With these machine beds in place, the night becomes his time to design a new type of machine.

The manufacture of some parts of the aircraft does not necessarily have to be on the five-axis machining center, and some extra-large parts require only the simplest high-precision lathe.

And what he is tackling now is this kind of large lathe, and 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 the design, it is necessary to consider the stable operation of the lathe, and it is this work that he is doing now.

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

As with the previous bed, these are materials that have been sitting for many years and are perfect for making machine tools.

High-precision machine tools do not mean that you can do it by finding a suitable material, the first thing to ensure is whether the stress inside the material has been completely released.

Otherwise, in a hurry, the result of the machine tool is to make the parts due to the existence of stress.

Over time, this can lead to significant inaccuracies and, in more severe cases, deformation.

These things are not compensated for by machining accuracy, even if the machining accuracy is high, it can't stop the deformation of parts.

Therefore, materials without stress have become an important condition for high-precision machine tool manufacturing.

There are many ways to release the stress of a piece of material, for example, he used a hammer to strike at a specific frequency to release the internal stress.

However, this method is generally not a good choice for high-precision machine tools.

Of course, the best way is to let the internal stresses disappear completely, but this method is also the most time-consuming.

If you want him to find such materials, don't look at the fact that he has some money now, but this kind of material is really not something that can 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 create a high-precision lathe.

It is also the simplest mechanical lathe, and there is no electronic control installed on it.

The lathe he is manufacturing now is what he intends to use to drive the keel of the fuselage of the aircraft, so it is inevitably large in size.

The first thing he had to do was to renovate the old bed, as well as slightly modify the structure to meet the needs of his newly designed lathe bed.

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

The most important components are the motor and the gearbox, which are important components to ensure that a lathe achieves the highest precision.

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

Enameled wire is the main material for winding the motor coil, and the enameled wire with consistent thickness, high material and thick insulating paint is a prerequisite for a good motor.

As for the wire, his eyes are vicious, especially the coils that are wound, and he has maintained a very high level of skill in key factors such as the number of turns, tightness, and tightness.

With these things as the base, the winding motor runs more smoothly than the high-end motor bought on the market, and there will be no vibration when rotating at low speed.

This motor is only a brushless motor, not a servo motor, to control the speed of the motor, as long as the voltage is changed, it can be achieved.

Therefore, this motor does not need to write control software, nor does it need to design circuit boards in hardware, so it can be said that this motor is the simplest motor.

The motor runs smoothly and there is no vibration, which is necessary to achieve a high-precision machine tool.

With the passage of time, after the electric motor was completed, he also manufactured other parts to be used on the lathe one by one.

Gearboxes, guides, spindles, air bearings, lead screws, etc., all parts are made in one step and made with the highest precision he can achieve in his hands now.

And after these things were made by him, they were packed into boxes full of cushioning materials and kept for later use.

After all the parts are manufactured, the lathe can also be transferred, and the parts he has made now have all reached the level of 0.05 microns.

After these parts have undergone a rigorous assembly process, it is not known what kind of machining accuracy can be achieved.

The assembly began, and in the dust-free workshop that had just been built, the lathe base, which had been renovated before, had already been moved into the workshop.

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

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

When his hand closed the electric switch and turned on the motor switch, the motor began to rotate.

The sound of the rotation was very small, and listening to the sound of the motor, he knew that it was a success.

Because it was exactly the same sound he had heard in the virtual lab, where the motor was turning.

The entire motor is designed, manufactured, and assembled by him independently, and the accuracy is controlled at the micron level, so the sound of rotation will show this faint appearance.

Resting his hand on the motor and feeling the faint vibration from the motor, all he expected.

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

The lathe has an accuracy of 0.5 microns, which is the highest accuracy he can build now.

With the success of the first one, the rest of the machines were faster, the first day took two months, while the others would not be so long.

Because with this lathe, the industrial workers who received it also came into use, and he handed over the rough drawings to these workers.

And he is responsible for finishing, as well as all kinds of high-precision work,

Under the sincerity of all the people, all the high-precision machine tool parts with a single function are all manufactured by them.

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

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

He added another item to his later work, which was to renovate the four machining centers to make them more accurate.

The parts that needed to be replaced, and it was at this time that the manufacturing began.

And when he was manufacturing these equipment, the Xiangshan County Air Show was also about to start.

This is the end of his manufacturing journey, and the rest of the equipment can only be continued after he returns from Xiangshan County.

Fortunately, at this time, no one from the Equipment Development Department came to give them an order to get off the plane, otherwise he would have to be broken into two pieces and used.

I gave these industrial workers some work, and handed over to 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 did not go with things, but went to Xiangshan County by plane, and the aircraft model and the 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 cumbersome procedures here.

They were taken to their outdoor exhibition area, a small but very well located place.

Then Guo Shugui played his role, began to contact the decoration company here, and began to arrange his exhibition area.

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

Just when they were arranging the exhibition area, the people from Hongdu Factory also came here, and this time it was Yan Hang, the old man, who led the team.

Their arrival also gave him acquaintances at the air show, and a place to visit the door, and the exhibition areas of the two companies were still very close.

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

One of the real machines is the strong five that the sword is ageless, and the second is the export-type powerful attack advanced trainer Falcon Eagle, and the model is the Sword UAV, which is still in the secret stage of stealth unmanned attack aircraft.

The exhibition area was decorated by the commercial art display company, and it looked very beautiful, and just when the decoration was almost complete, the things they brought from home finally arrived.

After the two aircraft models were in place, Li Zhenhua borrowed three people from Hongdu, and with the help of the three of them, the models were placed in place and assembled.

The cockpit is also being electrified, so that the people at the Hongdu factory will push the Suzaku 3 and Suzaku 8 stored there onto the runway.

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

The two planes, also under his control, took off from the Hongdu test flight site and flew towards Xiangshan County, Guangdong Province.

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

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

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

And the small plane that has landed now directly attracted the attention of everyone present.

I don't have a hatchback-sized plane, and it's still so peculiar in shape that it's hard not to attract attention.

The pomegranate pilot, who had just landed, had just climbed down from the plane and was standing on the runway stretching.

From time to time, I still pay attention to the planes that are about to land on the runway, and I want to see what new models will appear this time.

But when Suzaku 3 landed on the runway, the eyes of the Pomegranate Ji pilots widened.

"Huh? I didn't hear that this little thing was going to be exhibited!

When I took off on the carrier just now, wasn't this little thing still parked on the deck? ”
