The HSK toolholder has become the gold standard for high-speed/ultra-high-speed machining through its innovative design of hollow short taper + double-sided positioning, and is especially suitable for high-precision scenarios such as five-axis machining centers and milling machines. In the future, it is necessary to break through the bottleneck of manufacturing processes, optimize the reliability standards under dynamic working conditions, and expand its application in difficult-to-process materials in aerospace.
