CNC shrink fit holder SHRINK-FIT HSK63F d16 H76 RH-LH

HSK63F Shrink Fit heat shrink holder for CNC machines – extreme clamping force and precision

Index: H6FPDXTH16

Industrial heat shrink holder of 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 around 1300 Nm and high coaxiality. The absence of traditional collets and nuts minimises vibrations during operation, which affects cutting precision, surface smoothness, and extends the tool life. Tool change 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 ensures secure holding of the tool shank without the risk of it slipping out during operation under high load.
• Collet and nut-free construction: The monolithic design reduces vibrations and eliminates mounting play and axial runout.
• Exceptional coaxiality 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 range of application:

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