Laser Cutting D263 Thin Glass – D263 Thin Glass (CTE 7.2 x 10^-6 /K, 350 nm – 2.0 um); Laser Cutting to +/-0.02 mm contour. No minimum order; DFM review included with every RFQ.
We laser-cut D263 Thin Glass daily, in thicknesses from 0.03 – 6 mm. The controlling numbers: +/-0.02 mm contour working tolerance, 0.10 mm hole diameter minimum features, and sealed edge, chip-free off the machine. Where the drawing asks for more, downstream lapping and polishing take over.

Capabilities and limits
The core strength of Laser Cutting is chip-free free-form contours and dense hole arrays in thin and ultra-thin glass. The honest limit: aspect ratio in a single pass tops out near 10:1; thicker sections shift to coring or ultrasonic work. Both belong on the drawing before quoting, not after.
One material, many routes: on D263 Thin Glass we also quote grinding, drilling, cnc machining, and multi-step drawings are the norm rather than the exception.
Specification advice
Three items decide most of the cost and lead time on this work:
- Material note: ultra-thin stock cannot take conventional clamping; parts are machined on wax or UV-tape carriers.
- Process boundary: aspect ratio in a single pass tops out near 10:1; thicker sections shift to coring or ultrasonic work.
- 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.

Buyer questions, answered
What equipment runs the laser cutting work?
Picosecond and CO2 laser stations with vision registration.
Is there a minimum order for laser cutting d263 thin 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.
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.
