Servo press are designed to support a wide range of joining processes


Unlike other brands of servo press, the IEF Werner aiPRESS from RARUK Automation features a torsion-resistant steel, C-frame with precise ram guidance that absorbs all the transverse forces. This ensures the drive chain remains rigid throughout the cycle to eliminate positioning errors.

As a result, the aiPRESS has become known Europe-wide for its accurate and repeatable processing and is widely specified as a stand-alone machine for precision pressing, joining, sizing, deep-drawing, fastening, calibrating, bending, clinching, embossing, stamping, straightening and riveting.

Now this concept has been further developed to provide systems’ designers and machine builders with a highly flexible servo press module that can be integrated into manual workstations and automatic assembly lines.

These new aiPRESS JM modules are available in the UK from RARUK Automation in three sizes with press forces of 3kN, 15kN and 36kN and strokes of 75mm, 125mm and 175mm respectively. Maximum speed is 150mm per second and repeat accuracy, <0.002mm.

Although the stroke of each model is fixed, where it starts and stops is fully controllable and can therefore be adjusted to suit the application. The module can also be installed in any orientation, for example vertically, inverted or horizontally and combined with turntables or sliding tables. A choice of mounting components is available to provide this flexibility.

Integration into any machine control system is easily achieved via standard protocols or the module can also be specified with IEF Werner’s proven aiQ-CONTROL. This is an intelligent force path monitor which measures position and force and illustrates the pressing process graphically and monitors its course.

Another option is aiLIGHT intelligent process area lighting which supports set-up and operation by changing from white to blue and green to signify the process step. A red light alerts the operator to a failure.

The aiPRESS JM modules are especially suited to fully automated handling and assembly lines, for example, as a precision pressing or joining station in an IEF Werner posyART transport system; also available from RARUK Automation. They are also a good choice for the manual workplace for processing specific components.

Industries that will benefit from this introduction are electronics, medical device, automotive and aerospace production where precise positioning and force measurement verification is required, often with data logging and quality assurance traceability.

The RARUK Automation website now carries a link to a dedicated microsite for the aiPRESS. The site guides visitors th

rough the features that make these servo presses different and includes typical applications and videos demonstrating their easy set-up.
