Chuck Jaw Installation

When installing the jaws on a scroll chuck, it is important to make sure they are installed correctly. Incorrect installation will result in jaws that do not converge evenly and are unable to securely clamp a workpiece.

To install chuck jaws:

1.Rotate the chuck key clockwise until you see the tip of the scroll-gear lead thread just begin to enter jaw guide #1.

2.Insert jaw #1 into jaw guide #1, and hold the jaw against the scroll-gear.

3.Rotate the chuck key clockwise one turn to engage the tip of the scroll-gear lead thread into the jaw. Pull the jaw; it should be locked into the jaw guide.

4.Install the remaining jaws in numerical order, in the same manner.

—If installed correctly, the jaws will converge evenly at the center of the chuck.

—If the jaws do not converge evenly, remove them. Make sure the numbers of the jaws and jaw guides match, then re-install the jaws and make sure each one engages with the scroll-gear lead thread during its first rotation.
