Standard Type, F Type, R Type Chucks
To minimize machine downtime and provide operator safety, these Hydraulic Chucks use a simple hex wrench that requires only two to three turns for both clamping and unclamping. Tightening is complete when the clamping screw hits the bottom; controlling tightening torque is not needed. Once a Hydraulic Chuck is centered, the runout will not vary, even if a cutting tool is changed repeatedly. Runout of fewer than three microns at four times diameter can be achieved.
