Chapter 897 Really Difficult Technical Breakthrough (2)

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

You know, the theoretical accuracy of their three-axis machining centers have reached the international first-class level of 0.005mm, and the top-level ones can fully guarantee the machining accuracy within 0.01.

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

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

They have also tried their best.

"Furthermore, the electric spindle we use for this spindle has a maximum speed of 12,000 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 trouble is the tool. Guo Chuan from the material factory has been improving the coating materials, and I don’t know when it will be successful..."

"This is the basis of the entire domestic material. If it doesn't work, let's get the best knives from abroad to test. People who are more advanced than us can't ignore it..." Yun Fei shook his head and said.

The entire group company may be affected by Yunfei. Except for top foreign instruments and equipment, it rarely purchases foreign equipment.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 great waste of research funds.

But Yun Fei didn't care about such things.

The money, no matter how much it is, it's just a bunch of data. God wants him to come into this world once, and he definitely wants him to keep something.Even if Bill had so much money, in the end he died, wouldn't it be impossible to take the money with him?

The greatest pain in life is nothing more than death, leaving behind countless money that will not be spent in a lifetime.

What about richer?It's better to do something, there will always be people who will remember themselves.

Habit is a terrible thing.The entire Jiuyi Research Institute is now so sick that it doesn't use all foreign things.This group of guys counts on making everything by themselves. They don't need to pay for it anyway. Boss Yun has money, but the sense of honor for this achievement belongs to them.

Even if Yun Fei is uncomfortable with this matter, he has no way to stop it, fearing to dispel the research enthusiasm of these technical researchers.

"How long will the five-axis debugging be completed?" Yunfei saw the already formed equipment, the debugging program was running, and the machine tool was running back and forth at a fast moving speed, just to run in the guide rail...

"It takes more than three days to run uninterrupted for 24 hours. This five-axis rapid displacement speed is 18 meters per minute. This speed is a bit slow..." Sun Lin pointed to several white coats in front of him. The staff of the five-axis machining center with some data written on the notepad in hand introduced various related parameters to Yunfei.

"The three axes of XYZ shouldn't be a big problem, right? Look at the swing range of the A-axis and C-axis..." Yunfei nodded.

Fast running-in is something that any CNC machine tool must do before leaving the factory. This process is the necessary action to eliminate the assembly gap and find the gap caused by the error in the assembly.

Regardless of any equipment, the running-in of the three most basic moving directions of XYZ is the most critical.

Jiuyi Heavy Industry started producing gantry machining centers several years ago. The basic technology and principles are the same. Therefore, what he most wants to see is the C-axis based on Z-axis swing rotation.

The direction of rotation of this shaft is ±220°, which adopts international standards.

The five axis, the most critical, is actually the fifth axis of rotation.After all, the basis of the four-axis is there.

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

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

Sun Lin whispered to a thin middle-aged man who was always watching the operating parameters of the machine tool. The operation of the machine tool stopped after a few clicks on the test console in front of the computer.

When the person in charge of the debugging turned his head and took a look, it was suddenly Luo Feng, who looked exactly like his master Zhao Jinshan, who made Yun Fei a technician who bought it from the 132 factory with a million.

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

Not a professional computer software engineer, but he can expand the domestic CAXA 3D drawing programming software according to his own ideas, and he can also design more powerful plug-ins; more importantly, he is one of the earliest technicians of processing centers in China. I have a good understanding of the various parameters and performance of these devices.

After this guy was bought by Yunfei, the 132 factory realized his importance. It was impossible to buy it back.

"We don't know what the performance of the five-axis abroad is, but the equipment we built has big defects for the processing of some key parts of the aircraft, mainly because the machining accuracy is not enough. Especially the cumulative error is a bit large..." Said to Yun Fei calmly.

The boss is easy-going and rarely treats researchers coldly.

"The problem of the assembly gap?" Yun Fei frowned immediately, "Isn't there any response to these problems to Elder Sun?"

Is there a problem with the close connection on the academy side?

"Many problems can only be discovered after running for a period of time. Five axes, we don't have much experience, these things can only find a little and solve a little..." Luo Feng meant, how can Yun Fei not know?

This is also no alternative.

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

Under Luo Feng's control, the spindle began to swing slowly. Judging from the movement, there was no problem, the only thing was the accuracy during processing.

"These can only be known about the specific problems after the commissioning is completed and the processing test is carried out. These things that are seen in theory are not reliable. Moreover, the spindle connector is not too fast because of the hydraulic method... …" Sun Lin and the others are also a little uncertain about the actual performance of this latest five-axis machining center.

The theoretical aspects are always not easy to reach.

"Then follow the original schedule. I heard that one of our test equipment was pulled away from the impeller factory?" Yun Fei suddenly asked Sun Lin next to him, "What is their feedback?"

"The problem is not big. The impellers produced by them are not very demanding. The data obtained from the three-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."It's not just that they took away one, but the 132 factory also took away two. These equipments have been discussed and decided because of performance problems. Each unit is 16 million, and the 132 factory has settled 20 million. I didn't give a penny..."

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

In the next few days, Yunfei stayed in the research institute to look at various test data. The supercomputers of the data research institute were very thorough.The reason why the various researches of the Jiuyi Research Institute can progress so quickly is because of the constantly upgrading supercomputer named Yunjiuyi.

All kinds of large-scale calculation simulations, modeling and analysis, etc., can quickly get test results.

After the equipment was debugged, Yunfei didn't have the patience to continue watching the test results because the tool wear was too serious.When machining aerospace duralumin, it will not take long for the coating on the outside of the tool to be gone. Just cutting with the alloy matrix inside will make the wear more serious.

Although imported knives can be transported by air freight through Philips soon, the price is too expensive.

A three-tooth coated milling cutter with a diameter of 8mm is only more than 100 yuan in China, and the best foreign ones they buy are actually more than 60 euros!These gadgets are still not exported to China, even Philip, he got them from their warehouse for the Jiuyi Research Institute.

This is simply deadly.

If the domestic cannot provide matching tools, the production cost is too high, it is likely to affect their five-axis sales, and the consumption of domestic ordinary tools is too high.

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

But the train is fast. At this time when the speed has not been increased, it only takes more than four to five hours.

But whether it is a train or driving by yourself, this time is long enough. After the highway is repaired, it will only take two hours to drive from Rongcheng to Guocheng. Yunfei originally used a high-energy-consuming unit like a material factory. And for these reasons, factories such as foundries are located in Guocheng.

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

Industrial electricity is much cheaper than Chengdu, and after the highway is completed, the cost of transportation will be reduced on a large scale.The Jialing River can navigate 3,000-ton cargo ships, and there are also airports. The preferential rate is far greater than that of Chengdu.

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