Super Weapon Swap System

Large CNC milling machines are running, and countless blades are rotating flexibly, drawing beautiful arcs on many shaft surfaces.

The blade is constantly moving. At the same time, the workpiece is also rotating inside. A long copper wire is cut out, and the copper wire extends outward, just like a naughty wild cat playing with a thread ball.

Inside, the shape of each blade is gradually displayed. However, the shape of this blade is particularly large. This is a super marine propeller with a diameter of five or six meters!

At the beginning, it was a whole piece of copper. Only copper alloy can become a qualified propeller.

After all, the propeller operates underwater, and the sea water is salty and corrosive. To adapt to the long-term operation in the highly corrosive environment of sea water, pure steel can not be used, because it can not withstand long-term corrosion, only a special copper alloy can be used. Pure copper is soft, which is also the material of cartridge case. If manganese, nickel and other metals are added to copper, The rigidity of the alloy can be improved, which can meet the needs of the propeller.

The casting of a whole copper block is a difficulty. However, the later processing is more difficult. The propeller is a complex curved surface. If you use an ordinary milling machine to operate, first process one surface and then process another surface, you have to change the fixture. When changing, there will be an error. Although the error is small, for the propeller that strives for perfection, It is enough to have a fatal impact. It will increase underwater noise, especially for submarines, which must be kept silent.

Fortunately, with this advanced CNC machine tool, multi axis linkage, after the copper block is fixed, it will no longer move. The turning tool rotates on multiple shaft surfaces and gradually cuts a copper block into the shape of a propeller.

It takes three days to cut a huge copper block into a propeller, which is very fast. When there was no such processing equipment before, it took more than 30 workers and half a month to cut a small propeller, and the accuracy can not be guaranteed.

The propeller used for submarine is multi blade and large side inclined. Now it can be seen. It is like a Turkish machete. Now it is processed with nine blades, with a total weight of hundreds of tons!

"OK, processing is finished!" finally, among the metal debris all over the ground, the machine tool stopped moving, and the propeller is finished!

"Wait, there seems to be something wrong?" just as preparing to transfer the propeller, a worker shouted, "why is its surface so rough?"

After the propeller is processed, the surface is extremely smooth. These are for the purpose of reducing noise. Now it becomes rough. Can't you polish it? Of course not. A little manual polishing will certainly not maintain the original balance, which will increase the vibration.

The foreman is also confused. Is there a problem with the turning tool in the processing process? No, the turning tool has been reground. It's absolutely no problem.

"Its shape is also unqualified!"

The processing of propeller is quite precise. Professional instruments are used to detect whether the shape is qualified, but now, professional workers can see that there is a problem with its shape with the naked eye. The bend of the end machete is too direct, which is not the style at the time of design!

"Our processing is in vain. It's a waste." the foreman's face suddenly became very ugly. The propeller was cut out with hundreds of tons of copper blocks. Now, all of them are scrapped!

How did this happen?

"Immediately find an engineer, find an engineer to check!"

Soon, Xiong Guo's engineers came to check. They checked inside and outside for countless times and vowed that there would be no mistakes.

As a result, the copper block was clamped again and began to cut. The shape was even more amazing, and the propeller became an 8-shape! The error is even greater!

Everyone is pale. This has never happened before. What does this mean? The failure of the machine tool is too big. We must find the manufacturer to repair it!

"Contact the Han side and ask them to repair it!"

For submarines, the mute performance comes first. The most noisy one is the propeller. It rotates and directly contacts the sea water. The sound of stirring the sea water spreads far. Therefore, Xiong Guocai spent a lot of effort and introduced this processing equipment to reduce the noise at once.

Now, this kind of machine is broken and can't be used!

The same situation is happening elsewhere.

The key to the processing of flat slot radar antenna is the position and size of the slot, which must be completely accurate. Xiong Guoren can't process it because they can't accurately open the slot.

It's just a crack. Is it difficult?

Of course, it's not difficult to carve a crack on the board. How about carving a crack on the dough? Carve a gap in the insect's wings and try it? The most difficult waveguide component layer has large size, high precision and complex structure, and there are a large number of weak stiffness structures such as thin wall, ultra-thin web and micro through slot. The biggest problem is that it is easy to deform and the accuracy is difficult to guarantee.

You can slot, but when you slot, you immediately destroy it. This kind of fine work is the least good at Xiong Guoren.

Now, the Han state has provided them with a complete production process, and the Han people have produced a completely qualified flat panel antenna with this set of equipment!

A thin turning tool went down and cut the gap. After cutting, I saw a shallow mark left on it, which was not cut through at all!

"Increase strength!"

The second time, finally, the turning tool suddenly penetrated the layer of film made by the salt bath process. At the moment when the turning tool cut the gap, the whole film layer was driven up, just like a layer of window sashes.

"Damn it, what's going on?"

On the production line, there are all kinds of attempts, but no matter what they do, they can't process qualified products! If they want to continue production, they have to ask Han people to debug them!

All departments, which need the equipment provided by the Han country to operate, can not produce normally now. At this time, they finally realized that this scene was not accidental, nor was it their own engineers' carelessness, but the Han people must have tampered with these equipment!

Xiong Guoren suddenly became confused. They thought they didn't need Han people. They could raise the price to pit Han people. After all, Han's industry has not developed for a long time, and there are still many things that can't be produced by themselves. Han people have to accept more money. How can you know that Han people have no response on the surface, but secretly disabled all these things!
