unmistakeable. Large glass windows allow the operator to monitor the machining operations being executed and a large access to internal areas is provided for cleaning and maintenance operations. The internal structure optimises the conveying of swarf and scraps to the lower side, simplifying the maintenance and cleaning phases on all delicate parts.
Electric head (high-power and high-torque spindle)
The electrospindle - 8.5 kW in S1 - with HSK-63F toolholder and water cooling with chiller unit, can also perform the heavy-duty machining typical of the industrial sector. Moreover, the high torque ensures easy drilling, milling and cutting operations. The electrospindle movement along B axis performs -90° to +90° rotation, allowing to work on 3 sides of the profile with no need to reposition it. A 10 kW electrospindle with encoder for heavy-duty machining is available as optional.
Laser scanner
The protection of the operator is entrusted to a monitoring system of the work area with laser scanner. This intelligent control system, together with the absence of fixed references at the centre of the machine, is specially useful in double operation mode, since it allows managing the two work areas with a variable set-up, even asymmetrical. The laser scanner will adapt the controlled surface to the size of each zone, allowing workpieces of different lengths to be machined and taking advantage of the available work area without special structural limitations.
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.
