Precision Granite Mechanical Component with Central Bore
The ZHHIMG® Precision Granite Mechanical Component is a high-accuracy structural element engineered for advanced metrology systems, semiconductor equipment, optical alignment platforms, and high-end automation assemblies.
Manufactured from proprietary ZHHIMG® high-density black granite (≈3100 kg/m³), this component integrates a precision-machined central bore with multi-surface reference geometry, ensuring exceptional dimensional stability and long-term structural reliability.
Designed for applications requiring micron or sub-micron accuracy, this granite component serves as a precision mounting interface, optical housing base, rotary axis support structure, or calibration reference block.

High-Density Natural Granite Material
Unlike cast iron or marble substitutes, ZHHIMG® granite provides:
• Superior vibration damping
• Extremely low thermal expansion
• Non-magnetic properties
• Corrosion resistance
• No internal residual stress
• Long-term geometric stability
Density: ≈3100 kg/m³
Compressive strength: High structural rigidity
Aging deformation: None
Granite is a naturally stabilized material formed over millions of years. It does not experience stress release like cast metals.
We use various techniques during this process:
● Optical measurements with autocollimators
● Laser interferometers and laser trackers
● Electronic inclination levels (precision spirit levels)

Granite requires minimal maintenance compared to metal components.
Recommended practices:
1.Maintain stable environmental temperature (20±2°C recommended for high-precision use).
2.Avoid impact from metal tools.
3.Clean with neutral, non-acidic solutions.
4.Keep dust-free when used in optical or semiconductor environments.
5.Periodically verify geometric accuracy using calibrated instruments.
Granite does not rust, corrode, or require anti-oxidation treatments.
