Ultra-Precision Granite Gantry & Machine Components

In the world of ultra-precision, the base material is not a commodity—it is the ultimate determinant of accuracy. ZHONGHUI Group insists on using only our proprietary ZHHIMG® High-Density Black Granite, a material that significantly outperforms lighter, more porous granites and inferior marble substitutes.

The ZHHIMG® Advantage:

●  Extreme Density: Our certified material boasts a high density of approximately $\mathbf{3100 \text{ kg/m}^3}$, providing far superior damping properties and structural rigidity compared to typical European or American black granites.

●  Inherent Stability: The fine-grain structure minimizes the material's thermal expansion coefficient and hygroscopicity, ensuring that dimensional accuracy is maintained across temperature and humidity variations.

●  Vibration Mastery: Granite naturally dampens vibration 5-10 times better than cast iron or steel. Our high-density composition translates this characteristic into a noise-free, stable platform, critical for sub-micron and nanometer-level operations (e.g., laser etching or CMM scanning).

●  A Matter of Integrity: As the industry standard-bearer, ZHONGHUI Group maintains a strict "No Cheating, No Concealment, No Misleading" commitment, a stand against the use of cheap, unstable marble that compromises end-product quality.
