What are the advantages and disadvantages of Shrink fit chucks

Shrink fit chucks adopts the technical principle of thermal expansion and cold contraction, and uses the induction technology of the tool handle heat shrinking machine to heat. Heat shrinkable tool handle is also called: sintered tool handle, thermal expansion tool handle, etc. It can realize omnidirectional ultra-high precision machining. The 360 ° complete clamping accuracy and rigidity of the tool are greatly improved.

Advantages of heat shrinkable TOOL HOLDER:
1. Quickly load and unload the tool, use the heat shrinking machine for heating, the 13KW high power can complete the tool installation and clamping in 5 seconds, and the cooling only takes 30 seconds. The unique water cooling device can prevent the accuracy of the tool handle from deteriorating.
2. High precision and small runout. The tool installation part does not have the nut and collet required by the collet collet, which is simple and effective. The cold shrink clamping strength is stable, and the tool deflection is ≤ 3 μ, The tool wear is reduced and the high precision of high-speed machining is ensured.
3. The handle head is small and widely used. The ultra-thin tip part and rich tool handle shape changes can be widely used in high-speed and high-precision machining and deep hole machining.
4. Simple and efficient, long service life. For hot loading and unloading operation, even if the same tool handle is hot loaded and unloaded for more than 2000 times, the accuracy will not change, the stability is stable and reliable, and the service life is long.

Disadvantages of heat shrinkable Tool Holder:
1. You need to buy heat shrinkers, which are available in thousands to tens of thousands.
2. When the oxide layer is peeled off after thousands of times of use, the accuracy is not so high.
