200mm Bison 6 Jaw Precision Scroll Chuck Type 3864
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
Chucks are supplied with one set of single piece hard inside jaws and one set of outside gripping jaws.
