Despite this, TNC 150, TNC 151 and TNC 155 users can of course still rely on HEIDENHAIN, even after 30 years, to provide solutions when servicing is needed—machines equipped with the control classics can be upgraded to the latest controls. Such modernizations are particularly advantageous with machines having large traverse ranges and mechanically robust constructions, and customers specify the latest control model for upgrading purposes according to their machine and desired extent of modernization. The TNC 128 or TNC 320 are available for simple 3-axis machines, whereas upgrading to the state-of-the-art TNC 640 control is recommended for machines that are more complex.
The result is a sustainable modernization of machines and production processes, achieving production with greater precision and efficiency. The new HEIDENHAIN controls feature modern hardware with faster processors, significantly larger memories for NC programs and modern, rapid graphic simulation. NC programs are imported via USB stick as standard, and connecting to the company network via Ethernet is just as possible. 2-D drawings can be loaded directly on the control with the DXF import option, and contours or positions for boring and drilling operations are simply clicked on, thereby saving time and avoiding errors during the importing process. Also decisive for many customers is the full upward compatibility of TNC controls—thanks to this, operators can largely continue to use the old NC programs on a control from the TNC 150 range on modern controls. Users rapidly familiarize themselves with the new control thanks to the intelligent user interface, and only new cycles need to be learned, if used.
