Precision Granite Machine Base / Gantry Structure
When precision reaches the micron—or even nanometer—level, traditional materials begin to fail. That’s where the ZHHIMG® Precision Granite Machine Base stands apart.
Engineered from ultra-high-density black granite, this gantry structure delivers unmatched thermal stability, vibration damping, and long-term geometric accuracy. It is not just a base—it is the foundation of ultra-precision systems.
Whether used in semiconductor inspection, laser machining, or coordinate measurement, this structure ensures your machine performs exactly as designed—day after day.

Superior Material Performance
Unlike cast iron or steel:
• No internal stress deformation
• No rust or corrosion
• Minimal thermal distortion
Granite maintains long-term stability without aging drift
Exceptional Vibration Damping
Granite naturally absorbs micro-vibrations:
• Improves machining accuracy
• Enhances optical measurement stability
• Critical for semiconductor and laser systems
Ultra-Precision Machining Capability
• Hand-lapped surfaces by 30+ year experts
• Micron-level tactile control
• Multi-reference surface alignment
Custom Engineering Flexibility
Every structure can be:
• Fully customized (size, hole pattern, assembly interface)
• Integrated with air bearings, linear guides, motors
• Designed for specific machine architectures
Cleanroom & High-End Application Ready
• Non-magnetic
• Non-conductive
• Suitable for cleanroom environments
We use various techniques during this process:
● Optical measurements with autocollimators
● Laser interferometers and laser trackers
● Electronic inclination levels (precision spirit levels)

Q1: Why use a granite machine base instead of cast iron?
Granite offers better vibration damping, no internal stress, and superior thermal stability, making it ideal for ultra-precision applications.
Q2: Can this granite structure be customized?
Yes. All dimensions, hole patterns, inserts, and assembly interfaces can be fully customized according to your drawings.
Q3: What level of accuracy can you achieve?
Flatness can reach micron to nanometer level, depending on size and application requirements.
Q4: How do you ensure measurement accuracy?
All products are inspected using:
- Laser interferometers
- Electronic levels
- Certified metrology instruments
Traceable to national standards.
Q5: Is it suitable for semiconductor equipment?
Absolutely. The material properties and cleanroom compatibility make it ideal for semiconductor and optical systems.
