High precision, superior stability and excellent wear resistance are the core requirements of ultra-precision equipment manufacturing. As the core benchmark carrier of precision equipment, granite bases directly determine the detection accuracy, operational stability and service life of the entire machine. With the rapid upgrading of the global ultra-precision industry, common industry problems such as inferior materials, precision deviation and easy deformation and wear have long restricted the quality upgrading of high-end manufacturing. With years of in-depth experience in ultra-precision granite components, UNPARALLELED Group relies on exclusive high-grade materials, top-tier intelligent manufacturing capabilities, strict inspection systems and mature craftsmanship to develop and produce high-quality wear-resistant granite bases. We break industry precision barriers with solid quality and redefine new standards for global precision granite base manufacturing.
UNPARALLELED granite bases maintain a leading position in the global industry, primarily thanks to our exclusive customized UNPARALLELED® original black granite material. Featuring a high density of nearly 3100kg/m³, the material delivers far better physical stability, compression resistance, wear resistance and deformation resistance than ordinary marble and even outperforms European and American imported black granite. It effectively eliminates precision deviation and structural deformation caused by material fatigue, friction loss and temperature fluctuation during long-term high-frequency equipment operation. We firmly oppose the industry practice of shoddy substitution and always adhere to the customer commitment of "No cheating, No concealment, No misleading", providing global clients with pure, high-stability and wear-resistant ultra-precision granite benchmark substrates.
As the only enterprise in the industry certified with ISO9001, ISO45001, ISO14001 and CE full sets of authoritative qualifications, UNPARALLELED Group has obtained more than 20 international trademarks and patents in the EU, the United States, Southeast Asia and other developed regions through the China Council for the Promotion of International Trade. All products comply with mainstream global industrial standards, including German DIN series standards, American ASME and GGGP standards, Japanese JIS standards, British BS standards, Russian TOCT standards and Chinese GB standards. We achieve seamless alignment with global specifications, ensuring the compliance, stability and reliability of exported products and meeting the stringent procurement requirements of industrial customers worldwide.
Headquartered in Jinan, Shandong Province, close to Qingdao Port, the company enjoys convenient sea and land logistics to efficiently serve global customers. The group owns two standardized manufacturing factories covering a total area of 200,000 square meters, together with a 20,000-square-meter exclusive stone storage yard to ensure sufficient raw material reserves and stable production capacity. Equipped with four professional production lines for precision granite beds, we achieve a monthly output of 20,000 sets of 5000mm granite precision beds. We are recognized as the world's most efficient and highest-yield manufacturer of precision granite products, capable of handling both bulk orders and customized demands efficiently.
In terms of core processing capabilities, we have introduced four ultra-large Taiwan Nantou grinding machines, each valued at over 500,000 US dollars, supporting high-precision grinding of metal and non-metal precision platforms up to 6000mm in length. Equipped with self-developed heavy-duty CNC processing equipment and professional cranes, we support customized production of ultra-large-size products. The maximum processing capacity covers a single unit weight of 100 tons, a length of 20 meters, a width of 4000mm and a thickness of 1000mm, fully meeting the large-size and high-spec customization needs of global heavy industry and high-end precision equipment manufacturers.
To maximize and stabilize ultra-high product precision, we have built a 10,000-square-meter semiconductor-grade constant-temperature and constant-humidity dust-free workshop, replicating the production and assembly environment of high-end semiconductor equipment. The workshop floor is poured with military-grade ultra-hard concrete with a thickness of over 1000mm. A specialized shockproof trench with a width of 500mm and a depth of 2000mm surrounds the workshop, matched with silent travelling cranes. This design completely isolates external vibration interference and temperature and humidity fluctuations, providing a zero-interference and ultra-stable environment for precision assembly, calibration and final inspection of granite components.
Precision originates from rigorous testing. We always adhere to the core manufacturing philosophy: "If you cannot measure it, you cannot produce it". The company is fully equipped with world-class imported precision testing instruments, including German Mahr 0.5μm dial gauges, Mitutoyo micrometers, digital calipers, roughness testers, inductive micrometers, Swiss WYLER electronic levels, and British Renishaw laser interferometers. All testing equipment holds calibration certificates issued by Jinan and Shandong Metrology Institutes, with measurement data traceable to the National Metrology Institute, ensuring true, accurate and controllable precision for every product.
With long-term dedication to the ultra-precision industry, we maintain in-depth cooperation with top universities and national metrology institutes worldwide, including the National University of Singapore, Nanyang Technological University, Stockholm University, as well as authoritative institutions in the UK, France, the United States and Russia. We continuously upgrade measurement techniques and processing precision to sustain technological leadership. All staff receive professional metrology training and regularly study global testing standards including German DIN, American ASME, Japanese JIS, British BS, Russian TOCT and Chinese GB standards to fully comply with international production specifications. Our senior polishing workers boast more than 30 years of manual polishing experience, capable of achieving nanometer-level precision through micron-level manual control, known by clients as "walking electronic levels". Our sophisticated hand polishing craftsmanship delivers industry-leading precision performance.
Our ultra-precision wear-resistant granite bases and full series of granite measuring tools are widely applied and serve as essential core components for high-end ultra-precision industries. They are extensively used in semiconductor equipment, PCB drilling machines, coordinate measuring machines (CMM), precision testing instruments, precision CNC equipment, femtosecond/picosecond laser equipment, 2D image measuring instruments, contour measuring devices, AOI optical inspection equipment, industrial CT, XRAY equipment, linear motor platforms, perovskite coating machines, new energy lithium battery testing equipment and tool detection equipment. Meanwhile, granite surface plates, straight edges, square rulers, V-blocks and parallel blocks feature nanometer-level flatness and stable 1μm precision, serving as indispensable benchmark tools for global metrology inspection, equipment assembly and precision calibration. 
Benefiting from top-tier product quality, strict quality control and professional service concepts, UNPARALLELED has established long-term cooperative relationships with Fortune 500 enterprises including GE, Samsung, Apple and Oracle, as well as world-renowned industrial brands such as Bosch, Schunk, Rexroth, THK, HIWIN and MISUMI.
