Pivot Alloy
In Instruments, the clan of Pivot-Diamond-Anti-momnet Hairspring occupies large ratio. Pivot is the critical component in this family, which uphold such meters with Diamond Bearing. The Friction
Moment between Pivot and Diamond Bearing determines the Tolerance, Variation and Figure of Non-Back-to-Zero. Thus, Instrument Pivot is supposed to meet 3 requirements:
R1: The Geometry and Tolerance should conform to the condition that the Ovality is less than 0.**4 MM
R2: The Working Parts of Bearing is not allowed to have visible Stains, neither cracks, oxidization skins, etc
R3: The Dynam, Physical, Chemical Property of Pivot Alloy are supposed to conform to the requirement of Standard Loading, Working Conditions and Operation Life
