Product Overview
We specialize in manufacturing ultra-stable granite structural components for three-axis motion systems. As granite machining experts, we deliver:
- Granite Machine Bases
- Granite Cross Beams
- Granite Support Columns
Note: We provide structural granite components only – motion systems require third-party drive integration.
Why Granite?
Our natural granite components (Type G350/G650) offer unmatched stability:
- Thermal Neutrality: 0.003 mm/m·°C expansion coefficient (1/30th of steel)
- Vibration Absorption: Q-factor <100 (10x better than aluminum alloys)
- Micro-deformation Resistance: Young’s modulus 60-100 GPa
- Wear-free Operation: Mohs 6-7 hardness surface
