TNC 640

Heidenhain

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.
