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
The shop-floor rules that matter here:
- 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 cnc machining, grinding, coring, lapping in our shop – most real parts combine two or three of these steps.

Buyer questions, answered
What tolerances are achievable on JGS1 Quartz Glass parts?
Ground features hold +/-0.01 mm and lapped thickness reaches +/-0.003 mm. UV-grade surfaces must be polished without subsurface damage that scatters below 250 nm.
What thickness range do you stock for JGS1 Quartz Glass?
Standard stock spans 0.10 – 30 mm, with blanks up to 300 mm diameter. Other formats are sourced per order.
How does JGS1 Quartz Glass behave under heat?
CTE is 0.55 x 10^-6 /K and continuous service reaches 1,100 C continuous, which is what drives its use where deep-UV transmission to 185 nm matters.
What accuracy does edge grinding hold?
Chamfer +/-0.05 mm with minimum features of 0.1 mm chamfer leg. Profiles below 0.1 mm leg length are lapped by hand and priced per edge.
What equipment runs the edge grinding work?
CNC edge grinders with profiled diamond wheels.
