 You don't cut it you grind it!  If done on a lathe you turn the rubber
 part and run a high speed grinder against it.  It's insures it will be
 concentric and gives a smooth surface. 
In the workshops I've seen where it's handled, it's usually done with a
very sharp tool with a very acute cutting angle (I've seen razor blades
mounted in a holder for this) and lubricated with glycerine.

For some jobs, I've seen a tubular cutter (rather like a cork borer)
mounted in the tailstock and pressed into the workpiece, similarly
lubricated with glycerine.
