Chapter 896: Really Difficult to Break Through in Technology (1)

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

For a long time, China has been a major importer of these top equipment manufacturing industries. Basically, there is no export. The three-axis machining centers that are exported are also because of low prices and poor performance. A large part of the exports are Taiwan CNC. There are not many domestic exports of machine tool factories.

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

The profit of high-end CNC machine tools is the largest.The Jiuyi Research Institute now produces a five-axis machining center for testing. The cost is about 3 million. If it is mass-produced, it can be controlled within 2.2 million.The lowest market price is 15 million, which is about 2 million US dollars.

Besides, it is only a woodworking machine.It is a light five-axis CNC machining center, and Jiuyi Research Institute initially deployed a heavy five-axis machining center.

These prices are different according to different models.Larger ones, higher precision ones, often cost tens of millions of dollars.When China just joined the World Trade Organization in 2001, in order to develop the J-20 aircraft and mass-produce the J-10, the Rongcheng 132 factory imported a five-axis five-linkage from the United States, the X-axis travel was 10 meters, and the Y-axis travel was two. Misi's heavy-duty CNC machining center has a straightness of 0.18 in the processing range, a repeat positioning accuracy of 0.04mm, and a processing accuracy of 0.05mm. The price is US$40 million!

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

According to professional speculation, the production cost of this equipment will never exceed six million US dollars.

This is the price of technology.

As soon as China's five-axis machining center went on the market, the entire world's five-axis machining center had to cut prices.This is very normal.The five-axis machining center produced by Jiuyi Heavy Industry will not be announced until Hanover, Germany participates in the exhibition.

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

"Let's go to the finishing workshop to see the usage of those five-axis machining centers." Some of the equipment studied by the Jiuyi Research Institute was dragged to their production workshop by the 132 factory, and some of the more accurate ones were in Jiuyi. A production test workshop under the research institute.

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

This workshop is the place with the top processing capacity of the entire Jiuyi Group, and perhaps the best machining workshop in China.Many of the high-precision and complex parts of the test prototypes in the 132 factory are processed in this workshop, and some super responsible parts of the aerospace next door are also in the test workshop of the Jiuyi Research Institute.

Except for the young apprentices, any of the types of work in it are the best in technology and the most experienced in the entire nine-one research institute.Moreover, in order to ensure that the technical level of the workers is the highest in the entire group company, every year the company will conduct a technical competition in various types of work, in June of each year.

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

This is equivalent to a way for the technical workers of the entire group company to get promoted.

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

Skilled workers will never be upgraded to management because of their good skills, unless the top skilled workers who are about to retire, they are usually responsible for patrolling the production workshop and providing technical guidance.

It is an indisputable fact that the wages of skilled workers are higher than those of managers.

"Boss, why did you have time to come here today?" As the director of the machining and finishing workshop of Jiuyi Heavy Industry at first, Fang Qiang, because of his outstanding personal ability, has two finishing workshops of Jiuyi Heavy Industry. The production test workshop of the research institute.

During this period of time, because the entire research institute was engaged in public relations five-axis linkage and automobile automatic production lines and supporting robots, his workshop director, who was in charge of several workshops, put the main energy in the production test workshop on the research institute's side.

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

The cost is simply not considered.

There are staff on duty in the entire production workshop 24 hours a day.

"Come and see the production situation of those five-axis, how about it? There is no big problem, right?" Yun Fei nodded to Fang Qiang.

During this period of research, these technicians and managers were all wearing dark circles under the eyes, and they all looked like lack of sleep.After all, this project is too important, and it was worked out before the old man came to visit. After seeing the old man, he was satisfied with how much benefit it can bring. This is something everyone knows.

What's more, the order given by Boss Yun himself.

"Except that the machining quality was very unstable in the previous period, it may be past the running-in period, and the quality is still relatively stable. The only problem is that the tool wear is consumed too quickly..." Fang Qiang accompanied Yun Fei and Sun Lin and others. Walking towards the gantry-type five-axis machining center with a three-meter guide rail on the far end, they each talked to Yunfei about their problems.

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

The investment of Jiu Yi materials on the tool is not small.Especially the research of nano-scale cubic boron nitride has been started many years ago, and it is far ahead of many domestic tool factories.

"The main reason is that the processing time is too long, and our tools can't bear it. Even the imported coated tools are not very effective..." Fang Qiang explained to Yunfei.

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

"That is to say, the tool is not wear-resistant enough, and the use time is not long?" Yunfei immediately grasped the key point, "What is the thickness of our tool coating?"

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

Those who sell machine tools must test out these data and give the customer a range of parameters 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. Dry aluminum alloy is no problem, but difficult-to-machine materials such as titanium alloy, high-temperature alloy, and stainless steel are not good at all. Various experiments on cutting parameters have been tried..." Fang Qiang frowned To say.

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

Coated tools, processing different materials requires a variety of different materials, some use tungsten carbide, some use cubic boron nitride, and some use other super-hard coatings, these are to increase the service life of the tool, thereby Improve the efficiency of CNC machining.

From the very beginning, the Jiuyi Material Factory has been researching nano-scale coating material technology at a strategic height, and it was only in 1998 that it began to make breakthrough progress.Up to now, these technologies have not completely stabilized.

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

"Division data statistics of tool life are always being done. After all, the degree of wear is very slight, especially for easy-to-machine materials such as aluminum alloy. The tool basically does not wear too much, but the machining quality still has two To the three-wire fluctuation..." Fang Qiang shook his head and said to Yun Fei.

"Aerospace aluminum is also relatively hard. Is it possible that the tool is worn out? The side or bottom edge of the tool is used?" Yun Fei frowned and asked.

If the tool is not worn and the machining quality fluctuates in this 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 Yunfei meant, and they also hoped that it was the problem of the tool, not the accuracy of the machine itself.This way they don't have to work overtime day and night.

Hope is good, 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. Spindles and everything are replaced with new ones before tackling key problems. The control system and control methods have also been changed, because more and more detailed processing data are needed. Therefore, the CNC system has not been upgraded..." Sun Lin's words made Yun Fei a sigh of relief.

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

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

"Here, it's that one. It's currently undergoing debugging. We just started to do various parameter settings, track running and so on. The processing accuracy of that one should be able to control to within a wire of five..." Sun Lin pointed to the front. Said the gantry-type machining center in the distance that has not been painted.
