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

For a long time, China is a big importer of these top equipment manufacturing industries, basically there is no export, the export of those three-axis machining centers, are also because of the low price, the performance is not very good, a large part of the exports are exported by Taiwan CNC machine tool factory, domestic exports are not much.

The export of low-grade CNC machine tools is not very profitable, and the competition is fierce.

The profit of high-end CNC machine tools is the most huge. The Jiuyi Research Institute now produces a five-axis machining center for testing, with a cost of about 3 million, and if mass production is carried out, it can be controlled within 2.2 million. The lowest selling price in the market is 15 million, or about $2 million.

Besides, it's just a carpentry machine. That is, a lightweight five-axis CNC machining center, and Jiuyi Research Institute has laid out a heavy-duty five-axis machining center from the beginning.

These prices vary depending on the model. The larger ones are more accurate and tend to be tens of millions of dollars. In 01 year, when China had just joined the World Trade Organization, Rongcheng 132 Factory imported a five-axis five-linkage, X-axis travel of ten meters, Y-axis travel of two meters and four meters of heavy-duty CNC machining center from the United States in order to develop J-20 aircraft and mass production of J-10, with a straightness of 0.18, repeated positioning accuracy of 0.04mm, machining accuracy of 0.05mm, and a price of 40 million US dollars!

This is the most expensive CNC machining center purchased in China.

According to the speculation of professionals, the production cost of this equipment will definitely not exceed six million dollars.

That's the price of technology.

As soon as China's five-axis machining center went on the market, the price of the world's five-axis machining center had to be reduced. This is a very normal thing. The five-axis machining center produced by Jiuyi Heavy Industry will not be announced until Hannover, Germany.

What they want to do is to hit 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 and see the use of those five-axis machining centers." Some of the equipment researched by the Jiuyi Research Institute was dragged to their production workshop by the 132 factory, and some of the other with better accuracy were in the production test workshop under the Jiuyi Research Institute.

This workshop is not only a variety of test products of the manufacturing research institute, but also undertakes difficult processing business outside.

This workshop is the place where the top processing capacity of the entire Jiuyi Group is located. Perhaps, it is also the first-class machining workshop in China. Many of the high-precision and complex parts of the test prototype of the 132 factory are processed in this workshop, and some of the super responsible parts processing of aerospace next door are also looking for the test workshop of the Jiuyi Research Institute.

Except for the young apprentices, any type of work in this is the most skilled and 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 conduct a technical competition in various types of work, just in June every year.

Skilled workers of different levels, and the employees in the production workshop under the research institute are the masters. Take on the challenge of front-line production skilled workers on the shop floor.

This is also equivalent to the entire group of skilled workers have a path to promotion.

Xinkaixing's technicians will also participate in the competition, every year, this competition is the most lively, even higher than the national skills competition. China's top skilled workers were all poached by Yun Fei. And they pay more attention to the training of skilled workers than any other company.

Skilled 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 in this are paid more than the managers. This is an indisputable fact.

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

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

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

The cost or anything is not considered at all.

24 hours a day, the entire production workshop is guarded by personnel on duty.

"Come and see how those five-axis productions are going, how about it? Nothing is a big deal, right? Yun Fei nodded at Fang Qiang.

This period of time is because of tackling key problems. These technicians and managers all have two dark circles under their eyes, and they all look sleep-deprived. After all, this project is too important, and it was done before the old man came to visit. After reading it, the old man is satisfied with how much benefit it can bring, this is something that everyone knows.

What's more, the order personally given by the big boss Yun.

"In addition to the previous period of processing quality is very unstable, now maybe after the run-in period, the quality is still relatively stable, the only problem is that the tool wear is too fast......," Fang Qiang accompanied Yun Fei and Sun Lin and others to the three-meter guide rail on the edge of the gantry five-axis machining center, while talking to Yun Fei about the problems they encountered.

"Tool consumption? Is it wearing out too fast or? Yun Fei asked suspiciously.

Jiuyi Materials' investment in knives is not small. In particular, the research of nano-scale cubic boron nitride has been started many years ago, far ahead of many domestic tool factories.

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

He knew that Yun Fei knew these things better than he did. Because Yun Fei himself is a professional in machining.

"In other words, the tool is not wear-resistant enough and will not last long, right?" Yun Fei directly grasped the key point, "What is the thickness of our tool coating?" ”

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

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

"Two wires to three wires are already thickened, and there is no problem with dry aluminum alloys, but titanium alloys, high-temperature alloys, and stainless steel are difficult to process materials at all. I have tried all kinds of cutting parameters......" Fang Qiang said with a sad face.

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

Coated tools, processing different materials require a variety of different materials, some use tungsten carbide, some use cubic boron nitride, and some use other superhard coatings, these are to increase the service life of the tool, so as to improve the efficiency of CNC machining.

From the very beginning, Jiuyi Material Factory has been studying nano-scale coating material technology from a strategic height, and it was only in 98 years that it began to make breakthroughs. Until now, none of these technologies have been completely stabilized.

The main source of profit of Jiuyi material lies in the ordinary high-speed tool steel cutter and cemented carbide business, and the coating tool and the advanced material tool such as cubic boron nitride, synthetic diamond cutter, ceramic cutter and so on have not achieved much success in the market.

"The statistics of the number of partitions of the service life of the tool have always been done, after all, the wear and tear is very slight, especially for the processing of easy-to-process materials such as aluminum alloy, the tool basically does not have too much wear, but the processing quality still has two to three filaments of fluctuation...... "Fang Qiang shook his head and said to Yun Fei.

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

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

"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 the problem of the tool, not the accuracy of the machine tool itself. That 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 was wrong here.

"These equipment are the first batch of prototypes to be transformed, the spindle or something is new before tackling the problem, and the control system and control method have also been changed, because more and more detailed processing numbers are to be obtained, so the CNC system has not been further upgraded...... Sun Lin's words made Yun Fei breathe a sigh of relief.

If it was this precision, this thing really couldn't be used to participate in the machine tool exhibition in Germany this year.

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

"Well, that's the one, it's currently being debugged, and all kinds of parameter settings, track running and so on have just begun. The machining accuracy of that one should be able to be controlled to within a trace of five......" Sun Lin said, pointing to the gantry-type machining center not far in front of him that had not yet been sprayed with paint. (To be continued......)
