Black Granite Metrology Plate

UNPARALLELED LTD is one of the leading manufacturers and suppliers of black granite metrology plate in China. With abundant experience, we warmly welcome you to buy advanced black granite metrology plate made in China here from our factory. We also accept custom orders.

While many manufacturers use generic marble or low-density stone, we exclusively utilize UNPARALLELED® Black Granite. This isn't just a marketing name; it is a material selected for its superior physical properties that exceed European and American standards.

• Superior Density: With a density of approximately 3100kg/m³, our granite offers significantly better stability and vibration damping than standard black granite or marble.
• Nanometer-Level Flatness: Every plate is finished by master technicians with over 30 years of experience. Their "hand-lapping" technique achieves precision that machines cannot replicate-reaching nanometer-level accuracy.
• Ultimate Stability: Our plates are processed in a 10,000m² constant temperature and humidity facility built on 1000mm thick military-grade concrete with dedicated anti-vibration trenches to ensure zero environmental interference during calibration.
• Certified Authority: As the only company in the industry with ISO 9001, 14001, 45001, and CE certifications, our products are traceable to national metrology institutes.

We operate the world's most advanced processing equipment, allowing us to manufacture components of unprecedented scale:

• Maximum Dimensions: Single-unit lengths up to 20m, widths up to 4000mm, and thickness up to 1000mm.
• Weight Capacity: Our facilities can handle single components weighing up to 100 tons.
• Global Standards Compliance: We strictly adhere to DIN 876, ASME B89.3.7-2013, JIS B7513, and GB standards.

UNPARALLELED® Black Granite Metrology Plate and surface plates are the trusted foundation for:

• Semiconductor & PCB: Lithography equipment, drilling machines, and AOI (Automated Optical Inspection).
• Metrology & Quality Control: CMM (Coordinate Measuring Machines), laser interferometers, and profile meters.
• High-Tech Manufacturing: Ultra-precision CNC machines, picosecond/femtosecond laser equipment, and Perovskite coating machines.
• New Energy: Lithium battery testing equipment and industrial CT scanning bases.

Unlike metals, granite is naturally aged over millions of years, making it free from internal stresses. It has an extremely low coefficient of thermal expansion and is non-magnetic, non-conductive, and corrosion-resistant. For ultra-precision work, granite provides a "dead" surface that absorbs vibration, ensuring that your measurements are a reflection of the part, not the environment.

To maintain the nanometer-level precision of your UNPARALLELED® plate:

• Keep it Clean: Dust is abrasive. Clean the surface before every use with a dedicated granite cleaner or 90% isopropyl alcohol.
• Rotation: Periodically rotate the use of different areas on the plate to prevent localized wear.
• Environmental Control: Always use the plate in a temperature-controlled environment (ideally 20°C ± 1°C).
• Calibration: We recommend professional re-calibration every 6–12 months depending on usage frequency to ensure ongoing compliance with ISO standards.
