Frequently Asked Questions (FAQ)
What are CNC components used for?
CNC components are used in applications requiring high precision, tight tolerances, and reliable performance, such as automotive systems, hydraulics, and mechanical engineering.
Which materials are used for CNC components?
We process high-quality engineering steel, including:
- Quenched and tempered steels (e.g. for shafts and piston rods)
- Case-hardening steels (e.g. for shafts and piston rods)
- Bearing steels (for running and guide surfaces)
- Spring steels
The specific material selection is application-specific and coordinated with our sales team. Common standards include DIN, EN, ASTM, or customer-specific specifications.
What tolerances can be achieved in CNC machining?
Depending on the material, geometry, and heat treatment, we manufacture components up to tolerance class ISO h6. For high-precision applications such as hydraulic components or guide shafts, we also use grinding and polishing processes. The achievable surface finish and dimensional accuracy are clarified on a project-specific basis using your drawing.
Do you produce prototypes and small series?
Yes. Thanks to our machinery, we can economically manufacture individual parts and prototypes as well as medium and large series. Programming is CAD/CAM-supported, which allows for short setup times even for small quantities.
For series applications in the automotive sector, we work in accordance with IATF 16949 using IATF-compliant approval processes.
Which surface finishes are available?
Available surface finishes include:
- Hard chrome plating – for piston rods, hydraulic cylinders, wear-resistant surfaces
- Zinc-nickel coatings – for corrosion protection in automotive applications
- Zinc flake coatings – for tribologically stressed components
- Special coatings according to customer specifications
Which certifications does Stahl Judenburg have for CNC manufacturing?
Stahl Judenburg is certified according to:
- IATF 16949:2016 (Automotive quality standard)
- ISO 14001:2015 (Environmental management)
The IATF 16949 certification confirms our process capability for safety-relevant automotive components. The scope includes the manufacture of profile steel, rolled and bright bar steel, hard chrome-plated piston rods, and machined components.
