Electrochemical Machining (ECM)
...aluminium and graphite are also used. Tool life is long compared with EDM and USM, since there is no appreciable tool wear. Tool material depends on component numbers, material and design, electrolyte composition and pressure, spark resistance, cost, etc. Most common electrolytes are sodium chloride (60–240 g l – 1) and sodium nitrate (120–480 g l –1), which...
