摘　　要：利用试验手段对经过磁化后的高速钢钻头刀具耐用度进行了研究。研究结果表明:在钻削时,经过磁化处理的钻头比普通钻头的耐用度提高1.4倍。充磁后的剩磁强度越大,耐用度越高。通过实验研究,对磁化钻削中的一些现象进行了初步的探讨。The tool life of magnetized high speed steel drills was studied via means of experiments. The study result shows that during drilling, the magnetized drills were proved to have 1.4 times longer tool life than conventional ones, and the stronger the residu- al magnetism after magnetization, the longer the tool life has. At the same time some special phenomena in drilling with magnetized drills are discussed primarily.
