3 Chapter 730 The Real Foundation

"Since there are some things that state-owned enterprises can't do well. Then we should let our private enterprises Kangwu." Fan Wuyao said in the subsequent video conference of the Fan Investment Group's senior management.

According to Yuanbin's plan, Fan Wuyi intends to take the radical route, which means to abandon the middle route and directly put the company's offensive direction in the two aspects of precision and breadth and strive to win several major projects in this area.

Many people think that the level of domestic machinery processing is not as good as that of foreign countries, but the export volume of China's machinery and equipment is not small. Why does this happen?

In fact, Fan Wubing has been investigating this issue. As early as six years ago, the gantry milling machine produced by Jinan Machine Tool Plant was exported to Japan and processed the bed and stop table of large equipment for Mitsubishi Heavy Industries in Japan. From a design perspective, Mitsubishi Heavy Industries, Japan The design requirements are higher than those of domestic enterprises, but it can be achieved through domestic process improvements.

For example, the pitch tolerance of the screw holes for fastening is 0.1 mm. At that time, in the design and processing habits of domestic enterprises, the concept of tolerance was not marked but free tolerance. For example, after drilling the hole, it is not allowed to move the position, but replace the drill bit at the original position and install the tap to tap immediately. This ensures the consistency of the thread depth around the screw hole.

It is precisely because of these nearly harsh reasonable requirements of the Japanese that the processed workpieces are fully qualified. On the other hand, the machining parts made for domestic enterprises do not have such strict requirements at all, especially the randomness in the machining process is very strong, and the design range is severely out of the design range to the end. The designer does not know whether the design accuracy is insufficient or the machining accuracy is insufficient.

Therefore, Fan Wubing's conclusion for this investigation is that the domestic design level is placed on the level of processing level and the real reason for the insufficient processing level is not that the processing equipment does not meet the level of the workers, but the quality awareness of the processing workers. not enough.

Let's look at the level of domestic cold rolling mills. Many experts under Fan Wubing have seen the design drawings of many domestic rolling mills. They generally believe that from a design perspective, the design accuracy is enough to use domestic processing equipment and the processing level of the workers. Many problems will appear during the test run. In the process of solving these problems, it is often that the machining accuracy does not meet the design requirements, and some of the problems are even several times the design accuracy.

Therefore, Fan Wubing came to the conclusion that domestic equipment manufacturers need to consider whether the production process control of their enterprises can meet the design requirements when providing high-precision equipment to customers without having to make great efforts to solve the design accuracy problem. As long as the processing workers strictly follow the requirements of the drawings, as long as the assembly workers strictly follow the requirements of the drawings, there will be no major problems with the accuracy and reliability of the equipment.

"The key is still the problem of people." Fan Wuyao said to everyone.

Fan Wubing himself is deeply touched on this issue. In the past, there were many skilled old technicians in the Pingyuan factory. They did all the jobs that most people couldn't take. But this kind of technology is not generalizable. It often depends on their own feelings. This has led to the fact that there is no problem in the combination of parts, but it is very problematic to take mass production. All chapters are here

What Fan Wubing needs is a large number of new-generation technicians who work strictly in accordance with the operating procedures. A new generation of technology-based technicians who can skillfully operate CNC machine tools to complete various difficult operations. This makes him face a big problem. Where can so many craftsmen go?

Panshi Heavy Industry has been operating for so many years. Instead, thousands of senior technicians have been trained for the entire small Fan Investment Group. After the Ukrainian experts were recruited, the scale of the entire Panshi Heavy Industry has exceeded 30,000. Now it is also a well-known enterprise in China.

This time Fan Wubing plans to build a new military industry enterprise is also considering drawing a part of the technical force from Panshi Heavy Industry, plus recruiting a large number of employees from the society, and digging some experienced senior technicians from major foreign companies to carry out technology dissemination. In this case, it is estimated that the enterprise can be started in a year.

During this period of time, I started to collect intelligence information from various military enterprises in various ways. First, I started one or two blank projects in the country from the relatively easy-to-solve problems. It is quite certain to reach the domestic advanced level in about three years and to be able to compare with some large foreign companies in about five years.

