Start with a blacksmith shop

With these machine beds in place, nights became his time to design new machine tools.

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

What he is currently working on is this 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 the design, the stable operation of the lathe must be considered, and this is exactly what he is doing now.

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

The same factors as 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 just find a suitable piece of material. The first thing to ensure is whether the stress inside the material has been completely released.

Otherwise, the result of making the machine tool in a hurry will be that the parts produced will be damaged due to the existence of stress.

Over time, it will lead to serious inaccuracies and, in more severe cases, deformation.

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

Therefore, stress-free materials have become an important condition for the manufacturing of high-precision machine tools.

There are many ways to release stress in a piece of 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 sit naturally to allow the internal stress to completely disappear, but this method is also the most time-consuming.

If you want him to find such materials, even though he has some money now, this kind of materials really cannot be solved with money.

The materials are already in place, so the lathe can start manufacturing.

He would find the largest one among the many old lathe beds, and he would use this lathe bed to build a high-precision lathe.

It is also the simplest mechanical lathe with no electronic control installed on it.

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

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

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

The most important ones are the motor and gearbox. These are important components to ensure that a lathe can achieve the highest accuracy.

After he finished modifying the lathe bed, he started with the motor and started building the machine tool.

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

As for wires, his eyes are ruthless, especially the winding coils, which maintain extremely high skills in key factors such as the number of turns, tightness, and tightness.

With these things as the base, the wound motor runs more smoothly than the high-definition motors available on the market, and there is 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, you only need to change the voltage.

Therefore, there is no need to write control software for this motor, and there is no need to design a circuit board in terms of hardware. It can be said that this motor has the simplest structure.

The motor runs smoothly without vibration, which are necessary conditions for achieving high-precision machine tools.

As time went by, after the motor was made, he also made other parts used on the lathe one by one.

Gearboxes, guide rails, spindles, air bearings, screws, etc., all parts are completed in one step, making them with the highest precision that he can achieve now.

After he made these things, he put them into boxes filled with cushioning materials and kept them for later use.

After all the parts are manufactured, the lathe can also be transferred. The parts he has manufactured now all reach the level of 0.05 microns.

It is not known what kind of processing accuracy can be achieved after these parts undergo strict assembly processes.

Assembly has begun. In the newly built dust-free workshop, the lathe base that has been renovated has been moved into the workshop.

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

After his unremitting efforts, he finally built a complete lathe 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 when he heard the sound coming from the motor, he knew that it was a success.

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

The entire motor was independently designed, manufactured, and assembled by him, and the precision was controlled at the micron level, so the sound of the rotation was so weak.

He put his hand on the motor and felt the faint vibration from the motor, which was all what he expected.

This lathe took him two months, and the energy he spent was indeed not wasted.

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

With the success of the first machine, the rest of the machine tools were also faster. The first day took two months, but the others did not take so long.

Because with this lathe, the industrial workers he received would also have a use for it. He handed over the rough drawings to these workers.

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

With united efforts, all high-precision machine tool parts with single functions were manufactured by them.

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

There are four units in total, two vertical units and two horizontal units. These four machining centers are domestically produced, and their machining accuracy is not very high, and certainly not low, but relatively speaking, they cannot reach high-precision levels.

He added another task later, which was to modify these four machining centers to improve their processing accuracy to a higher level.

The parts that needed to be replaced were manufactured at this time.

While he was making these equipment, the Xiangshan County Air Show was approaching.

His manufacturing trip ended here, and the remaining equipment could only be continued after he returned from Xiangshan County.

Fortunately, at this time, no one from the equipment development department came to place an order for the aircraft, otherwise they would have to break it in two and use it.

I assigned some tasks to these industrial workers and handed 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 operating cockpit and two empty shell models of the aircraft.

The three of them did not go with the things, but took a plane to Xiangshan County, while the aircraft model and control cockpit were transported by land.

The three of them came to the Xiangshan County Air Show Company, the organizer of the air show, 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 and began to contact the decoration company here and began to decorate his exhibition area.

With Guo Shugui here, he doesn't need to worry about these trivial matters. 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. The old man Yan Hang was leading the team this time.

Their arrival also gave him acquaintances and places to visit at the air show, and the exhibition areas of the two companies were very close to each other.

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

One of the real aircraft is the Everlasting Strong Five, the other is the export-type high-attack advanced trainer Falcon, and the model is the Sword UAV, a stealth unmanned attack aircraft that is still in the confidentiality stage.

The exhibition area was decorated by a commercial display company and looked very aesthetic. Just when it was almost decorated, the things they shipped from home finally arrived.

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

The cockpit was also powered on, and people from the Hongdu Factory pushed the Suzaku 3 and Suzaku 8 stored there onto the runway.

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

The two planes, also under his control, took off from the Hongdu Test Flight Ground and flew towards Xiangshan County, Guangdong Province.

The distance between the two places is just within the flight range of the plane, which is just enough fuel for landing.

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

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

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

There is no aircraft the size of a hatchback, and the shape is still so unique that it is difficult not to attract attention.

The Flying Shark pilot who had just landed had just climbed out of the plane and was standing on the runway stretching his body.

From time to time, my eyes are still paying attention to the planes that are about to land on the runway, wanting to see what novel models will appear this time.

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

"Huh? I never heard that this little thing also wants to participate in the exhibition!

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