Smart Industrial Empire

"This is just theoretical data, right? Wasn't the theoretical accuracy of these at the beginning also within 0.02?" Yun Fei sighed.This matter is too far from what he thought.

It should be known that the theoretical precision of their three-axis machining centers has reached the world-class level, and the top-level ones can fully guarantee the machining accuracy within 0.01.

This level of machining center is not inferior to those foreign three-axis machining centers exported to China.Otherwise, the market share of Jiuyi Heavy Industry will not remain so large, and it is even very likely that it will encounter anti-monopoly laws in the future.

"The actual theoretical data is already considered to be high-precision for an ordinary five-axis. But it can't reach the precision level..." Sun Lin sighed.

They have also tried their best.

"Moreover, the electric spindle we use for this spindle has a maximum speed of [-] and a gantry structure. In order to ensure the machining accuracy of the machine tool, the worktable is fixed and the tool moves in all directions. The specific performance must be verified. The only problem is the knife, Guo Chuan at the material factory has been improving the coating material, and I don’t know when it will be successful..."

"In terms of materials, the foundation of the entire country is like this. If it really doesn't work, just get the best knives from abroad and come back for testing. They are more advanced than us, so we can't ignore it..." Yun Fei shook his head and said.It is really difficult to update the 935 technology breakthrough. The entire group company may be affected by Yunfei, except for the top foreign equipment.Rarely purchased abroad.And many top-level instruments are embargoed to China.They are like those technicians in the Taizu era, all relying on self-reliance, which caused a lot of waste of research funds.

But Yunfei didn't care about such things.

This money, no matter how much it is, is just a bunch of data. When God let him come to this world once, he must have wanted him to keep something.Even with as much money as Bill's old man, in the end he died.Can't you take the money with you?

The greatest pain in life is death.There are also countless lifetimes of money left behind.

So what if you have more money?It's better to do something, when the time comes, there will always be someone who will remember me.

Habits are a terrible thing.The entire Jiuyi Research Institute is now so sick that it does not use all foreign things.All these guys are counting on themselves to make it out.Anyway, they don't need to pay. Boss Yunda has plenty of money. The sense of honor of this achievement is their own.

Even though Yun Fei was upset about this matter, he had no way to stop it, for he was afraid of dissuading the research enthusiasm of these technology researchers.It is really difficult to update the 935 technology breakthrough. "How long will it take to complete the debugging of this five-axis machine?" Yunfei saw the equipment that has been formed, the debugging program is running, and the machine tool is running back, forth, left, and right at a fast moving speed, just to break in the guide rails ...

"24 hours of uninterrupted running. It will take more than three days. The rapid displacement speed of this five-axis is 18 meters per minute. This speed is a bit slow..." Sun Lin pointed to several workers in white coats in front of him The five-axis machining center, where the personnel were constantly writing some data on the notepad in their hands, introduced various relevant parameters to Yunfei.

"The three axes of x/y/z shouldn't be a big problem, right? Look at the swing range of the a-axis and the c-axis..." Yun Fei nodded.

Quick run-in This is what any CNC machine tool must do before leaving the factory.This process is a necessary action to eliminate the assembly gap and find the gap caused by the error in assembly.

Regardless of any device, the running-in of the three most basic movement directions of x/y/z is the most critical.

Jiuyi Heavy Industry has started producing gantry-type machining centers a few years ago, and the basic technologies and principles are the same. Therefore, what he most hopes to see is the c-axis based on the swing and rotation of the z-axis.

The direction of rotation of this shaft is ±220°.International standards are adopted.

Five-axis, the most critical.In fact, this is the fifth axis of rotation.After all, the foundation of the four-axis is there.

The initial parameter setting of the machine tool has been completed, and now it is mainly to debug, find out the problem, and improve the assembly accuracy of the equipment. These processes must be done by experienced top assembly workers.

The reason why the performance of these machine tools produced by Jiuyi Heavy Industry is far higher than that of domestic counterparts is because they have the most top assembly technicians in China.

Sun Lin whispered something to a relatively thin middle-aged man who was always monitoring and monitoring the operating parameters of the machine tool. He clicked a few times on the test console in front of the computer, and the machine tool stopped running.

When the person in charge of debugging turned his head to take a look, suddenly it was Luo Feng, the technician who looked exactly like his master Zhao Jinshan, and Yun Fei bought it from Factory 100 for 132 million.

