The problems such as having serious wear still remains.Blisk another kind processing method is numerical control Electrolyzed Processing, Electrolyzed Processing there is also
The influence factor of some shortcomings, processing is more, and processing stability and repeatability are all poor, and it is whole especially to process enclosed
When leaf dish part, leaf dish runner bending moment and torsion complex, and fliud flushing problem also is difficult to solve.Current requirements are high, electrolyte and electrolysate
Need special disposal, environmental pollution serious.
