Machining with three to five axes

The TNC 128 is a compact but versatile straight-cut control for three servo axes and servo spindle. A further servo axis is an option.

For simple work, such as face milling, you need not write a program on the TNC 128. It is just as easy to operate the machine manually by pressing the axis keys or—for maximum sensitivity—using the electronic handwheel.


Conceived for both shop-floor and external programming.

Workshop-oriented programming is an important attribute of the TNC 128, particularly since the TNC controls are rooted in the workshop.

The proven HEIDENHAIN user interface is also the basis for the user-friendly programming, because the TNC 128 assists you during program creation with help graphics, practical prompts, machining cycles and cycles for coordinate transformation.

The TNC 128 can be programmed remotely just as well. Its Fast Ethernet interface guarantees very short transfer times, even of long programs.
