How to Ensure Safety in CNC services or machining process?
Basic precautions for safe operation
1. When you enter the workshop for practice, you should wear work clothes, tie the big cuff tightly, and tie the shirt into your pants. Female students should wear safety helmets and put braids into the helmets. Sandals, slippers, high heels, waistcoats, skirts and scarves are not allowed to enter the workshop. Note: gloves are not allowed to operate the machine tool;
2. Pay attention not to move or damage the warning signs installed on the machine tool;
3. Pay attention not to place obstacles around the machine tool, the working space should be large enough;
4. When two or more people are required to complete a certain task, they should pay attention to the coordination between them;
5. It is not allowed to use compressed air to clean the machine tool, electrical cabinet and NC unit;
6. Practice should be carried out on designated machine tools and computers. Without permission, other machine equipment, tools or electrical switches shall not move disorderly.
Preparation before work
1. Before operation, you must be familiar with the general performance, structure, transmission principle and control program of CNC milling machine, and master the function and operation program of each operation button and indicator light. Do not operate and adjust the machine tool until you understand the whole 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 smooth and whether the oil quality is good, and add enough lubricating oil according to the specified requirements, whether the operating handles are correct, whether the workpiece, fixture and cutter are firmly clamped, and whether the coolant is sufficient. Then drive the machine slowly for 3-5 minutes to check whether the transmission parts are normal, After confirming that there is no fault, it can be used normally.
3. After the program debugging is completed, it must be approved by the instructor before it can be operated step by step. It is not allowed to skip steps. Those who operate without the permission of the instructor or violate the rules and regulations, and their scores will be dealt with as zero points, resulting in accidents, shall be punished according to the relevant regulations and compensated for the corresponding losses
4. Before machining parts, we must strictly check whether the origin of the machine tool and the tool data are normal, and carry out the simulation operation without cutting path.
Safety precautions in working process
1. When processing parts, the protective door must be closed. It is not allowed to stretch the head and hand into the protective door. It is not allowed to open the protective door during processing;
2. In the process of machining, the operator shall not leave the machine tool without authorization, and shall keep a high degree of concentration and observe the running state of the machine tool. In case of abnormal phenomenon or accident, the program operation shall be terminated immediately, the power supply shall be cut off and the instructor shall be informed in time, and other operations shall not be carried out;
3. It is strictly forbidden to tap the control panel and touch screen. It is strictly forbidden to knock the worktable, dividing head, fixture and guide rail;
4. It is strictly forbidden to open the control cabinet of the numerical control system to watch and touch without permission;
5. The operator shall not change the internal parameters of the machine tool at will. Interns are not allowed to call or modify other programs that are not compiled by themselves;
6. On the control microcomputer of machine tool, no other operation is allowed except program operation, transmission and program copy;
7. CNC milling machine belongs to large precision equipment. Except for the tooling and workpieces placed on the worktable, it is strictly forbidden to stack any tools, clamps, blades, measuring tools, workpieces and other debris on the machine tool;
8. It is forbidden to touch the blade tip and scrap iron with hands. Scrap iron must be cleaned with iron hook or brush;
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 and change the speed manually in the process of processing. It is also forbidden to wipe the workpiece with cotton yarn and clean the machine tool;
11. Trial operation is forbidden
