Which of the following is NOT a function of lubrication in machine tools?

• A. Reducing friction between moving parts
• B. Preventing overheating
• C. Cleaning oily surfaces
• D. Extending the life of machine components

Answer: (C)

Lubrication plays a crucial role in the operation and maintenance of machine tools, and understanding its functions helps in appreciating how machinery operates efficiently. Among its primary functions is the reduction of friction between moving parts. This decreased friction leads to smoother operation and helps prevent wear and tear on components. Another essential function of lubrication is the prevention of overheating. Proper lubrication ensures that heat generated by friction is dissipated, which is vital for maintaining optimal operating temperatures and preventing damage due to excessive heat. Extending the life of machine components is also a key benefit of effective lubrication. By reducing friction and controlling temperatures, lubrication helps to minimize wear and extends the usability of the parts, leading to a longer service life. However, cleaning oily surfaces is not a primary function of lubrication. While some lubricants may have cleaning properties, the main purpose of lubrication is not to clean; rather, it is to provide a protective and functional barrier between moving parts. Therefore, this option does not align with the primary roles of lubrication in machine tools.
