Precision Granite Rotary Base Plate
The ZHHIMG® Precision Granite Rotary Base Plate is a high-accuracy circular granite platform engineered for demanding ultra-precision applications. Manufactured from proprietary ZHHIMG® Black Granite with a density of approximately 3100 kg/m³, this rotary base delivers exceptional structural rigidity, vibration damping, and long-term dimensional stability.
Designed for integration into rotary stages, precision positioning systems, semiconductor equipment, and metrology instruments, this granite plate provides a thermally stable and non-magnetic foundation where micron-level or sub-micron performance is required.
Unlike low-cost marble substitutes sometimes used in the market, this component is produced from true high-density granite specifically selected for advanced precision engineering.

In high-end industrial environments, base material directly influences accuracy, repeatability, and system life.
Compared with cast iron or steel structures, precision granite offers:
• Superior vibration damping performance
• Minimal internal stress and no deformation over time
• Excellent thermal stability under controlled environments
• Corrosion resistance and non-magnetic properties
• Long-term geometric stability without aging distortion
Granite’s crystalline structure naturally absorbs micro-vibration generated by motors, air bearings, and dynamic motion systems. This is critical for semiconductor inspection systems, optical metrology platforms, and ultra-precision machining equipment.
ZHHIMG® Black Granite demonstrates higher density and better physical performance than many European or American granite materials, ensuring superior stiffness and load-bearing capability.
We use various techniques during this process:
● Optical measurements with autocollimators
● Laser interferometers and laser trackers
● Electronic inclination levels (precision spirit levels)
