| 摘 要： | 群钻钻尖具有较好的排屑性能,但群钻钻尖参数源于高速工具钢材料,其几何参数不适合于硬质合金。本文设计出一种排屑性能良好的硬质合金群钻钻尖,试验证明其分屑、断屑能力及切削性能优于硬质合金标准钻尖钻头。

| Abstract: | The multi-facet drill point has the good performance in chip-evacuation but the drill tip parameters based on HSS are not fit for carbide drill.A new type multi-facet point suited for solid carbide drill is developed in this paper,and the experimental results show that the capabilities of this new drill point in chip-separation and chip-break are better than the conventional carbide drill point. |
