I've just done conventional. I'm guessing climb milling for finish is
more of a concern with an end mill.
Oh, no! If a large side mill digs in and pushes the table, it can easily
bend the arbor or cause other disasters. I think the larger the diameter
or the wider the width of the cut, the more dangerous a climb mill pass
can be. Id say ONLY if you have near zero-backlash screws should you
try climb milling on any heavy cut.



Thanks, DoN. This mill has a pump, but I suspect it used oil, sump
isn't very large, probably about a gallon. I doubt I'll use it. I
will use the old x-axis feed gearbox, just need the right belt.
If you do aluminum, coolant is great! The main aim is to keep the
workpiece cool. If aluminum heats up even a little, it becomes much
more tricky to cut. Not far at all between oil smoking a little and
the cutter becoming a huge glob of (workpiece) metal. And, of course,
DAMHIKT!
