Smart Industrial Empire

With the development of China's manufacturing industry and manufacturing technology, there are more and more products in China that need four-axis machining centers to process.

China's largest demand for four-axis machining centers is not the civilian machinery manufacturing industry, but the military industry.

For example, many spare parts on the missile, and many connecting screw holes on it, all require centering holes on a tapered arc, which requires that the machine tool must be able to carry out at least one axis linkage.Although the machining of these holes is the most suitable five-axis machining center, there is no way to get a five-axis machining center in China. The only way is to use tooling to ensure the realization of an axis that does not require a high schedule. , so as to realize the five-axis function on the four-axis linkage machine tool.

With the emergence of the simple four-axis modified by China, the achievements of foreign machine tool manufacturers are clear, and they can no longer stop the pace of Chinese research on four-axis machining centers.In order to stop China's technological progress, high-end four-axis machining centers have been exported to the Chinese market in large quantities.As long as there is demand in the Chinese market, they will export without limiting the quantity.

Although the four-axis is exported to China, if China wants to get five-axis, it is something that is not even thought about.

Moreover, the threshold from four-axis to five-axis is not so easy to enter.

The four-axis CNC machine tool can also realize the simple fourth-axis function by installing a rotary table driven by the PMC module on the three-axis machining center, but it is simply impossible to obtain a simple five-axis by this method.

On the surface, compared with the four-axis linkage machining center, the five-axis linkage machining center only has one more automatic angle of swing, but it is just an increase in the swing angle. The technical problems and manufacturing technology have been improved by more than ten times. .

The high price of the four-axis machining center, after the appearance of the simple four-axis modified by the domestic rotary table.There has been a substantial reduction.At the beginning, the four-axis machining center imported by the military from West Germany can be completed for only about 150 million US dollars.

Although this price has been reduced by a quarter compared with the original 200 million, this price is still not acceptable to ordinary private companies with insufficient strength.

The imported CNC machining center with four-axis linkage is not comparable to the domestic four-axis three-linkage machine tool that is equipped with a hydraulic rotary table to realize simple four-axis functions.Many high-precision parts that require four-axis and four-linkage machining centers, such as some parts of aircraft wind tunnel tests, heat dissipation housings of aircraft engines, etc., cannot be completed by simple four-axis.

Even barely able to finish.The effect of processing can not meet the design requirements.

Yun Fei originally wanted to suggest that Xin Kaixing use the profits accumulated in the past two years to purchase four-axis machining centers, but Wang Qingfeng proposed to divide the money from the beginning, and he couldn't stop him. Wang Qingfeng is the one The boss of the factory.

"Xiao Yun, are you dissatisfied with this assignment?" Wang Qingfeng asked Yun Fei just after the meeting ended.

At the meeting, after he said that he had divided the company's profits, he clearly saw Yun Fei's mouth move.

"Old Wang. We should now buy at least two four-axis machining centers when there are no four-axis machining centers in the domestic private market." Yun Fei said to Wang Qingfeng seriously.There are no outsiders now, and the purchase of a four-axis machining center is related to the future development of Huadu Xinkaixing.If he didn't say it, he would be sorry for the [-]% of the shares that Wang Qingfeng gave him back then.

Do not owe any debts to favors.

"Didn't our company have four four-axis machining centers? Do you still want to buy them?" Wang Qingfeng thought that Yunfei was going to talk about something important, but in the end he found out that Yunfei was talking about purchasing a four-axis machining center.

When Sun Lin and Situ Heyun developed the hydraulic workstation and rotary table in Huadu Xinkaixing Company.Just placed an order for four modifications.The company's current four four-axis, but Sun Lin and Situ Heyun personally supervised the modification.

It cost a full 120 million just to transform these four machining centers!This is because the other party sees that Yunfei is also a shareholder of Xinkaixing.The friendly price given!

These four-axis machining centers still don't have enough business to keep them running 24 hours a day.In many cases, the installed fourth axis is removed and used as a three-axis machining center.

"We call it Four-axis?" Yun Fei pouted, despising Wang Qingfeng.

"What is this if it's not a four-axis? Don't our four-axis machining centers have a fourth axis with rotation?" Although Wang Qingfeng is the boss of a machining company that has been able to rank among the top three in the industry in the Huadu area, but for CNC machine tools , he still really doesn't understand.

"Old Wang, when you go out in the future, don't tell people that you are the boss of Xinkaixing..." Yun Fei distanced himself from Wang Qingfeng.

