Compact Inverters Optimize Machining Performance
In addition to a wider screen that allows for a split view, Gen 3 drives for Heidenhain’s TNC 640 control system allow for jig grinding and trochoidal milling capabilities on smaller machine tools.

Compact Gen 3 drives for Heidenhain Corp.’s (Schaumburg, IL) TNC 640 control provide even higher spindle and axis dynamics on operations ranging from 3-axis milling to 5-axis simultaneous machining with milling, turning and grinding operations with up to 24 axes. They also take up less space in the electrical cabinet, reducing storage needs, mounting costs and servicing time.
In addition to Dynamic Precision functions that significantly improve contouring accuracy at high feed rates, capabilities include jig grinding, enhanced viewing, and optimized contour milling (OCM).
TNC 640 now supports jig grinding and dressing of grinding tools. It can also superimpose the tool axis with an optional reciprocating stroke, which is necessary for many grinding applications.
A 24-inch-wide screen provides enough space for a divided view, allowing users to display additional applications alongside the control screen. Integration of HTML5 applications as well as capabilities for displaying cameras in the work envelope have been added.
OCM expands trochoidal milling capabilities within Dynamic Efficiency to any pocket shape and island. It allows for the use of high cutting values without overloading the tool and can be programmed directly on the control. OCM machines workpieces up to three times faster and with two-thirds less tool wear than conventional machining.
Heidenhain’s StateMonitor 1.3 makes it very easy to remotely monitor efficiency improvements of these CNC functions.
