Cleaning aluminum parts prior to peening - 10/10/06 07:48 PM
Dear Jack,
I am wondering what is commonly done to clean newly machined aluminum parts prior to shot peening?
Machining fluids contain surfactants for the purpose of adhering to a surface that dry to a film on the part that was machined. I have also observed that very small metal fines produced during deburring can often find their way to stick into the machining fluid film. These metal fines can resist considerable air blow off and still remain. Therefore the need is for a cleaning that dissolves the machining fluid residue, is friendly to our operators, accepts the metal fines, dries quickly, doesn't initiate corrosion or pit 2000 series aluminum, and leaves no residue of its own.
So with these details what cleaning fluid might be suggested? We are prepared to do some testing.
Thanks,
Anon
