CNC EDM Small Hole Drilling Machine 703A is suitable for processing micro-holes, deep holes, nozzle holes, filter holes, pores and group holes of various metals and super hard conductor materials. It has special processing current circuit for processing aluminum.
Features:
703A Electrical Discharge Drilling Machine for Mini hole can drill wire-cut starting hole, filter hole, jet hole, gas hole, group holes and hole of super depth etc.
It can drill small holes on the various conductive materials, even semiconductor material, especially stainless steel, chilled steel, copper, aluminum and hard alloy etc.
This machine can drill on oblique and curved surface directly.
EDM blind hole fixed depth processing. Set the depth and start processing to get the desired blind hole.
The working water can be normal water or saponification fluid and no pollution is brought.
The operation is easy and convenient.
X, Y, Z axes have digital display devices.
Z axis DC servo drive and has the function of setting depth.
