Ultra-High Precision Granite Machine Bases & Components | ZHHIMG®
The Foundation of Nano-Level Accuracy for Global High-Tech Industries
In the world of ultra-precision machining and metrology, your equipment is only as stable as the ground it stands on. At ZHHIMG® (Zhonghui Group), we provide the literal “bedrock” for the world’s most demanding technologies.Leveraging our unique ZHHIMG® Black Granite—with a superior density of ≈3100kg/m³—we manufacture precision granite components that outperform European and American counterparts in physical stability and vibration dampening.

Granite Parallels
The fundamental principle underlying parallelism error measurement is to utilize the high-precision reference plane of a granite parallelism gauge as an ideal datum surface, and then quantify the maximum deviation—typically expressed as the distance between two parallel planes—between the workpiece surface and this datum surface.

Precision Granite Mechanical Component with Central Bore
Unlike metal frames that gradually deform due to internal stress release, granite maintains geometry for decades. That is why granite is widely used in CMM machines, semiconductor equipment bases, and precision measuring instruments.

Ultra-Precision Granite Machine Base with Linear Guide Assembly
Scientific Insight: Why Granite Ensures Long-Term Accuracy
Unlike cast iron, granite contains no internal casting stress. Metal structures gradually deform due to stress release, temperature fluctuation, and oxidation. -
Granite Surface Plate with stand
In precision inspection and measurement, granite surface plates—typically mounted on adjustable, vibration-damped stands—are widely recognized as the foundational reference standard in industrial metrology. Far exceeding the functional scope of ordinary workbenches, they serve as stable, thermally stable, and geometrically accurate reference planes for calibration, alignment, and high-accuracy dimensional verification.
