EMD Drilling Machine DD703, DK703
small holes high speed drilling
High speed small hole drilling machine adopt electrode to drill hole according electrical discharge theory, put on high frequency Pulse electrical power between electrode and workpiece to create small pulse, cooperate with high pressure water plush to make more higher speed erosion, especially fit to drill hole diameter as 0.2mm-3.0mm on stainless, hardened steel, cooper, aluminum, and hard alloy steel, the depth-diameter ration can reach to 300:1. Be able to drill directly into bevel or curve surface. This machine is widely used to drill hole which used to be thread wire, and chemical fiber spinneret, spinneret hole of spinneret plate, filter plate, group holes of sieve plate, engine blade, heat dissipation hole of cylinder, the hydraulic, oil way of air operated valve, stomata. The machine can also erode the drill bit or taps broken in the working piece without destroy the original hole or screw.
- Can dill deep hole with diameters 0.3mm-3mm (the depth-diameter ratio is 300:1)
- Can dill wire-cut starting hole, filter hole, jet hole, gas hole, group holes and hole of super depth etc
- Can drill on oblique and curved surface directly.
- Can easily erode the drill and screw tap ect which is broken in the workplace and not destroy the screw thread of the holes.
- The speed of drilling hole is 30mm-60mm depth per minute(it is different for different material)
- Can drill small holes on the various conductive materials, especially stainless steel, hardened steel, copper, aluminium and hard alloy etc.
- Z axis with fixing function.
