I. Natural Mineral Properties: Eliminate Precision Deformation at the Source to Build an Ultra-Stable Base
The core requirements of high-precision inspection are zero deformation, low drift and high consistency, which are weaknesses that traditional substrates including steel, cast iron and ordinary marble cannot overcome. Metal materials feature high coefficients of thermal expansion. Slight temperature differences in the environment can trigger structural expansion and contraction, and stress fatigue and micro-deformation will occur under long-term load. Ordinary marble has loose texture, uneven density and abundant internal pores with poor stability. It cannot meet the requirements of nanometer-level precision inspection and is commonly used by some manufacturers in the industry to cut corners.
UNPARALLELED exclusive black granite is formed through hundreds of millions of years of geological crystallization, featuring dense and uniform mineral structures without internal residual stress. It fundamentally avoids spontaneous deformation, warping and settlement during long-term service. With an ultra-high density close to 3100kg/m³, far exceeding similar granite from Europe and America and ordinary stone, it delivers extreme structural rigidity and compressive stability. Meanwhile, the material has an extremely low thermal expansion coefficient and strong thermal inertia. In the face of routine workshop temperature fluctuations and thermal radiation from operating equipment, dimensional deformation is negligible. It can maintain stable flatness and parallelism of the equipment reference surface over a long period, freeing high-precision inspection equipment from temperature-induced accuracy interference and enabling continuous and stable micro-nano inspection output.
In addition, granite boasts excellent vibration damping, corrosion resistance and wear resistance. Micro-vibrations generated by equipment operation, personnel movement and airflow fluctuations in inspection workshops are invisible triggers of deviations in high-precision inspection data. The dense granite structure efficiently absorbs and attenuates various micro-vibrations to isolate external vibration interference. Moreover, the material is acid and alkali resistant, anti-oxidation and wear-resistant, requiring minimal maintenance and calibration. No reference deviation will occur due to oxidation or abrasion over time, perfectly matching the long-term, high-frequency and high-precision operation requirements of precision inspection equipment.
II. Ultra-Precision Manufacturing Process: Meet Nanometer-Level Inspection Reference Requirements
High-quality raw materials lay the foundation, and extreme machining technology is the core to achieve high-precision matching. Ordinary stone processing can only satisfy general mechanical load requirements and fail to reach the reference precision for precision inspection. Supported by a complete ultra-precision processing system, UNPARALLELED fully unlocks the precision potential of granite frames and achieves dual breakthroughs in substrate advantages and processing precision.
In terms of hardware support, proprietary large precision grinders and heavy-duty processing equipment enable integrated large-size and high-precision machining, breaking the limits of conventional processing dimensions and precision. Monolithic granite frames of extra length, width and thickness can be fabricated without splicing, completely eliminating structural errors and precision loss caused by splicing gaps. Meanwhile, a Class 10000 constant-temperature and constant-humidity cleanroom provides an extreme environment for precision machining and assembly. The thickened super-hard concrete floor, annular anti-vibration trenches and silent crane system comprehensively eliminate vibration and temperature deviation interference during production, ensuring the flatness, perpendicularity and parallelism of every frame reach nanometer standards.
In terms of workforce and standards, senior polishing teams with decades of industry experience are proficient in global metrology standards. Leveraging nanometer-level manual polishing expertise, they achieve ultra-fine finishing of frame reference surfaces, perfectly combining manual know-how with precision equipment. Unlike the rough precision of mass mechanical processing, manual fine polishing can correct subtle errors so that the reference precision of granite frames meets the stringent requirements of various high-end inspection equipment. It provides zero-error bearing references for coordinate measuring machines, optical comparators, laser precision measuring equipment, semiconductor AOI inspection equipment and more.

In semiconductor and optoelectronic inspection, for high-precision scenarios including femtosecond/picosecond laser inspection, semiconductor chip appearance inspection, industrial CT and X-ray precision testing, granite frames can sustain long-term positional accuracy of equipment optical paths and inspection probes. It prevents inspection offset caused by micro-deformation and guarantees the inspection accuracy of micro-nano components.
In new energy and precision machinery inspection, for the testing of precision lithium battery components, cutting tools, precision guide rails and lead screws, core parts of perovskite coating machines and other products, granite frames feature wear resistance, deformation resistance and high rigidity. They adapt to high-frequency mass production inspection, effectively reducing equipment calibration frequency and improving production inspection efficiency and precision stability. Meanwhile, monolithic granite frames have a simple structure and balanced rigidity, compatible with linear motor stages, XY precision motion modules and other automated inspection hardware, enabling high-speed, high-precision and highly stable automated operation of precision inspection equipment.
