I am a technical secondary school student studying numerical control, but lathe workers, fitters and welders have to take one test, which proves that these three are better.

Of course, learning CNC is to take the CNC certificate. It's easier to take the intermediate certificate, but I personally think it's of little use unless I go to that place in the south where the certification doesn't recognize people. I'm from Pingdingshan, Henan, and our side mainly depends on people's technical level. No matter how many certificates you have, once you get on the lathe, you won't do anything, so the certificate is not important, but the technology is important!
