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

Index: H6FPDXTH25

Industrial thermal chuck from the HSK63F Shrink Fit series, designed for stable and precise tool gripping 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 impacts cutting precision, surface smoothness, and extends the lifespan of cutting edges. Changing the tool in the chuck requires the use of a dedicated induction heating device.

Structural 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 pulling out during heavy load operations.
• Sleeve and nut-free design: The monolithic construction reduces vibrations and eliminates mounting play and axial runout.
• Exceptional coaxiality and stability: Ensures smooth operation at high rotational speeds, protecting tool edges and spindle bearings from premature wear.
• Thermal clamping (SHRINK-FIT): Allows for repeatable seating of tools using a dedicated heating station.

Intended Use and Scope of Application:

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