Granite tables are an essential tool for precision assembly devices such as coordinate measuring machines, surface plate layout machines, and optical comparators. They are durable, resist wear, and are known for their stability and flatness. A granite table can last for many years if you use and maintain it correctly. In this article, we will discuss how to use and maintain granite tables for precision assembly devices.
1. Proper installation
The first step in using a granite table is to install it correctly. Make sure that the table is placed on a stable and level surface. It is advisable to place the table on a vibration dampening material such as cork or foam to reduce mechanical shocks. It is also crucial to align the table with the device you are using it with.
2. Cleaning
Regular cleaning of the granite table is necessary to maintain its accuracy and flatness. Clean the table after each use with a soft cloth or brush and a mild detergent. Do not use abrasive cleaners or metal scrapers that can damage the surface. Also, avoid wiping the table with dirty rags or towels as they can scratch the surface.
3. Avoid heavy loads
Granite tables are sturdy and can support heavy loads, but it is essential to avoid exceeding the weight limit specified in the manufacturer's instructions. Overloading the table can cause the surface to bow or warp, affecting its accuracy and flatness.
4. Use cover plates
When not in use, cover the granite table with a protective plate. These plates help keep the surface clean, reduce the amount of dirt and debris that can clog the table's surface, and protect the surface from accidental damage.
5. Leveling
Periodic leveling of the granite table is crucial to maintain its precision. Use a precise level to check the table's flatness, adjust the leveling feet if necessary. It is recommended to check the leveling at least once a year.
6. Prevent rust
Granite is not susceptible to rust, but the metal parts around the table, such as the leveling feet or the surrounding frame, can rust and corrode. Regularly clean and lubricate these parts to prevent rusting.
7. Hire a professional to repair damage.
If your granite table is damaged, do not try to repair it yourself. Contact the manufacturer or a qualified professional to repair the damage. Attempting to repair the damage yourself can cause additional problems and may void the manufacturer's warranty.
Conclusion
A granite table is an essential tool for precision assembly devices. With proper use and maintenance, a granite table can provide accurate and reliable results for many years. Regular cleaning, avoidance of heavy loads, use of cover plates, periodic leveling, and preventing rust can ensure the stability and accuracy of your granite table. In case of damage, always contact a qualified professional for repair.
