Unrivaled Advantages & Features

1、Superior Material: ZHHIMG® Black Granite

Exceptional Density & Stability: Sourced exclusively from our high-density ZHHIMG® Black Granite, boasting a density of approximately 3100 kg/m³. This significantly surpasses standard granite and marble in physical performance, ensuring unparalleled long-term stability and resistance to environmental fluctuations.
Intrinsic Vibration Damping: The natural crystalline structure of our granite provides inherent vibration absorption, minimizing resonant frequencies and crucial for maintaining micron and nanometer-level precision in dynamic operations.
Low Thermal Expansion: Granite's low coefficient of thermal expansion ensures dimensional stability across varying temperatures, critical for consistent performance in precision environments.
Non-Magnetic & Corrosion Resistant: Ideal for sensitive electronic and optical applications where magnetic interference or material degradation cannot be tolerated.

2、Engineered for Extreme Precision

Nanometer-Level Flatness: Our advanced lapping techniques, refined over 30 years of artisanal expertise, achieve flatness and straightness tolerances down to the nanometer range, far exceeding industry standards like DIN 876, ASME, and JIS.
Massive Scale, Uncompromised Accuracy: With the capability to process single units weighing up to 100 tons and lengths reaching 20 meters, ZHHIMG® offers solutions for even the largest ultra-precision equipment, all while maintaining the tightest tolerances.

State-of-the-Art Manufacturing Environment: Produced in our 10,000 m2 temperature and humidity-controlled facility, featuring military-grade 1000mm thick concrete flooring and anti-vibration trenches, ensuring a perfectly stable manufacturing and metrology environment.
