What's the job like as a mold lathe worker?

Numerical control lathe is a little simpler than ordinary lathe. As far as danger is concerned, scratches, scalds and pricks are common, but it is normal to do things, so don't take it to heart.

I suggest you get used to it first, but if you can't stand it, change to something else.

Anyway, work? That's it.

You will know when you are dirty and tired. You can't say that. How long you study depends on your comprehension. If you want to learn essence, 1 2 years is the least. Mold design can be said to have nothing to do with this, but you can understand how they are designed by looking at the drawings.
