Our European production facilities are located in southern Germany (Lauchheim) and in the Czech Republic (Jihlava).

We are also proud to make reference to our European Design & Engineering Center (E-DEC) based in Lauchheim. We created 2,000 square meters of presentation, training, and meeting rooms to present theory-based trainings and practical machinery presentations. Latest technologies enable demonstrations of tools and systems in action. Work pieces can be machined, the production processes can be optimized and together the acquired expertise can be evaluated and confirmed directly on the machines in the presentation center. Our customers receive the complete solution, which they can subsequently transfer to their own production.
