Aluminium : Farily cheap, Soft, and fifficult to
machine well, it 'clogs'
the cutting tools
I haven't followed this thread until now. Not sure what it's about.
some aluminum-s machine quite well. I remember taking a cut on an aluminum faceplate on my
old Unimat 3
?(can't give any specifics, but it didn't seem that hard) and fine angel hair
shavings came off. I was using a brand new pre-cut German made cutting tool I'll point
out, and was turning at fairly high speeds.
?The stuff that turns best IMHO is stuff w/lead in it's content. Yellow brass, leaded
steel, etc. It "spits" the metal as opposed to creating continuous shavings.
It's has to do w/the way the lead adjoins other metals w/i the crystalline matrix.
?Ok I'm going back to sleep.
