The hardinge Advantage

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 lever-

operated, 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.

Sure-Grip® 3-Jaw Power Chucks

Lever-Operated and Fully BalancedAll Sure-Grip Power Chucks are lever-operated, counter-centrifugal and dynam-

ically 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.

Direct MountSure-Grip Power Chucks mount

directly to all ANSI A2-4, A2-5, A2-6

and A2-8 spindles, eliminating the added

tolerance buildup when using special

adapter plates.

Large Thru-HoleSure-Grip Power Chucks have a large thru-hole

capacity to help reduce bar stock restrictions that

may be common to other power chucks. Refer to

the chuck specification charts on the following pages.

Optimum Gripping ForceUnlike 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

the right.

FEA Design AnalysisFinite 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.

Master JawsSure-Grip Power Chucks come standard with 1.5mm x 60° serrated master jaws designed to ISO specifications.

Other serrations are available on request.

Small Spindle to large Chuck large Spindle to Small Chuck

Spindle AdaptersSpindle 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).

Soft (Aluminum & Steel) Standard, Pie Jaws® and Standard Hard JawsOne set of soft machinable top jaws is included with each Sure-

Grip Chuck. Hard serrated single-step, soft standard-height point-

ed, 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.

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 work-pieces, there are advantages to using collets in other situations.
