Chapter 303

With the development of China's manufacturing industry and manufacturing technology, more and more products need to be processed by four-axis machining centers in China.

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

For example, many spare parts and connecting screw holes on the missile require centripetal holes on the circular arc with taper, which requires that the machine tool must be able to carry out at least one axis linkage. Although the most suitable machining center for these holes is the five axis machining center, China simply has no way to obtain the five axis machining center. The only way is to use tooling to ensure the realization of an axis that does not require high progress, so as to realize the five axis function on the four axis linkage machine tool.

With the emergence of simple four-axis refitted in China, foreign machine tool manufacturing achievements understand that they can no longer stop the Chinese from studying four-axis machining centers. In order to block China's technological progress, we began to export large quantities to the Chinese market on the high-end four-axis machining center. As long as there is demand in the Chinese market, they will export without limit.

Although the four axes are exported to China, if China wants to get the five axes, it's something we don't even want to think about.

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

The four-axis NC machine tool can also realize the simple fourth axis function by adding a PMC module driven rotary worktable on the three-axis machining center, but it is impossible to obtain the simple five axes in this way.

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

The high price of four-axis machining center has been greatly reduced after the emergence of simple four-axis refitted domestic rotary worktable. The four axis machining center imported by the military from West Germany only needs about US $1.5 million to complete.

Although this price is a quarter lower than the initial two million, it is still not acceptable to ordinary private enterprises with insufficient strength.

The imported CNC machining center with four-axis linkage is not comparable to the four-axis three-axis linkage machine tool equipped with a hydraulic rotary worktable to realize simple four-axis function in China. Many high-precision parts that require four axis and four linkage machining centers to complete, such as some parts of aircraft wind tunnel test, heat dissipation shell of aircraft engine, etc., can not be completed by simple four axis.

Even if it can be barely completed, the processed effect can not meet the design requirements.

Yun Fei originally wanted to suggest Xin Kaixing to use the profits accumulated in the past two years to purchase the four-axis machining center, but Wang Qingfeng asked for money at the beginning, and he couldn't stop it. Wang Qingfeng is the boss of the factory.

"Xiao Yun, are you not satisfied with this assignment?" Just after the meeting, Wang Qingfeng asked Yunfei.

At the meeting, he said that after dividing the company's profits, he obviously saw Yun Fei's mouth move.

"Lao Wang, we should now add at least two four-axis machining centers when there are no four-axis machining centers in the domestic private market." Yun Fei said solemnly to Wang Qingfeng. Now there is no outsider. The purchase of the four-axis machining center is related to the future development of Huadu xinkaixing. If he doesn't say, he will be sorry for the 20% shares given to him by Wang Qingfeng.

Don't owe any debt to others.

"Doesn't our company have four four axis machining centers? Still buy? " Wang Qingfeng thought Yunfei was going to say something important. In the end, he found that Yunfei said about adding a four-axis machining center.

Huadu xinkaixing company placed an order for four refitted hydraulic workstations and rotary worktables when Sun Lin and situ Heyun came up with them. Sun Lin and situ Heyun personally supervised the refitting of the company's four sets and four axes.

Only the transformation of these four processing centers cost a full 1.2 million! This is the friendship price given by the other party for the sake of Yunfei, who is also the shareholder of xinkaixing!

These four-axis machining centers don't have enough business to keep them running 24 hours a day. Many times, the added fourth shaft is removed and used as a three-axis machining center.

"We call that four axis?" Yun Fei skimmed his lips and despised Wang Qingfeng.

"This is not a four axis. What is it? Don't our four-axis machining center have a fourth axis with rotation? " Although Wang Qingfeng is the boss of the top three machining companies in the industry in Huadu, he still doesn't really understand CNC machine tools.

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

Nima, it's disgraceful to be with this goods.

As the boss of a factory mainly engaged in NC 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.

"What else can our four axis machining center do besides making some small shaft parts and box parts? Can those large box parts, or larger disc parts and heavier shaft parts be processed? " Yunfei'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.

At present, the total number of imported four axes in China will not exceed 20. Except a small number of them have entered the research unit, most of them have entered the confidential unit.

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

For example, some core parts such as tanks and warships, although processing with four-axis machining center can better ensure spatial geometric dimensions and some geometric tolerances, they are far less urgent than the aircraft industry and rocket missile industry for high-end machine tools.

It is understandable that Wang Qingfeng has never seen a real four-axis machining center such as ep6.

"We xinkaixing are mainly engaged in NC machine tool processing business. Many important customers have a lot of business in demand for high-precision machine tools. These customers are the ones we should focus on. As long as we can eat the four-axis processing business in their hands, will they not give us the three-axis business? "

Yunfei didn't clearly tell Wang Qingfeng that more than half of the foreign trade orders they made in the company were from the military, most of which were from the Navy.

Now xinkaixing has established a cooperative relationship with the Navy's military factory, which Wang Qingfeng doesn't know.

Many military processed products are transferred through Ren Zhiguo of camart. Therefore, many times, someone in camart supervises the production of xinkaixing in the production workshop of xinkaixing. It is most obvious that the inspection is becoming more and more strict when the products are finally handed over to camart. Even a little out of tolerance will not be regarded as unqualified products, but will be directly thrown into the waste box.

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

Since the establishment of Jiuyi heavy industry, Yunfei has rarely dealt with xinkaixing technology. Last time I came here, I saw that the tolerance marked on the English drawings and German drawings in the workshop was too small, which was very different from the general English drawings. After synthesizing the drawings from several companies, Yun Fei found that the inside was fishy.

Yunfei's original factory is a state-owned enterprise engaged in military products.

Although there is not much difference between military products and civil products, there are still great differences between the standards adopted by military products and civil products.

Domestic military products use the national military standard, starting with g * *, while civil products use GB. However, if there is no obvious mark in these standards, people who are not very familiar with the two standards can't find the subtle differences at all.

The most significant difference between the national military standard and the national standard is that even the most common materials are absolutely not allowed to substitute materials. In the military's own factories, if you want to substitute materials, there must be a lot of formalities.

Each product is accompanied by a quality tracking card, and each batch has a material identification report, furnace batch number, which are basically useless for ordinary civil products.

"How much is it?" Wang Qingfeng knew that the price would never be cheap if Yunfei put it forward so solemnly.

Just three years after Yunfei entered the company, the company has developed from a small factory with an annual income of 200000 to 300000 to a scale with an annual profit of more than 20 million, which makes Wang Qingfeng take Yunfei's opinions as the golden rule.

"Now it's estimated that you'll get seven or eight million!" Yun Fei said faintly.

"Rob money, this is!" Wang Qingfeng was so surprised by the numbers Yun Fei said that he could put a goose egg in his mouth.

Seven or eight million, it's just the price of one!

"It's cheap. The five axis machining center is about the size of our 1280 bed, with a price of more than 25 million. It is still a price without market. Foreigners don't sell at all! " Yun Fei is very lost.

If we can sell the five axis machining center now, xinkaixing will be invincible for at least ten years.

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

Seven or eight hundred and one thousand units, even if you charge 500 yuan an hour, 24 hours a day, it is only 12000. Such a processing center needs more than two years to recover the cost of the machine tool!

"As long as there is equipment, there will be a large number of orders immediately!" The cloud said to Wang Qingfeng mysteriously.
