Machinist has never seen finish marked this way





September 13, 2010

Hello, I am looking at a pc. of 52100 1/4" thick ,16"X 11" I do know it is for testing of plastic's . It spells out a finish of Rz 1 µm to 1.5 µm ( The you looks more backward though with the drop of the you being lower on the left side ) I can not duplicate the you the way it is shown here ! Any help would be much appreciated .
Thank You Very Much

Hi, Burl.

That's the greek letter "mu" in lower case and it means "micro" or "millionth". They apparently are looking for an Rz 1 to 1.5 micrometer (micron) finish.
