The structure of a CNC vertical lathe usually includes the following parts:

1. Main structure: The main structure is the bracket and bed of the CNC vertical lathe. It is usually made of cast iron or steel and has sufficient rigidity and stability to support the operation of the entire machine tool.

2. Spindle box: The CNC vertical lathe spindle box is the core component of the CNC vertical lathe, including the spindle, spindle drive device, spindle bearings, etc., and is responsible for realizing the rotational movement of the workpiece.

3. Workbench: The workbench is a component on a CNC vertical lathe used to clamp workpieces. It usually has an adjustable clamping device to ensure stable clamping and accurate positioning of the workpiece.

4. Tool rest: The tool rest is a component used to install tools on a CNC vertical lathe. It usually includes a tool rest seat, a tool rest slider, a tool, etc., and is responsible for realizing cutting operations.

5. CNC system: CNC system is the core control component of CNC vertical lathe, including CNC host, CNC operation panel, servo system, etc., which is used to control the operation and processing process of the entire machine tool.

6. Lubrication system: The lubrication system is used to provide lubricating oil to various moving parts of the CNC vertical lathe, reduce friction and wear, and ensure the normal operation of the machine tool.

7. Cooling system: The CNC vertical lathe cooling system is used to provide coolant to the tool and processing area, reduce the processing temperature, extend the tool life, and eliminate chips generated during the processing.

8. Electrical system: The electrical system of CNC vertical lathes includes the power supply system, control circuits, sensors, etc. of the machine tool, which is used to provide power and signal control to ensure the normal operation and control of the machine tool.

These components together form the structure of the CNC vertical lathe, which realizes the processing functions and CNC control of the machine tool.
