Design guidance
The shop-floor rules that matter here:
- Material note: ultra-thin stock cannot take conventional clamping; parts are machined on wax or UV-tape carriers.
- Hold the controlling dimension (parallelism 2 um) and let secondary dimensions carry standard tolerance – it is the single biggest cost lever.
- 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.
The full rules live in our tolerance design guide and holes and edges design guide.
Process window
Beyond this page, D263 Thin Glass routinely runs through laser cutting, double-side polishing, drilling, cnc machining in our shop – most real parts combine two or three of these steps.
Production route: grinding, lapping, double-side polishing – selected per geometry and volume. Edge condition: ground perimeter, squareness 0.02 mm.
Who orders this

Frequently asked questions
Is there a minimum order for d263 thin glass glass spacers?
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.
Do parts ship with inspection data?
Dimensional reports, surface certificates and material certs per melt are available; specify the level on the RFQ.
