Pivoting, traversing, lifting, rotating – these are typical functions that are the order of the day in the construction of fixtures and installations and they are used, for example, to: – swivel-in a welding gripper – raise a complete subassembly to working level – traverse a clamp in order to remove components. In the majority of cases, straightforward cylinder or traversing axes do not satisfy the requirement in terms of reproducibility and accuracy of control. Inevitably, in practice it is necessary to resort to special designs, consisting of drive mechanisms, linear control, shock absorbers and switches, which are frequently newly-designed for each particular application. We claim that we are able to provide you with precise customised solutions – robust, compact, complete and, in addition, tried and tested with car production. With a view to offering a robust configuration for volume production, all the products described in this catalogue feature enclosed housings, heavy-duty bearings, guides and defined end position settings with fixed limit stops, mechanical locking and position sensing.

EK Electric clamp Clamp with toggle-lever mechanism, with electric motor instead of pneumatic cylinder. Encapsulated housing, connection compatible with the pneumatic series. A trapezoidal threaded spindle instead of a piston rod operates the mechanics driving the clamp arm. Integrated toggle mechanism, self-locking. Drive 24V DC.
he EDH+ series of small to heavy-duty rotary tables from EXPERT-TÜNKERS offers a powerful solution for flexible movement tasks in automation. Unlike traditional rotary tables with fixed indexing positions, the EDH+ series features a freely programmable servo drive, allowing for flexible and precise positioning. This enables individual adjustment of angles, speeds, and movement sequences – making it ideal for applications with frequently changing production requirements. Thanks to proven index cam technology, robust bearings, and a stable housing, the EDH+ series achieves the same precision as conventional drives – with a significantly more compact design. The particularly flat construction saves space and enables ergonomic fixture solutions.
NIMAK UniversalGUN The universalGUN is the next generation of welding guns and combines over 60 years of experience in resistance welding in a consistently modular concept. Thanks to its intelligent design with a significantly reduced number of parts, it is a powerful and future-proof alternative to classic robot welding guns. The universalGUN impresses with its rigidity, low weight and optimum accessibility – ideal for modern, highly dynamic robotic welding applications. Thanks to its high rigidity and low deflection, the universalGUN is ideally suited for welding applications involving high-strength sheet metal and hot formers with Al-Si coatings.
