The CNC lathe is composed of a bed, spindle, tool holder, feeding system, cooling system, and lubrication system, etc. 

The servo motor is used to drive the tool holder and table directly through the ball screw to realize the feeding motion.

The vertical lathe spindle is perpendicular to the horizontal plane and the circular table is used to clamp the workpiece. This type of machine is mainly used for processing large radial size and relatively small axial size of large and complex parts.
