5. Usage
This product is a device to fix a work-piece when it is processed by the rotary table.
The handle closes the jaw manually and fixes a work-piece so that it does not move during
processing. The chuck opens the jaw after having processed it and remove a work-piece.

・
When replacing the top jaw, carefully clean the top jaw and the cross-key (key and
keyway) of base jaw. If not, it will cause an inadequate deflection accuracy.
5-1. Precautions during gripping work with chuck
・
When gripping a work with the
chuck, do not get fingers or hands
become caught. This could cause
crushed or cut fingers and hands.
5-2. Precautions during gripping work in irregular shape
・
If a work in an irregular shape is gripped the jaw may be broken. Consult our
company or the distributor if there is any concern.
・
Cast metal, pitched shape or taper shape cannot be gripped.
・
If the protrusion of the work is long, support it with a center or the steady rest.
If the protrusion is long the tip of the work turns, and this is dangerous as the
work will fly out.
