In this study. an ultra high speed micro drilling system was made by using a precision X-Y servo driving table.The glass epoxy print circuit board(PCB) was drilled by the above system under various drilling conditions. The drilling performances of HSS drills with 40-100 mum in diameter were tested under dry and wet conditions. As the results, it was shown that the drill feed rate 2 IOTAm /rev with higher drill speed under wet condition was suitable for micro drilling of PCB.Stepping feed also gave good results. The effect of oil supply on micro drilling operations was very significant. Especially, the oil supply was very effective to reduce the torque which is the main cause of micro drill damage and lower tool life. The sintered carbide drill resulted in longer tool life and higher quality of drilled hole surfaces and In reducing the bar due to lower tool wear. Oil mist application was also very effective to improve the micro drilling performance. As the result of this study, it was made clear that the ultra high speed micro drilling with sintered carbide tool was effective to drill out many micro hole S on PCB under oil mist conditions.

本研究利用精密X-Y伺服驱动工作台研制了超高速微细钻孔系统，并在不同的钻孔条件下对玻璃环氧印刷电路板（PCB）进行了钻孔实验。对直径为40-100 μ m的高速钢钻头在干、湿条件下的钻削性能进行了测试。结果表明，在潮湿条件下，钻头进给速度为210 TAm/rev，钻头转速较高，适合于PCB微细孔加工，步进进给也能获得较好的加工效果。石油供应对微型钻井作业的影响非常显着。特别是，供油是非常有效的，以减少扭矩，这是微钻损坏和降低刀具寿命的主要原因。烧结硬质合金钻头导致更长的刀具寿命和更高的钻孔表面质量，并由于更低的刀具磨损而减少了棒。油雾的应用对于提高微钻性能也非常有效。研究结果表明，在油雾条件下，用硬质合金刀具进行超高速微细钻削可以有效地在PCB上钻出多个微孔S。
