Amputations

An employee was changing out a standard chuck and installing a collet chuck on a small twin spindle lathe. While attempting to take off the first chuck, the employee stepped on the foot pedal, which actuates the hydraulic draw tube and separates the chuck from the face plate. He placed his fingers between the chuck and face plate and attempted to unthread the chuck from the draw tube. While he was unthreading the chuck, the lathe was activated via the foot pedal. The chuck then drew back toward the face plate, crushing his fingertips. His left middle, ring, and pinky fingertips were amputated.
