Smart Industrial Empire

"What's more, five-axis is the most competitive market in the world..." Yun Fei mainly focused on the high-end CNC market.

For a long time, China has been a big importer of these top-level equipment manufacturing industries. Basically, there is no export. Those three-axis machining centers that are exported are also because of their low price and poor performance. A large part of the exports are Taiwan CNC. What the machine tool factory exports, the domestic export is not much.

There is not much profit in the export of low-end CNC machine tools, and the competition is extremely fierce.

High-end CNC machine tools are the most profitable.Jiuyi Research Institute is currently producing a five-axis machining center for testing, and the cost is about 300 million. If mass production is carried out, it can be controlled within 220 million.The lowest price in the market is 500 million, which is about 200 million US dollars.

Besides, it was just a woodworking machine.That is, a light-duty five-axis CNC machining center, and Jiuyi Research Institute has laid out a heavy-duty five-axis machining center from the beginning.

These prices are based on different models have different prices.Larger and more precise ones cost tens of millions of dollars.When China just joined the World Trade Organization in 132, in order to develop the J-0.18 aircraft and mass-produce the J-0.04, Rongcheng 0.05 Factory imported a five-axis five-linkage from the United States, with an x-axis travel of ten meters and a y-axis travel of two Misi's heavy-duty CNC machining center has a straightness of 4000 within the processing range, a repeat positioning accuracy of [-]mm, and a machining accuracy of [-]mm. The price is US$[-] million!This is the most expensive CNC machining center purchased in China.

According to guesswork by professionals, the production cost of this device will never exceed $600 million.

That's the price of technology.

As soon as China's five-axis machining center goes on the market, all five-axis machining centers in the world will have to cut prices.This is a very normal thing.However, the five-axis machining center produced by Jiuyi Heavy Industry will not be announced until Hannover, Germany.

What they have to do is to catch the top powers of CNC machine tools such as the United States, Japan and Germany by surprise.

"Let's go to the finishing production workshop to see how those five-axis machining centers are used." Some of the equipment researched by the September 132st Research Institute was dragged to their production workshop by the [-]nd factory, and some of the equipment with better precision was in the September [-]st Research Institute. A production test workshop affiliated to a research institute.

This workshop not only manufactures various experimental products of the research institute, but also undertakes difficult processing business outside.

This workshop is the place with the highest processing capability in the entire Jiuyi Group.Perhaps, it is also the first-class machining workshop in China. Many of the high-precision and complex parts of the test prototypes of Factory 132 are processed in this workshop, and some super responsible parts of Aerospace next door also find the test workshop of Jiuyi Research Institute.Except for young apprentices, any type of work here is the best skilled and most experienced in the entire Jiuyi Research Institute.Moreover, in order to ensure that the technical level of the workers here is the top of the entire group company, every year the company will hold a technical competition for various types of work, just in June every year.

Skilled workers of different levels, the employees in the production experiment workshop under the research institute are the champions.Accept the challenge of the first-line production technicians in the workshop.

This also means that the skilled workers of the entire group company have a promotion path.

Xinkaixing's technicians will also participate in the competition. Every year, this competition is the most lively, even higher than the national skill competitions.The top skilled workers in China were all recruited by Yunfei.And they pay more attention to the training of skilled workers than any other company.

Technical workers will never be promoted to management because of their good skills, except for those top skilled workers who are about to retire. They are usually responsible for patrolling the production workshop and providing technical guidance.

The skilled workers here are paid higher salaries than the managers.This is the truth.

"Boss, why do you have time to come here today?" As the director of the machining and finishing workshop of Jiuyi Heavy Industry, Fang Qiang was in charge of the two finishing workshops of Jiuyi Heavy Industry because of his outstanding personal ability.Also in charge of the production test workshop of the research institute.

During this period of time, because the entire research institute was working on the public relations five-axis linkage and the automatic automobile production line and supporting robots, he, the workshop director in charge of several workshops, put his main energy into the production and test workshop of the research institute.

It is to ensure that the parts needed by those researchers are processed in the first time.

Cost or something is not considered at all.

The entire production workshop is guarded by duty personnel 24 hours a day.

"Come over and see the production status of those five axes. How is it? There is no big problem, right? A lot of words." Yun Fei nodded to Fang Qiang.

During this period of time because of the attack.These technicians and managers all have dark circles under their eyes, and they all look like they don't have enough sleep.After all, this project is too important, and it was done before the old man came to visit.Everyone knows how much benefit the old man can bring if he is satisfied after reading it.

