630mm Bison 3 Jaw Adjustable Scroll Chuck Steel Body

630mm Bison 3 Jaw Adjustable Scroll Chuck Steel Body 3564

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: 0.015mm

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 front of the chuck by using an adapter plate. The inside and outside hard jaws are supplied as standard.
