CNC vertical lathe is a kind of automatic processing equipment, which consists of multiple components. The following are the main components of CNC vertical lathe:

1. Main body of the machine tool: The main body of the machine tool of the CNC vertical lathe is a structural frame composed of a bed, a bracket, and a workbench. It provides the rigidity and stability of the machine tool and hosts the installation and movement of other components.
2. Headstock: The headstock is the core component of the CNC vertical lathe, including the spindle, spindle drive and spindle bearings. It provides the rotational movement of the spindle for cutting the workpiece.
3. Workbench: The workbench is a platform for placing workpieces to be processed, which can move up and down, rotate or tilt. It supports the fixing and positioning of the workpiece, and controls the movement track of the worktable through the CNC system to complete the processing operation.
4. Tool system: The tool system includes tool holders, tool holders, tool handles and tools, etc., for cutting workpieces. The tool system can usually realize the rapid replacement of various tools through the automatic tool change system.
5. Motion system: The motion system consists of a servo drive device and a slide rail, which is responsible for controlling the precise motion of each motion axis of the machine tool. Usually includes vertical (Z axis), horizontal (X axis) and lifting axis, etc.
6. Numerical control system: The numerical control system is the intelligent control core of the CNC vertical lathe, including the numerical control controller, servo drive, programming equipment and monitoring interface. It receives the input of the processing program, controls the movement of each movement axis, and realizes the precise processing of the workpiece.
7. Cooling and lubricating system: The cooling and lubricating system is responsible for providing cooling and lubrication to the tool and workpiece during cutting to reduce friction and heat, and protect the life and processing quality of cutting tools.

In addition, the CNC vertical lathe may also be equipped with measuring and testing devices, automatic workpiece loading and unloading devices, fixtures and safety protection devices, etc., to improve the accuracy, efficiency and safety of processing.
The above are the main components of CNC vertical lathes. Different manufacturers and models of CNC vertical lathes may have differences in details and configurations. Different industries and application fields have different requirements for CNC vertical lathes, and the appropriate configuration of CNC vertical lathes can be selected according to specific needs.
