Chapter 730 The Real Foundation

3Chapter 730 The real foundation

"Since there are some things that state-owned enterprises cannot handle well, then it is time to give them to our private company Kangwu." Fan Wubing said at the subsequent video conference of Fan Investment Group's top management.

According to Yuan Bin's plan, Fan Wubing planned to take an extreme route, which meant abandoning the middle route and directly focusing the company's attack direction on both precision and breadth, striving to win several big projects in this area.

Many people think that the level of domestic mechanical processing is not as good as abroad. But China’s export volume of machinery and equipment is not small. Why does this happen?

In fact, Fan Wubing has conducted an investigation on this issue. As early as six years ago, the gantry milling machine produced by Jinan Machine Tool Factory was exported to Japan and processed the bed and worktable of large equipment for Japan's Mitsubishi Heavy Industries. From a design perspective, Japan's Mitsubishi Heavy Industries The design requirements are higher than those of domestic enterprises, but they can be achieved through domestic process improvements.

For example, the hole spacing tolerance of fastening screw holes is 0.1 mm. At that time, there was no concept of tolerance marking in the design and processing habits of domestic enterprises. It was just a free tolerance. Another example is that after drilling a hole, you are not allowed to move the position, but replace the drill bit at the original position and install the tap for tapping immediately. This ensures the consistency of thread depth around the screw hole.

It is precisely because of these almost harsh and reasonable requirements of the Japanese that the processed workpieces are fully qualified. On the other hand, the processed parts made for domestic enterprises do not have such strict requirements at all. Especially during the processing process, they are very random and seriously exceed the design scope. In the end, the designers do not know whether the design accuracy or the processing accuracy is insufficient.

Therefore, Fan Wubing concluded from this survey that the domestic design level is at the same level as the processing level, and the real reason for the insufficient processing level is not that the processing equipment is not up to par, nor that the workers are not up to par, 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 many design drawings of domestic rolling mills and generally believe that from a design perspective, the design accuracy is sufficient and can be achieved using domestic processing equipment and the processing level of workers. However, after the actual processing is completed, it must be installed and installed on site. During the test run, many problems will be discovered. In the process of solving these problems, it is often found that the processing accuracy does not meet the design requirements. Some problems even exceed the design accuracy by several times.

Therefore, Fan Wubing came to the conclusion that when providing high-precision equipment to customers, domestic equipment manufacturers need to consider whether the company's production process control can meet the design requirements without spending 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 install the equipment strictly according to the requirements of the drawings, there will be no major problems with the accuracy and reliability of the equipment.

"The key is still the human problem." Fan Wubing said to everyone.

Fan Wubing himself has deep feelings about this issue. In the past, there were many skilled old technicians in the Pingyuan factory. They could do jobs that ordinary people could not do. However, this kind of technology is not scalable and they often rely on their own feelings. This has led to the problem that although there is no problem in combining the parts, it is very problematic to use it for mass production.

All chapters are welcome

What Fan Wubing needs is a large number of new technicians who work strictly in accordance with operating procedures. A new generation of technological technicians who can skillfully operate CNC machine tools to complete various difficult operations. This puts him facing a big problem. Where can we find so many technicians?

Panshi Heavy Industries has gone through so many years of operation. On the contrary, Fanshi Investment Group has trained thousands of senior technicians for the entire Jinjin. After the Ukrainian experts were absorbed, the scale of the entire Panshi Heavy Industry has exceeded 30,000, and it is now a well-known enterprise in China.

This time Fan Wubing planned to build a new military industry enterprise and also considered transferring some technical forces from Panshi Heavy Industry, recruiting a large number of employees from the society, and poaching some experienced senior technicians from major foreign companies to carry out technology dissemination. In this case, it is estimated that the company will be up and running within a year.

During this period of time, I started from various aspects to collect intelligence information on various military industrial enterprises, starting with problems that were easier to solve and started one or two blank projects in the country. It will take about three years to reach the domestic advanced level and it will take about five years to be on par with some large foreign companies. It is quite certain.

