Abstract
A lathe or other rotating machine includes a chuck for holding a work piece or tool. The chuck is operated between grasping and releasing positions. A chuck guard is mounted on a housing of the rotating machine. The chuck guard has a transparent window and is mounted for pivoting movement between a position covering the chuck and a position exposing the chuck. A chuck guard extension with a window is attached at a front lower end of the chuck guard.
