なぜhss工具の焼きばめができるのか？＜　焼きばめ装置 power clamp　＞ | オーエスジー

High-speed tools and shrink fit holders are similar in material and have similar coefficients of thermal expansion. Therefore, in the past, when the tool was burned out, it swelled along with the holder and pull out disappeared. However, the Power Clamp has a short heating time, which allows it to be burned off before the heat is transferred to the tool itself.
