Chapter 159 Kyushu Aircraft Exhibition

With those machine beds in place, the nights turned into his time designing new machines.

The manufacture of some aircraft parts does not necessarily require a five-axis machining center. Some very large parts only need the simplest high-precision lathe.

And what he is working on now is this kind of large lathe. It is not too difficult to make a lathe.

But if you want to make a high-precision lathe, it is not an easy task.

First of all, in terms of design, it is necessary to consider the stable operation of the lathe, and what he is doing now is exactly this aspect of work.

A few days later, the materials he asked for from Minister Wang also arrived. These are special steels that have been placed for more than three years. As for where they were transferred, it has little to do with him.

The same factors as the previous bed, these are materials that have been sitting for many years, and they are perfect for making machine tools.

High-precision machine tools do not mean that you can start with just a piece of suitable material. The first thing to ensure is whether the internal stress of the material has been completely released.

Otherwise, the result of making the machine tool in a hurry is that the parts produced are due to the existence of stress,
Over time, it can lead to serious inaccuracies and, in severe cases, deformation.

These things cannot be compensated by the machining accuracy. No matter how high the machining accuracy is, it cannot stop the deformation of the parts.

Therefore, materials without stress have become an important condition for the manufacture of high-precision machine tools.

There are many ways to release the stress of a material. For example, he used a hammer to hit it at a specific frequency to release the internal stress.
However, this method is generally not a good choice for high-precision machine tools.

The best way is of course to let it stand naturally, so that the internal stress can completely disappear, but this method is also the most time-consuming.

Let him find such materials, even though he has some money now, but this kind of materials really cannot be solved with money.

Now that the materials are in place, the lathe can be manufactured.

Find the largest one from the many old lathe beds, and he will use this lathe bed to build a high-precision lathe,
It is also the mechanical lathe with the simplest structure, and there is no electronic control installed on it.

The lathe he is making now is intended to be used for turning the keel of the aircraft fuselage, so it is inevitably large in size.

The first thing he has to do is to renovate the old bed and slightly modify the structure to meet the needs of his newly designed lathe bed.

There are many parts on a lathe, and the lathe must have sufficient precision to maintain high-precision operation.

The most important thing is the motor and the gearbox. These things are important components to ensure that a lathe can achieve the highest precision.

After he finished remodeling the bed of the lathe, he started to manufacture the machine tool starting with the motor.

Enameled wire is the main material for winding motor coils, and enameled wires with consistent thickness, high-quality materials, and thick insulating varnish are the prerequisites for winding out a good motor.

As for the wire material, his eyes are vicious, especially the coils that are wound out have maintained extremely high skills in key factors such as the number of turns, tightness, and tightness.

With these things as the foundation, the wound motor runs more smoothly than the high-definition motors bought in the market, and there will be no vibration when rotating at low speeds.

This motor is just a brushless motor, not a servo motor. To control the speed of the motor, just change the voltage.
Therefore, this motor does not need to write control software, nor does it need to design a circuit board on the hardware. It can be said that this motor is the motor with the simplest structure.

The motor runs smoothly without vibration, which is a necessary condition for achieving high-precision machine tools.

As time went by, after the motor was made, he also manufactured other parts used on the lathe one by one,
Gearboxes, guide rails, spindles, air bearings, lead screws, etc., all parts are completed in one step, with the highest precision that he can achieve now.

And after these things were manufactured by him, they were packed into boxes filled with cushioning materials and kept for later use.

After all the parts are manufactured, the lathe can also be transferred. As far as the parts he manufactures now, all of them have reached the level of 0.05 microns.
After these parts have undergone strict assembly process, it is not known what kind of processing accuracy can be achieved.

The assembly started. In the newly built dust-free workshop, the lathe base, which had been remodeled before, had been moved into the workshop a long time ago.

In this dust-free workshop, he took the parts out of the box one by one, and after cleaning each part, he began to assemble it on the bed.

A complete lathe, after his unremitting efforts, was finally built by him after one and a half months.

When his hand closed the switch and turned on the motor switch, the motor started to rotate,

The sound of rotation was very small, and he knew it was a success when he heard the sound from the motor.

Because this sound is exactly the same as the sound of the motor rotating that he heard in the virtual laboratory.

