Try running A2 die steel dry with carbide insertable then

( I dare you )

Yep. I like the Sandvik R390 insert. Run it dry and it puts all the
heat in the chip. Even 4140 comes off red hot. But I haven't got room
in my crowded home shop for full enclosures. So I just put up a piece
of sheet metal. At least for an HSM open machines make it easier to
work on oversize parts.

Now, I would like a tool changer. My lathes have one and its real
handy. Maybe someday for the mill.

Yep a tool changer would sure be nice. Probably never do it on the mini
machines, but I have an idea for the Hurco. Have a couple ideas that I need
to experiment with when the retro is done.

I made open top full enclosures for the mini mills. The Hurco will get a
fence enclosure on the table when I get everything else figured out.
Something that will set inside the outermost boundary of the table. Won't
be as good for spray, but then at a third the RPM it won't need to be.
