CNC vertical lathe is a common CNC lathe. Its structure mainly includes the following parts:

1. Lathe bed (bed frame): The lathe bed is the main component of the CNC vertical lathe and is used to support and fix other components. The bed is usually made of cast iron or welded steel plate, which has high rigidity and stability.

2. Spindle box: The spindle box contains the spindle and spindle drive device, which is used to install cutting tools and drive the spindle to rotate for processing. The spindle box is usually located on the upper or side of the machine tool.

3. Workbench (workbench bed): CNC vertical lathe The workbench is the reference surface for workpiece processing and is used to install and clamp the workpiece. The worktable can move longitudinally along the bed to facilitate processing of long workpieces.

4. Crossbeam: The CNC vertical lathe crossbeam is connected to the upright column of the lathe to support and fix the moving parts of the crossbeam. It usually has high rigidity and stability to ensure processing accuracy.

5. Crossbeam moving parts: The crossbeam moving parts of the CNC vertical lathe include crossbeam guide rails, crossbeam sliders and crossbeam transmission devices, which are used to control the lateral movement of the crossbeam on the bed.

6. Spindle box moving parts: CNC vertical lathe. Spindle box moving parts include spindle box guide rails, spindle box sliders and spindle box transmission devices, which are used to control the longitudinal movement of the spindle box on the cross beam.

7. CNC system: CNC system is the control core of CNC vertical lathe, including CNC host, CNC device, programming device and operation panel, etc., which is used to control the movement and processing process of machine tools.

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

9. Cooling system: The CNC vertical lathe cooling system is used to cool the cutting area, prevent the workpiece and tool from overheating, and improve processing quality and efficiency.

10. Other accessories: CNC vertical lathes include tool magazines, automatic tool changers, fixtures, measuring devices, etc., which are used to improve the processing efficiency and flexibility of machine tools.

These components together form the structure of the CNC vertical lathe, achieving high-precision processing of the workpiece.
