Clamping systems
Precise workpiece clamping made to measure.
- Efficient and accurate centering < 0.01 mm
- Optimally adapted to difficult geometries and processes
- Guarantees the greatest possible tool freedom
- Smartly controlled and monitored
Workpiece clamping is the starting point for a successful machining process.
With stable lightweight construction, precise fine balancing and high process reliability, we guarantee sustainable, resource-efficient operation. This applies both to the machining process and to operator safety – naturally in compliance with the EC Machinery Directive 2006/42/EC.
We design, develop and manufacture our special clamping systems tailored to the individual geometry of your workpiece and the requirements of your machining process.

Highest quality thanks to strict controls.
We offer you high-end quality because our systems undergo two tests during manufacture and before delivery:
- Measurement of each relevant individual part before assembly: checking dimensional accuracy, shape and position tolerances.
- Extensive endurance tests on our test bench after assembly.
Development partner from concept to commissioning.
Whether it’s a new machine, a retrofit, or the modification of existing machine tools, STERMAN supports projects from the initial idea and design through engineering, manufacturing, and assembly to commissioning—and, upon request, well beyond that. With a value-added ratio of over 85 percent, our solutions are primarily manufactured at our facility in St. Georgen in the Black Forest. For an initial clamping concept, a workpiece drawing and the essential information about the machining process are usually sufficient.
“We inventors from the Black Forest have always had a high technological influence on progress within many industries – worldwide. Our high level of specialization is a guarantee for both technical challenges and sustainable business – and therefore future security.”
