Granite surface plates are premium-grade, naturally sourced stone measurement tools that provide an exceptionally stable reference plane for precision inspection. These plates serve as ideal datum surfaces for testing instruments, precision tools, and mechanical components—particularly in applications demanding micron-level accuracy.
Why Choose Granite Over Metal?
Unlike conventional metal plates, granite surface plates offer unmatched stability and durability. Sourced from deep underground stone layers that have undergone millions of years of natural aging, granite maintains exceptional dimensional stability without warping due to temperature fluctuations.
Our granite plates undergo rigorous material selection and precision machining to ensure:
✔ Zero Magnetic Interference – Non-metallic structure eliminates magnetic distortion.
✔ No Plastic Deformation – Maintains flatness even under heavy loads.
✔ Superior Wear Resistance – Harder than steel, ensuring long-term accuracy.
✔ Corrosion & Rust Proof – Resists acids, alkalis, and humidity without coating.
Key Advantages of Granite Surface Plates
- Thermal Stability – Extremely low thermal expansion ensures consistent accuracy in varying temperatures.
- Exceptional Rigidity – High stiffness minimizes vibration for precise measurements.
- Low Maintenance – No oiling required; easy to clean and maintain.
- Scratch-Resistant – Durable surface withstands accidental impacts without affecting precision.
- Non-Magnetic & Non-Conductive – Ideal for sensitive metrology and electronic applications.
Proven Performance
Our Grade ’00′ granite plates (e.g., 1000×630mm) retain their original flatness even after years of use—unlike metal alternatives that degrade over time. Whether for CMM bases, optical alignment, or semiconductor inspection, granite ensures reliable, repeatable measurements.
