如果钻孔时孔的长度L与孔径d之比为五倍以上时,称为深孔加工。深孔加工通常有下列几种情况: 1.钻头细长,刚性及强度都很差,所加工的孔容易歪斜,钻头也容易折断; 2.切屑的排出困难,切屑通常挤在孔壁与刀杆之间,产生咬死现象,常常因此而扭断刀杆;

If the length of the hole when drilling hole diameter d and d ratio of more than five times, known as deep hole machining. Deep hole processing usually have the following situations: 1. Drill slender, rigid and strength are poor, the processing of the hole is easy to skew, the drill is also easy to break; 2. Chip discharge difficulties, the chip is usually crowded in the hole wall and the knife Between the rod, resulting in seizure, often resulting in broken arbor;
