If you're aiming for the ultimate in precision, repeatability, and surface finish in your machining operations, hydraulic expansion chucks are an excellent choice. Designed for exceptional clamping accuracy and vibration dampening, these holders are a must-have for high-performance CNC applications.
Hydraulic expansion chucks (also known as hydraulic tool holders) use fluid pressure to create a secure and concentric clamping force around the tool shank. By eliminating mechanical clamping methods like collets or set screws, they deliver superior runout accuracy - typically less than 3 microns.
These chucks are ideal for finishing operations, reaming, drilling, and milling where accuracy and surface quality are paramount.
Ultra-High Precision - Achieve consistent concentricity with minimal runout
Vibration Damping -Â Improved tool life and surface finish thanks to reduced chatter
Quick Tool Changes - Simple tightening with an Allen key - no heating or torque wrenches required
Coolant Through Options - Many chucks support internal coolant for enhanced chip evacuation
Extended Tool Life - Even clamping pressure protects cutting tool integrity
Consider the following when selecting your hydraulic chuck:
Spindle Interface
Match the chuck to your CNC machine’s spindle type (e.g., HSK63, BT40, ISO40).
Tool Shank Size
Ensure the chuck bore size fits your cutting tool (commonly Ø6mm to Ø20mm). Use reduction sleeves if needed.
Application
For high-precision milling or drilling, choose a compact or slimline chuck.
For deep cavity work, look for extended reach chucks.
High Balance
For high-speed machining balanced up to 25,000rpm. G2.5 hydraulic chucks aid with minimising vibration and maintain accuracy at high speeds.
Coolant Supply
Select chucks with internal coolant channels if your application benefits from through-tool cooling.
