Pitch Blade Turbine 3.5''

Standard Mill Finish

A finish that is unimproved after machining or processing and can look dull, grainy, or rough.  Welds are wire brushed to remove discoloration.  Additionally, welds maintain their irregular form as created by the welding process; they are not blended nor ground smooth.

32Ra Food Grade Finish

A finish that is mechanically polished to a minimum sanitary level often found in food service.  Equivalent to a #4 finish or 180 grit abrasive finish.  Surface may be dull, but is smooth.  Welds are ground smooth to match surface polish of the rest of the part.

20Ra Pharma Finish

A finish that is mechanically polished to a minimum sanitary level often found in pharmaceutical service.  Equivalent to a #4 “high grade” finish or 220 grit abrasive finish.  Surface will show some sheen, but may be wavy when held to light.  Welds are ground smooth to match surface polish of the rest of the part.

8Ra High End Pharma Finish

A high end finish often found in stringent pharmaceutical service.  Equivalent to a #7-#8 finish or 400 grit abrasive finish.  Surface will have sheen, and very faint waviness when held to light.  Part may not have a high luster shine, as Fusion does not polish with animal fat based compounds.  Welds are ground smooth to match surface polish of the rest of the part.
