5 Lathe Safety

The lathe is one of the machine shops’ most essential and versatile machines. It is used to shape various materials into precise components. However, like any powerful machine, the lathe poses inherent risks if not handled with caution and expertise. Therefore, understanding and adhering to a set of safety precautions is of utmost importance for the operators and those working in the area of these machines. The precautions listed below are not recommendations but strict rules to protect operators and prevent accidents. A safe and secure work environment can be established by diligently observing these rules. The following list has been adapted from the Canadian Center for Occupational Health and Safety (2018).

1. Wear proper PPE around lathes. This can include CSA-approved safety glasses. Steel toe boots, ear protection, and face shields.
2. Only trained and authorized personnel should operate the engine lathe. Ensure all operators have received proper training and certification for lathe operation and safety.
3. Remove entanglement hazards (e.g., loose clothing, jewelry, etc.). Tie back and confine long hair.
4. Keep the floor free from obstructions or slip hazards.
5. Ensure the lathe has an emergency stop button.
6. Follow job specifications for the speed, feed, and depth of cut for turning materials. Make sure all work runs true and centered.
7. Remove the chuck wrench immediately after adjusting the chuck.
8. Remove all tools, measuring instruments, and other objects from the saddle or lathe bed before starting the machine.
9. Shut off the power supply to the motor before mounting or removing accessories.
10. Stop the lathe and put the clutch in neutral before taking measurements.

Below is a 4-minute video discussing general lathe safety, how to install a chuck and emergency shutdown procedures. Be aware that all lathes are different and may have unique features. Always consult the operations manual provided by the manufacturer for detailed guidelines.
