Precision You Can Count On
When you choose Istar Machining for your ceramic components, you get:
- Tolerances down to ±0.005 mm (that’s thinner than a human hair!)
- Surface finishes from Ra 0.1–1.6 μm (mirror-like to controlled texture)
- Complex shapes including slots, pockets, and curved surfaces
- Parts up to 450 mm in size for large components
Our precision CNC machining shop uses 5-axis CNC milling, ultrasonic drilling, and diamond grinding to create parts that meet the most demanding specs.
Materials We Work With
Our 5-axis machining capabilities allow us to transform these tough ceramics into precisely engineered parts:
Ceramic Type | Key Properties | Common Uses |
Alumina (Al₂O₃) | Excellent electrical insulation, hard surface | Electronic substrates, pump components |
Zirconia (ZrO₂) | High strength, fracture tough | Medical implants, cutting tools |
Silicon Carbide (SiC) | Extreme hardness, thermal conductivity | Semiconductor parts, brake discs |
Aluminum Nitride (AlN) | High thermal conductivity with electrical insulation | Heat sinks, electronic packaging |
Sapphire | Optical clarity, scratch resistance | Optical windows, smartphone parts |
Industry Applications
Our ceramic CNC machining solutions serve these key industries:

Design Tips for Ceramic CNC Machining
To get the best results and keep costs down:
- Add radii to inside corners – Sharp corners can cause cracks
- Keep wall thickness uniform – This prevents warping during firing
- Design for tooling access – Deep pockets may need special consideration
- Consider assembly needs – Mating surfaces may need extra finishing

Frequently Asked Question
Green-state machining works with unfired ceramic that’s softer and easier to cut. After machining, parts are fired to reach full hardness. This is often cheaper but has more size change during firing.
Fired-state machining works with already-hardened ceramic using diamond tools. This is more expensive but gives tighter tolerances.
Ceramics excel where metals fail:
- Higher temperature resistance (1600°C vs. 1000°C for most metals)
- Better corrosion resistance against acids and chemicals
- Lower weight (40-60% lighter than steel)
- Electrical insulation properties
Standard tolerances are ±0.005 mm, but we can achieve ±0.002 mm for critical features using our precision grinding services.
Yes! Our rapid CNC machining services can deliver ceramic prototypes in as little as 5-7 days.
