Quick answer: Glass With Rounded Corners covers R0.5 – R50 mm, matched to drawing. Prototypes ship in 5-10 working days.
glass with rounded corners – manufactured to drawing with documented tolerances, from single prototypes to production.
The numbers
| Feature | Rounded Corners |
|---|---|
| Capability | R0.5 – R50 mm, matched to drawing |
| RFQ inputs | PDF/DXF/STEP drawing, quantity brackets, surface and edge spec |
Getting the drawing right
Before sending the RFQ, check these against your drawing:
- Feature rule: R2 mm and larger survive handling far better than R0.5.
- Over-specification is the quiet budget killer: a 20/10 scratch-dig face costs roughly three times an 80/50 face, so grade each surface individually.
For the complete framework, see the tolerance design guide and the holes and edges design guide.
Process window
These features are produced by cnc machining or edge grinding. Capability: R0.5 – R50 mm, matched to drawing. Design rule worth copying onto the drawing: R2 mm and larger survive handling far better than R0.5.
Application context
The recurring buyers of glass with rounded corners: oled packaging (cover lids, frit-seal frames, fill-port plates); microfluidic devices (chips, manifolds, via plates, bonded stacks); aerospace optics (sensor windows, star-tracker flats, radiation-tolerant ports).
The fastest route to a quote is geometry: use the 3D builder below, draw a dimensioned 2D drawing from it, or open the site-wide custom glass machining 3D + 2D builder for fully custom parts.

Common questions
Do parts ship with inspection data?
Dimensional reports, surface certificates and material certs per melt are available; specify the level on the RFQ.
What is the design rule for rounded corners?
R2 mm and larger survive handling far better than R0.5.
Is there a minimum order for glass with rounded corners?
No. Single prototypes are accepted, and pricing steps down at 10, 100 and 1,000 pieces.
How fast can prototypes ship?
Machined prototypes ship in 5 – 10 working days. Coated or bonded parts add 1 – 2 weeks depending on queue slots.
What files do you need for a quote?
A dimensioned PDF plus DXF or STEP geometry. If only a sketch exists, our drawing review service formalizes it before quoting.
