Precautions after NC lathe processing:

1. Remove chips, wipe the machine tool, and keep the machine tool and environment clean.

2. Pay attention to check or replace the worn oil friction plate on the guide rail of the machine tool.

3. Check the state of lubricating oil and coolant and add or replace them in time.

4. Turn off the power supply on the operation panel of the machine tool and the main power supply in turn.

5. When starting the machine tool, the principles of returning to zero first (except for special requirements), manual, inching and automatic shall be followed. The operation of the machine tool shall follow the principle of low speed, medium speed and then high speed. The operation time of low speed and medium speed shall not be less than 2-3 minutes. When it is confirmed that there are no abnormal conditions, the work can be started.

When it is confirmed that there are no abnormal conditions, the work can be started.

6. It is strictly prohibited to knock, correct and correct the workpiece on the chuck and between the centers. The next step can be carried out only after the workpiece and tool are clamped.

7. The operator must stop the machine when changing tools, workpieces, adjusting workpieces or leaving the machine tool.

8. The operator shall not disassemble and move the safety and protective devices on the machine tool at will.

9. Before the machine tool starts processing, the program verification method must be used to check whether the program used is similar to the processed parts. After it is confirmed that it is correct, the safety cover can be managed and the machine tool can be started for parts processing.

10. Machine tool accessories, measuring tools and cutting tools shall be properly kept, kept intact and in good condition, and shall be compensated for loss or damage.

11. After the training, clean the machine tool, keep it clean, move the tailstock and carriage to the tail of the machine, and cut off the power supply of the machine tool.

12. In case of any fault or abnormal phenomenon in the operation of the machine tool, it shall be shut down immediately to protect the site and report to the person in charge of the site immediately.

13. The operator is strictly forbidden to modify the parameters of the machine tool. If necessary, inform the equipment administrator and ask the equipment administrator to modify it.

14. Understand the technical requirements of part drawings and check whether there are defects in blank size and shape. Select a reasonable method of installing parts.

15. Correctly select CNC turning tools, and ensure the accuracy and firmness of installed parts and tools.

16. Understand and master the control and operation panel of NC machine tool and its operation essentials, accurately input the program into the system, simulate inspection and room cutting, and make various preparations before processing.

17. In case of abnormal running sound or failure of the lathe during processing, stop the lathe immediately for inspection and report to the instructor to avoid danger.
