The Hydraulic Chuck is a high-precision tool holder widely recognized for its superior clamping accuracy, stability, and vibration-damping properties. Its primary function is to secure cutting tools with high concentricity, ensuring minimal runout and maintaining exceptional surface finish in machining. Hydraulic chucks use a built-in hydraulic mechanism to generate uniform clamping force around the tool shank, which reduces stress points compared to traditional clamping methods. They are used in milling, drilling, reaming, and finishing applications where precision and repeatability are essential. By eliminating micro-vibrations and ensuring stable clamping, hydraulic chucks enable manufacturers to achieve better dimensional accuracy, extended tool life, and higher productivity across both low-volume precision parts and large-scale production runs.
Ultra-High Accuracy: Runout accuracy typically ≤0.003 mm, delivering superior machining precision.
Excellent Vibration Damping: The hydraulic mechanism absorbs cutting vibrations, improving surface quality and protecting both the tool and spindle.
Uniform Clamping Force: Provides 360° tool shank support, reducing stress concentrations and ensuring stable performance at high speeds.
Easy Tool Changes: With a simple hex key adjustment, operators can quickly clamp or release tools without the need for additional equipment.
Wide Compatibility: Available in HSK, BT, CAT, PSC, and other interface standards, making them adaptable to different CNC machine types.
Versatile Application: Suitable for high-speed finishing, reaming, drilling, and light milling where accuracy is critical.
These features make hydraulic chucks an ideal choice for manufacturers seeking a balance of precision, efficiency, and tool longevity.
Clamping Range: Typically 3 mm – 32 mm depending on the model.
Runout Tolerance: ≤0.003 mm, supporting high-precision finishing operations.
Shank Interface: Available in HSK (A, E, F types), BT, CAT, PSC, and other international standards.
Length Options: Standard, medium, and extended lengths for different machining depths.
Balancing Grade: G2.5 at 25,000 RPM, ensuring excellent performance in high-speed spindles.
Clamping Method: Hydraulic chamber activated by a simple hex key for reliable and repeatable clamping.
With these specifications, hydraulic chucks can be applied in both high-speed finishing and precise drilling operations, delivering consistent results across different machining conditions.
Preparation: Clean both the tool shank and chuck bore before installation to prevent dirt or chips from affecting clamping accuracy.
Clamping: Insert the cutting tool to the required depth and tighten using the supplied hex key until resistance is felt, ensuring secure hydraulic pressure.
Operation: Match cutting parameters with the clamping range and spindle speed. Avoid exceeding maximum RPM specifications.
Tool Changes: Replace tools quickly by releasing hydraulic pressure with the hex key — no complex adjustments needed.
Maintenance: Regularly inspect the hydraulic mechanism and seals. Store chucks in a clean and dry environment to prevent hydraulic fluid leakage or internal corrosion.
By following these instructions, hydraulic chucks guarantee stable tool holding, long-term precision, and reduced downtime in machining operations.
