Ultra-Precision Black Granite Bridge Structure for CMM & Semiconductor Equipment
• Unmatched Density & Stability: We refuse to use cheap marble. Our material density hits ~3100kg/m³, providing the rigidity needed for high-speed scanning without deformation.
• "Walking Electronic Level" Craftsmanship: Our components aren't just machined; they are finished by masters with over 30 years of experience. They hand-scrape and polish surfaces to micron-level precision, possessing a "feel" that machines alone cannot replicate.
• Integrated Motion Solutions: As seen in the image, we can embed stainless steel inserts, air bearing ways, and linear motor tracks directly into the granite, creating a seamless, monolithic structure.
• Certified Quality: Produced in our 10,000m² constant temperature/humidity workshop, every inch is verified by Renishaw laser interferometers and Swiss WYLER electronic levels.

Imagine running a high-speed optical inspection for smartphone components. Any vibration from the factory floor could ruin the measurement. This granite bridge structure acts as a massive shock absorber. Its natural damping capacity is 15x higher than cast iron, effectively "swallowing" vibrations before they reach the sensor. Whether it's for a PCB drilling machine or a lithography machine, this base ensures that the only thing moving is what you intend to move.
We use various techniques during this process:
● Optical measurements with autocollimators
● Laser interferometers and laser trackers
● Electronic inclination levels (precision spirit levels)

Q: Can you manufacture custom sizes for large-scale equipment?
A: Absolutely. Our facility handles single unit weights up to 100 tons and lengths up to 20 meters. We have the heavy-duty cranes and large-scale grinding machines (Taiwan Nante grinders) to handle massive projects.
Q: How does your granite compare to European black granite?
A: Our ZHHIMG® material is sourced from specific veins known for finer grain and higher density (~3100kg/m³) compared to many standard European granites, offering better wear resistance and stability.
Q: Do you provide certification for flatness and straightness?
A: Yes. Every product ships with a comprehensive inspection report traceable to national standards, using calibrated Mahr and Mitutoyo instruments.
