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

Swing Clamp Chucks

Swing Clamp Chuck Example

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

    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

    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"
    •
