I have worked in the precision instrument industry for many years. According to my understanding of the domestic precision instrument industry, the domestic precision instrument industry is still in a very primary and simple imitation state, far from the number of patents and instruments advertised by some companies. Suggestion: Do some in-depth research on precision motion control technology and optical imaging measurement technology. For example, in the current optical measurement industry, an experienced hardware drawing engineer has a monthly salary of 89,000 yuan, and there is more room for self-employment.
