Dicing JGS2 Quartz Glass – JGS2 Quartz Glass (CTE 0.55 x 10^-6 /K, 220 nm – 2.5 um); Dicing to +/-0.01 mm index accuracy. No minimum order; DFM review included with every RFQ.
dicing jgs2 quartz glass is a materials problem before it is a machining problem. JGS2 Quartz Glass has visible and near-ir clarity 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.

Specification advice
The shop-floor rules that matter here:
- Material note: thicker blanks need stress-relief annealing before tight-flatness grinding.
- 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.
For the complete framework, see the tolerance design guide and the holes and edges design guide.
Capabilities and limits
The core strength of Dicing is singulating wafers into dies with tight index accuracy and low chipping. The honest limit: straight-line cuts only; contours route to laser cutting instead. Both belong on the drawing before quoting, not after.
One material, many routes: on JGS2 Quartz Glass we also quote sandblasting, grinding, cnc machining, edge grinding, and multi-step drawings are the norm rather than the exception.

Buyer questions, answered
What equipment runs the dicing work?
Automatic dicing saws with resin and metal-bond blades.
Is there a minimum order for dicing jgs2 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.
