Key Features
- High Dimensional Stability: Natural granite has extremely low thermal expansion, ensuring long-term geometric precision.
- Vibration Damping: Granite absorbs vibrations better than metal, improving measurement accuracy and machining quality.
- Corrosion & Wear Resistant: Unlike cast iron, granite does not rust and is highly wear-resistant.
- Custom Sizes Available: We manufacture extra-large granite structures up to 12000 × 3000 × 1000 mm. Lengths for spliced granite assemblies are virtually unlimited.
- Surface Flatness & Parallelism: Lapped to sub-micron precision according to international standards (DIN, GB, JIS, or ASME).
