A method of high-precision electrochemical machining (ECM) of turbine blades has been developed, which results in perfectly reproducible geometrical sizes of the parts with increased physical and mechanical properties, and in elimination of finishing operations and manual polishing.

ADVANTAGES OF ELECTROCHEMICALMACHINING

• Productivity for ECM is much higher than for mechanical or electroerosive machining.

• Machining of articles, which are difficult to be processed by mechanical machining.

• Machining of thin-walled and fragile articles.

• Manufacturing of details with complex geometry in a one-step process.

• High precision of machining (±0.01 mm) of tool and structural steels and of nickel-based heat resisting alloys.

• Machining and formation of a smooth surface are combined into a single process.
