Quartz Glass With Grooves: Quartz Glass (CTE 0.59 x 10^-6 /K, 260 nm – 2.5 um); depth from 0.2 mm, V, U or square section. Single-piece prototypes to production volumes, quoted from your drawing.
Buyers come to quartz glass with grooves with two kinds of parts: catalog-adjacent blanks that need accurate finishing, and genuinely custom geometry. We quote both from the same dataset – GE214-equivalent, semiconductor grade stock in 0.20 – 60 mm, blanks to 450 mm diameter.

DFM notes from the shop floor
Before sending the RFQ, check these against your drawing:
- Material note: natural-quartz batches vary in metallic ppm, so semiconductor lots need certs per melt.
- Feature rule: depth under 50% of thickness preserves 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.
Capabilities and limits
One material, many routes: on Quartz Glass we also quote dicing, laser cutting, cnc machining, sandblasting, and multi-step drawings are the norm rather than the exception.
These features are produced by cnc machining or ultrasonic machining. Capability: depth from 0.2 mm, V, U or square section. Design rule worth copying onto the drawing: depth under 50% of thickness preserves strength.
Typical applications

Buyer questions, answered
How does Quartz Glass behave under heat?
CTE is 0.59 x 10^-6 /K and continuous service reaches 1,050 C continuous, which is what drives its use where fused from natural quartz crystal matters.
What is the design rule for grooves?
Depth under 50% of thickness preserves strength.
Is there a minimum order for quartz glass with grooves?
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.
