Swing Clamp Chucks · O.D. Collet Chucks · Centralizing & Compensating Chucks · Competetive Advantages & Strengths

Swing Clamp Chucks

Swing Clamp Chuck Example		Swing Clamp Chuck larger image

Swing Clamp Chuck Advantages		Holds irregular shaped pieces that ordinary chucks cannot accommodate High ratio of clamping power ensures proper part pull down against part stop Virtually no internal wear maximizes your investment Sealed design along with proper greasing provides solution to costly downtime

TIR		Guaranteed within your balance specs or better Repeatability of less than .0002

Swing Clamp Chuck Features		O.D./I.D.: Ensures flexibility to engineers and tool designers Collet: Designed into the body ensuring part centralization before swing clamps chuck part Clamping: Allows for chucking of the most irregular parts needed to be machined, balanced, or inspected Compensating Chuck jaws float to grip the work-piece in pre-established position Allows for clamping on castings that have variable thicknesses Allows for chuck to be balanced out on machine Integrated air cylinder

O.D. Collet Chucks

O.D. Collet Chuck Example		Slip Yoke Chuck larger image

O.D. Collet Chuck Features		Internal locator, locates part central prior to clamping Gripping force centralized over entire O.D. of part ensuring no part distortion Greatest form of concentricity and repeatability outside of diaphragm chucks Higher degree of simplicity than standard (3) jaw chucks Simple part change over No centrifugal force lost, able to run at >6,000 rpm’s

TIR		Guaranteed within your balance specs or better Repeatability of less than .0001"

Centralizing & Compensating Chucks

Centralizing & Compensating Chuck Example		Trunnion Chuck larger image

Centralizing & Compensating Chuck Features		Allows for extreme accuracy and repeatability for balance application Replaceable wear items along with routine maintenance allows for long tool life Sealed design keeps contaminates out in order to maximize your investment

Centralizing		Jaws centralize the part before clamping equidistant from centerline

Compensating		Chuck jaws float to grip the work-piece in pre-established position

TIR		Guaranteed within your balance specs or better Repeatability of less than .0002"
