1. Granite Material Properties
Our granite machine components are machined from stress-relieved Class-A granite, ensuring near-zero porosity and natural vibration damping. Each block undergoes:
3-Step CNC Surface Grinding (Roughing, Semi-Finishing, Mirror Finish)
Laser Interferometry Calibration (Traceable to NIST Standards)
Non-Destructive Testing (Ultrasonic Flaw Detection)
2. Industrial Use Cases
Engineered for mission-critical applications:
CNC Machine Bases: Reduce thermal drift by 60% vs. steel
CMM Measuring Platforms: Achieve ANSI B89.3.7 compliance
Semiconductor Wafer Stages: 99.97% vibration isolation
Optical Alignment Systems: Microradian-level angular stability
3. Pain Point Solutions
By choosing our granite components:
↑ 30% Machining Accuracy through inherent dimensional stability
↓ 45% Maintenance Costs with non-corrosive granite surfaces
✓ 5-Year Warranty backed by AS9100D aerospace certification
