Yeah, pretty much. I've heard that you can retrofit high speed spindles on machines, but it's much better if it's designed in.
Tool life generally decreases with increased speed. But back in the day, some wiseapple discovered that if you go
very fast the tool life is also acceptable (with lighter cuts).
One big advantage is that cutting forces are pretty low with HSM, so fairly frail parts can be made with the process.
