Custom Precision Granite Components

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

Setting the Standard for Ultra-Precision Machine Frames

At UNPARALLELED Group, we understand that the performance of any ultra-precision system-be it a Coordinate Measuring Machine (CMM), a high-speed linear motor stage, or advanced semiconductor equipment-is entirely dependent on the stability and accuracy of its foundation. Our custom-engineered Precision Granite Bases and Granite Components are designed to be that unyielding foundation.

The component shown here is a prime example of our capability in manufacturing complex, multi-axis, and assembled granite structures. Far exceeding the scope of simple surface plates, these structures integrate mounting features, air bearing surfaces, and precise alignment characteristics required for demanding applications.

Our products are crafted from proprietary UNPARALLELED® Black Granite, a material selected for its superior physical properties compared to standard granite used in the industry.

Our ability to produce structures of this complexity and precision is underpinned by our unique manufacturing ecosystem.

We operate the world's highest-capacity precision granite fabrication facility, utilizing advanced Taiwanese grinding equipment capable of processing components up to 6000 mm. Our 10000 m² constant temperature and humidity workshop is engineered with anti-vibration trenches and 1000 mm thick concrete flooring to ensure absolute stability during the final assembly and measurement stages.

Quality is verified using world-class instrumentation, including Renishaw Laser Interferometers and WYLER Electronic Levels, with all calibration traceable to national metrology institutes. Furthermore, our entire staff is rigorously trained in global metrology standards, including DIN, ASME, and JIS, ensuring we meet the most demanding specifications globally. This commitment is why we are the industry's only manufacturer to simultaneously hold ISO 9001, ISO 45001, and ISO 14001 certifications.

This level of precision granite engineering is indispensable in industries where the margin for error is zero. This granite base is perfectly suited for:

• Semiconductor Equipment: Base frames for wafer handling, inspection tools (AOI), and lithography systems.
• Precision Metrology: Base structures for high-end CMMs, large-scale 3D scanners, and contour measuring instruments.
• Laser Processing: Ultra-stable granite assembly platforms for femtosecond and picosecond laser cutting and welding systems.
• High-Speed Automation: Foundation elements for XY tables, linear motor stages, and granite air bearing systems, ensuring flawless straightness and motion control.
• Inspection Technology: Base components for X-Ray/CT inspection systems and optical measuring devices.

A precision base is a long-term investment. Proper maintenance ensures its accuracy is preserved for decades:

• Cleaning: Regularly use a specialized, non-corrosive cleaner (like an AMPG Granite Surface Plate Cleaner equivalent) to remove surface contaminants without compromising flatness. Never use standard soap or household detergents.
• Handling: While robust, avoid dropping heavy tools or components directly onto the surface to prevent chips or localized impact damage.
• Recalibration: Adhere to a strict annual or semi-annual recalibration schedule using traceable instrumentation (e.g., laser interferometers) to verify continued compliance with required flatness grades.

By choosing an UNPARALLELED® Precision Granite Base, you are not just purchasing a component; you are investing in a foundation built on certified quality, unparalleled stability, and the highest standards of ultra-precision engineering.
