Link Mechanical vs. Servo Press

Learn More about Our Products


Link motion mechanical presses and servo presses are two distinct types of machines used in metal forming processes. Link motion presses operate based on a mechanical linkage system, while servo presses utilize advanced servo motor technology. Let’s explore the key differences between these two press types.

Motion Control
Link Motion Mechanical Press
  • Operates with a fixed stroke length determined by the mechanical linkage. The motion is generally less flexible and adjustable.
Servo Press
  • Employs a servo motor for precise control over the slide motion. This allows for dynamic adjustments, providing flexibility in stroke length, speed, and dwell time.

Precision and Accuracy
Link Motion Mechanical Press
  • Offers good precision but may have limitations in achieving high accuracy due to the mechanical linkage.
Servo Press
  • Excels in precision and accuracy, as the servo motor allows for fine-tuned control, making it suitable for intricate forming processes.



Speed and Versatility
Link Motion Mechanical Press
  • Speed changes are often achieved by adjusting the mechanical linkage, which may take more time. Limited versatility in terms of speed variations.
Servo Press
  • Rapid and seamless speed adjustments are possible with servo technology, making it versatile for a wide range of forming operations.

Energy Efficiency
Link Motion Mechanical Press
  • Generally consumes more energy, especially during idle times, as the mechanical linkage may continue to operate.
Servo Press
  • Offers improved energy efficiency as the servo motor operates on-demand, reducing energy consumption during idle periods.

Setup and Changeover
Link Motion Mechanical Press
  • Changeovers may involve manual adjustments to the mechanical linkage, potentially leading to longer setup times.
Servo Press
  • Faster and more automated setup/changeover processes due to programmable servo controls, enhancing overall production efficiency.

Maintenance and Wear
Link Motion Mechanical Press
  • The mechanical linkage may experience wear over time, requiring regular maintenance and potential downtime.
Servo Press
  • Generally experiences less wear, resulting in reduced maintenance needs and increased overall machine reliability.

In conclusion, the choice between a link motion mechanical press and a servo press depends on the specific requirements of the metal forming application. Link motion presses are reliable for certain applications, while servo presses offer advanced features, precision, and efficiency, making them suitable for a broader range of modern manufacturing needs.
