Introduction:

Granite/Marble parts are widely used in the manufacturing of precision instruments and measuring equipment due to their excellent dimensional stability, high stiffness, and low coefficient of thermal expansion. However, certain issues may arise during the use of Granite/Marble parts, which can affect the performance of the equipment. This article will discuss these problems and their prevention methods.

Problems:

1. Staining

Over time, Granite/Marble parts may become stained due to contact with various chemicals or substances during the manufacturing process or use. These stains not only affect the appearance of the equipment but also alter the surface properties of the Granite/Marble parts, thereby impacting their performance.

2. Cracking

Granite/Marble may crack under certain conditions, such as exposure to high temperatures or sudden impacts. Cracks can weaken the equipment's structure and compromise its accuracy.

3. Deformation

Although Granite/Marble parts are rigid, they can still deform when subjected to excessive external force or load. Deformation can affect the accuracy of the equipment and may even damage other components.

Prevention Measures:

1. Cleaning and Maintenance

To prevent staining, Granite/Marble parts should be cleaned regularly with non-abrasive cleaners. Avoid using acidic or alkaline solutions as they may cause staining. If stains have already appeared, a poultice or hydrogen peroxide can be used for removal.

2. Proper Handling and Storage

Granite/Marble parts should be handled with care and stored in a dry, clean environment. Avoid exposing them to direct sunlight or extreme temperatures to prevent cracking. During transportation, Granite/Marble parts must be properly protected to avoid any impact.

3. Design Improvements

Design improvements can be made to prevent deformation and cracking. By adding support structures or modifying the equipment's design, the load can be distributed evenly, thus avoiding excessive stress on specific areas. Additionally, finite element analysis (FEA) can be used to identify potential critical areas of stress concentration.

Conclusion:

Granite/Marble parts are indispensable in high-precision measuring instruments and equipment. However, they must be used and maintained properly to avoid problems. Following correct maintenance procedures, handling, and storage protocols can extend the equipment's service life. Design improvements can also be made according to specific needs to ensure the equipment performs at its best. It is crucial to take necessary precautions to prevent any issues, ensuring the equipment operates effectively and thereby improving productivity.
