tion. Tighten the draw bar until it stops, then loosen it 1/4-1/2 turn and turn the air<br />
valve to the “Clamped” position (adjusted for maximum clamping force). To reduce<br />
clamping force, loosen the draw bar or reduce the air pressure before adjusting.<br />
Air Collet Closers<br />
Model AC25 / AC100 / AC125 for the HA5C, and T5C<br />
The AC25 is a non thru-hole type closer that holds parts using air pressure, which<br />
provide up to 3000 pounds of draw force, depending on air pressure supplied. The<br />
unit provides .03” of longitudinal movement so diameter variations of up to .007” can<br />
be clamped securely without readjustment.<br />
The AC100 is a thru-hole type closer that holds parts using spring force, providing<br />
up to 10,000 pounds of draw force. The unit provides .025” of longitudinal<br />
movement so diameter variations of up to .006” can be clamped securely without<br />
readjustment. Set air pressure<br />
between 85 and 120 psi.<br />
The AC125 air collet closer has a<br />
5/16” thru-hole that will allow small<br />
diameter stock to extend out of the unit.<br />
The AC125 also has a large diameter<br />
counterbore in the drawtube that allows<br />
stock to pass through a standard 5C<br />
collet up to approximately 1.6” out the<br />
rear of the collet. This also allows the<br />
use of most standard collet stops. The<br />
AC125 uses air pressure to provide up<br />
to 12,000 lb. of draw force (adjustable<br />
through a customer supplied air<br />
pressure regulator). The drawtube travel<br />
0.060” allows the unit to securely clamp<br />
parts with up to .015” variation in<br />
diameter without readjustment.<br />
Manual Collet Closer Removal<br />
(Model AC25 / AC100 /<br />
AC125)<br />
Before installing the an air collet<br />
closer on the unit, you must first<br />
remove the manual collet closer<br />
assembly (Item B). Remove the<br />
top and bottom mounting bolts<br />
for the handle (Item A) and slide<br />
the handle off the collet closer<br />
assembly. Remove the collet<br />
closer, slide the collet closer<br />
assembly out the back of the<br />
spindle. Remove the flathead<br />
