Dear colleagues,
I'm going to polish a copper surface. We have a polisher but don't know how
to get a mirror like surface. Do you know:
1. How much is the size of powder/sheet can get mirror like polishing? Any
type? Al2O3 or something else?
2. I remember some liquid should be added during the polishing. What is that
liquid? Water? Is the liquid only for lubrication?
Thanks for your help,
Hongjun
