Guderian and others from the Soviet Union signed contracts with Camat for a minimum of more than 10 years.

Therefore, many people follow the translator on the train to learn Chinese, but unfortunately, Chinese is too difficult, more than 20 days, practice so that the tongue is numb, except for those who are younger can barely carry out the simplest and basic communication, they are forty or fifty years old, they can only learn the simplest common words, so just say these few words, Guderian is full of redness.

Even assembling and disassembling the most compact crankshaft grinding machine in the entire Soviet Union was not as difficult as this.

"My name is Zhao Binbiao, and I am the master fitter here." Zhao Binbiao stretched out his hand to Guderian and introduced himself to the Soviet, and this guy would be his partner in the future. In order not to fight each other in future work, they must reach an agreement between the leaders of China and the Soviet Union.

Otherwise, if the work in the future is delayed or something, not to mention whether it will be severely punished, at least the bonus will be much less. The wage system in the new factory has come out, and in addition to the basic salary, the most part they get in the future is bonuses. How does the bonus come about? It's not just about how much work each person does, it's about the whole team. The assessment of the team accounts for 60% of the entire bonus.

In other words, if a team has a problem with only one person, everyone will only get 40% of the bonus. It's about how much you earn in the future.

"Zhao ......" Guderian also stretched out his hand, and the two large rough hands were tightly clasped together. However, the pronunciation of Zhao Bingbiao's name was too difficult for Guderian, and he only said Guderian's surname, and his face was flushed, and there was no way to pronounce the two words Bingbiao.

Regarding Guderian's ability to say his surname, Zhao Bingbiao felt that even if the Soviet big brother in front of him couldn't remember his name, he couldn't blame him. If you want to blame, you can only blame your parents. At the beginning, I gave myself a name that made Chinese feel tongue-twisting.

"I said, Old Gu, we have to do it together, can't you finish the work, the boss will fire us, right?" Zhao Bingbiao saw that Guderian was having trouble speaking, so he didn't bother to go around in circles and directly put forward his own requirements to him.

When Guderian heard Zhao Bingbiao's words, he looked at this guy who was about his age suspiciously.

"Day ......" Zhao Bingbiao was depressed, feeling that he was a waste of expression.

"How the fuck are you going to live after that?" Zhao Bingbiao cursed in his heart, but pointed at Guderian himself. Then he pointed to Guderian, and then to the grinding machine that had only removed a fifth of the rails.

Guderian saw Zhao Bingbiao's gesture, understood what this guy meant, and nodded at Zhao Binbiao. He put the teacup in his hand on the tool cabinet not far away, and then touched Zhao Bingbiao with his hand, motioning him to go up to the top of the machine tool with him.

The working part of the rail grinder was too heavy, and although there were cranes, the Soviets were not very familiar with these modified cranes in China. The original mechanic of this factory will be more reliable than what he did.

The two of them hurt the machine tool along the ladder, and after Guderian gestured for a while, Zhao Bingbiao understood. It was he who beckoned the Chinese workers of the factory to drive and lift the working part above.

Thanks to the joint efforts of the workers of China and the Soviet Union, the dismantling work began to be made faster.

It turned out that Zhao Bingbiao and the others needed at least a week to complete the disassembly of those various parts, but now it only took more than three days to disassemble this huge guide rail grinder. Upper surface of the guide rail grinding machine. The most difficult thing to disassemble and assemble is the working part above. This guide rail grinder from the Soviet Union uses a hydraulic system in the working part, and the workbench below is not like an ordinary surface grinder that uses electromagnetic principles to magnetically adsorb the workpiece on the workbench. Instead, the huge bed guide rail part of the machine tool is pressed on the top of the workbench with an ordinary pressure plate, and it is fastened by threads.

As soon as the workbench is removed, the part of the guide rail underneath the workbench is revealed.

Rail grinding machines are heavy-duty machine tools, and they don't want to use electromagnetic principles to raise the table without those small-surface grinding machines and cylindrical grinding machines.

The huge guide rail grinder from the Soviet Union in the 9327 factory is a gantry type, that is, there is a guide rail on each side of the workbench, and the working parts of the grinder are mounted on the high-precision tracks on both sides. When working, the workpiece does not do any movement, because the most ordinary machine tool bed on the guide rail grinding machine has to weigh more than one ton, and the heavy-duty machine tool bed will even exceed ten tons, which is the technology of the fifties, and the application of electromagnetic principles is far less mature than decades later. Therefore, the workbench cannot be moved, only the working parts are moved.

