Stiff 1610 ballscrews, need help.... asap.

These are normally chemically reduced in size in a spinning contraption until they fall through the appropriate size hole. What chemical they would use i don't know but you would need to keep them spinning as not to loose shape and neutralise them with something suitable afterwards? What dissolves steel?

This experience let me understand what microns counts in precision mechanics.

I'm used to deal with nanoseconds, nanoAmpere, picoFarad and so on, sure i did not expect that a so small balls size gap could change coupling friction so deeply.

Sure, i have a lot to learn here ...

Hi to all,

the end of the story is the following:

i sent to Gary some videos showing ballscrews behaviour and following his suggestion, i will send back one ballnut.
