Is it difficult to learn CNC machining center

[opi ci]

CNC machining center has complete functions and can complete the processing of multiple processes with high processing efficiency. The materials applicable to CNC machining center are mainly soft metals, engineering plastics and insulating materials. Soft metals include aluminum, copper and steel, and engineering plastics include PP, PA, PC, PA and reinforced polypropylene. CNC machining center is widely used in aerospace, agricultural machinery and equipment. So is it difficult to learn CNC machining center?

Is it difficult to learn CNC machining center?
If you are learning from the machine tool industry, it should not be difficult to learn CNC machining center, which mainly depends on your learning ability.

How to learn CNC machining center?
1. If you want to learn manual programming, you must have a certain mechanical foundation, so you must have Youji mechanical drawing ability, that is, you can understand drawings.
2. The second is to have the theoretical knowledge of interchangeability and understand the tolerance and accuracy of each part.
3. The third is to Youji the basis of machining and manufacturing process, be familiar with tool, some process criteria and processing sequence.
4. The problem of numerical control programming can only be raised to the problem of numerical control programming. At present, the workshop of numerical control programming is dominated by farlac system and Siemens system. Most foreign machine tools are generally Siemens system. Some domestic brands of equipment are farak system, which is basically connected. It is suggested to start with farak system, learn it all, and then learn Siemens system is very easy, Therefore, it is recommended to go to special schools and institutions for systematic learning. It takes a lot of time to learn the first few items alone. In addition, programming may not be as good as a year, plus on-the-job training.

What should be paid attention to before the operation of CNC machining center?
1. When entering the workshop, you should wear work clothes, tie the big cuffs tightly, and tie the shirt into your pants. Female students should wear safety helmets and incorporate braids into the helmets. 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 work together, they should pay attention to mutual coordination.
5. It is not allowed to use compressed air to clean the machine tool, electrical cabinet and CNC unit.
6. Practice on Zhiding’s machine tools and computers. Without permission, other machine tools, tools or electrical switches shall not be moved.

What are the preparations for the operation of CNC machining center?
1. Before operation, you must be familiar with the general performance, structure, transmission principle and control program of NC milling machine, and master the functions and operating procedures of each operation button and indicator light. Before understanding the whole operation process, do not operate and adjust the machine tool.
2. Before starting the machine tool, check whether the electrical control system of the machine tool is normal, whether the lubrication system is unblocked and whether the oil quality is good, add enough lubricating oil according to the specified requirements, whether each operating handle is correct, whether the workpiece, fixture have been clamped firmly, check whether the coolant is sufficient, then drive slowly and idle for 3 ~ 5 minutes to check whether all transmission parts are normal, After confirming that there is no fault, it can be used normally.
3. After the program debugging is completed, it can be operated according to the steps only with the consent of the instructor. It is not allowed to skip the steps. Those who operate without the permission of the instructor or operate in violation of rules and regulations will be given a zero score, resulting in accidents, will be punished according to relevant regulations and compensate for corresponding losses.
4. Before machining parts, it is necessary to strictly check whether the origin data of the machine tool are normal, and conduct Fangzheng operation without cutting track.
