"Since there are some things that state-owned enterprises can't do well. Then it's time for us private companies to give it a try. Fan Wuxian said at the subsequent video conference of the senior management of Fan's Investment Group.

According to the original plan, Fan Wuxian planned to take the extreme route, that is, to abandon the middle route, and directly put the company's offensive direction in terms of precision and breadth, and strive to win several major projects in this regard.

Many people think that the level of domestic machining is not as good as that of foreign countries, but China's machinery and equipment exports are not small, why does this happen?

In fact, Fan Wuxian sat on this issue to investigate, as early as six years ago, Jinan Machine Tool Factory production of gantry milling machine was exported to Japan, and for Japan's Mitsubishi Heavy Industries processing large equipment bed, workbench, etc., from a design point of view, Japan's Mitsubishi Heavy Industries design requirements are higher than the design requirements of domestic enterprises, but through domestic process improvement, it can be done.

For example, the hole distance tolerance of the screw hole for fastening is 0.1 millimeter, and in the design and processing habits of domestic enterprises at that time, there was no concept of marking tolerance, but only free tolerance. For another example, after drilling a hole, it is not allowed to move the position, but to replace the drill bit in the original position and install the tap. Tapping is immediate, which ensures a consistent thread depth around the screw hole.

It is precisely because of these almost strict and reasonable requirements of the Japanese that the finished workpiece is fully qualified. On the other hand, there are no such strict requirements for the processing parts made for domestic enterprises, especially in the processing process, the arbitrariness is very strong, and the design scope is seriously beyond the scope of the design, and in the end, the designers do not know whether the design accuracy is not enough or the processing accuracy is not enough.

Therefore, Fan Wuxi's conclusion for this survey is that the domestic design level is one grade higher than the processing level, and the real reason for the insufficient processing level is not that the processing equipment cannot be reached, nor that the level of workers cannot be reached, but that the quality awareness of processing workers is not enough.

Looking at the level of the domestic cold rolling mill, many experts under Fan Wuzhi have seen the design drawings of many domestic rolling mills, and generally believe that from the design point of view, the design accuracy is enough, and the processing level of domestic processing equipment and workers can also be done, but after the real processing is completed, when the on-site installation and commissioning are completed, many problems will be found, and in the process of solving these problems, it is often found that the machining accuracy does not meet the design requirements and the problems arise, and some even exceed the design accuracy dozens of times.

Therefore, Fan Wuzhi came to a conclusion, that is, domestic equipment manufacturers, when providing customers with high-precision equipment, need to consider whether the company's production process control can meet the design requirements, without having to spend great efforts to solve the problem of design accuracy. As long as the processing workers do it in strict accordance with the requirements of the drawings, and as long as the assembly workers install it in strict accordance with the requirements of the drawings, there will be no major problems with the accuracy and reliability of the equipment.

"The key to it. It's still a human problem. Fan Wuxian said to everyone.

In the past, there were many skilled old technicians in the Pingyuan factory, and they did the work that ordinary people couldn't do, but this technology is not generalizable, and it is often done by relying on their own feelings, which leads to the fact that although there is no problem with the combination of parts, it is very problematic to take it to mass production.

What Fan Wuxian needs is a large number of new technicians who work in strict accordance with the operating procedures, and a new generation of technology-based technicians who can skillfully operate CNC machine tools to complete various difficult controls, which makes him face a big problem, so many technicians, where to find them?

After so many years of operation, Panshi Heavy Industry has trained thousands of senior technicians for the entire Fan's Investment Group, and after the Ukrainian experts were absorbed, the scale of the entire Panshi Heavy Industry has exceeded 30,000 people, and now it is also a well-known enterprise in China.

This time, Fan Wuxian plans to build a new military industrial enterprise, and he is also considering to transfer a part of the technical force from Panshi Heavy Industry, plus recruit a large number of workers from the society, and then dig some experienced senior technicians from major foreign companies to carry out technology dissemination. In this way, it is estimated that the company will be able to pull up in a year.

During this period of time, I started to collect intelligence materials on various military industrial enterprises in various ways, starting with problems that are relatively easy to solve, opening up one or two blank projects in China, reaching the advanced level in China in about three years, and striving to be able to compete with some large foreign enterprises in about five years.

With the growing needs of domestic construction, China is becoming the world's largest consumer of machine tools, will also become the world's largest importer of CNC machine tools, the country is currently improving the numerical control rate of machining equipment, this year the national numerical control rate of machining equipment is about five percent, is striving to reach more than 20 percent in five years.

