In the ultra-precision industry, precision is the lifeline of products. Behind this precision, there are not only world-class processing equipment and strict quality control systems, but also a group of craftsmen who adhere to ingenuity and possess exquisite skills. In the production workshops of UNPARALLELED Group (UNPARALLELED®), there is such a group of grinding masters. With more than 30 years of hand grinding experience, they have developed a "micron-level touch", capable of accurately controlling the strength and precision of each grinding operation. They are affectionately called "walking electronic levels" by cooperative customers. Behind this praise lies the persistence of craftsmen and UNPARALLELED®'s ultimate pursuit of the ultra-precision industry. 
As a benchmark enterprise in the ultra-precision industry, UNPARALLELED® is the only professional manufacturer in the industry that holds multiple authoritative certifications including ISO9001, ISO45001, ISO14001 and CE. It has more than 20 international trademarks and patents registered in developed countries such as the European Union, the United States and Southeast Asia, and has long been synonymous with industry standards. The company has been deeply engaged in the R&D and production of various ultra-precision products such as precision granite, precision ceramics and precision metals, and has always adhered to the quality policy of "It is never too demanding for the precision business". Every link, from material selection, equipment investment to talent training, strives for perfection.
Thirty Years of Polishing, Forging a "Divine Touch" at the Micron Level
In the constant temperature and humidity dust-free workshop of UNPARALLELED®, the figures of the grinding masters are particularly eye-catching. This is an exclusive workshop specially built for the assembly of granite components. The floor is poured with super-hard concrete with a thickness of not less than 1000mm. Shockproof trenches with a width of 500mm and a depth of 2000mm are set around the workshop, and silent cranes run slowly, creating an extreme environment with stability and no vibration for product processing. The grinding tools in the masters' hands seem to come alive under their control, and each grinding and polishing operation is accurate to the micron level.
"Most of our grinding masters have more than 30 years of hand grinding experience. Their touch is honed through countless days and nights of practice and accumulation," introduced the company's person in charge. "When grinding products to ensure precision, they can accurately judge how many microns have been ground off with one grind. This kind of touch cannot be completely replaced by any precision instrument." It is this unique touch that enables the masters to adjust the grinding strength and angle in time during the processing, make up for the slight deviations in equipment processing, control the product precision to the nanometer level, and ensure that every product leaving the factory meets strict industry standards.
To develop this "divine touch", the masters have made unimaginable efforts. They not only need to be proficient in the use skills of various grinding tools, but also systematically learn various national testing and metrology standards, including more than ten international and domestic standards such as German DIN standards (DIN876, DIN875, DIN650, etc.), American GGGP-463C-78 standard, ASME standard, Japanese JIS standard and Chinese GB standard. The company organizes regular training every year, inviting industry experts and professionals from metrology institutes to give lectures, so that the masters can keep abreast of the latest technologies and standards and continuously improve their skills. After decades of accumulation, they are not only proficient in the grinding processes of various ultra-precision products, but also have an in-depth understanding of the physical properties of different materials. Whether it is UNPARALLELED® black granite with a density of approximately 3100kg/m³, or precision ceramics and metals, they can accurately control the grinding precision to make every product extremely perfect.
Strict Standards Escort, Ingenuity Skills Further Upgraded
"Without good equipment, it is impossible to produce good products; if you cannot measure it, you cannot produce it." This is the philosophy that the founder of UNPARALLELED® has always adhered to. To provide strong support for the masters' ingenuity and skills, the company has invested heavily in introducing world-class processing and testing equipment, building an industry-leading production and testing system.
In the production link, the company has two factories with a total area of 200,000 square meters, as well as a special stone storage site of about 20,000 square meters. It is equipped with world-class cranes and CNC equipment, capable of processing super-large products with a single weight of 100 tons, a length of 20 meters, a width of 4000mm and a thickness of 1000mm. Among them, 4 sets of Taiwan Nanthe super-large grinders, each costing more than 500,000 US dollars, can grind metal and non-metal precision platforms with a length of 6000mm. The company produces 20,000 sets of 5000mm granite precision machine beds every month, making it the world's fastest precision granite manufacturer in terms of processing speed and annual stone tonnage output. These advanced equipment provide a solid foundation for the masters' hand grinding, making extreme precision possible.
In the testing link, the company is equipped with a series of world-class testing equipment including German Mahr micrometer (0.5um), mitutoyo micrometer, Mitutoyo digital caliper, Swiss WYLER electronic level, British Renishaw laser interferometer, etc. All equipment holds calibration certificates issued by Jinan Institute of Metrology and Shandong Institute of Metrology, and the product calibration instruments can be traced back to the National Institute of Metrology. At the same time, the company has established in-depth cooperation with world-renowned universities and metrology institutes such as the National University of Singapore, Stockholm University in Sweden, the National Physical Laboratory of the United Kingdom, and the National Institute of Standards and Technology of the United States, continuously exploring more accurate and advanced measurement methods to escort product precision.
"Our masters not only have exquisite skills, but also a rigorous attitude," said the person in charge of the company's quality control department. "After each product is manually ground, it will go through multiple strict testing procedures to ensure that the product precision meets customer requirements. The masters' touch is also continuously optimized through repeated testing and calibration, forming a triple guarantee system of 'skills + equipment + testing'."
Integrity-Based, Winning Customer Trust with Ingenuity
"No cheating, no concealment, no misleading" is UNPARALLELED®'s commitment to every customer, and it is also the professional principle adhered to by the masters. In the ultra-precision product market, some small manufacturers shoddy products by using cheap marble to pass off as granite in order to reduce costs, which has seriously damaged the industry reputation. However, UNPARALLELED® has always insisted on using self-developed UNPARALLELED® black granite, which has high density, good stability and superior physical properties, far exceeding European and American black granite, and is by no means comparable to ordinary marble. During the processing, the masters also always adhere to the quality bottom line, never perfunctory, and every product embodies their ingenuity and responsibility.
It is this pursuit of quality and adherence to integrity that have won UNPARALLELED® recognition and trust from customers around the world. Customers from various fields such as semiconductors, PCB circuit boards, and CMM equipment have spoken highly of the precision and quality of the products after cooperating with UNPARALLELED®, and the exquisite skills of the grinding masters have left a deep impression on them. "Our products have extremely high precision requirements, and even the slightest deviation may affect the normal operation of the equipment. The masters of UNPARALLELED® have solved many precision problems for us with their 'divine touch'. It is well-deserved to call them 'walking electronic levels'," commented a long-term cooperative semiconductor equipment customer.
Inheritance of Ingenuity, Boosting the Development of the Ultra-Precision Industry
"Dare to be the first; have the courage to innovate" is the enterprise spirit of UNPARALLELED®, and this spirit is also perfectly reflected in the grinding masters. While adhering to traditional hand grinding techniques, the masters also actively learn new technologies and methods, organically combining hand craftsmanship with advanced equipment, continuously innovating grinding processes, and improving production efficiency and product precision. The company also attaches great importance to talent training, establishing a sound mentoring inheritance mechanism, allowing young employees to inherit ingenuity and skills and accumulate practical experience under the guidance of veteran masters, injecting fresh blood into the sustainable development of the enterprise.
"Our mission is to promote the development of the ultra-precision industry; our vision is to become a world-class enterprise trusted and loved by the public," said the company's person in charge. "The 'micron-level touch' of the grinding masters is a valuable asset of the enterprise and an important support for us to realize our vision.
