不断屑阿，冷却压力提到30bar可以？越高约好
提高进给到0.4，降低线速度保证F不变，加工到120深停顿0.3S，这应该对节拍影响不打。

GUHRING对于深孔钻很有研究和实际成功经验。

Sandvik有10倍径以上的钻头吗？麻烦告诉一下型号。

要尊重科学，不要为了节拍而盲目提高切削参数。

看看是不是钻头刃口倒棱太大了，

建议选用可换刀片的钻头，刀片磨成群钻形式。

Since we do not know the detail of your drill we assume it is good for cutting A3 steel. We also had this problem before. Below is our solution: 1. drill a precise pilot hole, 2. increase your coolant pressure ( you can use high presssure coolant system), 3. selet a good drill for deep hole ( currently many tool makers have launched a similar type of drill like Mapal Mega Deep Drill (http://www.mapal.com/en/products ... ls/mega-deep-drill/), Walter Titex XD Bohrer drill and even OSG and Mitsubishi also developed this type of drill
