DD703.30 Small Hole EDM Drilling Machine

The maximum depth ratio could be 300:1.
3 stage discharge voltage, can drill diameter from 0.2mm to 3.0mm.
XY hard rail, Z and W linear rail,Z with stepper motor.
With DRO for XY,can show the position of XYZ，with depth setting for Z axis.
Auto deep control for blind hole.
Accuracy (hole straightness) is less than 0.05 mm.
Can drill on oblique and curved surface directly.
Fast processing speed and low consumption.
Can use city water as coolant, low cost and no pollution.(Pure water is better)
