Selecting The Correct Type Of Chuck.
Scroll Type Manual
Chuck (Manual Actuated Self-Centering - available in 2-jaw, 2-3
jaw, 3-jaw, 4-jaw, and 6-jaw models)
A manual type chuck is
actuated by using a t-handle wrench inserted into the access
holes on the outside diameter of the chuck. When the
t-handle wrench is inserted into the actuating hole and
turned clockwise it turns an internal scroll. The
actuation of the scroll in turn causes the jaws to move
simultaneously with exactly the same amount of movement toward
center. If the t-wrench is turned counter clockwise the
jaws move outward toward the outside of the chuck. The
manual chuck may be equipped with solid one piece jaws or 2
piece jaws with a removable top jaw.
Independent Jaw Chucks (Manual Actuated Not Self-Centering -
available with 4-jaws)
An independent jaw chuck is designed
with 4 jaws which may be moved independently of on another.
A t-handle wrench is used to actuate a screw on each jaw
independently. When the t-wrench in inserted into the end
of a jaw screw and turned clockwise the jaw moves to the
center of the chuck. These chucks may be used to center an
irregular shaped work part or to position a work part off center
by choice. Independent chuck are available with
solid one piece jaws or 2 piece jaws with a removable top jaw.
Combination Jaw Chucks (Manually actuated)
A combination chuck combines
the scroll self-centering action of a scroll chuck with the
independent jaw movement of an independent jaw chuck. This
chuck may be used as a scroll chuck and move all the jaws
simultaneously or one jaw at a time. Combination chucks
are available with 2 piece jaws with a removable top jaw.
