What is the reason for cleaning and lightly oiling milling machine tables?

To maintain a clean work environment
To prevent rusting and loss of accuracy
To enhance the aesthetic look of the machine
To improve thermal efficiency

The correct answer is: To prevent rusting and loss of accuracy

Cleaning and lightly oiling milling machine tables serves the crucial purpose of preventing rusting and maintaining accuracy. Milling machines are often used in environments where moisture and contaminants can lead to corrosion on steel surfaces. Rust can create uneven surfaces, which in turn can cause inaccuracies during milling operations. By regularly cleaning the tables, you remove debris and particles that could scratch or mar the surface. Then, applying a light coat of oil provides a protective barrier against moisture, significantly reducing the likelihood of rust formation. This practice not only helps in maintaining the machine's physical integrity but also ensures that workpieces maintain the precision necessary for effective machining. Other options, such as maintaining a clean work environment, enhancing aesthetics, or improving thermal efficiency, may offer some benefits but are secondary to the primary goal of preserving the machine’s functionality and ensuring precise operations.
