What is a servo press?

A servo press is a high-precision electromechanical system that offers a superior alternative to traditional pneumatic or hydraulic solutions. It is a key component integrated into an automation machine to perform assembly, crimping, stamping or forming operations with a high cycle rate.

How it works

Imagine a smart cylinder driven by an electronically controlled motor. Unlike a pneumatic cylinder, which exerts a variable force, the servo press converts electrical energy into mechanical motion via a servo motor and a ball or roller screw. It is equipped with sensors that continuously measure the position and the force applied, enabling closed-loop control of both the position and the force applied.

The benefits

  • Quality and reduced scrap: The servo press controls force and position in real time with sub-micron resolution. Each part is assembled identically, eliminating variations that cause scrap. The system immediately detects a non-conforming part and stops the cycle.
  • Energy savings: Unlike pneumatic systems, which consume energy continuously (compressors running even when the machine is stationary), the servo press only consumes energy during movement.
  • Industrial data capture: Each operation generates a force/displacement curve that can be stored, analysed and exported. This allows the quality of each part produced to be tracked, trends to be identified and processes to be continuously optimised.
  • Reduced maintenance: Fewer components than a pneumatic system (no more leaking cylinders, no more compressors, no more filters).
  • Less noise: No more compressed air hissing. A servo press operates silently (68–73 dB depending on the model)

Customer benefits

  • Superior quality, less waste
  • Reduced operating costs
  • Smart production (data-driven)
  • Low noise and reduced maintenance
  • Scalability / Flexibility
  • Same skills required for both online and workstation integration

MecaMotion

MecaMotionis the programming and control platform developed by Softeca for its electric servo-press systems. It is the software ‘brain’ that transforms an electric cylinder into a smart, precise assembly system that is fully integrated into an automated production environment.

MecaMotion

In practical terms, when you purchase a servo-press solution from Softeca, the basic kit always includes a licence for MecaMotion, making it a central component.

Simple and Intuitive Programming

MecaMotion aims to make the programming of servo-press processes accessible. Instead of writing complex lines of code, the operator uses a range of graphical functions to build their cycle. They can thus combine actions such as:

  • Axis positioning.
  • Basic arithmetic operations for simple
  • calculations.
  • Wait times.
  • Conditional jumps within the programme.
  • Signal measurement and recording of force/position curves
  • … and much more

Quality Control via ‘Envelope’

This is one of MecaMotion’s most powerful features. To ensure that every assembled part is correct, the software uses a control envelope system.

Practical Applications

Thanks to its flexibility, MecaMotion can control the servo press for a wide range of assembly and testing operations:

  • Assembly: Crimping, riveting, clipping, insertion, bonding, marking.
  • Forming: Bending, deep drawing, punching.
  • Testing: Stiffness tests, spring tests, tensile tests.
  • Inspection: Force and position measurement.
