Technical Information Hydraulic Chucks General Design Function Effect Tightening the piston clamping screw exerts force on the pressure piston, which The hydraulic clamping system has a dampening effect. Vibration in a mechanical presses the hydraulic fluid, exerting force on the thin-walled expansion sleeve. This clamping system can cause microcracking on insert cutting edges. This is pressure causes the sleeve to compress around the tool shank, creating a highly prevented by the hydraulic expansion chuck and results in higher production concentric clamping force. quality and up to 4x better tool life.
