On these chinese linear bearing rails, are the boltholes drilled in two
ops. the shcs hear socket, then the bolt hole on thru, or with a custom
cutter all in one step?
My probe is a 12 gauge copper wire, spinning at 300 revs in the spindle
and might have enough tip wobble to prevent it from descending into the
3mm bolt hole to actually measure the bolthole so I may have to settle
for centering in the SHCS counterbore. And assume the bolthole is
centered in the SHCS clearance. My experience has been they're a lot
sloppier at the bolt hole locations than in bearing precision which is
pretty good.
What is your experience in similar situations?
Cheers, Gene Heskett, CET.
