Why Professionals Choose UNPARALLELED® Black Granite
While many manufacturers utilize standard marble or lower-density stone, we exclusively use UNPARALLELED® Black Granite with a density of approximately 3100kg/m³. This material far outperforms European and American black granites in physical properties.
- Superior Stability: Unlike marble, our high-density granite offers minimal internal stress and exceptional resistance to environmental changes.
- Nanometer-Level Precision: Our master technicians-many with over 30 years of experience-hand-lap these surfaces to achieve micron and nanometer-level tolerances.
- Vibration Absorption: The high density and natural structure of our granite provide the world-class dampening required for high-speed laser and semiconductor processes.

Maintenance for Lifelong Accuracy
To ensure your UNPARALLELED® Precision Granite Mechanical Base maintains its (Walking Electronic Level) status, follow these professional maintenance steps:
- Environmental Control: Operate in a temperature-controlled environment to prevent thermal expansion/contraction of the overall system.
- Cleanliness: Clean surfaces daily with specialized granite cleaners or high-purity alcohol to prevent abrasive dust buildup.
- Load Distribution: Ensure the base is mounted on its designated support points to maintain the calibrated flatness.
- Regular Recalibration: Schedule annual inspections using traceable metrology tools to account for any foundation settling or environmental wear.

FAQ
Why choose UNPARALLELED® Black Granite over marble?
Marble lacks the stability required for ultra-precision. We exclusively use UNPARALLELED® Black Granite (3100kg/m³) because its density and physical properties are superior to standard black granites, ensuring the highest level of stability and precision.
How do you guarantee nanometer-level accuracy for large components?
We combine the world's most advanced metrology equipment-like Renishaw laser interferometers-with the expertise of master technicians who have 30+ years of manual lapping experience. Every product is verified in our 10,000 m² constant temperature, vibration-free workshop.
Is your equipment compliant with international standards?
Yes. We are the only company in the industry with ISO 9001, 45001, 14001, and CE certifications. Our measurements are traceable to national institutes and comply with global standards including DIN (Germany), ASME (USA), and JIS (Japan)
The UNPARALLELED® Commitment
As the only company in the industry to hold ISO 9001, ISO 45001, ISO 14001, and CE certifications simultaneously, we guarantee total transparency. Our quality policy is simple: "The precision business can't be too demanding". We provide global support to industry giants like GE, Apple, Samsung, and Bosch, as well as leading research institutes worldwide.
