Air Membrane Hole Precision Perforation CNC Electric Discharge Machining Tool

In order to meet market demand, improve the performance of aero engines, and achieve the cooling effect of turbine blade film, a CNC EDM machine for precision film-cooling holes has been developed.
1. Using the same electrode for EDM of film-cooling holes with deep-hole and dimpling structures.
2. The film-cooling hole spindle mechanism meets functions such as high-precision electrode rotation and automatic feeding, internal hollow high-pressure flushing, external electrode high-pressure flushing, electrode power supply and insulation, internal and external high-pressure fluid sealing, and corrosion resistance.
3. An online controllable high-frequency pulse discharge power supply that, based on pulse width and energy control, achieves remelting layer thinning and thickness regulation.
