Turning is mainly used to process various rotating parts. With the development of CNC technology, complex rotating shapes have become easier to achieve through programming, and CNC lathes can automatically change tools, greatly improving production efficiency.

The advancement of milling technology is one of the key factors in the rapid development of the manufacturing industry. From the initial ordinary milling machine to the three-axis machining center, and then to today's five-axis high-speed milling technology, milling makes it possible to process complex three-dimensional surface parts.
