SJD703 ELECTRICAL DISCHARGE MACHINING FOR MINIHOLE

SJD703 High Speed Small Hole EDM--- high efficiency, convenient Working table travel is 300mm×400mm Z axis travel is 270mm+300mm Processing thickness is 0~300.

Can drill deep hole with diameters 0.3mm ~ 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, aluminium 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
