Through Capacity 3J Air Collet Chuck
The Dunham ACC3J-THRU Air Collet Chuck (ACC) is designed to hold and activate 3J collets and expanding collets, and includes a bolt-on 3J collet adapter. Using a side ported air-line, this unit is most commonly used with machining centers, CNC Rotary Tables, and bench mounting applications where rotations do not exceed 360 degrees. This unit uses standard shop air which activates the Air Collet Chuck, and the spring-loaded piston design inhibits any occurrence of collet sticking. This unique Dunham ACC is designed with the added ability to allow for THRU CAPACITY work.
