Hole Position Tolerance in Glass: true position +/-0.02 mm across 300 mm. Single-piece prototypes to production volumes, quoted from your drawing.
Drawings fail at the tolerance block more than anywhere else. For hole position tolerance in glass the achievable envelope is true position +/-0.02 mm across 300 mm – the method is vision-registered drilling.
The numbers
| Held tolerance | true position +/-0.02 mm across 300 mm |
|---|---|
| Method | vision-registered drilling |
| Reference standard | ISO 2768 + drawing GD&T |
| RFQ inputs | PDF/DXF/STEP drawing, quantity brackets, surface and edge spec |
Getting the drawing right
The shop-floor rules that matter here:
- Cite ISO 2768 + drawing GD&T on the drawing so both sides measure the same way.
- 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.
Where these parts end up
Orders for hole position tolerance in glass cluster in laser systems (windows, beam splitters, debris shields); led packaging (groove covers, phosphor carriers, package windows); laboratory instruments (cuvettes, sight glasses, stir-cell windows).
If the part is easier to draw than describe, the custom glass machining 3D + 2D builder turns dimensions into an RFQ in a few minutes.

Buyer questions, answered
Do parts ship with inspection data?
Dimensional reports, surface certificates and material certs per melt are available; specify the level on the RFQ.
Which standard governs this?
ISO 2768 + drawing GD&T, verified by vision-registered drilling.
Is there a minimum order for hole position tolerance in glass?
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.
