Multi-operation machine tool control
IMTS 2012: Heidenhain's TNC 640 control is designed for machine tools capable of multi-operation machining.
The TNC 640 control by Heidenhain is suited for HSC and 5-axis machining on machines with up to 18 axes. Equipped with the familiar TNC milling functions and the turning functions, the TNC 640 is a powerful control for multi-operation machining.
The hardware of the TNC 640 is based on a new and completely digital hardware platform. All components are connected to each other through digital interfaces. The uniformly digital design is the optimum precondition for combining highest accuracy and surface definition with high traversing speeds.
The TNC 640 also features powerful processor hardware. The block processing time is just 0.5 ms, and a hard disk with up to 138 GB for use by the operator is available for NC programs.
Along with the milling cycles the TNC 640 offers many turning cycles for:
- Longitudinal turning
- Transverse turning
- Contour recessing
- Thread cutting
