RM-NC GRM-NC Servo stamping and forming machines

The world’s fastest servo stamping and forming machines Increase the efficiency in your production. With the servo stamping and forming machines RM-NC and GRM-NC you manufacture a wide spectrum of classical stamped and formed parts as well as wire parts more flexible and productive. Benefit from very fast tool changes, flexible handling of even smallest batch sizes as well as constantly high production quality. Full tool compatibility with machines in the RM and GRM series opens up unbeatable prospects regarding increase in output and shortest change-over times.

The highlights at a glance ■ Highly efficient production of stamped and formed parts as well as wire parts even in smallest batch sizes ■ High production speeds up to 300 1/min. ■ Rapid response to short-term customer requests ■ Convenient operation with VariControl VC 1 ■ Full tool compatibility with RM series ■ Decisive increase in output (more than 300% possible*) ■ Extremely short set-up times (up to 9 times faster*) Production tests: Moving tools from mechanical machine types to servo-controlled machine + optimization

RM-NC / GRM-NC At a glance Integrated overload protection for NC components Fully automatic alignment and positioning in radial and linear direction Freely programmable: Working stroke BDC Adjustable stroke position Motion profile Easy handling Integrated absolute travel measuring system Integrated press force and bearing temperature monitoring Freely programmable (friction press): Working stroke BDC Adjustable stroke position Motion profile No fixed stop on tools All interfaces available to RM and GRM series Up to 3-fold central dies Integrated slide alignment and positioning unit Radial...

RM-NC / GRM-NC Alignment and positioning unit Fast and reproducible positioning The RM-NC and GRM-NC have a fully automatic alignment and positioning unit in the machine corpus. It allows the positions of the NC slide modules to be adjusted radially and linearly simply by pressing a button. Once the slide positions have been set up they can be stored in the tool program. When the positions are retrieved or after a tool change, all positions are stored or can be restored for absolute reproducibility. Accurate assigning The alignment and positioning unit is capable of moving the NC slide...

RM-NC / GRM-NC Presses Servo two-point eccentric press RM-NC Servo friction press GRM-NC Nominal force 200 kN Fixed stroke with B.D.C. Integrated press force and bearing temperature monitoring Pre-tensioned press housing – Installation space for dies 368 mm x 202 mm x 126 mm (LxWxH) Nominal force 400 kN Freely programmable stroke and stroke position adjustment No B.D.C., maximum press force possible at any time Integrated press force and bearing temperature monitoring Installation space for dies 670 mm x 207 mm x ma

RM-NC / GRM-NC Slide units / feed / central mandrel Maximum processing freedom All processing units are NC-controlled and 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. Maximum output can be achieved at any time and with any stroke position. Forming motion can be implemented with constant power transmission. The compact radial gripper form feed RZV 2 impresses with high feed speeds and excellent positioning accuracy. Variable feed lengths from zero to infinity as well...

Tool compatibility with RM series and GRM series When the number of product variations rises and the size of batches drops, production with a servo system offers significant advantages over mechanically driven stamping and forming machines. Therefore the RM-NC and GRM-NC are fully compatible with tools in the RM and GRM series. All tools from these machines can be easily adapted and optimized for these servo systems. All interfaces for machine, press and processing units are given. The press disposes of a universal press plate for the integration of existing dies; slides dispose of...

Machine and process control Easy handling Highlights of the control system The central machine and process control unit VariControl VC 1 supports the operator like a second operator on the machine. The machine is operated via a swivel terminal with touchscreen and other operating elements. The switching cabinet and the actuator are fully integrated in the machine casing of the RM-NC/GRM-NC. Easy, flexible machine setup without external programming device Customized menu-driven entry for fast setup and retooling Multi-media diagnostics and online help system bASSIST Direct programming NC...
