In order to adapt to market demand, improve the performance of aircraft engines, and meet the cooling effect of turbine blade film cooling, a precision hole CNC electrical discharge machining machine for film holes has been developed.
1. Use the same electrode for electrical discharge machining of film holes with deep hole and baffle hole structures.
2. The spindle mechanism for film holes meets functions such as high-precision rotation and automatic feeding of the electrode, high-pressure flushing from the inside, high-pressure flushing from the outer ring electrode, electrode power supply and insulation, sealing of high-pressure flushing inside and outside, and corrosion resistance.
3. An online controllable high-frequency pulse discharge power supply, based on the pulse width and energy control of the power supply, achieves thinning and thickness control of the remelted layer.
