Benefit from our expertise and experience in all manufacturing-related areas.
Take advantage of our wide range of state-of-the-art manufacturing processes.
Our portal milling machines, such as the DMU 210 μPrecision and 125 μPrecision, enable micrometer-level tolerances with three times the precision of standard machines. With 5-axis simultaneous machining, reference-controlled temperature control, and a volumetric accuracy of less than 20 μm, we set standards in precision manufacturing. Thanks to the positioning accuracy of up to 4 µm and generous travel ranges of up to 2,100 × 2,100 × 1,250 mm (82.7 × 82.7 × 48.2 in), we guarantee maximum precision and stability—even for the most demanding applications.
We use state-of-the-art laser marking systems to individually mark your components—from company logos to data matrix codes. Whether rotationally symmetrical or cubic, we guarantee precise and durable results according to your specifications.
Integrating grinding technology into our mill-turn processes ensures excellent surface quality and dimensional accuracy. By machining in a single setup, we achieve the highest process security and stability.
Our specialized CAM team combines many years of experience with the latest software to implement your design data efficiently and precisely. This is how we consistently achieve complex workpiece shapes and master challenging machining tasks with the highest level of quality.
Our wire EDM machines produce intricate contours regardless of material hardness. With wire diameters from 0.05 mm (0.002 in) and precise travel paths, we guarantee dimensional accuracy and quality.
Our specialized manufacturing processes are tailored to the high standards of the semiconductor industry and guarantee maximum precision and quality.
You can rely on state-of-the-art measuring technology and precise testing procedures to ensure the highest quality standards in production. Our air-conditioned measuring rooms are equipped with state-of-the-art equipment for comprehensive quality inspections:
Our specialized cleaning processes ensure particle- and residue-free components for contamination-free manufacturing.
Customized packaging solutions according to industry-leading standards ensure optimum protection and safe transport.
