Ultra-Precision Black Granite Machine Bases & Bridges
We firmly resist the use of cheap marble substitutes common among smaller manufacturers. Instead, we exclusively use ZHHIMG® Black Granite, a material that outperforms European and American alternatives in every physical metric:
• Superior Density: Our granite reaches a density of ≈ 3100kg/m³, offering unparalleled stability.
• Mechanical Integrity: High stiffness and exceptional physical properties make it the ideal substrate for sub-micron movements.
• Unmatched Scale: Our facilities can process single-unit components up to 20 meters in length and 100 tons in weight.

Our granite bridges and machine bases are the standard for world-class enterprises like GE, Samsung, Apple, and Bosch. They are specifically designed for:
• Semiconductor Manufacturing: Wafer processing and lithography bases.
• Automated Optical Inspection (AOI): Ultra-stable foundations for industrial CT and X-ray systems.
• Precision Laser Systems: Stable platforms for femtosecond and picosecond laser drilling.
• Metrology Equipment: The fundamental base for CMMs and contour measurement devices.
We use various techniques during this process:
● Optical measurements with autocollimators
● Laser interferometers and laser trackers
● Electronic inclination levels (precision spirit levels)

To ensure your ZHHIMG® granite maintains its "walking electronic level" accuracy for decades, follow these professional protocols:
1.Thermal Stability: Operate only within temperature-controlled environments to prevent geometric shifting.
2.Surface Cleansing: Use specialized granite cleaners or high-purity alcohol; avoid corrosive chemicals that could degrade the stone's surface.
3.Support Points: Always install the base on its original designated support points (Bessel points) to minimize gravitational deflection.
4.Avoid Burrs: While granite does not "burr" like metal when scratched, ensure any surface debris is removed immediately to prevent interference with air bearings or moving parts.
Scientific Insight: The "Why" of Granite
Why do the world’s leading universities and metrology institutes (like the National University of Singapore and British Metrology Institute) trust ZHHIMG® granite? Granite provides a unique combination of high damping, low thermal expansion, and total immunity to magnetism and rust. Our master lapping technicians can "feel" a single micron, ensuring that every product is not just a piece of stone, but a scientific instrument.
