Precision Granite Machine Components | ZHHIMG® High-Stability
In the world of ultra-precision manufacturing, we often focus on the “brain” of the machine—the sensors, the software, and the high-speed motors. Yet, the most sophisticated electronics are fundamentally limited by the material they rest upon. When you are operating in the realm of nanometers, the silent, unmoving base of your machine becomes the most critical component in the entire system. At ZHONGHUI Group (ZHHIMG®), we have spent decades perfecting the science of the “Zero Point,” ensuring that our precision granite components, like the high-stability beam shown here, provide the unwavering foundation that global leaders like Apple, Samsung, and Bosch rely on.

Granite Air Bearing
The core characteristics of granite air bearings can be summarized from three dimensions: material, performance, and application adaptability:
Material Property Advantages
- High rigidity & low thermal expansion coefficient: Granite has excellent physical stability, which reduces the impact of temperature changes on precision.
- Wear-resistant & low vibration: After precision machining of the stone surface, combined with the air film, operational vibration can be further reduced.
Enhanced Air Bearing Performance
- Contactless & wear-free: Air film support eliminates mechanical friction, resulting in an extremely long service life.
- Ultra-high precision: By combining the uniformity of the air film with the geometric accuracy of granite, motion errors can be controlled at the micrometer/nanometer level.
Application Adaptability Advantages
- Suitable for high-precision equipment: Ideal for scenarios with strict precision requirements, such as lithography machines and precision measuring instruments.
- Low maintenance cost: There are no mechanical wear parts; only clean compressed air needs to be ensured.

Granite Mechanical Components—Precision measuring instruments
Granite mechanical components, relying on the granite material, have advantages such as high hardness, stable physical and chemical properties, low thermal expansion coefficient (not prone to thermal deformation), and excellent shock resistance.Granite mechanical components are mainly used as core structural parts such as bases and worktables for precision equipment like coordinate measuring machines, high-precision machine tools, and semiconductor production equipment, serving to ensure the accuracy and stability of the equipment during operation. -
Granite Bridge—Granite Mechacnical Components
The granite bridge is one of the core supporting components in the precision industrial field.
Made from high-density granite, it leverages the material’s properties of low thermal expansion and contraction, deformation resistance, and vibration resistance. It is mainly used as the frame/datum structure for coordinate measuring machines, precision machining equipment, and optical inspection instruments, ensuring the stability and measurement/machining accuracy of the equipment during high-precision operations. -
