Workholding Design Expertise.
Hardinge is committed to being your single source for all of your workholding and
industrial products for your material-cutting needs. Well known for high accuracy
and precision, Hardinge manufactures collets, step chucks, toolholders, CNC tooling,
collet chucks, 3-jaw power chucks and chuck jaws.
Hardinge designed the Sure-Grip® 3-Jaw Power
Chuck using Finite Element Analysis (FEA) to assure
a quality product. Hardinge chucks are leveroperated, counter-centrifugal and dynamically
balanced to maintain jaw force. This chuck design
is superior to a non-counterbalanced, wedge-style
chuck that could be slowing down your removal
rates. Read about the Sure-Grip benefits over the
next few pages. Hardinge 3-Jaw Power Chucks and
Quick-Change Chucks are adaptable to all brands
of CNC lathes and are competitively priced.

Unlike conventional chucks
that are not counterbalanced,
the Sure-Grip Jaw Chuck with
its counterbalance feature
helps maintain optimum
gripping force at high RPM
as shown on these calculated
gripping charts shown at

Lever-Operated and Fully Balanced
All Sure-Grip Power Chucks are lever-operated, counter-centrifugal and dynamically balanced. This enables you to continually operate your CNC lathe at higher
spindle speeds and feed rates with less concern for loss of jaw force normally
associated with other manufacturer’s chucks.

Sure-Grip® 3-Jaw Power Chucks
FEA Design Analysis
Finite Element Analysis (FEA) techniques are used to design and build
Sure-Grip chucks to ensure optimum rigidity and fatigue life. Unique design
software accurately depicts the structural deflections, stress levels, thermal
response and vibration response of the assembled components.
Extreme case loadings are modeled in FEA to determine the effects. This
technique fine tunes the engineered design and aids in defining operating
specifications while verifying the chuck life expectancy.
Spindle Adapters
Spindle Adapters are required when mounting a large chuck to a small spindle (i.e: A2-8 chuck
to an A2-6 spindle), or when mounting a small chuck to a large spindle (i.e.: A2-8 chuck to an
A2-11 spindle).

Sure-Grip Power Chucks come standard with 1.5mm x 60° serrated master jaws designed to ISO specifications.
Other serrations are available on request.
Soft (Aluminum & Steel) Standard, Pie Jaws®
and Standard Hard Jaws
One set of soft machinable top jaws is included with each SureGrip Chuck. Hard serrated single-step, soft standard-height pointed, soft medium-height pointed and flat, and soft standard-height
flat jaws with 1.5mm x 60° serrations are available. Hardinge also
provides replacement jaws for other brands of chucks.

Quick-Change Sure-Grip® Chucks
Available for All
Brands of CNC
Lathes!
Increase efficiency and profitability
while maintaining accuracy!
•Revolutionary Quick-Change
top jaw design (patented)
•Each top jaw changes with the
simple turn of a single locking
bolt in less than one minute
(much faster than conventional jaws)
•Lever-operated for high grip force
•Hardinge-designed safety
feature utilizes centrifugal force
and a unique locking system,
eliminating the possibility of the
quick-change jaws coming off
during operation
•Larger machineable jaw area
allows a greater variety of
workpieces to be held than with conventional chucks
•Counter-centrifugal design
provides for least grip force loss
•No special tools required
•6", 8", 10" and 12" direct-mount
chucks
•Master jaw serrations
1.5mm x 60°
•Will accept standard jaws

Collet Chucks
for precision collet work
on a chuck-style lathe
Hardinge HCAC™ Collet Adaptation Chucks
convert a chuck-style spindle into a collet-style
spindle to accommodate higher precision work.
You may be able to finish a part in one setup,
thus eliminating a secondary operation and
reducing turnaround time. Collet Adaptation
Chucks can increase both your productivity and
job flexibility. While chucks are perfect for large,
non-symmetrical or variable-diameter workpieces, there are advantages to using collets in
other situations.
Collets offer longer life and improved accuracy…
•A hardened and ground collet has a much longer life and maintains a more critical part
tolerance than machined chuck jaws do, making
it more appropriate for long run jobs. Jaws have to be re-bored over long runs, creating
substantial downtime.

•Hardinge Collet Adaptation Chucks provide a
precision bearing surface for better accuracy
than can be achieved with jaw chucks.
•Collets are available in special accuracy for super precision work that you would not be able to perform with a chuck.
•The use of Collet Chucks offer less chance for
expensive wrecks. Have you ever had to replace
a turret assembly or a spindle or had to have
your jaw chuck rebuilt? Those costly repairs can
often be a result of top jaw interference.
•Hardinge Collet Chucks improve accuracy and
productivity where and when you need it!
