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

Our unwavering commitment to quality is what sets us apart, from the raw material to the final product.

• Superior Raw Material: We exclusively use our proprietary UNPARALLELED® Black Granite, a material known for its superior physical properties. With an ultra-high density of approximately 3,100 kg/m³, our granite offers exceptional stiffness and vibration dampening compared to standard granite or marble. This ensures a truly stable foundation for your most critical work.
• World-Class Manufacturing: Our state-of-the-art facilities are equipped with advanced machinery, including four ultra-large grinding machines from Taiwan. These can handle single parts up to 100 tons, allowing us to produce granite components with unmatched speed and scale.
• Unrivaled Precision: Our granite surface plates are hand-lapped by master craftsmen with over 30 years of experience. Their incredible tactile sense can achieve a nanometer-level flatness, a precision meticulously verified by top-tier instruments from brands like Wyler and Renishaw. Our dedication to a "no cheating, no concealment, no misleading" policy is a promise of authentic, measurable quality.
• Certifications & Standards: We are the only company in the industry to hold a full suite of international certifications, including ISO 9001, ISO 45001, ISO 14001, and CE. Our products and processes adhere to global standards such as DIN, ASME, JIS, and GB, ensuring they meet the most rigorous demands worldwide.

Our Black Granite Precision Base are an essential tool across a wide range of high-tech industries.

• Metrology & Quality Control: They serve as a definitive reference base for precision instruments like CMMs, optical inspection equipment (AOI), and coordinate measuring machines.
• Precision Manufacturing: They provide a stable platform for the assembly and calibration of semiconductor equipment, laser machines, and CNC devices.
• Research & Development: They are a crucial component in R&D environments for testing and validating new technologies, particularly in the fields of optics and material science.

• Exceptional Flatness: Our plates can achieve nanometer-level flatness, making them ideal for the most demanding inspection tasks.
• High Rigidity & Stability: The high density of UNPARALLELED® Black Granite minimizes thermal expansion and vibration, preserving accuracy in dynamic environments.
• Standard and Custom Sizes: We offer a full range of standard sizes and can also manufacture custom dimensions up to 20m in length to meet your specific project requirements.
• Accessory Compatibility: Our granite plates are designed to be compatible with a variety of accessories, including granite parallels, straight rulers, and V-blocks for comprehensive inspection setups.

To ensure the longevity and precision of your UNPARALLELED® Black Granite Precision Base, follow these simple guidelines:

• Regular Cleaning: Use a lint-free cloth and a specialized granite cleaner to remove dust and debris. Avoid using acidic or abrasive cleaners.
• Proper Handling: Always lift the plate from its base and avoid dragging it. Use proper lifting equipment for larger plates.
• Controlled Environment: Store the plate in a climate-controlled environment to minimize the effects of temperature and humidity fluctuations.
• Periodic Calibration: To maintain absolute accuracy, we recommend periodic recalibration of your surface plate by a certified metrology laboratory.

By choosing UNPARALLELED®, you're not just buying a product-you're investing in a foundation of trust, quality, and precision that is unmatched in the industry.
