Gleason’s new LeCount Type G Expanding Mandrel is based on our highly successful line of inspection mandrels.  The new Type G Twist Mandrel is bringing LeCount performance to a wider range of applications, particularly O.D. and face grinding operations where parts have a smooth bore and non-gear grinding process applications such as cylindrical grinding.
