My experiment to see if I could electro-chemically machine Titanium.
In case you don't know, drilling/milling titanium using purely mechanical means is significantly difficult because it's such a tough metal.
After several failed experiments, this is the best I got. Not great results but it worked.
I used very salty water for fluid and a 48V/1000W power supply for power, and a low pressure circulating pump for water flushing.
The process does create scale on the surface which protects it from erosion, so I think maybe more waterflow would increase surface quality of cut.
More current also makes it cut faster, but it takes more voltage to get more current.
I tried a 5V 300A power supply and that did not work.
I also tried 48V with no flush, and that did not work because the quantity of gas produced at the electrodes prevents much action.
The titanium was all corroded looking so I buffed it up on my wire wheel.Report Video
