M43 means 390-800 rpm, and M43 means that the spindle is shifted to the third gear.
It is the high and low gear data of lathe. Depending on the machine tool, some are used to automatically shift gears, and some are used to tell the machine tool what gear it is in now.
1. Lathe is a machine tool that mainly turns rotating workpieces with turning tools. On the lathe, you can also use drills, reamers, taps, dies and knurling tools for corresponding processing.
2. The application of numerical control technology has not only brought revolutionary changes to the traditional manufacturing industry, but also played an increasingly important role in the development of some important industries (IT, automobile, light industry, medical care, etc.). ) of the national economy and people's livelihood.
3. At present, the development trend of CNC lathe is precision.
