Hey guys, I would like to hear from you what you think about this, please check the attached photos.
Micrometer on the photos is Mitutoyo with interchangeable anvils. Does this actually pass parallelism test?
Only way I can zero outside mics by myself is to place them on the stand, make sure they are vertical and place rod standard in between. Usually good anvils stand straight and flat against rod standard and they are repetitively on zero. But many are not, like the ones on the attached photos, you can move it around and get different measurements(which can be beyond our lab tolerance).
I sent few of those to two local vendors and they both are telling me that I cannot measure parallelism(which I am not, I am just setting zero) like that and they both claim that they pass parallelism test on their certs.
In my opinion, this is beyond calibration procedures and more of a common sense, as anvils are clearly bent and they shouldn't be used. My practice is to dispose them and get a new ones, but I changed so many of them that I need to question if I am doing the right thing.
Technicians on the floor who are using them are not taking good care of the tools and it is very likely when they try to measure components they are not really careful and gentle as they slam interchangeable anvil against component. That is at least my theory how they got bent.
There is over 500 techs across three shifts and talking to them individually is not an option.
