鉆削加工是孔加工的一種基本方法，鉆孔經(jīng)常是在鉆床，車床，銑床等設(shè)備上完成的。在各類機器零件上經(jīng)常需要鉆孔，因此鉆削的應(yīng)用還是很廣泛。因為現(xiàn)在鉆頭的制作工藝的提升，鉆削已經(jīng)不局限于粗加工了，好的鉆頭和加工設(shè)備也可以加工較高精度和粗糙度要求高的孔。

麻花鉆鉆尖示意圖
鉆削力在各切削刃的大約分配比例， 如下表所示。可見在鉆一般材料時，軸向力主要來自橫刃，而扭矩主要由主刃 產(chǎn)生。但需要注意的是，當(dāng)鉆削某些彈 性模量E較小的材料(如鈦合金)時，由于 彈性恢復(fù)大，使得孔壁與鉆頭刃帶的摩擦力矩增加，可約占總力矩的64%。
