Various linear dimensions in very narrow flutes or grooves of an overall length of more than 400 mm require a high grinding input. Another challenge is to guarantee perpendicularity between the plate and axis. The tolerance for roundness is 0.005. Below is an excerpt from the inspection report. The features 8 through 14 relate to the roundness on the respective diameters.
Specified dimension | Tolerance | Actual dimension | Deviation | |
---|---|---|---|---|
