Custom Si₃N₄ Ceramic Stepped Calibration Block — 4 Micro-Steps, ±2μm
The Challenge
Customer provided a complete drawing and tight tolerance requirement: four micro-steps on a silicon nitride ceramic block, each held within ±0.002mm of nominal height.
What We Built
- 104×74.5×7mm silicon nitride (Si₃N₄) ceramic block
- 4 steps: 0.03 / 0.05 / 0.08 / 0.11mm
- Step height tolerance: ±0.002mm
- Verified on Mitutoyo height gauge
Why Silicon Nitride
Silicon nitride is one of the hardest engineering ceramics available — Hᵥ720. It’s tougher than standard industrial ceramic, with superior wear resistance and fracture toughness. Ideal for reference standards that will see frequent handling and need to hold their accuracy over years of use.
Applications
- Precision height calibration reference
- Gauge block calibration verification
- Height gauge accuracy validation
- Measurement equipment performance check
