Energy-saving servo press with precise control
Servo presses are ideal for creating different joints, for example by press fitting, caulking, riveting, stamping, clinching, and much more, thanks to their control options and variable stroke lengths.
Depending on the model, the press force of IAI servo presses ranges from 24 N to 50 kN, with a stroke length between 100 mm and 500 mm. Almost all of them can be ordered in stroke length increments of 50 mm.
The TÜV-certified safety monitoring functions of the SCON2 controller enables servo presses to be operated without a protective fence or emergency shutdown of the drive source. The functional safety unit monitors ongoing operation and safely shuts down the servo-electric press in case of danger.
Servo-electric presses from IAI are used in automatic production systems as well as in manually controlled workstations. Typical applications are in the automotive sector as well as in the production of medical and electronic products and in the household appliance industry.
Cost-effective RCP6 servo press
The new RCP6 servo press can perform both push and pull movements in the load direction. It is equipped with a 24 V stepper motor and a load cell for force control. This has a load repeatability of ±1.0% of the sensor's maximum capacity (full scale).
Thanks to the stepper motor, the servo press costs over 50% less than comparable models with a servo motor that deliver the same press force. In addition, operation is significantly simpler. The press or tensile force is set using percentage values.
There are no restrictions on the pushing or pulling times. The product range includes three models with pushing forces ranging from 60 N to 2,000 N.

RCS3 servo spindle presses are characterized by their precise positioning control, simple thrust force adjustment, and accurate position monitoring. They ensure high holding stability during press assembly and are therefore ideal for thrust operations.
The thrust force adjustment and position monitoring are based on the feedback data from the built-in load cell. It records the force acting on the press object and enables precise force control with a repeat accuracy of ± 0.5% of the full scale (FS) deviation.
The IA-OS software (PC Software) includes eight different press assembly programs for RCS3 and RCS2 servo presses, which can be used for a wide range of press movements. You can choose between the control modes “speed control” or “force control.”
In addition, a hold method can be selected from the four stop conditions “Position,” “Travel,” “Load,” or “Incremental Load.”
The TÜV-certified safety monitoring functions of the new SCON2 controller enable the use of RCS3 and RCS2 servo presses without protective fencing or emergency shutdown. When people approach, the servo press is safely stopped without interrupting production.
In addition, all SCON controllers have interfaces to fieldbus networks. The target position, speed, acceleration, etc. are entered into the controller via corresponding position numbers and then specified externally for axis operation via input/output signals.

Servo presses are increasingly replacing conventional hydraulic or pneumatic presses. The technological decision is usually based on the better energy balance, precise controllability, and greater flexibility.
1. Precision and repeatability
- Servo drives enable very precise force and position control.
- Typical repeatabilities are in the range of ±0.01 mm or better.
- Ideal for applications with high quality requirements (e.g., in electronics, automotive, or medical technology).
2. Process monitoring and documentation
- Servo presses measure force and displacement in real time.
- The entire joining process can be recorded, analyzed, and documented.
- This enables 100% process monitoring and traceability.
3. Energy efficiency
- Energy is only consumed during the joining process.
- No pumps or compressed air generation as with hydraulic/pneumatic systems.
- This results in significantly lower energy consumption and operating costs.
4. Cleanliness and low maintenance
- No oil, no leaks, no hoses – the system is clean and environmentally friendly.
- Maintenance requirements are significantly lower than for hydraulic systems.
5. Flexibility
- Force, displacement, and speed profiles are freely programmable.
- One system can perform several different joining tasks.
- Ideal for flexible manufacturing and frequent product changes.
6. Low noise and compact
- Significantly quieter operation without a hydraulic unit.
- Compact design, as no separate unit or tank is required.
