Securing millimeter sized part blanks to a machine tool for machining operations to sub micron tolerances is difficult, especially when these parts must be repositioned for additional machining, inspection, or other operations. The quick-flip locator1 fills the need for a part positioner that can be moved from one operation to another and returned while requiring minimal recentering. Furthermore it allows machining of two sides of a part with sub-micron registry without time-consuming re-centering operations.
