CNC shrink fit holder SHRINK-FIT SLIM extended HSK63F d20 H150 RH-LH

Thermal shrink holder from the HSK63F Shrink Fit Slim series extended for CNC machines – high clamping force and machining reach

Index: H6FPDXTH20.A150M

Industrial, extended thermal shrink holder from the HSK63F Shrink Fit Slim series, designed for precise operations on CNC machining centres. The elongated and slim design allows for machining in hard-to-reach areas and deep recesses. The thermal clamping system provides a clamping force of approximately 1300 Nm and high coaxiality parameters. The absence of traditional clamping bushings and nuts minimises vibrations, which affects cutting accuracy, surface finish quality, and tool life. Changing the tool in the holder requires a dedicated device for induction heating.

Construction advantages and technical properties:

• Slim and elongated design (SLIM): Optimised geometry facilitates machining in deep cuts and hard-to-reach areas of the material.
• High clamping force (approx. 1300 Nm): The thermal connection guarantees secure holding of the tool shank without the risk of it being ejected under load.
• Bushing and nut-free design: 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 tool seating using a dedicated heating station.

Purpose and range of applications:

The tool is intended for clamping end mills and shank tools in spindles of CNC machining centres requiring increased reach in deep areas of the workpiece.
