抛物线槽形钻头的耐用度及刃磨方法的试验研究

针对抛物线槽形钻头的耐用度及刃磨方法进行了较深入的研究。结果表明，对于不同的加工对象，钻头应采用不同的刃磨方法，才能发挥其钻深能力强、耐用度高的优良特性。

Comprehensive studies of the durability of the parabolic flute drill and the method of gringing its cutting edge are carried out with the result that different grinding methods should be used for different objects to be machined for the full utilization of the superiorities of the high capability and high durability of the drill,and for the determination of the method of grinding the cutting edge.
