Hydraulic chucks are among the most advanced tool holding systems for CNC machining centres, designed for operations that demand high spindle speeds, maximum runout accuracy and superior surface finish.

Key Features and Technical Advantages
- Outstanding Runout Accuracy: Delivers an exceptionally tight runout tolerance of 0.003 mm (3 µm), measured at 4×D from the tool tip [00:59].
- Hydraulic Clamping with Minimal Effort: Internal oil chambers and a single actuating screw generate maximum clamping torque with just one hex key and minimal operator effort [02:43], [03:25].
- Superior Vibration Damping: The hydraulic fluid inside the body absorbs micro-vibrations generated during cutting, significantly extending tool life and producing a smoother surface finish on the workpiece [01:26].
- Precision Reduction Sleeves: Used with dedicated precision-ground reduction sleeves. The sleeves are fully integrated at the rear and front, transmitting hydraulic pressure directly to the cutting tool shank [00:24].
- Corrosion Resistance and Stable Operation: Special surface coating and precision grinding make the chuck resistant to rust and corrosion, and ensure stable operation at high RPM without additional balancing [00:41].
Applications and Maintenance Requirements
- Applications: Preferred for high-precision work that pushes machine performance to its limits in the aerospace, defence, medical, precision mould & die and automotive industries [01:54].
- Periodic Maintenance: To prevent the hydraulic oil from losing viscosity and performance over time, hydraulic servicing should be carried out by an authorised service centre after specified operating intervals [01:08].
