What is the safest way to remove chips from a lathe or milling machine?

Using a brush is the safest way to remove chips from a lathe or milling machine because it allows for controlled and careful removal of debris without the risk of it becoming airborne, which can happen with high-pressure air. This method minimizes the chance of chips being blown into the operator's face or eyes, thereby reducing the potential for injury.

Additionally, using a brush can help to dislodge chips that are stuck in tight spaces without the risk of direct hand contact with moving parts or sharp edges. It serves to keep the working area clean while promoting safety and visibility, which is essential for maintaining a safe working environment.

Employing tools like a vacuum cleaner can also be effective for chip removal, but it may not offer the same level of control and could potentially introduce other hazards depending on the machine's operation and the type of vacuum being used. Handling chips by hand, even with gloves, also poses risks, especially if there are sharp or hot materials involved. Therefore, using a brush is the most effective method in terms of safety and practicality.
