component manufacturing
In component manufacturing, riemann combines precision, flexibility and material control. Functional parts, interface components and structural components are produced in automated milling cells with repeatability of up to ± 0.01 mm. Complex geometries are implemented efficiently, regardless of whether they are individual pieces or small series.
Large-format processing for heavy and long workpieces with high stability over long travel distances. The portal design is particularly suitable for massive structural components.

Powerful 5-axis machining center for high-volume components and high cutting performance. Our reliable platform for precise processing in continuous operation.

Powerful precision for medium-sized components with high requirements. Thanks to DuoBlock technology, stable, exactly reproducible results are achieved.

Melting wire electrode/Inert gas guided arc/Durable bonded connections
Highly focused light beam/Precise thermal processing/Welding, cutting, structuring
Short-term high-current pulses/Almost invisible welding spots/ Joining processes for painted surfaces
Mechanical cold joining/Multi-layer sheets/Without heat or additives
Thermally formed flow hole/Self-cutting thread/High-strength sheet metal connections
Heavy-duty punching riveting process/ High-strength steel grades/ Thick material combinations
The riemann promise
Standstill is not an option: We provide tools and components on an expedited basis – with express manufacturing, spare parts expertise, and maintenance.

Measuring, testing, documenting – by using high-end 3D measurement technology and recognized standards. We stand for certified quality – even for safety-critical components.

Re-engineering, technical optimization, development-oriented implementation. Our expertise in tooling, materials, and processes is incorporated into every solution.


from an 18-ton block to high-precision optics
From an 18-ton aluminum block, riemann manufactured a high-precision component for an optical application in the semiconductor industry. The aluminum used: high-purity, low-tension, of exceptional dimensions – a material that requires special material expertise and process-reliable processing. In a very short time, we reduced the raw part to 3.8 tons. More than 14 tons were machined in a controlled manner – with enormous volumes but uncompromising precision. Dimensional accuracy and surface quality in the µ-range, zero errors, no rework. Fewer than five providers worldwide are implementing such projects. We're part of it.