What's more, Boss Yunda personally gave the order.

"Except for the fact that the processing quality was very unstable in the past period, the quality is still relatively stable after the break-in period. The only problem is that the tool wears out too quickly..." Fang Qiang accompanied Yun Fei, Sun Lin and others They walked towards the gantry-style five-axis machining center with three-meter guide rails on the far side, and talked to Yunfei about the problems they encountered.

"Knife consumption? Is it worn too fast?" Yun Fei asked suspiciously.

The investment of Jiuyi Materials in cutting tools is not small.In particular, the research on nano-scale cubic boron nitride has started many years ago, far ahead of many cutting tool factories in China.

"The main reason is that the processing time is too long, our knives can't bear it, and the effect of imported coated knives is not too ideal..." Fang Qiang explained to Yun Fei.

He knew that Yun Fei knew these things better than he did.Because Yunfei is a professional in mechanical processing.

"In other words, the knives are not wear-resistant enough and don't last long, right? A lot of words." Yun Fei grasped the key point directly, "What is the coating thickness of our knives?"

In mechanical processing, production technology and process equipment (including equipment, fixtures, tools, etc.) are very important.The most important thing is equipment and tools. The parameters contained in the processing program are also very important. For the processing of complex products, these data are kept confidential by many top manufacturing companies.

Those who sell machine tools must test out these data, and then give customers a parameter range, so that customers can give full play to the best performance of the equipment, otherwise, who will buy your equipment next time?

"Two to three wires are already thickened. There is no problem with dry aluminum alloys, but difficult-to-machine materials such as titanium alloys, high-temperature alloys, and stainless steel are not good at all. I have tried various experiments on cutting parameters..." Fang Qiang frowned. said.

"In this way, it is not clear at all whether the cause of the unstable quality is the cause of the tool or the defect of the machine tool itself? Have you done statistics on the status of the tool?" Yun Fei nodded and asked.

Coated tools, different materials require different materials, some use tungsten carbide, some use cubic boron nitride, and some use other superhard coatings, all of which are to increase the service life of the tool, so that Improve the efficiency of CNC machining.

From the very beginning, Jiuyi Material Factory has been researching nano-scale coating material technology from a strategic height, and it was only in [-] that it began to make breakthrough progress.Until now, these technologies have not yet fully stabilized.

The main profit source of Jiuyi Materials lies in the ordinary high-speed tool steel cutting tools and cemented carbide business. Coated cutting tools and advanced material cutting tools such as cubic boron nitride, artificial diamond cutting tools, ceramic cutting tools, etc. have not achieved much in the market. big achievement.

"The zoning data statistics of tool life have been done all the time. After all, the degree of wear is very slight, especially when processing easy-to-machine materials such as aluminum alloy, the tool will basically not have too much wear, but the processing quality still has two Three silk fluctuations..." Fang Qiang shook his head and said to Yun Fei.

"Aviation aluminum is also relatively hard. Is it possible that the knife is worn? Use the side edge or the bottom edge of the knife?" Yun Fei asked with a frown.

If the tool is not worn and the processing quality fluctuates in such a range, it means that the accuracy of the machine tool itself is only two to three wires.For general products, this accuracy is indeed sufficient.But for cutting-edge manufacturing industries such as the aviation industry and the aerospace industry, this is only the level of semi-finishing.

"Both the bottom edge and the side edge have been tested..." Fang Qiang naturally knew what Yun Fei meant, and they also hoped that it was a problem with the tool, not the accuracy of the machine tool itself.In this way, they don't have to work overtime day and night.

Hope is beautiful, but reality is skinny.

Yun Fei took a deep breath, always feeling that something went wrong.

"These equipments are all modified from the first batch of prototypes. The spindles are all new ones before tackling key problems. The control system and control methods have also been changed, because more and more detailed processing data must be obtained. So the CNC system has not been further upgraded..." Sun Lin's words let Yun Fei breathe a sigh of relief.

If it is this precision, this thing really cannot be used to participate in the German machine tool exhibition this year.

"The latest equipment hasn't been assembled yet?" Yun Fei turned to Sun Lin and asked.

"Here, that is the one. It is currently being debugged. We are only starting to do various parameter settings and track running together. The machining accuracy of that one should be controlled to within [-]..." Sun Lin pointed to the front Said the unpainted gantry machining center in the distance.
