Precision Parts Manufacturerfrom Germany for the world
FERNAU has manufactured high-precision turned and milled parts since 1995 for mechanical engineering, medical devices, aerospace, metrology and energy systems. Customers in Germany, Europe, the UK, the USA and Asia rely on our tolerance discipline and delivery reliability.
Why source precision parts from Germany
Precision is not a marketing claim, it is measurable. At FERNAU typical tolerances are ±5 µm, surface roughness Ra 0.4 µm without secondary grinding. We document, we measure, we deliver. And if something does not fit, we say so openly in the quotation, not at shipping.
