In the world of ultra-precision engineering, scaling up usually means compromising on accuracy. Achieving sub-micron flatness on a small reference plate is one thing, but maintaining that same level of precision across a massive, 20-meter long gantry machine bed weighing dozens of tons is a completely different challenge.
At ZHONGHUI Group (ZHHIMG), we have broken these physical limitations. By blending heavy-duty industrial capability with state-of-the-art metrology, we provide global engineering teams with custom, large-scale precision components that other manufacturers simply cannot produce.
As the only manufacturer in our industry to simultaneously hold ISO 9001, ISO 45001, ISO 14001, and CE certifications, ZHHIMG has set the global standard for custom precision manufacturing.
1. Unmatched Scaling: Up to 100 Tons and 20 Meters in Length
Many suppliers are limited to standard catalog sizes. ZHHIMG, operating from our massive 200,000 square meter manufacturing facilities and a dedicated 20,000 square meter raw material yard, is built for extreme customization.
Our heavy-duty infrastructure and specialized overhead cranes allow us to handle single-block materials with incredible dimensions:
-
Weight Capacity: Handling and processing single-piece structures weighing up to 100 tons.
-
Dimensional Range: Capability to machine single blocks up to 20 meters in length, 4000mm in width, and 1000mm in thickness.
-
High-Volume Production: With four specialized production lines dedicated entirely to granite precision beds, we can produce up to 20,000 sets of 5000mm-class granite beds per month. This makes ZHHIMG the world’s fastest and highest-volume producer of precision granite by annual tonnage.
2. Advanced Machinery to Tackle Complex Geometries
To transform high-density ZHHIMG Black Granite (density approximately 3100 kg/m3) into complex machine bases, we invest in the world’s best machining equipment.
Our facilities house four ultra-large grinding machines from Nantex (Taiwan). Each of these machines represents an investment of over 500,000 USD and is capable of grinding both metal and non-metal platforms up to 6000mm in length to near-perfect flatness.
This heavy-duty machinery allows us to easily incorporate custom features directly into your granite bases, such as:
-
Precision T-slots and threaded inserts.
-
Highly accurate guide rail mounting surfaces.
-
Internal wire-routing channels and complex weight-reduction pockets.
-
Integrated air-bearing pathways.
3. A Multi-Material Portfolio for Advanced Engineering
While premium black granite remains our core strength, modern high-tech industries often require multi-material engineering solutions to meet specific weight, rigidity, or thermal properties. ZHHIMG is a true multi-material specialist, providing custom-engineered components in:
-
Precision Ceramics: Featuring ceramic components and ceramic precision measuring tools for ultra-wear resistance and extreme thermal stability.
-
Precision Metals: Providing high-precision CNC machining and custom metal castings.
-
Mineral Casting and UHPC (Ultra-High Performance Concrete): Offering excellent vibration-damping alternatives for complex machine beds.
-
Precision Glass: For specialized optical and inspection applications.
-
Carbon Fiber Precision Beams (Bridges): Delivering ultra-lightweight, high-stiffness structures for high-speed gantry systems.
4. Globally Certified Quality and Intellectual Property
We believe that true quality must be verifiable. ZHHIMG is highly unique in our sector for our absolute commitment to international regulatory and quality compliance.
-
Four-in-One Certification: We are the only manufacturer in our industry to be certified under ISO 9001 (Quality Management), ISO 45001 (Occupational Health & Safety), ISO 14001 (Environmental Management), and CE standards.
-
Global Trademark & Patent Protection: Working closely with the Trademark and Patent Office of the China Council for the Promotion of International Trade (CCPIT), we have registered over 20 international trademarks and patents across the European Union, the United States, Southeast Asia, and other developed regions.
This robust compliance framework ensures that when global Fortune 500 companies—such as GE, Apple, Samsung, Bosch, Rexroth, and Schunk Group—partner with us, they do so with absolute peace of mind regarding supply chain compliance, intellectual property safety, and product reliability.
5. Built on Integrity: “No Cheating, No Concealment, No Misleading”
At ZHHIMG, we stand firmly against the industry practice of using cheap, low-grade commercial marble to cut costs. We deliver only premium, certified materials processed under the strictest quality control guidelines.
From our highly-trained operators to our master hand-lappers (each with over 30 years of manual experience), our team is dedicated to bringing your custom engineering designs to life with unmatched precision.
