on one chuck.
• Wide adaptor plates for all models available upon request.
• Clamping/unclamping of chuck during spindle rotation is possible.
• Less deformation of thin-walled components during clamping.
• High operating reliability due to a minimum number of parts.
• High axial positioning accuracy of the components by means
of push type collet system.

 CRS Collet Chuck
Short Series Power Collet Chuck for Bar Machining

Short Body/Wide Range

Varibore & rubber-flex collets allow for a compact body design
maximising the lathe work envelope. Gripping capacities of the series
range from 3 mm to 66mm

High Speed
Direct mount design ensures high concentricity suitable for higher
speed operations.

First Operation Collet Chuck

Klamp CRS collet chucks are suitable for collets which have a large
gripping range. Allowing the collet chuck to handle very rough and
unfinished bar, preparing it for a high accuracy second operation.

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

Klamp collet chucks are provided with mounting bolts and an optional
custom-machined drawtube connector, allowing you to start using the
Klamp collet chuck straight out of the box.

Quick & Easy Mounting

Klamp 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 Designed for Bar Pushers/
of the overall system. The need for adjustment is minimal, meaning less Barfeeders
machine downtime.

Long service life

All Klamp collet chucks are case hardened, optimising the rigidity,
strength and durability.
Fixed-length Klamp
collet chucks are designed
to work with bar loaders
and bar feeders by not
interfering with the
process of the bar feeder action.

 CRL Collet Chuck
Long Series Power Collet Chuck for Bar Machining

Long Body/Wide Range

High accuracy spring collets require a longer body design but Klamp collet
chuck design ensures that all external dimensions have been optimised to
provide maximum tool clearance. Gripping capacities of the series range
from 1.6mm to 80mm

High Speed
Direct mount design ensures high concentricity suitable for higher
speed operations.

First & Second Operation Collet Chuck

Klamp CRL collet chucks are suitable for spring, varibore and rubberflex
collets increasing its flexibility. Varibore and rubberflex collets allow rough,
unfinished bar to be machined in the first operation and spring collets can
be used for high accuracy in the second operation.

Versatile
Rubber-Flex collets, type DRFC 673 (173E equivalent) and DRFC 677 • Perfect sealing against coolant and swarf
(185E equivalent) are available in “Smooth” or “Full Grip” design.
“Smooth” collets are ideal for 2nd Operation work or sensitive workpieces • More surface area = higher torque transfer
with surfaces that should not be marked. “Full Grip” collets have wider • Coolant and temperature resistant up to 100° C
steel segments provide a higher rigidity. These double-serrated collets
have an increased clamping force and are especially designed to machine • Gentle surface clamping with parallel closing
bar material with wide clamping tolerances and high torque. of steel segments
Due to the unique design Rubber-Flex collets also increase the diameters
that your collet chuck can clamp. For example, a Q-CRL42 collet chuck
can clamp up to 45mm from the standard 42mm and for a Q-CRL60 collet
chuck can clamp up to 65mm from the standard 60mm using Rubber-Flex.

 DHP Collet Chuck
Pull Back Series Power Collet Chuck for Bar Machining

First Operation Collet Chuck

Klamp DHP collet chucks are suitable for collets which have a +/-0.5mm
gripping range. Allowing the collet chuck to handle rough and unfinished
bar, preparing it for a high accuracy second operation.

Pull Back Action

The Collet pulled into the chuck to close and pushed out to open
This action means that back stops cannot be provided and must be
used where accurate axial positioning is not important.

Problem Free Installation

Klamp collet chucks are provided with mounting bolts and a
custom-machined drawtube connector allowing you to start using
the Klamp collet chuck straight out of the box.

Quick & Easy Mounting

Klamp 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 Klamp collet chucks are case hardened, optimising the rigidity,
strength and durability.
Suitable for DC Varibore Collet Types

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 80mm.

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. Klamp DHF 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.

 KEM Expanding Mandrels
Power Expanding Mandrels for Lathes

Rigid and Accurate Workholding for Internal Diameters

Internal Clamping Offers Full Part Access
Allows for full access to the entire external profile of the workpiece so
all external diameters can be turned in a single operation, guaranteeing
perfect concentricity.

Quick & Easy Mounting

Klamp expanding mandrels 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.

High Accuracy & Rigidity

Pull-back design draws the workpiece securely against a part locator for
‘dual-contact’ rigidity.

Modular Design
All Mandrel models have a common flange configuration, enabling full
interchangeability with all back bodies.

Parallel Expansion for Optimum Accuracy

and Grip Force
The Klamp double-angle design provides parallel sleeve expansion, ensuring
full-length part contact and positive release when the part is unclamped.

Two Regular Sleeve Types Available Customised Systems Available

Standard Sleeves
Cost effective sleeves where the expander pin is outside the sleeve body, Dual sleeves (as shown above), extended length sleeves, 1/2 length
with either a 0.5mm or 0.8 gripping range (see pages 51-53 for more sleeves and larger diameter sizes are on the market with up to
detail), suitable for through bores and operated with a part locator. 635mm ID gripping for supporting a wide range of parts.

Flush sleeves

 KEM Expanding Mandrels
Manually Actuated Expanding Mandrels

Heavy Duty Gearing

The Klamp manually actuated mandrel (KEM-MA) provides a high gripping
force utilising the same standard Klamp Mandrel assemblies as the power
operated systems therefore giving you the ability to have an internal
gripping solution that can be rapidly deployed with whatever standard
workholding system your machine(s) has.

Two Regular Sleeve Types Available

Standard Sleeves Flush Sleeves

Cost effective sleeves where the expander pin is outside the sleeve body, Expander pin is inside/level with the sleeve body with either a 0.5mm or 0.8
with either a 0.5mm or 0.8 gripping range (see pages 51-53 for more gripping range (see pages 51-53 for more detail), suitable for blind bores
detail), suitable for through bores and operated with a part locator. and enables the sleeve to grip as much of the internal diameter as possible.
