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

Index: H6FPDXTH06

The industrial thermoshrink holder of the HSK63F Shrink Fit series is designed for stable and precise tool clamping in CNC machining centres. The thermal clamping system provides a clamping force of around 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. Changing the tool in the holder 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 slipping during operation under heavy load.
• No collets and nuts construction: Monolithic design reduces vibrations and eliminates mounting play and axial runout.
• Exceptional concentricity and stability: Ensures smooth operation at high rotational speeds, protecting tool edges and spindle bearings from premature wear.
• Thermal clamping (SHRINK-FIT): Enables repeatable seating of tools using a dedicated heating station.

Purpose and Application Range:

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