TKE 743

3-axis CNC vertical machining center featured with a clamping system made up of vacuum tables that allow panels and plates to be held by vacuum; this solution is useful to obtain an extremely efficient machining of thin components that could hardly be fixed by means of a traditional clamping system. The machining center is equipped with a series of valves that turn on/off different areas of the machining table, thus concentrating the suction on one area and optimizing the clamping of components with limited dimensions. It is designed for drilling and interpolated milling operations on composite panels, panels and plates in aluminum and steel. To create programs that control the machines, Tekna provides user-friendly software tools that can be used both by professional CNC programmers, who can implement the most complex solutions, and by completely inexperienced users; after a few training hours the customer will be able to operate the machining center using a graphical programming. Software solutions offered by Tekna result from an accurate design and from the actual customer needs analysis. The simplicity of usage of these solutions reduces the management time and costs. The machine is equipped with Fanuc CNC Numerical Control, motors and encoders.

Electrospindle
10 kW S1 high torque electrospindle allows heavy duty machining. It can be used both with some types of extruded steel and with aluminium profiles, thanks to the lubrication system with oil emulsion spray mist or, as an option, with minimal diffusion oil.

TKE 743 Vacuum table Tekna
Vacuum table
The panels are clamped in position by a vacuum table. The plastic table is laid over and fixed to the aluminium cross members and provides efficient suction over the entire surface area, while providing protection against the ingress of lubricating liquid. The table is divided into extruded aluminium beams that are switched on/off individually by a valve system, activating the vacuum and locking only the areas where the panels to be clamped are positioned.
Tool magazine
Fixed 12-place tool magazine on board the machine. A mechanically moved mobile cover protects the tools from swarf and dust produced during machining.

TKE 743 Swarf removal system Tekna
Swarf removal system
The machining unit has a built-in suction system connected to an industrial extractor. This system effectively removes the machining dust, maintaining the extraction holes free and ensuring high-performance locking. It also makes machine cleaning operations between one load and the next much easier, eliminating much of the swarf that would compromise the correct clamping of the panel to the surface.
Software
The CN6 numeric control management software monitors all the machining centre functions by means of a graphic interface. It includes an ISO language editor and allows viewing the complete workpieces of the set machining operations in 3D. The functions can be extended with the optional NC Tool software, the CAD/CAM system that generates ISO programmes compatible with CN6, which can be combined with the Nesting software to optimise the figures to machine on the panels.
