Jiang Feng/Wei Wuwei Liu/mechanical experts quickly got the sample spindle and used [metal jet blowtorch] to strengthen the penetration of alloy powder to meet the specified requirements.

The solid steel pipe used for the spindle is confirmed by a 3D+ inspection camera that there are no dark scratches/defects/internal cracks, and the strength and toughness are barely acceptable, but slightly insufficient.

And it lacks anti-rust/anti-corrosion/abrasion resistance!

Therefore, a small electric furnace is used to heat tungsten, titanium, nickel, chromium, copper, aluminum, and molybdenum powder, smelt a homogeneous alloy, and penetrate the steel pipe with a metal jet blowtorch to endow it with high-quality properties.

Corrosion resistance/no rusting/high hardness/high toughness/not easy to deform, the thermal expansion coefficient is very small, and the comprehensive performance is more than 180% stronger than that of ordinary shaft steel pipes!

There is no doubt that for luxury yachts, the performance is more than enough, and warships below 5000t can use this spindle material, and the diameter is thickened.

In the case of a diameter of 15cm, 8000 horsepower constant power propulsion, deformation is less than a trace, does not affect the performance and life of the spindle, anti-collision/bending.

Of course, a luxury yacht, the normal horsepower can never exceed 2000!800--1500 is a relatively reasonable power, and the speed is already very fast!

The yachts at the Yangtze River Shipyard are not big---

Length 19 m / Width 4 m / Displacement 62 tons

The price is expected to be between 8 million and 11 million

The profit margin is not high, 50% of the sky, far less than the profit of accessories;

Shenyang Machine Tool Co., Ltd. is one of the world's top five machine tool manufacturers, with a profit of about 3.85 percent.

Just like Jiang Feng, an industrial enterprise with alien black technology can create 1000% profits, and the cost of this guy is only machine rent, water and electricity, and no salary!

The mercenaries are industrious and tireless ...

Moreover, he is very loyal and obedient, and will not betray or cause any trouble, Jiang Feng is very satisfied! (He didn't know that the police flower Li Qian was drugged and stunned by Qin Da)

To get back to the point, in just half an hour, they contacted Manager Gao again after the spindle and propeller: cutting - alloy penetration - electromagnetic strengthening were completed.

I took 15 pictures/50 seconds of video, all of which were the results of the testing experiment, and I was absolutely qualified! The accuracy and performance far exceeded the requirements, several grades higher.

After the penetration and strengthening of the alloy, the color of the material is black and gray with gloss, which looks extraordinary, and the data is impeccable, which has a slight impact on the accuracy.

Propeller error 0.0015 wire

The spindle diameter error is 0.0009 wires

The curvature error of the spindle is 0.0015 wires

The hole size error is 0.0008 wires

Supports 8000 horsepower of rotational power

..... Wait a minute.....

There are test results in the photos, and the mercenaries' own testing equipment shows the numbers, which are clearly displayed, and each data is guaranteed to be true and valid, which makes it impossible to question.

[Yangtze River Shipyard] purchasing manager - Gao Yunbo has reported the situation to the company's general manager/technical director/technical consultant and other senior leaders and asked how to arrange it.

The sudden appearance of [Lingfeng Technology Company] showed mysterious and strong strength, which attracted the attention of the senior management of [Yangtze River Shipyard], and they quickly rushed over for a meeting.

General Manager/Deputy General Manager/Consultant/Director/There is also Gao Yunbo, the purchasing manager, who works overtime to study and discuss, consider the issue of this order, and the issue of cooperation.

As soon as they arrived at the conference room, they received photos and videos from Jiang Feng, and everyone talked about it---

General Manager: "Consultant Zhao, Director Li, do you see that these photos are real, or are they faked by the other party?"

"It should be true, not like forgery, not to mention that there is no need for the other party to forge it! With all due respect, this machine tool is probably obtained from Germany. Advisor Zhao replied.

The technical director also agreed: "That's right, I haven't seen this kind of machine tool in China, three tools work at the same time, it is definitely not a five-axis machining center, and the seven-axis one is not like it..."

They looked down one picture at a time, the more they looked at it, the more surprised they felt, and finally they were completely stunned, the processing accuracy actually reached 0.0008 silk!

"I'm dying~ This is a nine-axis industrial machine?"

"It should be... Nine-axis five-linkage machine tool!"

"That's right! Only [Nine-axis Industrial Machine] can achieve this level of accuracy, 100 nanometer error, how can this special appear in the people, how is it possible?"

"Do you need to talk about this? smugglers~"

According to the provisions of the [Batumi Treaty], machining centers with more than five axes and five linkages are prohibited from being exported to socialist countries such as China and Russia for a very simple reason---

Without the nine-axis industrial machine tool, it is impossible to create high-precision aviation/aerospace/nuclear/military/steam turbine blades and other cutting-edge products, hindering the development of science and technology.

Although it is very helpless, I have to admit that this plan has been very successful, setting up obstacles for China and slowing down the development of industrial science and technology for more than ten years!

At present, domestic seven-axis six-linkage and even nine-axis linkage industrial machine tools have been put into use, which are limited to large military enterprises/state-owned enterprises/pilot enterprises.

Because the technology is not yet mature!

An imported nine-axis industrial machine is of great value to the whole country, and do you remember the Soviet Union? A large number of industrial machine tools were smuggled from the island countries, and submarine technology soared.

Therefore, the leaders of [Yangtze River Shipyard] showed extreme surprise and shock at Lingfeng Technology's mastery of the nine-axis industrial machine tool, and expressed their complete disbelief.

If it's true, it's awesome!

The processing level must be flying up!

What are the industrial manufacturing problems that cannot be solved by a nine-axis linkage machine tool? If there is, then you may need two! It is comparable to a cash cow~

After some research, everyone unanimously agreed to sign a long-term cooperation agreement with Jiang Feng to deepen cooperation, and not to disclose the news about the nine-axis industrial machine tool, to keep it secret!

Make a fortune in silence and avoid official attention.

Soon, Jiang Feng received a reply, and the general manager of the shipyard called in person to determine the content of the agreement, hoping to come to negotiate tomorrow for in-depth cooperation.

Although the Yangtze River Shipyard is not a large group, it is very famous in the province--- the largest inland shipyard, and the annual output of yachts, cargo ships and passenger ships is hundreds!

The propellers/gearboxes/spindles and even diesel engine units of these ships are all potential businesses, and it is impossible for Jiang Feng to refuse the other party and take the initiative to offer an invitation.

Brief communication, make an appointment tomorrow at noon, go directly to the maintenance factory to meet, ask for a truck, start production tonight part of the order, tomorrow by the way.

General Manager: "......" [speechless]

Director Li: "......" [confused]

Consultant Zhao: "......" [kneeling]

Although it is a business of 20 million, in fact, it is about two or three days of work, which is easy, Jiang Feng is not willing to waste too much time, and the money is only solid when he has it!
