AC-100 Air Collet Closer

High-torque closer with 1.06" through-hole

With the AC-100 pneumatic collet closer, collets can be clamped and unclamped with the flip of a lever.

The AC-100 uses spring force for part clamping, and air pressure for release. It will retain full part clamping even if air pressure is removed. The AC-100 provides a 1.06" (27 mm) diameter through-hole, and collets are easily tightened from the rear. It provides up to 10,000 lb (44,482 N) of draw force, with 0.025" (0.64 mm) travel, and can be used for drilling and milling in most applications. The 0.025" (0.64 mm) travel allows for a part diameter variation of 0.006" (0.15 mm) without the need to readjust the collet. Due to its long rearward length, the AC-100 cannot be used vertically, and is not recommended for tilting HA5Cs. Also, some consideration must be given to clearances when using the AC-100 parallel to the Y axis, as its length may collide with the Z-axis way cover. Includes one closer for each head on multi-head units.
