目前,“钻攻”已成为螺纹加工领域中一项最热门的新工艺。这种方法是将浅孔钻削及螺纹铣削合二为一——应用单轴扦及一把组合刀具直接高速加工螺纹孔。加工时,一把尖端有钻削刃而刀体带有螺纹铣削刃的组合刀具连续不停的高速旋转,刀具先在工件上钻削出规定深度的孔并退出一个螺距的距 At present, “drilling attack” has become one of the most popular new process in the field of thread processing. This method is a combination of shallow hole drilling and thread milling - the use of single-axis skew and a combination of direct high-speed processing of threaded holes. Processing, a cutting edge of the cutting edge of the cutter body with a combination of thread milling cutter continuous high-speed rotation, the first tool to drill the hole depth and exit a pitch pitch
