The economical solution for the complex machining of turbine blades Electro-chemical Machining (ECM) is the generic term used to describe various process variants. The ECM process manufactures workpieces through the electrolytic dissolution of metal. The process is used in the aerospace, automotive, medical, micro-system and energy industries. Almost all metals, even exotic materials such as nickel-based and titanium alloys or tempered materials can be easily machined using this process. The drawbacks of conventional metalworking, such as tool wear, mechanical stress, micro-cracking from heat input, oxidation coatings or subsequent deburring work do not occur with this non-contact machining process. ECM features material removal without any inherent stresses, soft transitions and smooth finishes.
