Quick answer: Glass With Blind Holes covers depth control +/-0.05 mm, flat or radiused bottom. Prototypes ship in 5-10 working days.
glass with blind holes – manufactured to drawing with documented tolerances, from single prototypes to production.
The numbers
| Feature | Blind Holes |
|---|---|
| Capability | depth control +/-0.05 mm, flat or radiused bottom |
| 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: leave at least 30% of thickness under the bottom.
- 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.
Manufacturing capability
These features are produced by ultrasonic machining or cnc machining. Capability: depth control +/-0.05 mm, flat or radiused bottom. Design rule worth copying onto the drawing: leave at least 30% of thickness under the bottom.
Who orders this
Orders for glass with blind holes cluster in ccd inspection equipment (CCD cover plates, reference grids, stage glass); machine vision (camera windows, ring-light diffusers, calibration plates); optical sensors (sensor windows, filter caps, lens covers).

Frequently asked 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 blind holes?
Leave at least 30% of thickness under the bottom.
Is there a minimum order for glass with blind holes?
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.