With the continuous growth of domestic construction needs. China is becoming the world's largest consumer of machine tools and it will also become the world's largest importer of CNC machine tools. At present, the country is increasing the CNC rate of machining equipment. This year, the CNC rate of machining equipment nationwide is about 5%. It is striving to reach more than 20% in five years. "Practicing small planing, grinding, sharpening, drilling, electric sparks, shearing, bending, and rice cutting disadvantages" is a mechanical processing method. The so-called mechanical processing is to process metal blank parts into the required shape. Contains two aspects of dimensional accuracy and geometric accuracy. The equipment that can complete the above functions is called machine tool numerical control machine tool, which is the numerical control developed on the ordinary machine tool, which means digital control.

After installing the CNC system on the machine tool, the machine tool becomes a CNC machine tool. Of course, the exhibition of ordinary machine tools to CNC machine tools is not just a simple installation of systems, such as the exhibition from sharp machines to machining centers. The structure of the machine tool has changed. The most important thing is that the tool magazine has been added to greatly improve the accuracy. The main function of the machining center is the functions of milling, knocking and drilling.

Generally speaking, the numerical control equipment is mainly index-controlled lathes and machining centers.

The current domestic production levels of various types of CNC machine tools are uneven. Some are at the world level and some are lagging behind foreign countries by ten to twenty years, but if there is strong support from the country, it will not be a problem to catch up.

For example, the acquisition of some foreign machine tool companies. As long as we can vigorously digest the technology of the other party, we can shorten many gaps. In recent years, with the rise of Chinese manufacturing, many European companies have closed down or were merged due to the economic downturn. There are also many well-known machine tool manufacturers in the 1980s. Although these companies have collapsed, there are still three thousand talents and skills left by the broken ship that can still be used.

When talking about this issue, Wushe Xiaoji said to Fan Wuyao: "The machine tools in Germany and Switzerland have the highest precision combined, Germany has the highest level, and Japan has the largest output value.

The machine tool industry in the United States is average. "

The numerical control system is composed of display, controller servo, servo motor, and various switches and sensors. At present, the three largest manufacturers in the world are Japan's Nake, Germany's Siemens, Japan's Mitsubishi, and others, as well as France's Twum, Spain's Van Gogh, and other domestic CNC systems. All of them are imported.

"There is currently no CNC machine tool that can be used on the table. Although the software problem is easy to solve, the main difference lies in the quality and accuracy of the electrical hardware. If the quality and accuracy of the electrical hardware are not up to the standard, the problem of high fault string cannot be solved." Fan Wubing thought of this. I couldn't help but say, "But it is still capable of getting some simple CNC machine tools first. After all, these things also have a lot of market demand. As for how to make advanced CNC machine tools, it will not take the test of time to do it overnight."

In fact, look at the level of a machine tool. It depends on its repetitive positioning accuracy. If the repetitive positioning accuracy of a beast machine tool can reach higher than that, it is a high-precision machine tool, and Wangxia is a high-precision machine tool. High-precision machine tools must have the best bearings and wires.

However, to process high-precision parts, not only the high precision of the machine tool, but also a good process method, a good fixture, and a good tool are indispensable.

Thinking of this, Fan Wubing couldn't help but touch his forehead, thinking deeply.

Although the state has been appropriating funds to support state-owned enterprises. However, no great effort has been made on the most important foundation of the industrial enterprise of CNC machine tools, and the military industry enterprises are in a difficult situation of survival due to not much demand.

This time because of the bombing of the embassy. Only then did the domestic high-levels wake up to the realization that they have no military strength or are lagging behind and being beaten. They can only make people slap you in vain~www.wuxiamtl.com~Although the country has a little money in the past two years, it is relatively good. So many state-owned enterprises across the country. There is still no way to allow them to fend for themselves like a drop in the bucket. It's just that military industry enterprises, especially those more important ones, can no longer be indulged.

According to Fan Heng and Fan Wubing, the state is planning to provide key funding support for military industrial enterprises, but on the issue of CNC machine tools. But there is no clear policy.

Although Fan Wubing wanted to point out this problem very much. But I believe many people will disagree. Now the plan is to let yourself do this work first, as long as there are mature products and military industry companies start to eliminate common equipment and carry out large-scale technological transformations. Even if his own kung fu has come down.

At least large foreign orders can be saved. It is a great merit not to let foreigners use their second- and third-rate CNC machine tools to defraud domestic companies of large sums of real money.

Able to produce advanced CNC machine tools. It is the foundation on which a country's industry can truly become stronger.
