ZHHIMG® Precision Granite Triangle Square
The ZHHIMG® Precision Granite Triangle Square is a high-accuracy 90-degree reference tool designed for precision inspection, machine calibration, layout alignment, and metrology verification in advanced manufacturing environments.
Manufactured from ZHHIMG® high-density black granite (≈3100 kg/m³), this triangle square delivers exceptional geometric stability and long-term dimensional reliability. It is widely used in coordinate measuring machine (CMM) workshops, precision machining facilities, metrology laboratories, and semiconductor equipment assembly environments.
Unlike cast iron or fabricated steel squares, granite triangle squares do not deform due to internal stress release or temperature variation, making them ideal for long-term precision reference applications.

1. High Geometric Stability
Natural granite structure ensures long-term stability without deformation or stress release.
2. Superior Vibration Damping
Ideal for precision environments where micro-vibration can affect measurement accuracy.
3. Wear-Resistant Reference Surface
Unlike metal tools, granite does not develop burrs, rust, or surface wear over time.
4. Thermal Neutral Behavior
Stable performance under varying workshop temperature conditions.
5. Long Service Life
Suitable for continuous industrial use without recalibration drift.
6. Metrology-Grade Manufacturing Control
Each unit is processed under strict grinding, lapping, and inspection procedures.
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.
