Wind power generation is very environmentally friendly, and the amount of wind energy is huge, so it is increasingly valued by countries around the world. A lathe is a machine tool mainly used for turning workpieces in rotation. The function of the lathe is to cut and process various rotating surfaces and helical surfaces of different sizes and shapes.
