CK160S-3 Central Hollow 3 Jaw Chuck for Lathe Machine - 42.3KN Clamping Force, 2-170mm Range
The CK160S-3 Central Hollow 3 Jaw Chuck is engineered for precision lathe machine operations. This pneumatic chuck features a central hollow design that enables processing of bar materials and preform workpieces with exceptional accuracy.
The three-jaw mechanism utilizes a chuck wrench to rotate any of the three umbrella teeth, driving the plane thread to rotate and moving all three jaws simultaneously for self-centering and secure workpiece clamping. While all three bevel gears serve the same function, careful inspection reveals variations in clamping accuracy between them.
