Particularly time-intensive tasks such as adjusting the material feed, positioning the slide units and adjusting the movements of the forming punch are now completed in a matter of minutes on the VC 1 machine and process control system. The servo-controlled processing units guarantee a consistently high product quality. All processing units are freely programmable over the whole working range. Working stroke, lower dead centre, adjustment of the stroke position and the motion profile can be selected freely.

button on the integrated slide positioning unit. Rapid tool change systems help to further reduce set-up times. The RM-NC is impressive also in terms of productivity. Up to 300 manufactured parts per minute speaks for itself. Costs for new tools are reduced considerably by the small number of components while existing tools in the RM series can easily be integrated. The servo-controlled machine is able to replace several mechanical machines and allows users a much higher creation of value. Compared to conventional stamping and forming machines, an output increased by up to 200 per cent can be achieved, lot sizes can be processed in half the time and changeover times reduced by a factor of nine.

With the RM-NC Bihler presents an entirely new generation of stamping and forming machines. The completely servo-controlled machine is perfectly designed for the economical production of stamping and forming parts as well as wire parts in all lot sizes. The RM-NC shows its benefits especially for small and medium lot sizes and for a large number of different product versions. Very short, 100 per cent reproducible set-up and changeover operations are its key strengths. These are ensured by modern servo technology in combination with the intuitive control technology of the Bihler VariControl VC 1. For instance, the slide units can be aligned in radial and linear direction simply by pressing a

Forming movements can be executed with constant transmission of force.
