NEW TNC 640 Control Introduced for Milling and Turning Machines

Just introduced at the EMO 2011 show in Germany is the TNC 640 control, the first milling-machine control by HEIDENHAIN offered with optional turning functions. With this control, HEIDENHAIN is expanding its selection of high performance controls into the complete-machining market.

Suited for high speed cutting and for 5-axis machining on machines with up to 18 axes, the HEIDENHAIN TNC 640 control can now easily enable turning operations on a milling machine. The turning operations can be programmed in plain text, just like the familiar milling operations. Comprehensive turning cycles are available for frequently repeated operations, such as roughing, finishing recessing and thread cutting.

The TNC 640 is based on a new and completely digital interface hardware platform called HSCI. This interface significantly reduces cabling during setup. This control’s new optimized user interface also gives users greater transparency during programming, presents functions better and displays status information more clearly. The new smartSelect function makes it easier, for example, to select cycles, and syntax color highlighting improves clarity for the editing of machining programs.

HEIDENHAIN’s TNC 640 also boasts a new ergonomic design with a 19” screen, and an operating panel with stainless steel fronts.