Nima, being with this guy is too demeaning.

As the boss of a factory mainly engaged in CNC machining, he didn't even understand the real four-axis machining center.

"..." Wang Qingfeng was speechless.

He has never seen a foreign four-axis machining center.

"Our four-axis machining center, in addition to making some small shaft parts and box parts, what else can it do? Those larger box parts, or larger disc parts, heavier shafts Such parts, can it be processed?" Yun Fei's words instantly made Wang Qingfeng understand the difference between the four-axis machining center used in their factory and the real four-axis machining center.

The current imported four-axis in the country will not exceed twenty units in total. Except for a small number of them, they have entered the research unit, and most of them have entered the confidential unit.

It is mainly the aircraft manufacturing industry in the aviation field, and the rocket and missile manufacturing industry in the aerospace field.

For example, for some core parts such as tanks and warships, although four-axis machining centers can better guarantee the spatial geometry and some shape and position tolerances, it is far from as urgent as the aircraft industry and the rocket and missile industry for high-end machine tools.

It is understandable that Wang Qingfeng has not seen a real four-axis machining center such as ep6.

"Our Xinkaixing is mainly engaged in the CNC machine tool processing business. Many important customers have a lot of business that requires high-precision processing machine tools. These customers are the customers we should focus on developing. As long as they have four-axis machining We can afford the business, but will they not give us the three-axis business?"

Yunfei did not explicitly tell Wang Qingfeng that more than half of the foreign trade orders they are making in the company are from the military, and most of them are from the navy.

Now Xin Kaixing has established a cooperative relationship with the Navy's military factory, which Wang Qingfeng does not know.

Many processed products of the military are transferred through Ren Zhiguo of Kmart. Therefore, in many cases, Kmart has someone in Xinkaixing's production workshop to supervise the production of Xinkaixing.The stricter and stricter inspection is the most obvious when the product is finally handed over to Kmart for inspection.Even if it is a little bit worse, it will not be regarded as a substandard product, but will be thrown directly into the waste bin.

Yun Fei didn't know it at first. In order to avoid being guessed, the military actually converted those blueprints into English blueprints.

After Jiuyi Heavy Industry was established, Yunfei seldom dealt with Xinkaixing's technical matters.When I was here last time, in the workshop, I saw that the tolerances marked on the English drawings and German drawings were too small, which was very different from the general English drawings. It is said that they came from several companies. After drawing the blueprints, Yun Fei found out what was tricky inside.

Yun Fei's original factory was a state-owned enterprise that manufactures military products.

Compared with military products and civilian products, although there is not much difference in many cases, the standards adopted are still very different from those adopted by civilian products.

Domestic military products use the ** standard, which starts with gjb, while civilian products all use gb. However, in these standards, if there is no obvious mark, people who are not very familiar with the two standards will not be able to distinguish from the subtleties. found in the differences.

The most significant difference between the ** standard and the national standard is that even the most common and common materials are absolutely not allowed to substitute materials.In the military's own factories, if you want to substitute materials, you have to go through a lot of procedures.

Every product is followed by a quality tracking card, and each batch has a material identification report, batch number, etc., which are not used in ordinary civilian products.

"How much is one set?" Wang Qingfeng knew that the price would definitely not be cheap when Yunfei proposed it so solemnly.

In just three years after Yunfei joined the company, the company has grown from a small factory with an annual income of 30 million yuan to a scale with an annual profit of more than 2000 million yuan. This has made Wang Qingfeng regard Yunfei's opinion as a golden rule.

"Now it is estimated that it will be seventy-eight million!" Yun Fei said lightly.

"It's stealing money, this is it!" Wang Qingfeng was so shocked by the number Yun Fei said that he could stuff a goose egg into his mouth.

Seventy-eight million yuan is actually only the price of one!

"It's pretty cheap. A five-axis machining center, which is about the size of our 1280 bed, costs more than 500 million yuan. It's still a bargain. Foreigners don't sell it at all!" Yun Fei was very disappointed.

If the five-axis linkage machining center can be sold now, Xinkaixing will be invincible for at least ten years.

"What are we buying it for? There is no product that needs that function now!" Wang Qingfeng was really reluctant.

Seventy-eight million units, even if you charge 800 yuan an hour, 500 hours a day, it is only 24. Such a machining center will take more than two years to recover the cost of the machine tool!

"As soon as we have the equipment, there will be large orders!" Yun Fei said to Wang Qingfeng mysteriously. (To be continued..)
