Custom Glass With Slots and Grooves – Slots from 0.4 mm wide, grooves from 0.2 mm deep. No minimum order; DFM review included with every RFQ.
A drawing for custom glass with slots and grooves is mostly a conversation about edges and datums. We produce them in fused silica, Borofloat 33, quartz and soda-lime at Slots from 0.4 mm wide, grooves from 0.2 mm deep, with width +/-0.02 mm as the controlling tolerance, and finish the perimeter per spec.
The numbers
| Geometry | Glass With Slots and Grooves |
|---|---|
| Size envelope | Slots from 0.4 mm wide, grooves from 0.2 mm deep |
| Key tolerance | width +/-0.02 mm |
| RFQ inputs | PDF/DXF/STEP drawing, quantity brackets, surface and edge spec |
DFM notes from the shop floor
Three items decide most of the cost and lead time on this work:
- Hold the controlling dimension (width +/-0.02 mm) and let secondary dimensions carry standard tolerance – it is the single biggest cost lever.
- 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
Production route: cnc machining, ultrasonic machining, etching – selected per geometry and volume. Edge condition: chamfered 0.1 – 0.5 mm as standard.
Typical applications
The recurring buyers of custom glass with slots and grooves: mems devices (cap wafers, TGV substrates, motion-sensor lids); ccd inspection equipment (CCD cover plates, reference grids, stage glass); scientific instruments (reference flats, cells, prism mounts, stage inserts).

Buyer questions, answered
Do parts ship with inspection data?
Dimensional reports, surface certificates and material certs per melt are available; specify the level on the RFQ.
What sizes are available for glass with slots and grooves?
Slots from 0.4 mm wide, grooves from 0.2 mm deep, held to width +/-0.02 mm.
Is there a minimum order for custom glass with slots and 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.
