Superior Performance for Demanding Industrial Applications
Drilled granite surface plates (also called granite inspection plates) represent the gold standard in precision measurement tools. Engineered from premium natural stone, these plates provide an exceptionally stable reference surface for:
- Precision instrument calibration
- Mechanical component inspection
- Quality control verification
- Laboratory measurement standards
- High-tolerance manufacturing processes
Unmatched Material Advantages
Our granite plates are manufactured from carefully selected stone that has undergone millions of years of natural aging, ensuring:
✔ Thermal Stability - Maintains dimensional accuracy despite temperature fluctuations
✔ Exceptional Hardness - Rockwell C60 hardness provides superior wear resistance
✔ Corrosion Resistance - Impervious to rust, acids, alkalis and oils
✔ Non-Magnetic Properties - Ideal for sensitive measurement applications
✔ Low Maintenance - Requires no protective coatings and resists dust accumulation
Precision Engineering for Critical Measurements
Each plate undergoes:
- CNC Machining - Computer-controlled drilling and shaping for perfect geometry
- Hand Lapping - Master craftsmen achieve micro-inch surface finishes
- Laser Verification - Certified flatness to international standards (ISO, DIN, JIS)
Specialized Features of Drilled Granite Plates
- Precision-Tapped Holes - Allow secure mounting of fixtures and accessories
- Optimized Weight Distribution - Maintains stability under heavy loads
- Vibration Dampening - Natural stone absorbs harmonic vibrations
- Custom Configurations - Available with grid patterns, T-slots, or special hole patterns
Industry Applications
• Aerospace component inspection
• Automotive quality control
• Semiconductor manufacturing
• Optical equipment calibration
• Precision tooling verification
Technical Tip: For maximum accuracy, allow plates to stabilize at room temperature for 24 hours before critical measurements.
