Hi Group

I`m hoping to setup a spindle for milling ferrous
and non-ferrous metals. I see a Bridgeport can
go do to 500 rpms. I`m not certain I`ll be able to
get down to 500 rpms. I was hoping to setup with
a 3450 motor, this would allow me to drive at higher
speeds for wood and possibly gear down to mill metal.
What are some typical cutter speeds for milling aluminum
and steel.

That's almost like asking 'How long is a piece of String' :)

That`s a great reference. I come from
a wood background. I didn`t realize all
that went into calculating speeds and
surface finish.
Thanks again
