Kitagawa NEW DKF Quick-Change Collet Chucks for Compact Envelopes & Machining Environments

First & Second Operation Collet Chuck
Designed with a fixed length actuation system that ensures the collet
is held stationary. Allowing the collet chuck to be used in bar feeding
operations and highly accurate second operations. DKF collet
chucks are suitable for collets which have a +/-0.5mm gripping range.

Fixed Length Collet
Workpiece remains in a fixed position during actuation, allowing for
precise z-axis positioning. A tapered sleeve is pushed forward,
compressing the collet and gripping the workpiece.

Problem Free Installation
Kitagawa NorthTech collet chucks are provided with mounting bolts and a
custom-machined drawtube connector allowing you to start using
the DKF collet chuck straight out of the box.

Quick & Easy Mounting
DKF collet chucks mount directly to the lathe spindle or use a
precision adaptor plate to ensure a consistent mounting without the
need for correction. The precision fit of the Klamp collet chuck enhances
the rigidity of the overall system. The need for adjustment is minimal,
meaning less machine down-time.

Long Service Life
All Kitagawa NorthTech collet chucks are case hardened, optimising the rigidity, strength and durability.

Short Body/Wide Range
DC Varibore collets allow for a compact body design maximising the lathe
work envelope. Gripping capacities of the series range from 4mm to 65mm.

Low-Profile Nose
DKF Series Collet Chucks have a small nose diameter for supierior
tool clearance.

Fully Sealed
No grease required to operate the collet chuck. O-ring seals are
incorporated within the design to prevent coolant and chip ingress.

High Speed
Direct mount design ensures high concentricity that is suitable for
higher speed operations that are not appropriate for conventional
3-jaw chuck due to the negative effects of centrifugal force.

Suitable for DC Varibore Collet Types
DKF collet chucks accept DC Varibore Collets that have the same
accuracy specification as spring collets whilst maintaining a gripping
range of +/- 0.5mm. Supplied with either smooth or serrated gripping
surface. Serrated collets are ideal for aggressive first operation gripping
of rough bar work.Vulcanized rubber between the hardened steel collet segments provides excellent protection against coolant and chip ingress. Counter boring and special profile shapes are available upon request.

Designed for Bar Pushers/Bar feeders
Kitagwa NorthTech Fixed-length DKF collet chucks are designed to work with bar loaders and bar feeders by not interfering with the process of the bar feeder action.
