Precision Granite Bases Cmm Metrology

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

Each granite base is meticulously manufactured in our temperature- and humidity-controlled facility. With advanced CNC and grinding equipment capable of handling units up to 20 meters in length and 100 tons in weight, UNPARALLELED ensures precision that exceeds international standards such as DIN 876, ASME B89, JIS B7513, and GB/T 20428.

Our proprietary black granite has a density of approximately 3100 kg/m³, offering superior stiffness and minimal thermal expansion compared to European and American black granite. This ensures dimensional stability even under temperature fluctuations, making it ideal for long-term precision operation.

• Exceptional Dimensional Stability: Resistant to temperature and humidity variations, maintaining micron-level precision over time.
• Superior Damping Performance: Effectively absorbs mechanical vibrations, ensuring consistent measurement accuracy and smoother machine motion.
• High Load Capacity: Supports large-scale CNC and CMM systems with unmatched rigidity.
• Non-Magnetic and Corrosion-Free: Ideal for sensitive measuring and semiconductor applications.
• Customization Available: Complete design and assembly solutions for air-bearing systems, motion stages, and integrated precision structures.

UNPARALLELED® Precision Granite Bases Cmm Metrology are widely used in:

• Semiconductor and display manufacturing equipment
• PCB drilling and routing machines
• Coordinate measuring machines (CMMs)
• Precision laser and optical inspection systems
• Metrology instruments
• Linear motor and air-bearing motion platforms
• High-end CNC machining centers
• Industrial CT and X-ray inspection systems

At UNPARALLELED, precision is verified using world-class metrology instruments, including Renishaw laser interferometers, WYLER electronic levels, and Mitutoyo surface roughness testers. Every product is accompanied by calibration certificates traceable to national metrology institutes, ensuring full reliability and traceability.

To maintain long-term accuracy, the granite surface should be kept clean and free from dust or oil. Avoid exposure to sudden temperature changes or mechanical shocks. Periodic re-lapping by certified technicians is recommended to maintain flatness and precision performance.

UNPARALLELED® - The Standard of Precision.
Our Precision Granite Bases Cmm Metrology have become the benchmark for quality and innovation in ultra-precision manufacturing, trusted by global leaders such as GE, Samsung, and Apple.
