Main Application

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, hardenedsteel, cooper, aluminum, and hardalloysteel, 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.

Application 

  Mainly used for processing unmanageable deep pinhole such as threading hole,   
drilling hole on ultra-hard conducting material for  wire cutting on, nozzle opening of oil pump,
spinneret orifice of spinning die, oil way of hydropneumatic components and cooling hole of engine
