Hi,
As far as you own a CNC…
When I read above that “secure from above” has “PEMS” installed, I found this:
Ordering “secure from beneath” is exactly the conclusion I came to, but for another reason: I really prefer to secure from above. Putting my whole cnc machine in an upright position to put in screws from beneath is not at all an attracting idea to me. On the other hand, “Custom machine, drilling, counter boring” - what’s the problem if you have a cnc?
The point is if I order “secure from above”, I would have these “PEMS” (probably Swage Nuts) possibly with imperial threads. So I prefer ordering a bunch of Setzmutter “M 5” and put them into the QCW Frame myself (an thus I ordered “secured from beneath” version) in order to be able to use ordinary metric M 5 screws.
What aspect are you referring to?
