Ceramic machining (select applications)
Alumina, zirconia, and silicon carbide excel at hardness, heat, and electrical isolation—but they’re brittle. We take ceramic jobs when the drawing, tolerances, and inspection plan match what diamond tooling and grinding can deliver. If it’s outside our sweet spot, we’ll say so early.
Risk-aware quoting
Chipping and micro-cracks are process risks—we discuss fixturing and edge conditions before quoting.
Inspection alignment
Critical dimensions may need CMM or comparative gaging—planned with your QA.
Realistic cycles
Ceramics often run slower than metals—lead times reflect grinding passes, not marketing numbers.
Why buyers work with us on this process
Clear scope, documented checks, and quotes aligned with how we actually run production.
Extreme hardness & wear
Great for seals, nozzles, and wear surfaces when metals would gall or erode.
High-temperature stability
Keeps properties where polymers soften and some metals creep.
Electrical isolation
Useful in HV fixtures, probes, and certain sensor stacks.
Dimensional stability
Low thermal expansion in many grades—helps precision metrology hardware.
Chemical resistance
Strong in corrosive media compared to many metals—still verify with your fluid list.
Transparent communication
We’d rather decline than ship a ceramic part that won’t survive assembly torque.
Families we evaluate
Green vs fired stock, grain direction, and supplier blanks change feasibility—send material certificates when you have them.
| Family | Typical traits | Notes |
|---|---|---|
| Alumina (Al₂O₃) | Electrical insulation; cost-effective technical ceramic | Grades vary by purity/porosity |
| Zirconia (ZrO₂) | Higher toughness vs alumina in many formulations | Transformation toughening—supplier dependent |
| Silicon carbide (SiC) | Stiff, thermal shock resistant | Hard on tools—slower cycles |
We do not imply suitability for implantation or regulated medical use unless your specification and contracts say so.
Tolerance discussion (typical bands)
Tighter values may require grinding/lapping and longer cycle time.
| Feature | General (mm) | Tighter (mm) |
|---|---|---|
| Dimension | ±0.05 | ±0.02 |
| Hole diameter | ±0.03 | ±0.01 |
| Flatness (per 100 mm) | 0.05 | 0.02 |
Your drawing remains the acceptance standard; feasibility confirmed at quote.
Typical end uses
Semiconductor & test
Fixtures, probes, and wear inserts where ESD and insulation matter.
Industrial fluid & spray
Nozzles and orifices needing erosion resistance.
Precision metrology
Low CTE components for stable references—paired with careful metrology plans.
Energy & harsh env.
Select high-temp or corrosive service parts—engineered with margin.
Finishing & post-processing
We coordinate common finishes through vetted partners when your drawing calls for them—lead time and cost are quoted together with fabrication.
| Option | What it does | Common use |
|---|---|---|
| Precision grinding | Tight flatness and thickness control. | Sealing faces |
| Lapping / polishing | Mirror or low-Ra surfaces for fluid or optical interfaces. | Valve plugs, optics mounts |
| Sandblast | Matte cosmetic or prep for bonding. | Visible industrial parts |
| Laser mark | Traceability with controlled energy to avoid cracking. | Serialization |
FAQ
Do you machine green (unfired) ceramics?
Sometimes—depends on blank quality and shrink predictions. Share supplier sintering notes.
Can you drill or thread ceramics?
Limited—often prefer as-machined bores plus metal inserts for threads under load.
What makes a good RFQ?
Material grade, blank size, critical dimensions, and how you’ll inspect—photos of similar parts help.
Ready to review your parts?
Send drawings, quantity, destination, and need-by date—we reply with clear questions and realistic timelines.
