摘要
整体硬质合金钻头在加工塑性材料时断屑、排屑比较困难。分析实际加工条件和被加工材料的特征后,替换了原来使用的进口"皇冠"钻头。本文介绍替换的试验过程、结果,经试验验证超过了客户期望的寿命。
Problem of breaking chip and the chip draining in the machining process when deep-hole drilling on carbu- rized Q345. The characteristics of the material drilling are inwistigated and novel dill is replacment the crown drill Ex- periments and Iest - run reveal thai the tool-life of the drill increases by many times in comparison with that of the eonven- lional ones.
