Granite/Marble components have been widely used in the manufacturing of precision instruments and measuring equipment, thanks to their excellent dimensional stability, high rigidity, and low coefficient of thermal expansion. However, during the service life of Granite/Marble components, certain issues may arise, which can impair the performance of the equipment. This article will discuss these issues and corresponding preventive methods.

I. Common Issues

1. Staining

During the manufacturing process or actual use, Granite/Marble components may become stained over time due to prolonged exposure to various chemicals or contaminants. These stains not only affect the appearance of the equipment but also alter the surface properties of the Granite/Marble components, thereby exerting adverse effects on their performance.

2. Cracking

Granite/Marble may crack under specific conditions, such as exposure to high temperatures or sudden impact. Cracks can weaken the structural stability of the equipment and compromise its measurement accuracy.

3. Deformation

Although Granite/Marble components are highly rigid, they can still deform when subjected to excessive external force or load. Deformation not only impairs the measurement accuracy of the equipment but also may cause damage to other components of the equipment.

II. Preventive Measures

1. Cleaning and Maintenance

To prevent staining, Granite/Marble components should be cleaned regularly using non-abrasive cleaners. Acidic or alkaline solutions should be avoided, as these can easily cause staining. If stains have already formed, they can be removed by using the poultice method (Note: A professional method for removing stone stains using adsorbent materials) or applying hydrogen peroxide.

2. Standardized Handling and Storage

Granite/Marble components should be handled with care (i.e., lifted and placed gently), and stored in a dry and clean environment. Avoid exposing them to direct sunlight or extreme temperatures, as this can lead to cracking. During transportation, protective measures must be taken for Granite/Marble components to prevent impact damage.

3. Structural Design Optimization

Optimizing the design can effectively prevent deformation and cracking:

• By adding support structures or adjusting the overall design of the equipment, the load can be distributed evenly, avoiding excessive stress on specific areas;

• Finite Element Analysis (FEA) technology can also be used to identify potential critical areas with stress concentration in advance, thereby optimizing the design in a targeted manner.

III. Conclusion

Granite/Marble components are core parts of high-precision measuring instruments and equipment, but their use and maintenance require extra caution to avoid various issues. Adhering to standardized maintenance procedures, handling rules, and storage requirements can effectively extend the service life of the equipment; meanwhile, optimizing the structural design based on specific needs can ensure the equipment delivers optimal performance. Therefore, it is essential to take necessary preventive measures to ensure the stable and efficient operation of the equipment, which in turn improves productivity.
