First, the basic precautions for safe operation
1. Please wear overalls and safety shoes when working, otherwise you are not allowed to enter the workshop. The shirt should be tied into the trousers, and the overalls, collars and cuffs should be fastened. Do not wear sandals, slippers, high heels, vests, skirts and scarves to enter the workshop to avoid burns. It is forbidden to operate the machine with gloves. If you have long hair, wear a hat or hair net.
2. All experimental steps must be carried out under the guidance of the training teacher. The machine is not allowed to be activated without the consent of the instructor.
3. It is strictly forbidden to leave the job during the operation of the machine to do things that are not related to the operation. It is strictly forbidden to play and fight in the workshop. When the machine is started, it is strictly forbidden to shuttle between machine tools.
4. Internships should be conducted on designated machine tools and computers. Other machine tools, tools or electrical switches must not be tamper-proof without permission.
5. If a job requires two or more people to work together, you should pay attention to the coordination between each other.
6. Before the start-up, the CNC lathe should be thoroughly and carefully checked, including the operation panel, guide surface, claws, tailstock, tool holder, cutter, etc., and the operation can be confirmed after confirmation.
Second, preparation before work
7. Before the machine tool starts working, it must be preheated, and carefully check whether the lubrication system works normally. If the machine tool has not been started for a long time, it can be manually lubricated to all parts.
8. Before the instructor confirms that the procedure is correct, the “machine lock†status button that has been set on the operation box is not allowed.
9. Tighten the workpiece: Ensure that the workpiece is firmly fixed on the workbench.
10. Remove the adjustment tool: Before starting the machine, check whether the wrench, wedge and other tools have been removed from the machine.
Third, the safety precautions in the work process
11. After the CNC lathe is energized, check whether the switches, buttons and buttons are normal, flexible, and whether the machine tool is abnormal.
12. After the program is entered, you should carefully check the code, address, value, sign, decimal point and syntax.
13. Correctly measure and calculate the workpiece coordinate system and check the results.
14. Enter the workpiece coordinate system and carefully check the coordinates, coordinate values, positive and negative signs, and decimal points.
15. Before the workpiece is installed, run the program once to see if the program can be carried out smoothly, whether the tool and fixture are installed properly, and whether there is overtravel.
16. The quick override switch must be hit to the lower gear when the test is cut.
17. When the cutting is started, the tool must be moved to the workpiece 30-50mm, and the Z-axis and X-axis coordinate residual values ​​must be consistent with the machining program under the feed hold.
18. In the trial cutting and machining, after sharpening the tool and replacing the tool, it is necessary to re-measure the tool position and modify the tool compensation value and the tool compensation number.
19. After the program is modified, it is necessary to check the modified part carefully.
20. The machine must be started after confirming that the workpiece is clamped. It is strictly prohibited to measure and touch the workpiece while the workpiece is rotating.
21. In case of abnormality such as workpiece jumping, shaking, abnormal sound, and loose clamp during operation, it must be stopped.
22. After the emergency stop, the machine “return to zero†operation should be performed again to run the program again.
Fourth, the precautions after the work is completed
23. Clear the cutting and wiping machine, and keep the machine and environment clean.
24, pay attention to check or replace the oil wiper on the machine tool rail damaged by the mill;
25. Check the status of lubricating oil and coolant, and add or replace them in time;
26. Turn off the power and main power on the machine's operation panel in turn.
