The HSK spindle (Hohl-Schaft-Kegel, hollow shank taper) is a type of tool holder interface primarily used in high-speed cutting (HSC) and computer numerical control (CNC) machines. It is designed to provide a rigid and precise connection between the tool and the machine spindle, allowing for efficient power transmission and vibration reduction during high-speed milling, drilling, or turning operations.
The main features of the HSK spindle include:
Hollow cone profile: The HSK spindle features a hollow cone profile that provides a wider contact surface compared to traditional spindles with cross-sectional cones, ensuring better stability and torque transmission.
Clamping system: Tool clamping is achieved through a hydraulic or mechanical locking system, ensuring secure and reliable tool fixation during high-speed machining operations.
Vibration reduction: Thanks to its advanced design and wider contact surface, the HSK spindle helps reduce vibrations during high-speed milling operations, improving the quality of the machined surface and prolonging tool life.
Quick tool change: The HSK spindle allows for quick tool changes using a rapid locking system, reducing machine downtime and increasing overall productivity.
Adaptability: The HSK system is available in various sizes and cone types, allowing for greater flexibility and adaptability to the specific needs of different applications and machine tools.
Overall, the HSK spindle represents an advanced solution for high-speed milling applications, offering superior performance, increased stability, and greater overall efficiency in the machining process.
