Application and Advantages of Marble/Granite Platform Gantry in High-Precision Measurement
High-Precision Measuring Tool: Marble/Granite Platform Gantry
The Marble/Granite platform gantry serves as the cornerstone of high-precision measurement and the stable foundation for automated equipment. Crafted from natural stone, it outperforms cast iron platforms in scenarios with strict precision requirements, leveraging the inherent properties of its material. In the automation sector (particularly in the semiconductor optical testing industry), Marble/Granite bases have become the preferred foundational structure for automated systems. Their exceptional precision and stability ensure seamless integration with components like guide rails, safeguarding the smooth operation of equipment while enhancing production efficiency and product quality in modern industrial applications.
Application Scenarios
- Serves as the inspection benchmark for instruments, precision tools, and mechanical components in high-precision measurement.
- Used for the calibration and dimensional verification of machine tools, ensuring that parts meet strict standards for dimensional tolerances and geometric accuracy.
Core Advantages
- Superior Precision: Far exceeding cast iron platforms, it meets the calibration requirements of precision machinery and equipment.
- Excellent Stability: Natural stone undergoes long-term aging treatment to eliminate internal stresses, ensuring zero deformation even after prolonged use.
- Strong Corrosion Resistance: Features acid resistance, alkali resistance, and magnetic interference resistance, requiring minimal maintenance and remaining unaffected by moisture or rust.
- Exceptional Wear Resistance: When the surface is impacted or scratched, it only produces shallow dents rather than raised burrs, safeguarding measurement integrity.
Good Thermal Stability: With an extremely low linear expansion coefficient, it maintains measurement precision across different temperature environments.
