Precision Granite Machine Base

1. Superior Material Performance

•    Made from ZHHIMG® high-density black granite

•    Density ≈ 3100 kg/m³, significantly higher than conventional granite

•    Excellent thermal stability and minimal thermal expansion

•    Outstanding natural vibration damping, ideal for precision equipment

Many low-cost suppliers use marble or inferior stone under the name of granite. ZHHIMG strictly rejects such practices.
Material authenticity is guaranteed.

2. Ultra-Precision Manufacturing Capability

•    CNC machining combined with experienced manual lapping

•    Flatness, parallelism, and squareness controlled to micron or sub-micron levels

•    Threaded inserts, precision mounting holes, and interface surfaces processed in one integrated workflow

•    Suitable for large, heavy, and complex structures

Each granite base is manufactured in a constant temperature & humidity environment, ensuring stable geometry throughout the production process.

3. World-Class Metrology Assurance

All ZHHIMG granite bases are inspected using advanced measurement systems, including:

•    Laser interferometers

•    Electronic levels

•    High-resolution dial indicators and inductive probes

Measurement traceability is certified and linked to national metrology institutes, ensuring confidence in every delivered component.
