I wonder if the machining you mentioned is rough machining? Or deep processing? Rough machining is to make semi-finished products to wholesale, and deep processing is to make semi-finished products to sell in stores. Rough machining has a small profit but a large quantity, and deep processing has a high profit but a small quantity. If both earn more money, rough machining will earn more, but it will also be much more tiring. At present, the market is quite good. I must eat anyway, at least I think so. I am a small shop opened by deep processing, and I can make a net profit of 8w- 10w a year. Looking for it in the master talent market, I don't know if it's good. I learned it at home.
