A vacuum table works by creating a vacuum environment to generate suction, which then holds objects in place. The process is as follows:

• Vacuum extraction: When the vacuum pump starts, it extracts air from the surface of the table, reducing the air pressure in that area. As the pressure decreases, air molecules become less dense, creating a pressure difference between the object and the table surface.
• Suction force: The pressure difference creates an inward suction force that is strong enough to secure the object on the table.
• Stability maintenance: After the object is secured, the vacuum pump continues to maintain the pressure, ensuring the suction force is strong enough to keep the object stable.

The core principle of vacuum tables remains consistent. They can be classified according to specific applications, such as printer vacuum tables, laser engraving machine vacuum tables, and can also be categorized based on additional functions, such as air-floating vacuum tables and heated vacuum tables.
