What are the categories of heat shrink chucks?
Heat shrink chucks can be divided into 3 categories according to wall thickness, tool holding length and interference.
1. Standard type: produced in Germany.
2. Reinforced type: thicker wall, used for heavy-duty milling tool clamping in the aerospace industry.
3. Lightweight: longer thin wall, used for deep mold cavity processing.
What are the advantages and disadvantages of heat shrink tool holders?
1. Quick loading and unloading of tools. Using heat shrink machine heating, the high power of 13KW can complete the installation and clamping of tools within 5 seconds, and cooling only takes 30 seconds. The unique water cooling device can prevent the deterioration of tool holder accuracy.
2. High precision and small runout. The tool installation part does not have the nut and collet required by the collet chuck. It is simple and effective. The cold shrink clamping is strong and stable. The tool runout is ≤3μ, which reduces tool wear and ensures high precision during high-speed processing.
3. The handle is small and widely used. The ultra-thin tip part and the rich shape changes of the tool holder can be widely used in high-speed and high-precision processing and deep hole processing.
4. Simple and efficient, long life. Hot loading and unloading operation, the same tool holder will not change its accuracy even if it is hot loaded and unloaded more than 2,000 times. The stability is stable and reliable, and the service life is long.
5. You need to buy a heat shrink machine, which costs from thousands to tens of thousands.
6. After using it for thousands of times, when the oxide layer peels off, the accuracy is not that high.
