Getting the drawing right
Three items decide most of the cost and lead time on this work:
- Feature rule: corner radius R0.5 mm minimum for milled pockets.
- 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.
Capabilities and limits
These features are produced by ultrasonic machining or etching or cnc machining. Capability: pockets with 5 um floor flatness available. Design rule worth copying onto the drawing: corner radius R0.5 mm minimum for milled pockets.
Application context
Orders for glass with cavities cluster in machine vision (camera windows, ring-light diffusers, calibration plates); industrial displays (touch covers, gauge windows, printed bezels); medical diagnostics (flow cells, slides, microplate bottoms, cuvette windows).

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 cavities?
Corner radius R0.5 mm minimum for milled pockets.
Is there a minimum order for glass with cavities?
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.
