	Actually ion-milling is the last step of the thinning process. Also, 
	once a sample has been properly thinned and used and then stored for 
	a while, one has to ion-mill it again before reusing, that way get 
	rid of the oxides and/or dirts that have accumulated during storage.

	However, inevitably one has to go through a sequence of polishing
	processes before s/he can put the sample in the ion-mill.
