GR00 Precision Granite Base for Metrology & CMM Stability
- • Zero Thermal Drift: Granite’s low coefficient of thermal expansion means your measurements won’t shift with ambient temperature changes — critical for labs and cleanrooms.
- • Superior Vibration Damping: Absorbs micro-vibrations from motors, pumps, or foot traffic that would otherwise corrupt nanometer-scale readings.
- • Non-Magnetic & Non-Conductive: Safe for use near sensitive electronics, MRI systems, or ESD-sensitive environments.
- • Lifetime Flatness Retention: Unlike cast iron, granite doesn’t warp, rust, or degrade over decades — even under heavy load or humid conditions.
- • Customizable Mounting: Pre-drilled and threaded holes (as shown) allow seamless integration with your existing fixtures, sensors, or robotic arms.

- • Coordinate Measuring Machines (CMMs): Serve as the stable reference plane for probing complex geometries — no more “ghost” deviations caused by base flex.
- • Semiconductor Wafer Inspection: Provide a vibration-free platform for optical scanners detecting sub-micron defects on 300mm wafers.
- • Laser Alignment Systems: Act as the inertial anchor for interferometers measuring linear motion accuracy down to ±0.001mm.
- • Aerospace Component Testing: Support load frames testing turbine blades or composite structures where even 0.005mm error compromises safety certification.
We use various techniques during this process:
● Optical measurements with autocollimators
● Laser interferometers and laser trackers
● Electronic inclination levels (precision spirit levels)
1. Documents together with products: Inspection reports + Calibration reports(measuring devices) + Quality Certificate + Invoice + Packing List + Contract + Bill of Lading(or AWB).
2. Special Export Plywood Case: Export fumigation-free wooden box.

Q: Can I trust the “GR 00” claim without seeing test reports?
A: Absolutely. Every unit ships with a certified calibration report traceable to national standards. We also offer on-site verification using Renishaw laser interferometers upon request.
A: Most “marble” products are actually low-grade limestone or reconstituted stone with inconsistent density. Our black granite is quarried from specific veins known for uniform grain structure and tested for homogeneity before machining.
A: We specialize in OEM customization. Send us your CAD file — we’ll machine it to spec, including blind holes, counterbores, or integrated coolant channels.
