It’s always been known that it is a single flank gear rolling tester that can measure transmission errors.　However, it is also true that those machines were not practical because materialized machine bodies were too big or too expensive.

Our newly-developed “SF-40NC” is completely different from those traditional testers. Its weight is less than twentieth from tenth and its price is less than fifth from half compared to conventional testers. SF-40NC is a computer numerical controlled (CNC) tester which achieved easy transmission error analysis with small size body and reasonable price.
