What is the purpose of a brush or rag in metalworking?

• A. To polish surfaces for aesthetic purposes
• B. To remove swarf from metal
• C. To apply lubricants on metals
• D. To test for metal brittleness

Answer: (B)

In metalworking, using a brush or rag primarily serves the function of removing swarf, which refers to the small chips or shavings produced during cutting, grinding, or machining processes. Keeping surfaces clear of this debris is essential because swarf can interfere with subsequent machining operations, lead to tool wear, or even cause defects on the workpiece. By maintaining a clean working environment through the use of brushes or rags, machinists can ensure smoother operations and enhance the quality of the final product. This practice helps in providing better visibility of the work surface, allowing for more precise measurements and adjustments. The importance of removing swarf cannot be overstated, as it plays a crucial role in maintaining the efficiency and effectiveness of machining tasks.