Because the working parts are more than one ton, the guide rail of this guide rail grinder is used for a long time, and there is no floating device installed under the column on both sides, and the V-shaped groove below the column is in contact with the V-shaped guide rail and the plane guide rail on the grinding machine, although the hardness of quenching is very high, but the long-term friction will still cause the wear of the guide rail.

If the wear degree of the guide rails on both sides is the same, it will not affect the machining accuracy. If the wear on both sides is inconsistent, the upper part of the work will be unbalanced, which will affect the accuracy of machining.

The so-called machine tool overhaul, the most important thing is to repair the guide rail.

For machine tools with low precision requirements, the guide rail can be finished by using a guide rail grinder to achieve the design accuracy requirements. But equipment such as guide rail grinders, as well as those used for super precision machining, all the guide rails will be polished by hand after the precision grinder is finely ground.

The main purpose of the Soviet mechanics and the fitters left over from the original factory under Zhao Bingbiao was to use special files to refine the guide rails of these heavy finishing equipment used to machine tool guides and spindle holes. After they refine, they must ensure the accuracy of this guide rail.

Using the principle of light projection, the straightness of the 10-meter-long guide rail is guaranteed to be within 0.01mm. At the same time, it is also necessary to ensure that the parallelism and flatness of the two parallel guide rails are within 0.02mm.

It can be said that the matter of refining the guide rail is the most important work of the ninth-level fitter, and at the same time, it is also the most ultimate work of the ninth-level fitter.

These machines are dismantled to only the bed with guide rails, and even after the guide rails are refined, it will take some time before assembly can begin.

The purpose of Yunfei is not only to carry out the overhaul of these machine tools.

If that were all he had, he wouldn't need to bring those Soviet engineers to the base deep in the mountains. The purpose of bringing these Soviet engineers was to carry out the technical transformation of these old machine tools. He couldn't even think about changing these equipment to numerical control equipment. At least, he didn't have to think about it until there was a high-precision ball screw that was more than ten meters long.

These devices, not only in the way they are controlled, are the techniques of the forties and fifties, but also in the electrical equipment.

Yun has to transform these devices into digital display machine tools. In this way, in the processing process, the quality control of the product is easier than before, and the worker only needs to look at the number on the digital display device to enter or retreat.

Digital display control device, for Huadu CNC, this is the simplest thing. This does not require an industrial control chip, only needs to add a position detection device, plus the ability to display the relative displacement or absolute displacement data of moving parts.

It was also very easy for the Soviet engineers of the nineties to complete the technical transformation that they had begun to perfect since the eighties.

Therefore, the main work of dozens of fitters is to disassemble these machine tools, re-measure some worn parts, and make new ones to replace the worn parts of these machine tools.

There are also eighth-level lathes in the 9327 factory, but there are only two of them. One of them is fifty-five years old, and before Yun Fei took over, he had already gone through the internal retirement procedures and returned to his hometown in the northeast to retire. The remaining one is also past the age of fifty, and now the energy is simply not able to catch up with the thirty-four years old in the prime of life. Although the experience of the old mechanic is quite important, the experience, especially in the technical industry, many things can only be understood but cannot be spoken.

Just like some lathes, without any reference, when the workpiece is clamped with a four-jaw chuck, the workpiece can be found within 0.1mm by the naked eye and the force when turning the chuck. The average person's hair is only about 0.06mm in thin and 0.1mm in thickness. That is to say, when the workpiece is rotating, those experienced masters can make the workpiece beat only a little bit of human hair in the process of rotation by looking at it with the naked eye.

It is not easy to find large workpieces, especially rotary heavy parts processed on heavy horizontal lathes. The machining of many parts, even the alignment of the workpiece, takes a day or two, but the machining process is only half the time.

These things can be called stunts in the machinery industry. But there are very few people who can practice.

There is a saying that is widely circulated throughout the machinery industry - the master leads the door, and the practice is in the individual.

In other words, many things are not taught by the master, but taught by the master, and the apprentice cannot be able to understand them. Almost every top worker, such as a level 9 fitter, level 8 turner, who of these workers has not been able to have a unique job? (To be continued......)
