Contouring Control for Milling and Milling/Turning Machines

Besides milling, the TNC 640 from HEIDENHAIN is also capable of combined milling and turning operations. It is particularly well suited for milling-turning, HSC and 5-axis machining on machines with up to 24 axes. The workshop oriented and versatile control features numerous functions. It is especially attractive for the following areas of application:

Universal milling machines
Combined milling-turning machines
High speed milling
Five-axis machining with swivel head and rotary table
Five-axis machining on very large machines
Boring mills
Machining centers and automated machining

The optimized user interface of the TNC 640 gives you a fast overview: various color coding, standardized table editors and smartSelect—the dialog-guided fast selection of functions—aid you at your work.

The TNC 640 features optimized motion control, short block processing times and special control strategies. Together with its uniform digital design and its integrated digital drive control including inverters, it enables you to reach very high machining speeds and the best possible contour accuracy—particularly when machining 3-D contours.

You can program turning contours with the TNC 640 in the familiar HEIDENHAIN plain language. Beyond this, you have typical contour elements for turning (recesses, undercuts, thread undercuts) as well as cycles for complex turning operations.
