3 Chapter 730 The Real Basics

"Since some things are not done well by state-owned enterprises, we should give them to our private enterprises Kang, Wu." Fan Wubing said at the subsequent high-level video conference of Fan Investment Group.

According to Yuan Bin's plan, Fan Wubing plans to take the extreme route, that is, abandon the intermediate route, directly focus the company's offensive direction in terms of accuracy and breadth, and strive to win several major projects in this area.

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

In fact, Fan Wubing has investigated 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 beds and tables of large equipment for Mitsubishi Heavy Industry in Japan. From a design perspective, the design requirements of Mitsubishi Heavy Industry in Japan are higher than those of domestic companies, but through domestic process improvements, it can be achieved.

For example, the tolerance of the screw holes for tightening is one millimeter at zero point. At that time, in the design and processing habits of domestic enterprises, there was no concept of tolerance, but it was just free tolerance. For example, after drilling the hole, it was not allowed to move the position, but instead replaced the drill bit at the original position, installed a tap, and tapped immediately. This ensures the consistency of the thread depth around the screw hole.

It is precisely because of these almost harsh and reasonable requirements of the Japanese that the finished workpieces are completely 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, which is very arbitrary and seriously exceeds the design scope. In the end, the designers do not know whether the design accuracy is insufficient or the processing accuracy is insufficient.

Therefore, Fan Wubing concluded that the domestic design level depends on the level of processing level, and the real reason for insufficient processing level is not that the processing equipment cannot be achieved, nor that the level of workers cannot be achieved, but that the quality awareness of processing workers is insufficient.

Let’s look at the level of domestic cold rolling mills. Many experts under Fan Wubing have read many design drawings of domestic rolling mills. They generally believe that from the perspective of design, the design accuracy is sufficient, and the processing level of domestic processing equipment and workers can be fully achieved. However, after the processing is completed, when the site is installed and tested, many problems will be found. In the process of solving these problems, it is often found that the processing accuracy does not meet the design requirements, and some even exceed the design accuracy several times.

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

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

Fan Wubing himself was also deeply touched about this issue. In the past, there were many skilled old technicians in the plain factory. They could do all the work that most people could not get. However, this technology is not popularizable and is often completed by their own feelings. This leads to the fact that there is no problem in combining parts, but it is very problematic to use it for mass production. All chapters are invited.

What Fan Wubing needs is a large number of new technicians who strictly follow operating procedures, and a new generation of scientific and technological technicians who can skillfully operate CNC machine tools to complete various difficult controls, which puts him in a big problem. Where can I find so many technicians?

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

This time Fan Wubing plans to build a new military-industrial enterprise, and considers drawing some technical forces from Panshi Heavy Industry, and recruiting a large number of employees from society, and then digging some experienced senior technicians from major foreign companies to spread technology. In this way, the company will probably be able to gather in one year.

During this period, I started to collect information about various military-industrial enterprises in many ways, and first started to start one or two blank projects in China from relatively easy-to-solve problems. It took about three years to reach the advanced domestic level and strive to be able to compete with some large foreign companies in about five years. I think it is very sure.

With the increasing demand for domestic construction, China is becoming the world's largest consumer of machine tools and 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%. We are striving to reach more than 20% in five years.

"Practice small planing, grinding, edge, drilling, electric spark, shearing, bending, and cutting" "One-foot mechanical processing method, the so-called mechanical processing is to process metal blank parts into the required shape. It includes two aspects: dimensional accuracy and geometric accuracy. Equipment that can complete the above functions are called machine tools. CNC machine tools are developed on ordinary machine tools. CNC means digital control.

After installing a CNC system on the machine tool, the machine tool becomes a CNC machine tool. Of course, the development of ordinary machine tools to CNC machine tools is not just as simple as installing a system, such as from a sharp bed to a machining center. The structure of the machine tool has changed. The most important thing is to add a tool magazine, which greatly improves the accuracy. The main function of the machining center is the functions of milling, clanging, and drilling.

The CNC equipment generally refers to CNC lathes and machining centers.

Currently, CNC machine tools of various types in China can be produced, with uneven levels. Some are at the world level, and some are ten to twenty years behind foreign countries. However, if there is strong support from the country, it will not be a problem to catch up.

For example, acquiring some foreign machine tool companies. As long as they can vigorously digest the other party's technology, a lot of gaps can be shortened. In recent years, with the rise of Chinese manufacturing, many European companies have gone bankrupt or merged. Due to the early economic downturn, there are also many machine tool manufacturers who are very famous in the 1980s. Although these companies have collapsed, there are still 3,000 nails in the broken ship, and the talents and technologies left behind can still be used.

When talking about this issue, Wushe Xiaoji said to Fan Wubing, "At present, Germany and Switzerland have the highest machine tools. In total, Germany has the highest level and Japan has the largest output value.

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

In terms of CNC systems, it is composed of displays, controller servo, servo motor, various switches and sensors. Currently, the three largest manufacturers in the world are Japan's Fenac, Germany's Siemens, Japan's Mitsubishi, and the rest are France's Torm, Spain's Van Gogh, etc. The domestic CNC systems have just started. The level and quality are average, and all high-end systems are imported.

"There are no CNC machine tools in China that can be used on the table. Although the software problem is easy to solve, the gap is mainly in electrical hardware. If the quality accuracy does not meet the standard, the problem of high fault strings cannot be solved." Fan Wubing thought of this and couldn't help but say, "But it is still competent to get some simple CNC machine tools first. After all, these things also have a large market demand. As for how to make advanced CNC machine tools, it is not achieved overnight, and it takes a test of time."

In fact, the level of a machine tool depends on its repeated accuracy. If the repeat positioning accuracy of Yishou machine tool can be achieved, it is a high-precision machine tool. In the strong case, it is an ultra-high-precision machine tool. A high-precision machine tool must have the best bearings and wire bearings.

To process high-precision parts, not only high machine tool accuracy is 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 thought a little deeply.

Although the country has been allocating funds to support state-owned enterprises, it has not put in much effort on the most important basis of CNC machine tools, and military-industrial enterprises have also fallen into survival difficulties due to insufficient demand.

This time, the domestic senior officials have awakened because of the bombing of the embassy. If they have no military strength, they will still be behind and be beaten, and they will only be slapped you in vain.

Although the country has 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. There is no way for them to survive on their own. However, military-industrial enterprises, especially those more important military-industrial enterprises, cannot be indulged.

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

Although Fan Wubing really wants to point out this problem, I believe many people will disagree. Now the plan is to get this job done first. As long as you have mature products and military enterprises have to start eliminating ordinary equipment and conducting large-scale technological transformation, then your skills have been put into practice.

At least a large amount of foreign orders can be saved. It is not enough for foreigners to use their second- and third-rate CNC machine tools to defraud domestic companies of large amounts of real money. This is also a merit.

Being able to produce advanced CNC machine tools is the basis for a country's industry to become truly powerful.
