Drilling JGS2 Quartz Glass – JGS2 Quartz Glass (CTE 0.55 x 10^-6 /K, 220 nm – 2.5 um); Drilling to +/-0.02 mm hole position. No minimum order; DFM review included with every RFQ.
The combination of JGS2 Quartz Glass and Drilling comes up constantly in RFQs for a reason – the material offers lower oh than jgs1, and Drilling is the right way to get accurate geometry into it. Expect +/-0.02 mm hole position and exit-chip controlled below 0.1 mm.

Design guidance
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.
- Process boundary: hole-to-edge distance should stay above 1.5x thickness to protect strength.
- 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
Drilling earns its place through through-holes, blind holes and countersinks at densities beyond 1,000 holes per part. Its boundary condition – hole-to-edge distance should stay above 1.5x thickness to protect strength – is the first thing our DFM review checks.
Beyond this page, JGS2 Quartz Glass routinely runs through etching, lapping, dicing, coring in our shop – most real parts combine two or three of these steps.

Common questions
What equipment runs the drilling work?
Diamond core drills, ultrasonic assist and laser percussion heads.
Is there a minimum order for drilling 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.
