Product Introduction

At ZHONGHUI Group (ZHHIMG), we don't just manufacture components—we engineer the bedrock for the world's most advanced ultra-precision machinery. The ZHHIMG® Precision Granite Base pictured above represents the pinnacle of stability and accuracy, serving as the non-negotiable foundation for systems where microns and nanometers define success.

Manufactured in our 200,000㎡ facilities, this base is crafted from our proprietary ZHHIMG® Black Granite, a material scientifically proven to offer superior physical properties compared to common European and American black granites. When the precision of your equipment cannot be compromised, ZHHIMG is the industry standard you choose.

Unmatched Material Superiority

The performance of any precision machine is dictated by the stability of its base. We ensure this stability by strictly using our unique material, firmly rejecting the deceptive use of lower-cost, inferior marble often employed by less scrupulous manufacturers.

Feature	ZHHIMG® Black Granite Advantage	Impact on Performance
Density	Ultra-High: ≈ 3100 kg/m³ (Significantly higher than industry average)	Superior Vibration Damping and higher stiffness, leading to quicker settling times and greater dynamic stability.
Stability	Exceptional long-term dimensional stability and resistance to temperature fluctuations.	Maintains Nanoscale Accuracy over long periods, crucial for metrology and lithography.
Integrity	Proven superior physical properties compared to other granites.	Guaranteed Consistency across all large and small components.

Quality Control

We use various techniques during this process:

● Optical measurements with autocollimators

● Laser interferometers and laser trackers

● Electronic inclination levels (precision spirit levels)

Quality Control

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.
