With the AC-125 pneumatic collet closer, collets can be clamped and unclamped with the flip of a lever.
The AC-125 provides up to 12,000 lb (53,379 N) of draw force, with 0.060" (1.5 mm) of travel, allowing part diameter variation of 0.015" (0.38 mm) without readjusting the collet. Its design is similar to the AC-25, but uses two pistons, which more than doubles the available draw force. A large internal spring is used for part release. The AC-125 can be tightened from the rear, and provides a 5/16" (8 mm) through-hole. Its compact size allows it to be used with all models of HA5Cs, and with the use of a small spacer, it can be operated vertically. Clamping force is varied by regulating air pressure supplied to the unit. The AC-125 air collet closer can be used with all types of 5C collets, including step collets. Includes one closer for each head on multi-head units.
