• Mount: Plain Back
• Through-Hole Diameter (Decimal Inch): 2.1653
• Body Material: Steel
• Reversible Jaws: Yes
Features:
• 3 jaw, self-centering scroll chuck
• Steel body extends machine life while providing higher rigidity and greater wear resistance
• Hardened and ground working surfaces ensure longer life with maintained accuracy and repeatability
• Balanced scroll plate and chuck allows higher rotation speeds without excess vibration
• Repeatability: 0.0006"
• Superior accuracy: small screws on the outside enable the chuck to be adjusted to position with nearly zero runout (adjusting accuracy within 0.0002")
• The clamped workpiece is adjusted to the required concentricity by means of 4 radially arranged adjusting screws
Application:
• This precision chuck, with increased gripping accurcy, is made for universal use, but particularly advantageous for grinding machines, indexing heads and lathes.
• Especially suitable for machining parts with top concentricity
• Gripping force is equally distributed over 6 jaws, allowing the chuck to machine thin-walled workpieces and clamp without deformation
