Precision Spark Erosion Machining Machine Tool for Air Film Hole Spraying
In order to adapt to market demands and improve the performance of aircraft engines, as well as to meet the cooling effect of turbine blade film cooling, a precision spark erosion machine tool for film holes has been developed. 1. The same electrode is used for spark erosion processing of film holes with deep hole and bumpy hole structures. 2. The spindle mechanism for film holes meets the functions of high-precision rotation and automatic feeding of the electrode, high-pressure flushing of the inner hollow, high-pressure flushing of the outer ring electrode, electrode power supply and insulation, sealing of inner and outer high-pressure flushing, 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.
Ultra-fine CNC Electric Discharge Machining (EDM) Machine Tool
To meet market demands and achieve high-quality, high-precision, and high-efficiency manufacturing of micro shafts, micro holes, array holes, and micro three-dimensional structures, ultra-micro CNC electrical discharge machining (EDM) machines are under development. These machines can be applied in the fields of biomedical, electronic communications, MEMS, and other micro devices/micro molds. Main technical features and innovations: 1) Precision rotary feed peristaltic composite function spindle 2) Compact linear electrode discharge grinding mechanism for online production of micro electrodes 3) High-frequency micro energy pulse discharge power supply 4) Tangential feed linear electrode discharge grinding method for online production of micro electrodes 5) Innovative three-dimensional micro electrical discharge servo scanning processing technology 6) Depth precision control algorithm for micro three-dimensional structures 7) System integration of three-dimensional micro structure precision electrical discharge machining machines.
