Quick answer: FTO Coated Glass Machining Services covers FTO Coated Glass (CTE substrate dependent, 80 – 82% visible @ 7 ohm/sq). Prototypes ship in 5-10 working days.
Buyers come to fto coated glass machining services with two kinds of parts: catalog-adjacent blanks that need accurate finishing, and genuinely custom geometry. We quote both from the same dataset – TEC-7, TEC-15 equivalents stock in 1.1 – 3.2 mm substrates, blanks to 360 x 300 mm.
Key parameters

DFM notes from the shop floor
Three items decide most of the cost and lead time on this work:
- Material note: the harder FTO film abrades diamond tooling faster and edges need post-cut inspection for film lift.
- 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
Beyond this page, FTO Coated Glass routinely runs through edge grinding, etching, drilling, laser cutting in our shop – most real parts combine two or three of these steps.
Where these parts end up
Orders for fto coated glass machining services cluster in semiconductor equipment (view ports, wafer carriers, plasma rings, chamber windows); industrial displays (touch covers, gauge windows, printed bezels); laboratory instruments (cuvettes, sight glasses, stir-cell windows). Background reading on the underlying material science: ScienceDirect: FTO glass.
The fastest route to a quote is geometry: use the 3D builder below, draw a dimensioned 2D drawing from it, or open the site-wide custom glass machining 3D + 2D builder for fully custom parts.

Common questions
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.
What tolerances are achievable on FTO Coated Glass parts?
Ground features hold +/-0.01 mm and lapped thickness reaches +/-0.003 mm. The harder FTO film abrades diamond tooling faster and edges need post-cut inspection for film lift.
