Automatic Chucks: |
Collets have limitations with workholding
that can be overcome with the right type of chuck. Here
we are offering a few different styles of chucks that
broaden your OmniTurn's usefulness.
Automation of the chuck:
These three chucks all rely on a draw tube actuator.
With the OmniTurn, we use a pneumatic draw tube. The
pneumatics and controls do not change when using the
automatic chuck. M12 and M13 still close and open the
chuck from the program. The operator station buttons
also work the same way. These chucks are easily
integrated with automatic loaders. With the GT-Jr and
with Hardinge attachments, a pneumatic draw tube type
collet closer is required to operate the chuck.
Chuck advantages:
Part variations don't affect a chuck like a collet. A
collet does not like part variations of more than a few
thousandths. If the holding diameter is over or under
size, the collet will not hold the part firmly, if at
all. The chuck jaws move perpendicularly to the
workpiece. The part can vary greatly and the chucking
will still work.
Hold dead lengths in Z even if the holding diameter
varies, unlike a collet that must move in Z to close the
chuck jaws closer parallel to one another. If the
holding diameter of a part varies by .004" in a collet,
the Z location will vary .012". With the chuck, there
will be no change in the part location.
Large jaw stroke makes loading easier: Great for
automation. The jaws open so much that it is possible to
load part with larger diameters and bury them behind the
jaws.
Huge holding force: With the pneumatic collet closer
yielding a pulling force of 1,400# at 80psi, the chucks
can grip with over 5,000#. This is easily regulated with
the pneumatics.
Machinable jaws make difficult work holding applications
easier to set up. By being able to machine the jaws, you
can now hold parts that are not round, require side
loading, or have to be machined eccentric.
The maximum RPM ratings shown are not possible with all
spindle nose configurations and spindle drive types. If
you require higher RPMs, please contact the factory for
application assistance. If you intend to do short cycle
work, also please contact the factory before purchasing. |
