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 GRM-NC shows its benefits especially for small and medium lot sizes and if you require a large number of different product versions. Very short, 100% 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 button on the integrated slide positioning unit. Rapid tool change systems help to further reduce set-up times. The GRM-NC allows users to react to customer requirements very quickly and demand-oriented.
240 parts per minute – nine times faster set-up
The GRM-NC is impressive also in terms of productivity. Up to 240 manufactured parts per minute speak for themselves. Costs for new tools are reduced considerably by the small number of components. Existing tools of the GRM series can be easily integrated and optimized on the GRM-NC. Then the servo-controlled machine is able replace several mechanical machines and allows users a much higher creation of value. Compared to conventional stamping and forming machines, an output increased by more than 200% can be achieved, lot sizes can be processed in half the time and changeover times reduced by a factor of 9. Formerly 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.
Consistently high product quality and process safety
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 center, adjustment of the stroke position and the motion profile can be selected freely. The maximum force can be achieved at any time and at any stroke position. Forming movements can be executed with constant transmission of force. The result: Strip and wire material is processed with optimal speed at each station. For maximum process safety, all units have an integrated cooling and central lubrication system. Other features include a software-based integrated overload protection as well as an absolute measuring system for full compensation of process-related temperature effects.
Intelligent control technology
The Bihler VariControl VC 1 machine and process control system ensures a comfortable and reliable operation. Changeover procedures are completed by the press of a button on the customized menu and are 100% reproducible. All machine functions as well as the number of axes and axis movements are configured without external programming devices directly on the controller. The bASSIST multimedia diagnostic and online help system supports operators with videos, graphics, etc. (including customized items) and allows to easily optimize processes.
