Re: [CAD_CAM_EDM_DRO] DRO intermitent fails

Hello friends,
Can give me somebody a hint:
Today I finished the reconstruction of a #2 TOS- mill.(checoslowakia)
Aligning the Mitsubishi-DRO-ruler I over traveled it.
First I got no readouts. After opening it and cleaning the ruler with
contact cleaner it worked only in the test by hand.
Later I had to readjust the spring and then it started to work
in one direction but sometimes in the other direction it fails to
count the travel. I suspect that there is still some oil on the
glass ruler or the reader doesn't travel right.
The amazing thing is that the readings do not fail on the same spot
and not always and there is an area of 25 cm where the ruler works
perfect.


I saw that the nests where the balls of the connecting rod sit, are
worn.
In the first moment I thought it could be fixed with light center point
hits in order to close the nests. (or some Epoxy)
Do you have better ideas or can I leave them like that?

Best regards
Sven Peter
