Circumferential Backlash Instrument
These instruments measure the effective size of splines, while taking all form errors (effective spline) into account.
- Available for internal and external splines
- Composite spline, mutually rotatable discs
- Special measuring method that can be used instead of composite no go gauges according to ISO 4156 and ANSI B92.1
- Setting master required
Combination with Size Inspection Instrument
Combining the effective spline, as measured with this instrument, with the actual dimensions, that come from size inspection instruments, enables a more precise process monitoring. The FRENCO Software LdynPro determines the difference between actual and effective and offers important information with regard to the quality of the gearing.
