Ultra-Precision Granite Component
Precision starts with the source. Unlike competitors who compromise quality with cheaper marble or lower-density granite, ZHHIMG® components are crafted exclusively from our proprietary ZHHIMG® Black Granite—a dense, stable igneous rock chosen for its superior physical properties.
Key Material Specifications (Why Granite Outperforms Metal):
● Exceptional Density: Our material boasts a high density of approximately 3100kg/m³. This significantly contributes to vibration damping and structural rigidity.
● Thermal Stability (Low Coefficient of Thermal Expansion): Granite has a coefficient of thermal expansion up to 80% lower than steel (Source: Industry Metrology Data). This ensures dimensional stability even under the temperature fluctuations common in industrial and cleanroom environments, preventing thermal drift in critical measurements.
● Superior Vibration Damping: The natural mineral composition provides outstanding internal damping properties (up to 15 times better than cast iron). This is crucial for high-speed systems and ultra-precise positioning, minimizing micro-motion errors.
● Non-Corrosive & Non-Magnetic: Granite is inherently rust-proof and non-magnetic, eliminating electromagnetic interference (EMI) and corrosion issues that plague metal bases, making it the ideal choice for high-sensitivity electronics and Cleanroom environments.

ZHHIMG Group is one of the few global manufacturers certified with ISO9001, ISO 45001, ISO14001, and CE—a testament to our commitment to quality, occupational health, safety, and environmental stewardship.
Unmatched Machining and Quality Control:
● Ultra-Large Capacity: Our facilities utilize advanced CNC and gantry machinery capable of handling monolithic blocks up to 100 tons and lengths exceeding 20 meters, providing seamless, high-integrity platforms for your most demanding applications.
● Hand Lapping to Nanometer-Level Flatness: Our proudest asset is our team of master craftsmen, some with over 30 years of manual lapping experience. They finish critical surfaces to sub-micron and nanometer-level flatness, achieving tolerances that consistently exceed international standards (such as ASME B89.3.7 and DIN 876 Grade 00).
● Vibration-Free Metrology Lab: Final inspection occurs in our state-of-the-art 10,000㎡ temperature and humidity-controlled laboratory (constant ± 0.05° variation). The facility features 1000 mm thick anti-vibration concrete floors and 2000 mm deep isolation trenches, ensuring zero external vibration interference for measurement.
● World-Class Calibration: We use the industry’s most advanced equipment, including Renishaw Laser Interferometers and WYLER Electronic Levels, with all gauges traceable to major National Metrology Institutes (e.g., PTB/NIST), ensuring unquestionable authority in your machine's accuracy.
We use various techniques during this process:
● Optical measurements with autocollimators
● Laser interferometers and laser trackers
● Electronic inclination levels (precision spirit levels)
