LPD-YAG-III Laser Precision Driller for the Wire Drawing Dies

   LPD-YAG-III Laser Precision Driller for the Wire Drawing Dies is a new developing laser driller, it can drill the smallest hole 10 micrometers in diameter on the natural diamond,it can also drill bigger hole(several millimeters in diamter)on the natural diamond,polycrystalline diamond compact(PDC), the hole is bright and the shape is trumpet.Many wire drawing die makers in China have used this laser driller,and several Taiwan,Korean,Indian and Japanese wire drawing die makers have also used it.
