6. Advantages and disadvantages
The main advantages of ECM are :
machining of all conductive materials (ordinary and stainless steels, nickel- or cobalt-based refractory alloys, titanium-based alloys, sintered materials, etc.), regardless of their metallurgical state;
surface machining with high penetration speed, while obtaining a finished surface without metallurgical disturbance;
no roughing operation;
reproduction of complex shapes ;
drilling with very high depth/diameter ratios (< 200);
machining of thin walls by simultaneous machining of both sides of the part, e.g. for turbine blades;
absence of tool wear ;
easy control of machining...
