Is it safe to stop the rotation of the chuck, spindle, or workpiece with your hands or fingers?

Stopping the rotation of the chuck, spindle, or workpiece with your hands or fingers is not safe due to the risk of serious injury. The equipment operates at significant speeds and can pose a danger of pinching or crushing injuries. Using hands or fingers in this manner does not offer sufficient control or safety, and the possibility of being caught in moving parts can result in severe consequences.

Instead, proper safety protocols dictate that any necessary stopping or adjustments should be made using designated controls or stop mechanisms, which are designed to halt the machinery safely. This ensures that the operator remains at a safe distance from moving parts and reduces the risk of accidents. Implementing these safety practices is essential in maintaining a safe working environment.
