Dear MASists,
following the destruction (wearing out) of a 4 mm Stator (likely by a
series of badly equilibrated rotors (the last two lost substantial amount
of Zr oxyde) , the manufacturer suggest that we throw away any rotor with
visible black streaks ( about 25 of them) to start again on a safe basis
with the new Stator.
Is there an objective way of testing the quality of a rotor more
appropriate than a mere watching of gray traces ( Laser labelling also
appears as a gray trace!)
Would stable rotation be a criteria ?
Micrometric measurement with diameter tolerance ?
Can a rotor surface be repolished /machined ?
We are likely not the first with the problem but wet samples possibly
increase the risk with our applications.
Salutations Cordiales / Best regards / ;-)
