No, nothing happened, I just want to know a little more.

What happens if I make a wrong instruction and, say, crash a spindle
into a vise. What would happen in reality? It is somewhere in the
range between "nothing special" and "explode in a giant fireball". So,
in reality, what happens if I crash a running spindle into a vise or
something of that sort. Would the mill be ruined permanently?
