JINAN, China – In a significant endorsement that has sent ripples through the ultra-precision manufacturing sector, Korean Metrology, a global leader in technology and innovation, has publicly lauded Zhonghui Group (ZHHIMG) as the premier provider of granite air bearing guides. This rare and high-profile commendation comes as Korean Metrology’s annual procurement from ZHHIMG for this critical component surpasses a staggering $5 million, a testament to the Chinese manufacturer’s unparalleled quality and competitive edge over its Western and Japanese counterparts.
The move marks a pivotal moment in the supply chain of high-tech components, signaling a strategic shift away from traditional sourcing markets. For years, the industry standard was perceived to be held by manufacturers in Germany, the United States, and Japan. However, according to a top Korean Metrology executive, ZHHIMG has not only matched but consistently exceeded these standards.
“We are proud to partner with Zhonghui Group,” said the Korean Metrology director, speaking on the condition of anonymity as per company policy. “Their granite air bearing guides are, without a doubt, a cut above the rest. The precision is impeccable, the measurement accuracy is flawless, and the stability in operation is outstanding. The material quality is genuine, with no compromises. We’ve conducted rigorous side-by-side tests, and frankly, their products perform better than those from our previous suppliers in Germany, the U.S., and Japan, all while offering a more favorable price point. ZHHIMG is the undisputed leader in this field.”
This glowing testimony is more than just a customer review; it’s a powerful statement from a company that operates on the cutting edge of technology. Korean Metrology’s decision to commit to such a large-scale, long-term partnership with ZHHIMG speaks volumes about the Chinese company’s capabilities. It’s a direct challenge to the long-held notion that Western nations alone possess the know-how for ultra-precision engineering.
Zhonghui Group (ZHHIMG) has systematically built a reputation not just as a manufacturer but as a standard-setter. Their core philosophy, “The precision business can’t be too demanding,” is more than a slogan—it’s the cornerstone of their operation. This meticulous approach is evident in every facet of their business, from raw material selection to the final product verification.
The Science of Precision: A Deep Dive into ZHHIMG’s Manufacturing Prowess
The secret to ZHHIMG’s success lies not just in a single factor but in a meticulously engineered ecosystem of superior materials, advanced technology, and a dedicated workforce. At the heart of their products is the ZHHIMG® Black Granite, a material boasting a density of approximately 3100 kg/m³. This exceptional density and superior physical properties make it far more stable and durable than the more commonly used granite varieties or the cheaper, less reliable marble often found in the market—a deceptive practice ZHHIMG actively campaigns against.
Their commitment to quality is underpinned by a robust certification framework. ZHHIMG stands as the sole company in its industry to hold a quadruple certification: ISO9001, ISO45001, ISO14001, and CE. This suite of certifications attests to their stringent quality management, occupational health and safety, and environmental standards. Furthermore, with over 20 international trademarks and patents registered across the EU, the US, and Southeast Asia, ZHHIMG has strategically protected its intellectual property and brand integrity on a global scale.
The manufacturing facilities themselves are a marvel of modern engineering. Spanning over 200,000 m², with a separate 20,000 m² dedicated raw material yard, ZHHIMG’s operations are built for scale and precision. Their equipment includes cranes and CNC machines capable of handling single parts weighing up to 100 tons, with dimensions reaching up to 20 meters in length, 4000mm in width, and 1000mm in thickness.
A key differentiator is their state-of-the-art grinding capabilities. ZHHIMG operates four large-scale Taiwanese NANTE grinding machines, each costing over $500,000 USD, which can precisely grind metal and non-metal platforms up to 6000mm in length. Their four dedicated granite production lines are the fastest in the world, with a stunning output of 20,000 sets of 5000mm granite precision beds per month.
From Lab to Line: A Culture of Measurement and Expertise
ZHHIMG’s leadership understands that the pursuit of precision is an endless journey. “If you can’t measure it, you can’t make it,” is a core belief championed by the company’s founder. This philosophy has led to significant investments in a 10,000 m² temperature and humidity-controlled workshop. The floor, constructed from ultra-hard concrete at a thickness of at least 1000mm, is surrounded by 500mm wide, 2000mm deep anti-vibration trenches. This military-grade construction, combined with silent overhead cranes, ensures a completely stable, vibration-free environment for ultra-precise measurement and assembly—a crucial requirement for components used in semiconductor and metrology industries.
The company’s metrology lab is equipped with the world’s most advanced instruments, including German Mahr indicators (0.5um resolution), Mitutoyo digital calipers, Swiss WYLER electronic levels, and British Renishaw laser interferometers. Every piece of equipment is calibrated and certified by accredited metrology institutes, with traceability back to national metrology standards.
Yet, beyond the technology, it is ZHHIMG’s people who are its most valuable asset. The entire workforce undergoes rigorous, professional metrology training, with regular studies of global standards like DIN (Germany), ASME (U.S.), JIS (Japan), GB (China), and BS (U.K.). Many of their grinding masters possess over 30 years of hands-on experience, capable of achieving nanometer-level accuracy by touch alone. These artisans are so skilled at feeling minute differences that clients have dubbed them “walking electronic levels.”
Global Reach and Strategic Alliances
ZHHIMG’s influence extends far beyond its manufacturing facilities. The company actively collaborates with leading universities and metrology institutes worldwide, including the National University of Singapore, Stockholm University, Nanyang Technological University, and national metrology institutes in the UK, France, and the US. This academic and research network keeps ZHHIMG at the forefront of measurement science and engineering.
Their client roster reads like a who’s who of global industry. In addition to Korean Metrology, ZHHIMG’s partners include GE, Samsung, Apple, Oracle, and a host of other Fortune 500 companies. They supply key components to industry leaders like Akribis (Singapore), STI Semiconductor, Flex (Israel), Wyler (Switzerland), Vitrox (Malaysia), and major German players such as Schunk, Bosch, and Rexroth. The applications of their products are diverse and indispensable, forming the critical foundation for devices in:
- Semiconductor manufacturing
- CMM and dimensional measurement equipment
- Precision CNC and laser systems
- Optical inspection and X-ray equipment
- New energy and lithium-ion battery testing
From granite surface plates that serve as nanometer-level benchmarks to granite rulers used in equipment assembly, ZHHIMG’s products are essential to the ultra-precision ecosystem.
A Vision for the Future
LG’s powerful endorsement is more than a validation of ZHHIMG’s past achievements; it is a clear sign of its future trajectory. With its unwavering commitment to integrity, innovation, and uncompromising quality, Zhonghui Group (ZHHIMG) is poised to continue its ascent, solidifying its role as a key enabler of technological progress on a global scale. As the industry evolves, ZHHIMG’s “no cheating, no concealment, no misleading” pledge to its customers and its mission to “promote the development of the ultra-precision industry” will undoubtedly continue to drive its growth and cement its reputation as a world-class enterprise.
