What is a Servo Press?
A servo press is a machine that uses a servo motor to precisely control the movement of a ram. Servo presses are used for joining, pressing, fastening, and riveting workpieces. They can be used in automatic production plants or manually controlled workstations.

These systems are widely applied in the automotive industry for assembling New Energy Vehicles (NEV), engines, transmissions, steering systems, chassis, brakes, injection pumps, and airbags, as well as electric motors like windshield wiper motors. They are also extensively used in sectors such as medical devices, electronics, domestic appliances, and power tools.
A servo press joining system typically includes a joining module (or "joining spindle"), a servo amplifier, and a force-displacement evaluation unit. Quality assurance is ensured through process monitoring systems, which use data from force and displacement sensors to evaluate and document force-displacement profiles (XY curves) during joining and press-fit processes.
These systems not only monitor the process but can also control it in real-time. Standard functions include force cutoff and control, gradient and inflection point detection, and signal or position-based joining.
Servo presses or electromechanical joining systems are increasingly replacing conventional hydraulic or pneumohydraulic systems due to their superior energy efficiency, precise control, flexibility, and lower total cost of ownership (TCO).
How a Servo Press Works
- Servo Motor: Converts electrical energy into mechanical motion, controlling the press's speed, position, and torque.
- Control System: Manages the servo motor's movements, programs complex motion profiles, and enables real-time adjustments.
- Feedback Sensors: Monitor the ram's position, speed, and force, sending data to the control system for continuous adjustments.
Key advantages include:
- Energy Efficiency: Contribute to climate protection with a significantly better energy balance, reducing CO2 emissions by up to 90% compared to traditional technologies.
- Enhanced Quality: Ensure and improve product quality through real-time process monitoring during manufacturing.
- Increased Productivity: Reduce scrap, leading to lower operating costs and higher plant productivity.
Advantages of a Servo Electric Press
- High Accuracy: The positional feedback system ensures precise operation with fine adjustments, ideal for processes requiring tight tolerances or expensive materials.
- Repeatability: Maintains consistent operation even with changing loads, adjusting controls for reliable, repeatable performance.
- Exceptional Control: The closed-loop system offers precise control over speed and position, suitable for both delicate and high-power applications.
- High Power: Delivers substantial force while maintaining accuracy and control, adaptable for both delicate and tough materials.
- Quiet Operation: Operates with minimal noise, reducing the need for hearing protection for operators.
- Speed: Capable of rapid operation up to 300mm/s, maintaining efficiency without compromising quality.
Disadvantages of Servo Electric Presses
- High Cost: Advanced performance features result in higher initial costs compared to other press types, including hydraulic options.
- Complexity: Expensive components and intricate construction lead to costly maintenance, often requiring factory repairs.
- High Voltage: Operates at 240V or 480V, increasing safety risks compared to lower-voltage systems like pneumatic presses.
Where Are Servo Presses/Electromechanical Joining Systems Used?
Servo presses excel in applications requiring extreme precision and accuracy, such as medical device or aerospace manufacturing, where tight tolerances are critical. Beyond assembly, servo actuators are integral to controlling various products like robots, drones, and other electronics. With their precise closed-loop feedback systems, they are also employed in vehicles to control functions such as steering motion or the speed of aircraft, submarines, and automobiles.

Is a Servo Press Right for You?
Choosing the right press for your application requires careful consideration. If your process demands high accuracy, precision, and smooth operation, a servo press could be an excellent choice. However, many complex processes can also be accomplished using a force and distance monitoring air-over-oil press at a fraction of the cost. Additionally, pneumatic, hydropneumatic, and hydraulic options may provide the required capabilities with a better return on investment.