The whole motor was independently designed, manufactured, and assembled by him, and the precision was controlled at the micron level, which is why the sound of turning is so weak.

Putting his hand on the motor, he felt the faint vibration from the motor, all of which were within his expectations.

This lathe took him two months, and it really didn't waste his energy.

The precision of this lathe has reached 0.5 microns, which is the highest precision he can create now.

With the success of the first machine, the speed of the rest of the machines, the first day took two months, while the others will not take so long.

Because with this lathe, the industrial workers he received will have a place to use. He handed over the rough blueprints to these workers,

And he is responsible for finishing and various high-precision work,

Thanks to the sincerity of all, all high-precision machine tool parts with a single function were manufactured by them.

The rest of the work was assembly, and before he had time to assemble, the large five-axis machining center that Minister Tuo Wang bought finally arrived.

There are four in total, two vertical and two horizontal.These four machining centers are domestically produced, and their machining accuracy is not very high, and of course it is not low, but relatively speaking, they cannot reach the high precision level.

He added another item to his later work, which was to transform these four machining centers to improve their machining accuracy to a higher level.

The parts that need to be replaced are also manufactured at this time.

When he was manufacturing these devices, the Xiangshan County Airshow was also approaching.

His manufacturing trip this time has come to an end, and the remaining equipment can only be made after he returns from Xiangshan County.

Fortunately, at this time, no one from the equipment development department came to place an order for them, otherwise he would have to be broken into two pieces to use.

I gave some work to these industrial workers, and gave them the rough processing of the parts they needed.
After arranging all the company's affairs, he, Li Yun, and Guo Shugui set off with the cockpit and the empty shell models of the two planes.

The three of them didn't go with things, but went to Xiangshan County by plane, and the plane model and cockpit were transported by land.

The three of them came to the organizer of the air show, Xiangshan County Air Show Company, and went through a series of tedious procedures here.
We were taken to their outdoor exhibition area, a small but well-located place.

Then Guo Shugui played his role, contacted the decoration company here, and started to decorate his exhibition area.

With Guo Shugui here, he doesn't need to worry about these trivial matters, and now he is just waiting for the arrival of the cockpit.

Just as they were setting up the exhibition area, people from the Hongdu factory also came here, and the old man Yan Hang led the team this time.

Their arrival also allowed him to have acquaintances at the air show and a place to visit, and the exhibition areas of the two companies are still very close to each other.

After Yan Hang's people arrived, they also started to decorate the exhibition area.There are three types of models they exhibited this time, including two real models and one model.

One of the real machines is the everlasting Qiang Wu, the other is the export-oriented high-strike advanced trainer Falcon, and the model is the Sword UAV, a stealth unmanned attack aircraft that is still in the secrecy stage.

The exhibition area was decorated by the Commercial Beauty Chen Company, and it looked very aesthetic. When the decoration was almost finished, the things they shipped from home finally arrived.

After the two aircraft models were in place, Li Zhenhua borrowed three people from Hong Du. With the help of the three, they put the models in place and assembled them.

The cockpit was also powered on, and the people at the Hongdu factory pushed the Suzaku 3 and Suzaku 8 stored there to the runway.

Then he went through the normal procedure, applied for the route, and got into the cockpit by himself.

Under his control, the two planes took off from the Hongdu test field and flew towards Xiangshan County, Guangdong Province.

The distance between the two places is just within the range of the plane, but it is just enough fuel to land.

The first to land on the air show runway was Suzaku 3, a small aircraft only 3.5 meters long.

And the runway here is also busy, and the models exhibited by various companies will land on this runway.

And the little one that landed now directly attracted the attention of everyone present.

There is no plane with the size of a hatchback, and its shape is still so peculiar that it is difficult not to attract attention.

The Flying Shark pilot who just landed, just climbed off the plane, was standing on the runway stretching his body.

From time to time, he kept his eyes on the planes that were about to land on the runway, wanting to see what novel models would appear this time.

But when Suzaku 3 landed on the runway, the Flying Shark pilot's eyes widened.

"Huh? I didn't hear that this little thing will also participate in the exhibition!
When I took off on the flight mother just now, wasn't this little thing still parked on the deck? "
