Hi,
This is my first post. I recently purchased a mill (Chinese) and have spent several days rebuilding it :-). My initial use for the machine will be milling 1-2mm aluminum plate and hopefully Circuit Boards.
After trial and error I have the machine cutting the aluminum (not melting it :-)) but still not with the finish I would like. I have attached some pictures and would love comments. You will see I added a air brush as a mist coolant which seems to work well with a mix of kero and cutting oil.
The machine specs are
1200mm x 800mm bed
2kw water cooled vfd.
mach3
The best cutting I have done so far is 6000rpm 200mm/min 15mm/m plunge with a 3mm, two flute slot drill. but still not great.
I believe that my vfd can do 12000rpm but at that melts not cuts.
Please advise.
Matt
