| 摘 要： | 在分析目前八种钻尖基本形式的基础上,针对普通麻花钻加工精度低耐用度低和原锥面四刃钻头半精加工效率低,主刃负荷分布不合理等缺点,首次提出理论刃形曲线和摆线刃刃磨法,将之用于四刃钻头设计取得了良好的效果。

| Abstract: | Based on the analysis of the present drill point grinding methods, in order to improve the drilling accuracy and durability of the twist drill and overcome the defects of low efficiency of semifinishing and irrational cutting load distribution along the cutting edge of the four-fluted drill, the authors have devised a theoretical cutting edge curve and cycloidal grinding method(CGM) for the first time, by means of which much better results have been achieved. |
