Features: 

• Steel body material provides higher rigidity and wear resistance, enabling the chuck to withstand higher machining forces.
• Hardened and ground working surfaces prolong life while ensuring continuous accuracy and repeatability.
• Balanced scroll plate allows higher rotation speeds without excess vibration.
• Repeatability: 0,015 mm.
• Superior accuracy: small screws on the outside enable the chuck to be adjusted to position with nearly zero run-out (adjusting accuracy within 0,005 mm).
• The clamped workpiece is adjusted to the required concentricity by means of 4 (8 for sizes 400 mm, 500 mm, 630 mm) radially arranged adjusting screws.
• This precision chuck, with increased gripping accuracy, is made for universal use, but particularly advantageous for grinding machines, indexing heads and lathes
• Mounted on the machine tool spindle from the back of the chuck by using an adapter plate.
