Dunham Tool manufactures high quality
5c air collet chucks, 2j air collet chucks, 16c air collet
chucks and 3j air collet chucks as well as many other sizes.
This Dunham air collet chuck is designed for use in both rotary and stationary
applications, and will mount to any American Standard, Camlock, Flat Face
style spindles or Rotary Tables with the use of a Dunham spindle mounting adapter.
Dunham Tool chucks, with a precision collet
closer and collet actuator, are commonly used as a lathe chuck,
as well as with cylindrical or surface grinders, rotary tables,
machining centers and other equipment. Dunham will provide
the spindle adapter to accommodate your workholding specification.
This air lathe chuck is designed for absolute concentricity
Dunham air collet chucks are designed
for secondary chucking, not for through work, and accept all
5c collets and Dunham expanding internal collets for I.D holding
from 1/4" to 6" diameters. Models are also available for 2j,
3j and 16c collets.
Adjustable concentricity screws
permit adjusting to 0.0005" TIR. Internal stops eliminate
length changes due to drawback. Foot or hand valves free hands
for efficient part handling. A special air union permits spindle
speeds to 3,500 rpm. Heat is not generated in the air collet
chucks due to the external mounting of an air union.
Collet sticking is eliminated
by a spring-loaded piston. Shop air pressure activates a large
piston, closing the collet. The piston is spring-loaded and
returns when air pressure is exhausted.
- Requires only 1 air line, either through
the spindle to the center chuck Rear Housing air port, or to the side air port
- Standard shop air operates
air collet chucks
- Power factor: 15 times the
pressure, i.e. at 100 psi line pressure exerts a pull force
of more than 1,500 lbs. on collet air chuck
- Simple face plate mounting
or special spindle mounts to suit customer requirements
- Built-in concentricity flange
permits adjusting concentricity to new standards of collet
accuracy improving TIR of all collets
- Collet gripping power can
be uniformly controlled by regulating air pressure
- Lightweight - air collet chucks
weighs approximately 9 lbs. No frictional heat is generated
by lathe chuck
