According to Wilke, "This machine is designed for the precise measurement of our complex and large parts." Coordinate measuring machines have eliminated time-consuming coupling: with this process, many manufacturers still use gauges to identify the two rotors that fit to each other within the specified tolerances. Ever since GEA began measuring with coordinate measuring machines, each rotor in a line is the same as the next. Thanks to the measuring machines, ZEISS CALYPSO and GEAR PRO measuring software, the company now determines the source of errors at the push of a button and can initiate the elimination of problems wherever they may be. Wilke's summary: "As quality managers, we are now more than just checkers, we are knowers and controllers – and this makes our entire company that much stronger."
