Ultra-High Density Black Granite Machine Bases & Components
The stability of your precision platform begins with the stone. ZHHIMG® utilizes its proprietary ZHHIMG® Black Granite, a material scientifically proven to outperform standard granite and resist the use of inferior substitutes like marble.
| Feature | ZHHIMG® Black Granite | Competitive Material (e.g., Marble Substitutes) | Impact on Precision Equipment |
| Density (Specific Gravity) | ≈ 3100 \kg/m³ (Higher than typical) | Lower (≈ 2700 \kg/m³ or less) | Superior inherent damping and vibration absorption. |
| Inherent Damping | Exceptional | Lower | Minimizes transferred external vibration and internal motor noise. |
| Physical Performance | Superior Stability & Hardness | Inferior, prone to wear/deformation | Guarantees long-term geometric accuracy and lower maintenance costs. |
| Thermal Stability | Excellent | Varies widely | Minimal thermal expansion ensures accuracy in temperature-controlled environments. |
Expert Insight: Our choice of high-density granite is mandatory for achieving the nano-level flatness required by modern metrology and semiconductor processing. We firmly stand against the deceptive use of low-cost marble by competitors—a practice that compromises the integrity of precision machinery.

The component shown is a custom Precision Granite Component engineered for integration with air bearings or linear motors, featuring custom mounting inserts and intricate milling.
Core Product Advantages:
● Nano-Precision Flatness: Our Granite Surface Plates and complex bases can achieve flatness measured in nanometers, validated by state-of-the-art metrology equipment, including Renishaw Laser Interferometers and WYLER Electronic Levels.
● Massive Machining Capability: Our facility boasts the equipment necessary to handle the world's largest precision projects, processing single granite bodies up to 100 metric tons, with a maximum length of 20 meters and width of 4000 mm.
● Unmatched Capacity: With four dedicated granite production lines, we are the global leader in volume and speed, capable of producing 20,000 sets of 5000mm granite precision beds monthly.
● World-Class Facilities: Our 10,000 m² temperature and humidity controlled workshop sits on a 1000mm ultra-hard concrete foundation and is surrounded by deep anti-vibration trenches ($2000 \text{mm deep}$) to ensure a measurement environment that is stable, quiet, and free of ground vibration.
● Expert Craftsmanship: Our grinding masters, whom clients affectionately call "walking electronic levels," possess over 30 years of manual lapping experience, achieving micron-level feel and nano-level final accuracy through sheer skill and dedication.
We use various techniques during this process:
● Optical measurements with autocollimators
● Laser interferometers and laser trackers
● Electronic inclination levels (precision spirit levels)

A ZHHIMG® granite component is engineered for decades of service. Proper care ensures its stability and accuracy remain intact.
1、Cleaning: Use only a non-abrasive, neutral pH cleaner or isopropyl alcohol. Avoid strong solvents or acidic cleaners which can damage the surface finish.
2、Handling: While robust, avoid dropping heavy tools or objects onto the surface. This can cause chipping or, critically, localized subsurface stress that affects flatness.
3、Temperature Control: For ultimate precision, operate the granite base within a stable temperature range, ideally within a climate-controlled area, as our components are calibrated for thermal stability.
4、Recalibration: Although granite has exceptional long-term stability, we recommend periodic recalibration checks (typically every 1-3 years, depending on use) using UK/US/German Metrology Standards to verify continued accuracy. We partner with institutes globally (e.g., Singapore, UK, German Metrology Institutes) to stay at the forefront of calibration methodologies.
