Edge Grinding JGS1 Quartz Glass: JGS1 Quartz Glass (CTE 0.55 x 10^-6 /K, 185 nm – 2.5 um (UV grade)); Edge Grinding to chamfer +/-0.05 mm. Single-piece prototypes to production volumes, quoted from your drawing.
The combination of JGS1 Quartz Glass and Edge Grinding comes up constantly in RFQs for a reason – the material offers no bubbles or inclusions in the uv path, and Edge Grinding is the right way to get accurate geometry into it. Expect chamfer +/-0.05 mm and ground C or R profile, polish option.

Specification advice
Before sending the RFQ, check these against your drawing:
- Material note: UV-grade surfaces must be polished without subsurface damage that scatters below 250 nm.
- Process boundary: profiles below 0.1 mm leg length are lapped by hand and priced per edge.
- 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.
What the process holds
Edge Grinding earns its place through edge strength – a finished chamfer roughly doubles the bend strength of a cut edge. Its boundary condition – profiles below 0.1 mm leg length are lapped by hand and priced per edge – is the first thing our DFM review checks.
Beyond this page, JGS1 Quartz Glass routinely runs through coring, polishing, dicing, sandblasting in our shop – most real parts combine two or three of these steps.

Buyer questions, answered
What equipment runs the edge grinding work?
CNC edge grinders with profiled diamond wheels.
Is there a minimum order for edge grinding 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.
