31GENERAL DRILLING HANDBOOKHydraulic Chuck12543Hydraulic Expansion Technology1 The Oil Chamber System Then the oil chamber system filled with hydraulic fluid, it has a damping effect on the clamped tool.2 The Expansion Sleeve The expansion sleeve expands against the tool shank. This clamping process first centers the tool shank before fully clamping it over the whole surface.3 The Base Body The machine side interface is located on the base body.4 The length adjustment screwfor fast and easy presetting.5 The dirt groove The enormous clamping pressure of the HYDRO-FIT SF chuck creates a displacement of oil, grease, or lubricant residues into the groove, causing surfaces to remain dry.In the hydraulic chuck, the tool is clamped by fluid pressure. To clamp / unclamp the chuck, simply turn the clamping screw. When tightening the clamping screw, the force is transferred to the piston, which in turn generates hydraulic fluid pressure. The hydraulic fluid pressure is transmitted to the wall-mounted sliding sleeve. This pressure causes the sleeve to compress around the tool shank creating a concentrated clamping force. vibration dampingThe advantages of the hydraulic chuck include high accuracy, user simplicity, and quick tool changes. Using this type of chuck can reduce vibration and significantly extend tool life.
