Precautions when operating CNC vertical lathe include:

1. Before entering the CNC vertical lathe CNC vertical lathe operation room, you must wear suitable work clothes and a work cap, and ensure that the shirt is tied into the trousers, open sleeves should be tied tightly, and long hair should be included in the cap.

2. It is strictly forbidden to wear gloves during operation, and ensure that the collar and cuffs of the work clothes are fastened.

3. Before starting the CNC vertical lathe, you must check whether the chuck wrench has been removed and ensure that the machine tool speed change handle is in the correct position.

4. When the various mechanisms of the CNC vertical lathe are operating, the handles must not be changed. If you need to change the handle position, you must do it after parking.

5. CNC vertical lathes are prohibited from touching the rotating spindle, workpiece or other moving parts with hands or other means. It is also prohibited to install or remove tools while the spindle is rotating.

6. Tools used to clamp workpieces and adjust tools in CNC vertical lathes are prohibited from being placed on the machine tool guide rails.

7. It is forbidden to touch the tool tip and iron filings with your hands on CNC vertical lathes. You should use brushes and hooks to clean them.

8. During the automatic processing of CNC vertical lathes, it is prohibited to open the machine tool protective door.

9. Before operating the CNC vertical lathe, ensure that all parts of the machine tool, such as the bed, spindle, feed transmission, etc., are operating normally.

10. CNC vertical lathe selects the appropriate tool according to the workpiece requirements, and selects the appropriate process parameters according to the workpiece material, such as spindle speed, feed speed, etc.

11. Before operating a CNC vertical lathe, you should be familiar with and understand the structure and performance of the machine, lubricate the machine, and clean certain components to ensure smooth oil passages.

12. CNC vertical lathes are large-scale mechanical equipment. Special attention should be paid to the safe placement and fixation of workpieces to avoid accidental injuries caused by improper placement or weak fixation of workpieces.

13. During the processing of CNC vertical lathe, the operating status of the machine tool must be monitored, paying special attention to the position of the tool during feed and retraction to ensure the safety and stability of the processing process.

Following the above precautions can ensure the safety and efficiency of CNC vertical lathe operation and reduce accidents and losses caused by improper operation. At the same time, it is also recommended to perform regular maintenance and upkeep on machine tools to extend their service life and improve work efficiency.
