HSK63F Shrink Fit Thermal Shrink Chuck for CNC Machines – Extreme Clamping Force and Precision

Index: H6FPDXTH10

The industrial thermal shrink chuck from the HSK63F Shrink Fit series is designed for stable and precise tool mounting in CNC machining centres. The thermal clamping system provides a clamping force of around 1300 Nm and high coaxiality. The absence of traditional clamping sleeves and nuts minimises vibrations during operation, which affects cutting precision, surface smoothness, and extends tool life. Tool replacement in the chuck requires the use of a dedicated induction heating device.

Design Advantages and Technical Properties:

• High Clamping Force (approx. 1300 Nm): The thermal connection guarantees secure holding of the tool shank without the risk of it being pulled out during operation under heavy loads.
• Design without Sleeves and Nuts: The monolithic structure reduces vibrations and eliminates mounting play and axial runout.
• Exceptional Coaxiality and Stability: Ensures smooth operation at high rotational speeds, protecting the cutting edges and spindle bearings from premature wear.
• Thermal Clamping (SHRINK-FIT): Enables repeatable tool seating using a dedicated heating station.

Intended Use and Scope:

The tool is intended for clamping mills and shank tools in the spindles of CNC machining centres that require the highest machining accuracy and operation at high cutting speeds.