"Master Luo, have you tested the performance of these devices?" Luo Feng fully demonstrated his value in the research institute.

He is not a professional computer software engineer, but he can expand the domestic caxa [-]D graphics programming software according to his own ideas, and can also design more powerful plug-ins; more importantly, he is the first batch of domestic machining center technicians, They are very familiar with the various parameters and performance of these devices.

After this guy was bought by Yun Fei, Factory 132 realized his importance. It was impossible to buy him back.

"We don't know the performance of the foreign five-axis, but the equipment we made has a lot of defects in the processing of some key parts of the aircraft, mainly because the processing accuracy is not enough. Especially the cumulative error is a bit large..." Luo Feng Said to Yun Fei calmly.

The boss is easy-going and rarely gives researchers a cold face.

"A problem with the assembly gap?" Yun Fei frowned immediately, "Aren't these problems answered to Mr. Sun and the others?"

Could it be that there is also a problem with the tight connection on the research institute's side?

"Many problems can only be discovered after running for a period of time. We don't have much experience with the five-axis, and these things can only be found and solved a little bit..." How could Yun Fei not know what Luo Feng meant?

This is also impossible.

"We don't have enough time to develop slowly..." Yun Fei sighed.

Under Luo Feng's control, the main shaft began to swing slowly. Judging from the movement, there was no problem, the only thing was the precision of machining.

"The specific problems can only be known through processing tests after the commissioning is completed. Now these things seen in theory are unreliable. Moreover, the connecting head of the main shaft is not swinging too fast because of the hydraulic method... ..." Regarding the actual performance of this latest five-axis machining center, Sun Lin and the others are also a little uncertain.

Theoretical things are not always easy to achieve.

"Then follow the original schedule. I heard that one of our test equipment impeller factories has been taken away?" Yun Fei suddenly asked Sun Lin next to him, "How about their feedback?"

"It's not a big problem. The precision requirements of the impellers they produce are not very high. The data obtained by the three-dimensional coordinate detection are the same as the test results obtained by us. Otherwise, they would not dare to use such equipment for processing?" Deng Lanqing said with a smile. "Not only did they take away one, but the 132 factory also took away two. Due to performance problems, these devices were discussed and decided to be 600 million each, and the 132 factory settled 2000 million. No money was given to…”

"Money is not important, the key is to get the first-hand data." Yun Fei really didn't expect that Factory 132 was so urgent.

For the next few days, Yun Fei stayed in the research institute to look at various test data, which were analyzed very thoroughly by the supercomputer of the research institute.The reason why the various researches of the Jiuyi Research Institute can progress so quickly is because of the constantly upgraded supercomputer named Yun Jiuyi.

All kinds of large-scale computing simulations, modeling analysis, etc., can quickly obtain test results.

After the equipment debugging was completed, Yunfei didn't have the patience to continue watching the test results here, because the tool wear was too serious.When machining aviation duralumin, it will not take long for the coatings on the outside of the tool to disappear, and the wear will be more serious if it is only cut by the alloy matrix inside.

As for imported knives, although they can be transported by air freight through Philip soon, the price is too expensive.

A three-tooth coated milling cutter with a diameter of 8mm costs only more than 100 yuan in China, but the best ones they bought abroad are more than 60 euros!These things are still not exported to China. Even Philip got them from their warehouse for the Jiuyi Research Institute.

This is simply killing me.

If the country cannot provide matching tools, the production cost will be too high, which may affect their five-axis sales, and the consumption of domestic ordinary tools will be too high.

"If the Rongguo Expressway is completed, it will be fast from Rongcheng to Guocheng..." The expressway from Rongcheng to Guocheng has not been completed yet, and it will take nearly six hours to take the old road.

But the train is fast. Before the speed was increased, it took only four or five hours.

But whether it is by train or by car, this time is long enough. After the highway is repaired, it only takes two hours to drive from Rongcheng to Guocheng. And the layout of factories such as foundries in Guocheng is for these reasons.

Guocheng is close to the Jialing River and has abundant hydropower resources.

Industrial electricity is far cheaper than in Chengdu, and after the expressway is completed, the cost of transportation costs will also be reduced on a large scale.The Jialing River is capable of navigating [-]-ton cargo ships, and it also has an airport. The discount is far greater than that of Rongcheng.

Anyway, in Rongcheng, it is not close to the origin of various raw materials.
