Applied to equipment infrastructure, it can carry high-precision instruments, robotic arms, as well as guide rails, screw modules and linear motor modules. It can make larger semi-counterbore holes, through holes, steps and grooves according to equipment design needs;
The main functions of the granite equipment base include improving the stability and accuracy of the machine tool, reducing the impact of ambient temperature changes on the machine tool, and enhancing the earthquake resistance and anti-vibration performance.
1. Improve the stability and accuracy of machine tools
The granite base material is stable, shock-resistant and wear-resistant, which can significantly improve the stability and accuracy of the machine tool. The expansion coefficient of granite is similar to that of the machine tool body. It can deform the same as the machine tool body when the temperature changes, thereby reducing the deformation of the machine tool caused by temperature changes, thereby reducing positioning errors and ensuring machining accuracy.
2. Reduce the impact of ambient temperature changes on machine tools
The linear expansion coefficient of granite is only one-third that of ordinary metals, the thermal conductivity is also low, and it is less affected by temperature. When the ambient temperature changes, the deformation produced by granite is only one-tenth that of steel and one-third that of cast iron. This allows the granite base to reduce the deformation of the machine tool caused by temperature changes and ensure the processing accuracy of the machine tool. and stability.
3. Enhance seismic performance and anti-vibration performance
The internal damping coefficient of granite is 15 times larger than that of steel, and it has better anti-shock and shock-absorbing effects. Under the action of external forces, granite is not prone to elastic deformation and plastic deformation. It can maintain high accuracy under heavy loads and is not prone to deformation and burrs. It is suitable for use in high-precision measurement and processing equipment.
4. Applicable scenarios
Granite bases are usually suitable for high-precision machine tools and inspection equipment, such as CNC machine tools, high-precision grinders, wire cutting machine tools, optical inspection equipment, etc.
In summary, granite equipment bases have significant advantages in improving machine tool stability, reducing the impact of ambient temperature, and enhancing seismic performance, and are suitable for high-precision machine tool processing and optical inspection fields.
