Please turn, milling, grinding and other workers to answer my questions.

I personally work as a mechanic.

There are mechanical aspects.

Turning, milling, boring, grinding and planing, but now the planer seems to be gradually included in the milling machine. The machine you mentioned for making taps and dies is not the type of machine I mentioned. Tapes and dies belong to cutting tools, just as the drill material we use belongs to high-speed tool steel, which cannot be processed by ordinary machines.

If it helps you, please adopt it.
