HSK63F Shrink Fit Thermo Shrink Holder for CNC Machines – Extreme Clamping Force and Precision

Index: H6FPDXTH08

Industrial thermo shrink holder from the HSK63F Shrink Fit series, designed for stable and precise clamping of tools in CNC machining centres. The thermal clamping system provides a clamping force of about 1300 Nm and high concentricity. The absence of traditional collets and nuts minimises vibrations during operation, which affects cutting precision, surface smoothness, and extends the tool life. Replacing the tool in the holder 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 slipping out during operation under heavy load.
• Design without collets and nuts: The monolithic construction reduces vibrations and eliminates mounting play and axial runout.
• Exceptional concentricity and stability: Ensures smooth operation at high rotational speeds, protecting the tool edges and spindle bearings from premature wear.
• Thermal clamping (SHRINK-FIT): Allows for repeatable tool seating using a dedicated heating station.

Intended Use and Scope:

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