Servo-hydraulic control for CNC press brakes


Product characteristics

The patented electro-hydraulic drive ePrAX® modular is tailored to the special requirements of drives for CNC press brakes. All requiredcomponents are composable based on a modular concept and allow an optimal use of the mounting space through a flexible arrange-ment.

For each actuator a servo motor takes over the control of power stroke and fast stroke as well as bending force. The return strokepartly takes place using temporarily stored hydraulic energy. In this way a high dynamic with significant energy savings and shorter cy-cle periods is possible. At the same time the operating noise of the press brake is drastically reduced by each adapted speed.

The hydraulic system with its optimized oil circulation system leads to a very high system stiffness and thus to a high control accuracy.The pre-finished and fully tested press drive involves only minimal installation and maintenance effort. A standardized cylinder inter-face allows different cylinder sizes and therefore variable lifting speeds. Further options, such as modules for tool clamping, are avail-able for the press drive.

The ePrAX® modular complies with valid accident prevention regulations and is certified with proof of concept number 18003.
