Dicing JGS1 Quartz Glass – JGS1 Quartz Glass (CTE 0.55 x 10^-6 /K, 185 nm – 2.5 um (UV grade)); Dicing to +/-0.01 mm index accuracy. No minimum order; DFM review included with every RFQ.
dicing jgs1 quartz glass is a materials problem before it is a machining problem. JGS1 Quartz Glass has deep-uv transmission to 185 nm and a Knoop hardness of 500 kg/mm2, so the dicing recipe – feeds, coolant, tooling – differs from what works on ordinary float glass. The line runs automatic dicing saws with resin and metal-bond blades and holds +/-0.01 mm index accuracy.

DFM notes from the shop floor
Three items decide most of the cost and lead time on this work:
- Material note: UV-grade surfaces must be polished without subsurface damage that scatters below 250 nm.
- Process boundary: straight-line cuts only; contours route to laser cutting instead.
- 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
Dicing earns its place through singulating wafers into dies with tight index accuracy and low chipping. Its boundary condition – straight-line cuts only; contours route to laser cutting instead – is the first thing our DFM review checks.
Beyond this page, JGS1 Quartz Glass routinely runs through etching, ultrasonic machining, lapping, cnc machining in our shop – most real parts combine two or three of these steps.

Frequently asked questions
What equipment runs the dicing work?
Automatic dicing saws with resin and metal-bond blades.
Is there a minimum order for dicing jgs1 quartz 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.
