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

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

For example, many spare parts on the missile, and many link screw holes on it, all require centripetal holes to be punched on the arc with taper, which requires the machine tool to be able to carry out at least one axis linkage. Although the processing of these holes, the most suitable is the five-axis machining center, China has no way to get the five-axis machining center, the only way, can only use tooling to ensure the realization of a shaft that is not very demanding on the schedule, so as to realize the five-axis function on the four-axis linkage machine tool.

With the emergence of simple four-axis modification in China, foreign machine tool manufacturing achievements understand that they can no longer stop the pace of Chinese research on four-axis machining centers. In order to block China's technological progress, a large number of exports to the Chinese market began on the high-end four-axis machining center. As long as there is demand in the Chinese market, they will export without limiting the quantity.

Although the four axes are exported to China, if China wants to get the five axes, it is something that cannot be thought about.

And the threshold of four to five axes is not so easy to enter.

Four-axis CNC machine tools can also achieve a simple fourth-axis function by adding a PMC-module-driven rotary table on top of the three-axis machining center, but it is simply impossible to obtain a simple five-axis in this way.

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

The high price of the four-axis machining center came after the emergence of the simple four-axis modified rotary table in China. There was a significant reduction. At the beginning, the four-axis machining center imported by the military from West Germany can now be completed with only about 1.5 million US dollars.

This price, compared with the initial two million, although a quarter lower, but this price is still not ordinary private enterprises with insufficient strength can accept.

The imported CNC machining center with four-axis linkage is not the kind of four-axis three-linkage machine tool that can be compared with the domestic four-axis three-linkage machine tool with a hydraulic rotary table to realize the simple four-axis function. Many high-precision parts that require four-axis and four-linkage machining centers, such as some parts of aircraft wind tunnel testing, and heat dissipation shells of aircraft engines, are not simple four-axis can be completed.

Even if it's barely finished. The effect of processing cannot meet the requirements of the design.

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

"Xiaoyun, are you dissatisfied with this assignment?" As soon as the meeting was dismissed, Wang Qingfeng asked Yun Fei.

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 in the domestic private market when there are no four-axis machining centers. Yun Fei said solemnly to Wang Qingfeng. Now there are no outsiders, 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 20 percent of the shares that Wang Qingfeng gave him.

Whatever debt you owe, don't owe a debt of favors.

"Doesn't our company have four four-axis machining centers? Still buying? Wang Qingfeng thought that Yun Fei was going to say something important, but in the end he found that Yun Fei was talking about adding a four-axis machining center.

Huadu Xin Kaixing Company was when Sun Lin and Situ Heyun made a hydraulic workstation and a rotary workbench. An order was placed for four modifications. The company's current four four-axis units were personally supervised by Sun Lin and Situ Heyun at the beginning.

Just to renovate these four machining centers, it cost a full 1.2 million! This is still for the other party's sake, Yunfei is also a shareholder of Xinkaixing. The friendly price given!

None of these four-axis machining centers have enough business to keep them running 24 hours a day, six days a year. In many cases, the installed fourth axis is dismantled and used as a three-axis machining center.

"Let's call that four axes?" Yun Fei pursed his lips and despised Wang Qingfeng.

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

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

Nima, with this goods, it's too bad to lose your identity.

As the CEO of a factory focusing on CNC machining, he didn't even understand the real four-axis machining center.

"......" Wang Qingfeng was speechless.

He really hasn't seen a four-axis machining center abroad.

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

The total number of imported four-axis in China will not exceed 20 units, and all of them have entered the research unit except for a small number of them, and most of them have entered the secret unit.

The main ones are the aircraft manufacturing industry in the aviation field and the rocket and missile manufacturing industry in the aerospace field.

For example, some core components such as tanks and warships, although the processing of four-axis machining centers can better ensure the geometric dimensions of space and some shape and position tolerances, but it is far less urgent than the aircraft industry and the rocket and missile industry for high-end machine tools.

Wang Qingfeng has never seen a real four-axis machining center like the EP6, and it is understandable.

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

Yun Fei did not clearly tell Wang Qingfeng that more than half of the foreign trade orders they are doing in the company are military, and most of them are from the navy.

Now Xin Kaixing has established a cooperative relationship with the navy's military factory, and Wang Qingfeng does not know about this.

Many of the military's processed products are transferred through Ren Zhiguo of Kamat, so many times, Kamat has someone in the production workshop of Xinkaixing to supervise the production of Xinkaixing. It is most obvious that the inspection is becoming more and more stringent when the product is handed over to Kamat at the end of the day. Even if it is a little worse, it will not be counted as a substandard product, but will be directly thrown into the waste bin.

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

Since the establishment of Jiuyi Heavy Industry, Yun Fei has rarely dealt with Xinkaixing's technical affairs. The last time I came here, in the workshop, I saw that the tolerances marked on those English drawings and German drawings were too small, and they were very different from the general English drawings.

Yun Fei's original factory is a state-owned enterprise that makes military products.

Although there is not much difference between military products and civilian products in many cases, there is still a big difference between the standards used and those used for civilian products.

The domestic production of military products uses the national military standard, which starts with GJB, while civilian products are all GB, but in these standards, if there is no obvious identification, people who are not very familiar with the two standards cannot be found from the subtle differences.

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 for materials. In the military's own factory, if you want to substitute materials, you have to go through a lot of procedures.

Each product is followed by a quality tracking card, each batch has a material identification report, and the furnace batch number is something that is not used at all on ordinary civilian products.

"How much does it cost?" Wang Qingfeng said knowingly, Yun Fei solemnly proposed it, and the price would definitely not be cheap.

In just three years after Yun Fei entered the company, the company has grown from a small factory with an annual income of 200,000 yuan to a scale with an annual profit of more than 20 million.

"Now it's estimated that I can get seven or eight million!" Yun Fei said lightly.

"Grab the money, this is!" Wang Qingfeng was so shocked by the number that Yun Fei said that he was able to stuff a goose egg in his mouth.

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

"It's pretty cheap. The five-axis machining center, one is about the same size as our 1280 bed, and the price is more than 25 million, which is still priceless. Foreigners don't sell it at all! Yun Fei was very disappointed.

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

"What are we buying it for? There's no product that needs that kind of functionality right now! Wang Qingfeng was really reluctant.

Seven or eight million units, even if you charge 500 yuan an hour, 24 hours a day, it is only 12,000, such a machining center, it takes more than two years to recover the cost of the machine tool!

"As soon as you have the equipment, there will be a large number of orders right away!" Yun Fei said mysteriously to Wang Qingfeng. (To be continued......)