Turning, milling, planing, grinding, boring, drilling, EDM, shearing, bending, laser cutting, etc. are all machining methods, the so-called machining, is to process metal blank parts into the required shape, including dimensional accuracy and geometric accuracy of two aspects, can complete the above functions of the equipment are called machine tools, CNC machine tools are developed on ordinary machine tools, CNC means digital control.

After the machine tool is equipped with a CNC system, the machine tool becomes a CNC machine tool. Of course, the development of ordinary machine tools to CNC machine tools is not just a simple installation system, for example, from the milling machine to the machining center, the structure of the machine tool has changed, the most important thing is to add a tool magazine, greatly improve the accuracy. The most important function of the machining center is the function of milling, boring and drilling.

Generally speaking, the CNC equipment is mainly an exponential lathe and machining center.

At present, various categories of CNC machine tools in China can be produced, and the level is uneven, some are at the world level, and some are ten to twenty years behind foreign countries. But with strong support from the state, catching up is not a problem.

For example, the acquisition of some foreign machine tool companies, as long as they can vigorously digest each other's technology, can shorten a lot of gaps. In recent years, with the rise of Chinese manufacturing, many European enterprises have closed down or been merged, and due to the economic downturn in Japan, there are also many machine tool manufacturers in the eighties who are very famous for the collapse of machine tool manufacturers, although these companies have collapsed, but there are 3,000 nails in the broken ship, and the talents and technology left behind can still be used.

When it comes to this problem, Wu Zhi Xiaoji said to Fan Wuxi, "At present, Germany and Switzerland have the highest precision of machine tools, and on the whole, Germany has the highest level, Japan has the largest output value, and the machine tool industry in the United States is average." ”

The numerical control system is composed of displays, controller servos, servo motors, and various switches and sensors. At present, the world's three largest manufacturers are Japan's Fanak, Germany's Siemens, Japan's Mitsubishi, and the rest are France's Twist, Spain's Van Gogh, etc., the domestic CNC system has just begun, the level of quality is average, and the high-grade systems are all imported.

"There is no CNC machine tool on the table in China, although the software problem is easy to solve, but the gap is mainly in the electrical hardware, the quality and accuracy can not meet the standard. The problem of high failure rate cannot be solved. Fan Wuxian thought of this and couldn't help but say, "But it is still possible to get some simple CNC machine tools first, after all, there is also a large market demand for these things." As for how to make advanced CNC machine tools, it is not achieved overnight, and it takes the test of time. ”

In fact, look at the level of a machine tool, it depends on its repeated positioning accuracy, if the repeated positioning accuracy of a machine tool can reach 0.005mm, then it is a high-precision machine tool, below 0.005mm, it is an ultra-high-precision machine tool, high-precision machine tool. It is necessary to have the best bearings and lead screws.

In order to process high-precision parts, not only the machine tool is required to have high precision, but also a good process method, a good fixture, and a good tool, all of which are indispensable.

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

Although the state has been allocating funds to support state-owned enterprises, it has not made great efforts on the most important basis of CNC machine tools, and military enterprises have also fallen into a survival dilemma because they do not have much demand.

This time, because of the bombing of the embassy, the high-level people in China suddenly woke up to the fact that if they don't have any military industrial strength, they will still be backward and beaten, and they can only make people slap you in the face.

Although the country has made a little money in the past two years, compared with so many state-owned enterprises in the country, it is still like a drop in the bucket, and there is no way to let them fend for themselves, but for military enterprises, especially those more important military enterprises, it is no longer allowed to indulge.

According to Fan Heng and Fan Wuxi, the state is planning to allocate funds to military enterprises and support them, but there is no very clear policy on the issue of CNC machine tools.

Although Fan Wuxian wants to point out this problem, I believe that many people will disagree, and now the plan is to let himself do this work first, as long as there are mature products, and when the military industrial enterprises want to start eliminating ordinary equipment and carrying out large-scale technological transformation, then their own efforts will be counted.

At least a large amount of foreign orders can be saved, so that foreigners will not use their second- or third-rate CNC machine tools to defraud domestic enterprises of large sums of real money, which can be regarded as a merit.

Being able to produce advanced CNC machine tools and equipment is the foundation for a country's industry to become truly strong.

There are no pop-ups
