Product Description

 Small Hole EDM KD703A

The machine characteristics:
* Can drill deep hole with diameters 0.2mm ~ 3mm (the depth-diameter ratio is 300: 1)
* The speed of drilling hole is 30mm~60mm depth per minute (it is different for different material)
* Can drill wire-cut starting hole, filter hole, jet hole, gas hole, group holes and hole of super depth etc.
* Can drill small holes on the various conductive materials, even semiconductor material, especially stainless steel, chilled steel, copper, aluminum and hard alloy etc
* Can drill on oblique and curved surface directly
* Can easily erode the drill and screw tap etc which is broken in the workpiece and not destroy the screw thread of the holes
* 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 has the function of setting depth
