What is an inspector of machined parts? Is it dangerous? What is this?

Machining inspectors use vernier caliper, micrometer, depth gauge and other measuring tools to compare the processed parts with the drawings, mainly to detect whether the dimensions are out of tolerance and whether the appearance is wrong. Whether some specific technical requirements are qualified or not, there is no danger of flatness and roughness, but there will be no toxic gas, but the processed dust will have an impact on the body, but only slightly. In addition, there is only noise, and it is easy to work without testing. As long as you have a strong sense of responsibility and careful heart, there will be no danger. I hope you work well!
