Why choose to shrink Fit tool holders
   1. Fast loading and unloading of tools, heating by heat shrinking machine, with 13KW high power can complete the tool installation and clamping within 5 seconds, 
cooling only takes 30 seconds, unique water cooling device can prevent the accuracy of the tool holder from deteriorating.
   2. High precision and small run out. The tool mounting part does not have the parts such as the nut and collet required by the collet chuck.
It is simple and effective, the cold shrink clamping is strong and stable, the tool deflection is less than or equal to 3μ, 
the tool wear is reduced, and the high precision during high-speed processing is guaranteed.
    3. The crown is small and widely used. The ultra-thin tip part and abundant shape of the shank can be widely used for 
high-speed high-precision machining and deep hole machining.
   4, simple and efficient, long life. Hot loading and unloading operation, even if the same holder is hot-loaded more than 2000 times, 
the accuracy will not change, the stability is stable and reliable, and the service life is long.
