Precision Granite Square – High-Accuracy Metrology & Assembly Reference Tool
Built for Accuracy. Trusted for Stability.
In ultra-precision environments, even a micron-level deviation can compromise the entire system.
The ZHHIMG® Precision Granite Square is engineered to provide stable, repeatable 90° reference geometry, ensuring alignment accuracy across inspection, calibration, and assembly processes.
Unlike metal squares, this granite square delivers superior thermal stability, vibration damping, and long-term dimensional integrity, making it ideal for high-end metrology and semiconductor applications.

✔ Exceptional Dimensional Stability
Granite is naturally resistant to thermal expansion and internal stress, ensuring long-term accuracy without deformation.
✔ Superior Wear Resistance
No burrs, no corrosion — unlike steel tools, granite maintains its geometry even after prolonged use.
✔ Integrated Functional Design
The machined holes allow:
• Easy mounting to fixtures or frames
• Weight optimization
• Integration into automated systems
✔ High Precision Surface
Hand-lapped by experienced technicians with decades of expertise, achieving micron-level accuracy.
✔ Vibration Damping Performance
Ideal for environments requiring high stability, such as optical inspection and laser systems.
We use various techniques during this process:
● Optical measurements with autocollimators
● Laser interferometers and laser trackers
● Electronic inclination levels (precision spirit levels)

Q1: Why choose granite instead of steel square?
Granite offers better thermal stability, no corrosion, and higher vibration damping, making it more reliable for precision environments.
Q2: Can the accuracy be customized?
Yes. ZHHIMG® supports custom accuracy grades, sizes, and hole configurations based on your application.
Q3: Are the holes standard or customizable?
Fully customizable — including diameter, position, and threading options.
Q4: How is accuracy verified?
All products are inspected using advanced metrology equipment (laser interferometers, electronic levels), with traceable calibration certificates.
