臥加還是立加啊？

不斷屑阿，冷卻壓力提到30bar可以？越高約好
提高進給到0.4，降低線速度保證F不變，加工到120深停頓0.3S，這應該對節拍影響不打。
若還不行，觀察鉆頭槽型是否利于斷屑
GUHRING對于深孔鉆很有研究和實際成功經驗。

Sandvik有10倍徑以上的鉆頭嗎？麻煩告訴一下型號。

要尊重科學，不要為了節拍而盲目提高切削參數。

看看是不是鉆頭刃口倒棱太大了，

建議選用可換刀片的鉆頭，刀片磨成群鉆形式。

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
