High-density granite for CMM machines
Imagine a perovskite coating production line where even a microscopic vibration can cause critical film thickness deviations. A ZHHIMG® granite base acts like a silent mountain, absorbing all external disturbances. Or consider an AOI optical inspection system, where surface flatness directly dictates image recognition accuracy—a deviation of just 0.1μm could lead to an entire batch being scrapped. This is why an increasing number of engineers are saying: “Replacing that ‘fake granite’ base was the first step in genuinely improving our yield rate.”

ZHHIMG® Precision Granite Triangle Square
In precision engineering, angular deviation is one of the most critical sources of cumulative error. Even a small misalignment in machine setup or fixture calibration can lead to significant production inaccuracies.
The ZHHIMG® Precision Granite Triangle Square is engineered to eliminate this risk by providing a stable, wear-resistant, and thermally inert reference surface for angle verification.
It is not simply a measuring tool—it is a foundational reference standard used to ensure that every downstream process maintains geometric correctness.

Precision Granite Surface Plate with Steel Stand
Granite is the preferred material for precision metrology because:
It does not rust or corrode
It has low thermal expansion
It absorbs vibration better than metal
It maintains flatness over decadesThis is why nearly all high-end inspection systems are built on granite bases rather than steel or cast iron.
