When every micron counts.
Turned parts for hydraulic and pneumatic components. Tight tolerances, consistent surface finish, high pressure resistance.
Präzision ist der Kern unseres Handwerks.
Application
Precision parts for hydraulic and pneumatic applications – with the surface finish that keeps things sealed.
Hydraulic systems forgive no errors on mating surfaces. Our turned parts are manufactured with consistent surface finish – reproducible, every batch the same.
We work with a range of materials from stainless steel to brass and manufacture both series and spare parts in small quantities.
Typical parts: piston rods, valve housings, connection fittings, nozzles, spool housings.
Frequently asked questions
What Hydraulics buyers often ask.
What surface finishes do you achieve on sealing surfaces?+
Standard directly from the turning process is Ra 0.8. For demanding sealing functions, Ra 0.4 reproducibly. Mirror finish only with downstream polishing or grinding.
Can you apply hardness levels to piston rods?+
We coordinate external hardening – induction, case hardening or quenching and tempering – through established partners. Hardness profile documentation included.
Which materials are typical in hydraulics?+
Quenched and tempered steel 42CrMo4 for mechanically loaded parts, stainless steel 1.4305 or 1.4571 for corrosive media, brass CuZn39Pb3 for connection fittings and nozzles, bronze CuSn8 for plain bearings.
How tight are fit tolerances for hydraulic components?+
H7/g6 for sliding fits, H7/h6 for transition fits, H7/k6 or H7/p6 for press fits – we implement the ISO fit system.
Do you offer pressure testing of finished parts?+
We coordinate external pressure and leak testing when required. For simple parts, often integrated into the first article inspection report.
Can you also manufacture spare parts in small quantities?+
Yes. Hydraulic spare parts are a typical application. Lots from quantity 1, calculated transparently.
