Why GSG on Cylindrical Plugs?

The inherent problem of centerless grinding is the three, five or seven point lobing which occurs during the grinding process. Most gage manufacturers simply roll lap the gage for size and finish. The appearance is good but the lobing is still present. GSG ring laps gages which removes lobing and produces a truly round gage which typically far exceeds the roundness specification. Longer Life: When is in use, contacting the part 360 degrees around the circumference of the gage rather than 3, 5 or 7 points gives the user longer gage life and confidence in your inspection process.
