Servo presses in tie rod design are driven directly by torque motors. They deliver high torque values and are the right drive for dynamic forming processes. The lack of a flywheel and clutch / brake combination makes the presses flexible, energy efficient and reduces the maintenance required.
The pendular stroke mode is exceedingly energy efficient and permits operator-programmable slide strokes without any additional mechanical stroke adjustment. In addition, the pendular mode results in significantly higher stroke rates. Thanks to the operator-programmable time / travel motion sequences as well as the ability to provide rest times for in-die functions, processes such as welding and lasering can be integrated reliably into the press cycle.
