Stainless stepped tubes and shafts turned complete – multiple diameters in one bar-fed cycle. Each step is gauged; transition radii are turned, not sharp, so stress does not concentrate at the step under load.
Function and Design
The stepped tube is judged by the dimension nobody checks until a failure – fit, seal or concentricity. That is why the stepped tube is inspected between operations, not only at the end.
Key Features
- A stepped tube carries one job in the assembly, and every tolerance on it exists to protect that job. Any drift in the stepped tube process is corrected at the machine, not sorted out at inspection.
- Stainless construction means no coating to fail in washdown or humid conditions.
- Material certificates and dimensional reports are available on request.
- Material: For the stepped tube we default to stainless steel (304 / 316); the grade is locked before tooling starts.
- Process: CNC turning and milling for the stepped tube, bar-fed where the geometry allows, stepped diameters held across operations.
- Finish: Natural, plated or coated to drawing – the stepped tube finish is approved in writing before production.
- Size: Stepped tube size to drawing, with the agreed version governing every later batch.
- Custom: Custom stepped tube production – samples and first articles precede volume.
Where It Is Used
In service you will find this part in automation and robotics hardware, instrumentation fittings, electronic and telecom enclosures.
Factory-Direct Advantage
Bar-fed cells run unattended for consistency, and any dimension that drifts stops the cell. First articles on the CMM, production sampled against the same dimensions, and dimensional reports with material certs where PPAP levels are required.
