Tri-Ply Circles
Circle Tolerances: Diameter, Thickness & What to Specify
Tolerance is a price lever: tighter than necessary and you pay for precision you can’t use; looser than necessary and vessels vary.
Realistic tolerances
- Diameter: ±0.5 mm standard; ±0.25 mm precision (costs more)
- Thickness: ±0.05 mm typical for 2.0 mm circles
- Flatness: critical for auto-feed presses - specify max bow
- Edge: deburred, no sharp burrs over 0.1 mm
Tolerance vs price
Halving a tolerance roughly doubles inspection/sorting cost at the supplier. Specify what your process needs - then verify on incoming AQL.
PO language
"460 mm dia ±0.5, 2.0 mm ±0.05, deburred edges, flat within 1 mm" - complete, verifiable, quotable.
Frequently asked questions
What diameter tolerance is standard for circles?
±0.5 mm is standard; ±0.25 mm is available as precision grade at higher cost.