As domestic construction needs continue to grow. China is becoming the world's largest consumer of machine tools and will also become the world's largest importer of CNC machine tools. Currently, the country is increasing the CNC rate of mechanical processing equipment. This year, the CNC rate of mechanical processing equipment nationwide is about 5%. We are striving to reach more than 20% in five years. "Practice small planing, grinding, sharpening, drilling, EDM, shearing, bending, and laser cutting." One-stop mechanical processing methods. The so-called mechanical processing is to process metal blank parts into the required shape. It includes both dimensional accuracy and geometric accuracy. Equipment that can complete the above functions are called machine tools. CNC machine tools are CNC developed on ordinary machine tools, which means digital control.

After installing a CNC system on a machine tool, the machine tool becomes a CNC machine tool. Of course, the development of ordinary machine tools into CNC machine tools is not as simple as installing a system, such as the development from a sharpening machine to a machining center. 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 functions of the machining center are milling, hammering and drilling.

Generally speaking, CNC equipment is mainly index-controlled lathes and machining centers.

The current domestic CNC machine tools of various categories have varying production levels. Some are at world level and some are ten to twenty years behind foreign countries. But if there is strong support from the country, catching up will not be a problem.

For example, acquire some foreign machine tool companies. As long as we can vigorously digest the opponent's technology, we can shorten the gap a lot. In recent years, with the rise of Chinese manufacturing, many European companies have closed down or been merged due to the early economic downturn. There are also many machine tool manufacturers that were famous in the 1980s. Although these companies have collapsed, the talents and technologies left behind by Three Thousand Nails can still be used.

When talking about this issue, Wushe Xiaoji said to Fan Wubing, "Currently, Germany and Switzerland have the highest machine tool accuracy. Germany has the highest level and Japan has the highest output value."

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

The CNC system is composed of a display, controller servo, servo motor, and various switches and sensors. At present, the three largest manufacturers in the world are Japan's NAC, Germany's Siemens, and Japan's Mitsubishi. The others, including France's Torm and Spain's Van Gogh, only have domestic CNC systems, and all high-end systems of average quality are imported.

"There are currently no CNC machine tools that are worthy of being marketed in China. Although software problems are easy to solve, the main gap lies in the quality and accuracy of electrical hardware. If the quality and accuracy are not up to standard, the problem of high fault clusters cannot be solved." Fan Wubing thought about this. I couldn't help but say, "But it's still possible to get some simple CNC machine tools first. After all, there is a lot of market demand for these things. As for how to make advanced CNC machine tools, it is not something that can be accomplished overnight. It will take time."

In fact, it depends on the level of a machine tool. It depends on its repeatability. If the repeatability of a beast machine tool can reach 100%, then it is a high-precision machine tool. If it is high, it is a high-precision machine tool. High-precision machine tools must have the best bearings and wire handles.

To process high-precision parts, not only high-precision machine tools are required, but also good process methods, good fixtures, and good tools are indispensable.

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

Although the state has been allocating funds to support state-owned enterprises. However, no great efforts have been made on CNC machine tools, the most important foundation of industrial enterprises, and military industrial enterprises are in survival difficulties because there is not much demand.

This time it was because of the bombing of the embassy. Only then did the top leaders in the country suddenly realize that if you don’t have any military strength, you will still fall behind and be beaten, and people can only give you a big slap in the face.

Although the country has made a little money in the past two years, compared with so many state-owned enterprises across the country. There is no other way to let them fend for themselves like a drop in the bucket. But for military-industrial enterprises, especially those more important military-industrial enterprises, they can no longer indulge.

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

Although Fan Wubing really wanted to point out this issue. But I believe many people will disagree. The current plan is to get this work started first, as long as there are mature products and the military industry enterprises begin to eliminate ordinary equipment and carry out large-scale technological transformation. Then your own efforts will be considered adequate.

At least large overseas orders can be saved. It would be a great merit to prevent foreigners from using their second- and third-rate CNC machine tools to defraud domestic companies of large sums of real money.

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