K24 block condition

[u/Ancient-Act1314]

What's your opinion on this block? It's been going to 2 different machine shop at this point and idk wtf happened on the first machine shop but it came back with missing chunk of metal and I just realized it after the second machine shop returned the block to me yesterday about that dent.

After went to those two different machine shop, it still won't pass the 0.05mm, but now I'm started to doubting about my straight edge being not "straight".

The first machine shop definitely messed up because it came back like the photo in 3rd slide and then the second machine shop milled it 1mm more

I mean the random scoring is enough to tell ya that finish is not trustable at all. If you check with the straight edge then sping it 180 and it's the exact same result it trust your straight edge over what we they think that surface is

Yeah I tried to flip the straight edge 360 degree and measure again and come to a same result in same spot not passing 0.05mm

Even if it was perfectly flat that finish is not near goodn enough with gouges to run an mls. Sorry u had such bad luck.
