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

Index: H6FPDXTH20

Industrial thermal chuck from the HSK63F Shrink Fit series, designed for stable and precise tool holding in CNC machining centres. The thermal clamping system provides a clamping force of approximately 1300 Nm and high coaxiality. The absence of traditional clamping sleeves and nuts minimizes vibrations during operation, which affects cutting precision, surface smoothness, and extends blade life. Tool change in the chuck requires a dedicated induction heating device.

Structural Advantages and Technical Properties:

• High clamping force (approx. 1300 Nm): The thermal connection guarantees secure retention of the tool shank without the risk of it loosening during operation under heavy load.
• No sleeve and nut construction: Monolithic design reduces vibrations and eliminates mounting play and axial runout.
• Exceptional coaxiality and stability: Ensures smooth operation at high rotational speeds, protecting tool blades and spindle bearings from premature wear.
• Thermal clamping (SHRINK-FIT): Allows for repeatable tool seating using a dedicated heating station.

Application and Scope of Use:

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