Super Weapon Exchange System

Machine tools are the mother machine of industrial processing. The use of machine tools can be regarded as the beginning of the era of machine manufacturing. The number of machine tools in a country can be used to measure the level of machine tools in this country.

Metal cutting, drilling, stamping, etc., various operations are carried out by corresponding machine tools. Now, the entire 4447 factory has a large number of machine tools and a large number of experienced masters.

However, no matter how clever the craftsmanship of these masters are, they cannot machine parts with higher precision because of the limitations of the machine tool.

Any mechanical processing must pay attention to an important data, which is the processing accuracy. For example, the processing accuracy is 1 mm, that is to say, the workpiece is designed to be 10 mm, but the output may be 9 mm or eleven. Mm.

It can be seen that this error is not small. If the machining accuracy becomes 0.1 mm, the result may be 9.9 mm or 10.1 mm. At this time, the machining accuracy is very high.

Now, the most urgent need to solve in the factory is the processing of high-pressure oil pumps. No matter how the experienced masters work hard, the finished product will have too much error. If it is assembled, it will be too thick and the friction resistance will be large, or Because it is too thin and leaks oil, it cannot be used at all.

After all, civilian heavy trucks need to pay attention to the cost of use, and the fuel consumption rate must be lowered.

This requires CNC machine tools.

No matter how skilled the workers are, as long as they use their own hands, there will always be errors, and if they are controlled by a computer, then human factors can be eliminated, and the computer will not make accidental errors.

The other aspect is multi-axis linkage.

This is the best way to really improve machining accuracy.

General workpieces may need to be processed from several directions. Each time the processing direction is changed, the processed workpiece needs to be fixed again. Every time the fixed position is changed, errors will inevitably be brought about.

If several turning tools can be used at the same time to process from several faces together, this problem can be avoided. The workpiece does not move during the entire processing, and there will be no errors in each movement.

Especially for processing complex curved surfaces, only multi-axis linkage can be processed.

At this time, no matter how skilled the workers are, they must be controlled by computers.

All of this has emerged with the development of technology. In the middle of this century, with the development of electronic technology, automatic information processing, data processing and the emergence of electronic computers have brought new concepts to automation technology, using digital signals Controlling the movement of the machine tool and its processing has promoted the development of machine tool automation.

It was first realized in the early 1940s by Pearsons, a small aircraft industrial contractor in North Mytchian, Eagle Country. When they are manufacturing the frame of the aircraft and the rotating wing of the helicopter, they use a fully digital computer to process the data of the wing processing path, and take into account the impact of the tool diameter on the processing path, so that the processing accuracy reaches ±0.0381 mm. The highest level at the time.

Ten years later, Eagle Country MIT installed a set of experimental numerical control system on a vertical milling machine, and successfully realized the simultaneous control of three-axis motion. This CNC machine tool is called the first CNC machine tool in the world.

Compared with them, the CNC technology of Han has not started slowly, almost synchronized with foreign countries. The development started in the 1950s, and the first CNC machine tool was developed in 1958.

However, for well-known reasons, how could there be advanced CNC machine tools under that special historical background!

It's just to follow the trend, lack of understanding of the characteristics and development conditions of CNC machine tools. Under the circumstances of poor quality of personnel, weak foundation, and inadequate supporting parts, they rushed up and down. There have been three ups and downs, and finally due to performance. It is not good enough to be used in production and stopped.

Except when we posted a big-character poster to promote our CNC machine tools to put a big satellite, it is impossible to carry out actual production.

Domestic CNC machine tools cannot be used at all, imported from abroad? On the one hand, we need precious foreign exchange reserves. On the other hand, foreign countries have also imposed a blockade on ourselves, so we can't import them at all. Only in the last few years has it eased down and made imports possible.

As long as Qin Guan said, it would definitely be possible, without having to worry about it.

At the same time, on the other hand, there is indeed no one who can operate CNC machine tools in the factory.

Most of the workers in the factory are not well-educated. When they entered the factory, they relied on the relationship and the roots of the red seedlings. Biho Ribala did not want to come, but was sent in instead.

To operate the machine tools, they are all taught by the master's words and deeds. They have no knowledge of physics, so they operate according to the experience taught by the master. After a long time, they will become familiar.

And CNC machine tools are troublesome. Without solid physics, machining and computer skills, one should never operate this machine well.

After all, in this era, most people have never seen a computer or touched a keyboard.

Specialized talents must be hired. If they are not available in China, they can only be hired from abroad. Those invited from abroad are only temporary, and we have to train our skilled workers.

"Okay, Qin Guan." Director Sun made a decision: "You are responsible for the machine tool, and I am responsible for finding a technician."

It is impossible for Qin Guan to do everything by himself. Others will definitely not be able to handle the machine tool. It is still possible to hire a mechanic at a high price.

"Qin Guan, when is your marriage scheduled?" After the other things were finished, Factory Manager Sun asked Qin Guan with a smile.

Qin Guan patted his head immediately, not good!

After coming back, I was busy with things in the factory, and actually forgot my marriage.

"I'll go back and discuss it." Qin Guan said: "Today's meeting, shall we stop here?"

Everyone smiled knowingly, are you thinking about going home and holding your wife?

Since he had already received the marriage certificate, Chen Yutong simply moved to Qin Guan's dormitory graciously. The single dormitory is so spacious and much better than his own.

However, after Chen Yutong’s parents came all the way from the south, Chen Yutong could only go back obediently. After all, in the eyes of the older generation, the marriage certificate is just a piece of paper. Only when the formal wedding is completed can the bridal chamber be married. what.

Next to Qin Guan's dormitory is Xiang Jing's dormitory. Xiang Jing initially occupied it very aggressively, but now, when Chen Yutong's parents arrived, this dormitory was given to them.

At this time, the dormitory was very lively, Xiang Jing was carrying the camera and was recording.
