It took cycle times down from 18 hours with solid carbide endmills to 3 hours each part. We had to replace the safety plexiglass after every batch as it there would be "chips" melting all the way through it.
Our furnace retorts are made from Inconel. It's one of the few things that doesn't distort terribly after just a few runs (at over 2000°F for 16 hours, most items get a little soft or crispy). The price on those bad boys is crazy, for that reason.
