As a basic and important metal processing equipment, lathes are widely used in many industries, mainly involving rotary cutting of metals, plastics and other materials. Among them, CNC lathes are the main choice for modern high-precision and complex shape processing, suitable for mass automated production industries. However, traditional lathes are still used for maintenance, small batches or teaching scenarios. Both have applications, but CNC lathes are more in line with modern needs. The versatility of lathes makes it a "working machine" in the manufacturing industry, covering almost all fields that require rotationally symmetrical parts processing.
