XD® -Technology - Drilling Strategy钻头使用技术
for diameters below 10 mm and flute lengths longer than 16 x D 对于直径小于10毫米以及排削槽长径比小于 倍径的XD钻头 毫米以及排削槽长径比小于16倍径的 对于直径小于 毫米以及排削槽长径比小于 倍径的 钻头
TITEX recommends the following drilling strategy to improve tool life and reliability: TITEX 推荐按照如下操作来使用以提高刀具寿命和加工过程稳定性
1. Spot drill or drill pilot hole with ALPHA 4 Plus Micro or ALPHA 2 Plus Micro 用ALPHA 4 Plus Micro or ALPHA 2 Plus Micro 引导钻来钻引导孔

Application Areas 应用领域
– Steel- and cast iron materials – 钢件-铸铁 – Stainless steel 不锈钢 – Non-ferrous metals, such as – 非铁金属 – Aluminum alloys 铝合金 – Copper alloys 铜合金 – Magnesium alloys 镁合金 – Titanium alloys 钛合金
• Coolant Pressure 冷却压力
(10-20 bar/145-290 PSI are sufficient, higher pressures are possible) 10-20BAR 是可以了，再高一点也可以
• Coolant Pumps 冷却泵
(danger of overheating due to back-water, 冷却液循环可能造成过热 flow control units can cause pump to switch-off)
- Retract drill from the hole

Need-to-Know about Micro Drills with Internal Coolant 需要知道的一些关于带内冷微钻的知识
• Filter-Mesh 过滤网孔
(min. 0,5 x Diameter of coolant hole 最小是内冷孔直径的一半)

Activities/improvements since launch in i-pac 2/2007 改进措施
• improvement of blanks (run-out <0,02mm) 跳动小于2丝 • flute polishing 排削槽抛光处理，减小排削阻力 • edge treaTment with small tolerances 刃口小的公差处理 • checking of coolant holes after edge treatment 刃口处理后再复查内冷孔
4. Increase cutting speed and feed to values recommended by TEC for A6588TML 增加切削参数到样本推荐值 并且不需要退出。
Continue drilling without any peck !
5. Reduce speed to max. 500 rpm or stop the spindle upon reaching final depth 结束时将转速降低到500转/分或者停下来退出。

3. Reduce cutting speed and feed to 25 - 30 % of values recommended for A6588TML 开始钻时将线速度和进给降低到样本推荐值的25%到30%，钻到3倍径。
- Start drilling with reduced cutting speed and feed down to 3 x d depth.
