Structure robustness and high stability of all components of this machining center allow the TK 427 / 428 model to be used not only to perform machining operations on light alloys and similar materials but also on materials that require higher performances (i.e. steel, iron, etc.). The peculiarities of the machine assure an excellent superficial finishing and a better machining accuracy. This machining center is designed for drilling and milling processes and also for copy-milling operations on aluminum extruded profiles and other materials, including steel profiles up to 10 mm thick, steel reinforced PVC, and various other plastics. Standard versions are available in 3 machining lengths: 3500, 6500 and 8000 mm. Upon request the machining centre can be manufactured in different lengths in order to meet the special needs of each customer.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.
