Walking into the parts production workshop, you can see a completely different scene from the assembly workshop, where the workers stand in front of the machine and carefully process the workpieces on the machine tools.

Large parts of the aircraft, such as wing spars, fuselage frame segments, etc., require large-scale processing equipment.

There are no CNC machines, but there are still ways to do processing, but they just don't look very advanced.

Since we came to visit production, there was no reason to stop production and let Saudi Arabia and Pakistan come to see these cold machines.

On a gantry milling machine, the spar is being milled, and the milling cutter is driven by a motor to continuously remove excess material from the end face, typical of traditional metalworking.

I heard that a foreign customer came to visit the production, and the workers used their off-duty time to clean everything that could be cleaned, and the oil tank was cleaned up, and even the metal debris in the cracks in the ground was swept out.

The discerning people accompanying the base could see at a glance that this workshop had indeed put great effort into cleaning, and even the two people from the Ministry of Foreign Affairs had nothing to say, it was indeed much cleaner than when Yang Hui took them to see it a few days ago.

Watching the workers carefully align the knives, there are also automatic knife moves on the same side, all of which show the skilled skills of the workers and masters.

"What we see now is a metal parts cutting and forming workshop, and many of the parts made by our aircraft are processed by these machine tools, or that sentence, not the most advanced, only the most suitable."

Yang Hui's explanation can't be said to be a desperate one, but Sultan, who came to visit with him, couldn't help it anymore, this production line is too backward. Compared with my visit to the United States more than ten years ago, the production line of the F4 fighter is a little inferior, not to mention the current F15 production line in the United States.

It is no wonder that the aircraft produced by this republic are not comparable to those of Western countries. A glance at the whole picture can be seen, and for the first time, Sultan was a little skeptical about the introduction of the production line.

"This kind of production line is a bit backward. It seems that it is far from the international level, and I am afraid that it is not suitable for us to adopt such a production line. ”

What Sultan said was called unceremonious and hateful, but it was also true. The accompanying people can't refute it, your production line is not very good, aren't customers allowed to complain?

Perhaps feeling that the atmosphere of the scene was a little embarrassing, Madad came out at this time and acted as a concoctor.

"Prince, the main reason for this production line is that the machine tool lags behind the international advanced level. The degree of automation is not high, but this does not mean that the accuracy of processing technology is too far behind, and sometimes these workers use traditional machinery to process products that are not even lower than the accuracy of Western CNC machine tools. ”

That's right, after Madad explained this, Sultan and the base were both easy to talk to, so they nodded and continued, the project visit still has to be carried out.

Yang Hui also said a few words at the right time at this time.

"Madad is right, most of the accuracy of our traditional machining is no problem. Of course, if you want to talk about the kind of CNC machine tools in the West, we also have them in our base, but these are the three-axis and four-axis machining centers that will only be used in some high-precision machining. ”

Saying that, Yang Hui was going to go to the CNC machining center workshop on the other side, where the base was full of treasures.

Although it is only a three-axis and four-axis machining center. There is no such awesome artifact as the five-axis, but the current base is also a treasure of the town, and it is easy not to show people.

Walk into a building that is clearly different from other factories. From the outside, you can see that this workshop is different from the crowd, this is a new plant built by the base to install these CNC machining centers. It looks naturally different from the old Soviet-style factory built in the sixties, and there is already a trace of European and American elements mixed in it.

The team also felt that something was going to be different this time. Is this a core secret? It's a little exciting to think about.

Walking into the workshop, it is obvious that there is no such messy feeling when I visited other workshops just now, the equipment installation is neat and orderly, and even the workers responsible for production here are not few, more are some engineers wearing white clothes.

Now I found the feeling, this is what an airplane production line should look like, what does that dirty look like just now? Obviously too far behind.

It has already overlapped with the production line in his heart, and Sultan is satisfied: "That's right, it's what our Super Annihilation Seven and even the super seven-liter production line in the future should look like, okay, I think that's it." ”

After visiting for so long, I finally heard the praise from the foreign side, and Yang Hui and several other accompanying base leaders finally breathed a sigh of relief, it seems that this Saudi Arabia does not seek the most suitable, only the most advanced.

"Yes, Your Excellency, what we are seeing now is advanced CNC machine tools, and the degree of automation is already comparable to that of Western countries. You can see this four-axis machining center, which is machining special-shaped parts for our new engine after using our special tooling. ”

Following Yang Hui's words, in a small house-like shell, Sultan saw through the plexiglass window the parts being processed inside.

Several tools process parts at the same time, which is called machining center spindle linkage, which can effectively reduce the number of clamping times in the middle of the part from the beginning of processing to the final molding, so as to effectively control the error.

Several knives cut the parts at the same time, the coolant is poured on the workpiece being processed, and then splashes up, and at the same time, the fine cutting materials are constantly falling down, the whole machining process is all program control, there are no workers on the side to process with experience, it looks full of science and technology.

Sultan and Madad whispered, and then Madad was ecstatic, Yang Hui saw that he vaguely guessed something here, and began to calculate in his heart.

Sure enough, after talking to Madad, Sultan continued to announce: "I think such a production line is very good, and our production line and Pakistan's production line should also reach at least 80% CNC machine tooling, which is a must, a hard rule." ”

Sure enough, since the local tyrants have spoken, where do we have no reason, as long as people are willing to give money, we will do what they say.

Numerical control, that simple as long as you give money is easy to say, now the Republic, Saudi Arabia, Pakistan and Western countries have a good relationship, the purchase of these high-end processing equipment, as long as it is not a five-axis high-end to no product, there is not much problem in giving enough money.

Of course, with such a high degree of numerical control, the efficiency of natural production is not the same.

It is necessary to know that the production efficiency is high, and there is little intervention by human factors, which is the biggest advantage of CNC machine tools, and I am afraid that with the order of Pakistan and Saudi Arabia, I am afraid that it can only maintain the operation of the production line for ten years.

When the time comes, either Saudi Arabia and Pakistan will increase purchases, or the production line will be mothballed, it's as simple as that. Now Saudi Arabia can't see this, and Yang Hui doesn't bother to remind him that the local tyrants have money, and they will be sealed and sealed.

Yang Hui won't say this, haven't you seen anyone in Pakistan and didn't speak? Now Yang Hui needs to consider how many CNC machine tools the base can use this opportunity to add to the base.

Let's do the math first, the three axes seem to be a bit chicken now. Well, take advantage of this opportunity to buy more four-axis machining centers to come back, there are also some special machine tools for the aviation industry, this time to find an opportunity to see if you can get back one or two that is the best.

Thinking of these benefits, Yang Hui felt that there was no reason not to agree, this kind of thing that benefited others and himself was the best.

"There is no problem, it can be done, as long as this production line is needed, we will use CNC machine tools, 80% of the use rate of CNC machine tools, we can do it." (To be continued......)
