Inner and outer diameter chuck for a laser cutting/engraving rotary fixture

A laser cutting/engraving rotary fixture comprising:

• opposing master and slave spindles rotatable about a spindle axis of rotation mounted to a frame;
• means for moving the slave spindle axially along the spindle axis of rotation relative to the master spindle;
• means operatively associated with the moving means for releasably securing the slave spindle at a select axial distance from the master spindle along the spindle axis of rotation;
• a drive mechanism operatively associated with the master spindle;
• and
• a chuck operatively associated with each of the master and slave spindles, the chuck comprising:
• a chuck plate having a chuck plate axis of rotation;
• and
• at least two mount brackets spaced symmetrically radially with respect to one another about the chuck plate axis of rotation, each mount bracket comprising an inclined contact surface, each mount bracket being rotatably attached to chuck plate about a mount bracket axis of rotation, whereby the inclined contact surface can be selectively rotated between a first position within the inclined contact surface inclined toward the chuck plate axis of rotation and a second select position with the inclined contact surface inclined away from the mount bracket axis of rotation.
