Hello Guys!
I've got couple questions I would love to hear some answers to. About 6/7 months ago I've took over 3 WEDMs at my new workplace , they were very poorly maintained and slowly but surely I'm bringing them back to former glory (mainly with lots of cursing and throwing wrenches at them, just kidding) but today one of them (FA20S - 2008 production) decided to fail me and completely lost pressure when threading the wire, I mean by that 0 pressure at lower and upper head. The water just drips like my tears.
My first guess is that a Solenoid valve has failed and its no longer supplying air pressure but its just a single guess and I would appreciate some more guesses/advices what can be the cause of this behaviour.
Also I'm finding a need to calibrate wire alignment on this machine preety often, by that I mean once a week. 80/85% of parts I make drown in tolerances of +/-0.01 mm and tighter and the usual U/V movement over the week hangs around 0.01-0.015 mm. Is it to be expected from 11 year old machine that was neglected ? Are there any remedies that I can use to counter that?
