1.Main Function

A.There is a window on the machine bed for pump pressure, which is easy and convenient to look and adapt water pressure.

B.Servo control system is adopted and improved, which make drilling re-track speed 2 times quicker than dB703

C.There is slider water tank, which saves space and is more environmental.

D.There is oil-tank for lubrication, which is more convenient to operate and fluid to lubricate.

E.Able to drill various conductive metals, such as stainless steel, chilly steel, solid carbide, copper, aluminum etc.

F.Able to drill holes range from diameter 0.2- 3mm with max depth-diameter ration 300:1.

G.It is more stable while drilling hole of 0.2mm

H.Drilling speed 30-60mm/min

I.Able to drill directly into bevel or curve surface.

J.Three axis digital display

K.Drilling depth positioning function for Z axis

L.Control system can drill group hole and positioning automatically.
