JGS2 Quartz Glass Machining Services – JGS2 Quartz Glass (CTE 0.55 x 10^-6 /K, 220 nm – 2.5 um). No minimum order; DFM review included with every RFQ.
Buyers come to jgs2 quartz glass machining services with two kinds of parts: catalog-adjacent blanks that need accurate finishing, and genuinely custom geometry. We quote both from the same dataset – Optical grade, bubble class 1 stock in 0.20 – 40 mm, blanks to 300 mm diameter.

Beyond this page, JGS2 Quartz Glass routinely runs through coring, edge grinding, cnc machining, dicing in our shop – most real parts combine two or three of these steps.
Specification advice
Three items decide most of the cost and lead time on this work:
- Material note: thicker blanks need stress-relief annealing before tight-flatness grinding.
- 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.
Application context
Orders for jgs2 quartz glass machining services cluster in industrial displays (touch covers, gauge windows, printed bezels); semiconductor equipment (view ports, wafer carriers, plasma rings, chamber windows); microfluidic devices (chips, manifolds, via plates, bonded stacks).

Buyer questions, answered
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.
What tolerances are achievable on JGS2 Quartz Glass parts?
Ground features hold +/-0.01 mm and lapped thickness reaches +/-0.003 mm. Thicker blanks need stress-relief annealing before tight-flatness grinding.
What thickness range do you stock for JGS2 Quartz Glass?
Standard stock spans 0.20 – 40 mm, with blanks up to 300 mm diameter. Other formats are sourced per order.
