It is both a question of design and QC. The QC sheets that come with the asian imports are a joke. Some may actually meet it;
others won't.
The articles in HSM exist to help those like me that were ignorant or innocent enough to buy asian not really knowing the
difference.
It is too bad one cannot buy the bed, headstock and tailstock and then proceed to tune the stuff and add cnc.
Most of the rest disappears in a cnc conversion. Notice I didn't say anything about the carriage and crossfeed.
IMHO that simply needs redesigning.
Indeed I did not realize how bad my mill-drill was until after I had purchased a very used American built mill. Such is experience.

Not all asian is junk. Indeed some of the Japanese stuff is very nice, just pricey; which is why it is nice.
You pays your money and takes your chances.

Part of acceptability depends on use. Plastics and brass just don't put the same stress on a machine. It also depends on tolerances
and repeatability. One mans treasure is another's junk...or visa versa.
