Operation points of CNC milling machine

1. When entering the workshop for practice, wear work clothes, tie the big cuffs, and tie the shirt under your pants. Female students should wear hard hats and put their braids in the hat. Sandals, slippers, high heels, vests, skirts and scarves are not allowed to enter the workshop. Note: It is not allowed to operate the machine tool with gloves;

2. Be careful not to move or damage the warning signs installed on the machine tool;

3. Be careful not to place obstacles around the machine tool, and the working space should be large enough;

4. If two or more people are required to complete a certain task, they should pay attention to mutual coordination;

5. It is not allowed to use compressed air to clean machine tools, electrical cabinets and NC units;

6. Internships should be carried out on designated machine tools and computers. Without permission, other machine tools, tools, or electrical switches, etc. must not be moved.

Folding preparations

1. Before operation, you must be familiar with the general performance, structure, transmission principle and control program of the CNC milling machine, and master the functions and operating procedures of the operation buttons and indicator lights. Do not operate and adjust the machine tool until you understand the entire operation process.

2. Before starting the machine tool, check whether the electrical control system of the machine tool is normal, whether the lubrication system is unblocked, whether the oil quality is good, and add enough lubricating oil as required, whether the operating handles are correct, and whether the workpieces, fixtures and tools are firmly clamped , Check whether the coolant is sufficient, and then drive a slow car idling for 3 to 5 minutes, check whether the transmission components are normal, and confirm that there is no fault before normal use.

3. After the program is debugged, it must be approved by the instructor to operate according to the steps, and skip steps are not allowed. Those who operate without the permission of the instructor or operate in violation of regulations will be treated with zero points for their scores. Anyone who causes an accident shall be punished and compensated for the corresponding losses in accordance with relevant regulations.

4. Before machining parts, it is necessary to strictly check whether the machine origin and tool data are normal, and perform a simulation run without cutting trajectory.

Precautions for the folding process

1. When processing parts, the protective door must be closed, the head and hands are not allowed to enter the protective door, and the protective door is not allowed to be opened during processing;

2. During the machining process, the operator is not allowed to leave the machine tool without authorization, and should maintain a high degree of concentration and observe the running state of the machine tool. In the event of an abnormal phenomenon or accident, the program should be terminated immediately, the power supply should be cut off and the instructor should be reported in time, and no other operations should be performed;

3. It is strictly forbidden to slap the control panel and touch the display screen hard. It is strictly forbidden to knock on the worktable, dividing head, fixture and guide rail;

4. It is strictly forbidden to open the control cabinet of the CNC system to watch and touch without permission;

5. The operator is not allowed to change the internal parameters of the machine at will. Intern students shall not call or modify other programs not compiled by themselves;

6. On the machine control computer, no other operations are allowed except for program operation and transmission and program copying;

7. CNC milling machines are large precision equipment. Except for tooling and workpieces placed on the workbench, it is strictly forbidden to stack any tools, clamps, blades, measuring tools, workpieces and other sundries on the machine tool;

8. It is forbidden to touch the knife tip and iron filings with your hands. The iron filings must be cleaned with iron hooks or brushes;

9. It is forbidden to touch the rotating spindle, workpiece or other moving parts by hand or in any other way;

10. It is forbidden to measure the workpiece, manual speed change during processing, and not to wipe the workpiece with cotton thread, nor to clean the machine tool;

11. It is forbidden to conduct trial operations;

12. When using the handwheel or rapid traverse method to move the position of each axis, be sure to see the ", -" signs in each direction of the machine tool X, Y, and Z before moving. When moving, turn the handwheel slowly to observe the direction of the machine tool movement before speeding up;

13. When the measurement of the workpiece size must be suspended during the program operation, the standby bed must be completely stopped and the spindle can be stopped before the measurement can be carried out to avoid personal accidents;

14. If the machine tool is not used for several days, the NC and CRT parts should be energized for 2-3 hours every other day;

15. When shutting down, wait for the spindle to stop for 3 minutes before shutting down.
