Smart Industrial Empire

Guderian and others from the Soviet Union signed contracts with Kamat at least ten years or more.

Therefore, many people learn Chinese with an interpreter on the train. Unfortunately, Chinese is too difficult. After more than 20 days of practice, their tongues are numb. Except for those who are relatively young and can barely communicate with each other, People in their 50s and [-]s can only learn some of the simplest common words, so just saying these few words made Guderian's face flush.

Even the assembly and disassembly of the most compact crankshaft grinder in the entire Soviet Union is not as difficult as this.

"My name is Zhao Binbiao, and I'm the master fitter here." Zhao Binbiao stretched out his hand to Guderian, and introduced himself to the Soviet man. This guy will be his partner in the future.In order not to argue with each other in future work, they, the leaders of China and the Soviet Union, must reach an agreement.

Otherwise, in the future work, if the progress is delayed or something, let alone whether they will be severely punished, at least the bonus will be much less.The salary system in the new factory has come out. In addition to the basic salary in the factory, what they get the most will be bonuses.How do you get the bonus?Not only to assess how much work each person has done, but also to assess the entire team.The assessment of the team occupies 60.00% of the entire bonus.

In other words, if a team has a problem with one person, everyone can only get 40.00% of the bonus.This is related to the future income of people like themselves.

"Zhao..." Guderian also stretched out his hand, and his two rough hands were tightly held together.However, the pronunciation of Zhao Bingbiao's name was too difficult for Guderian. He only said Guderian's last name, and his face was flushed, but he couldn't pronounce the word Bingbiao.

As for Guderian being able to tell his last name, Zhao Bingbiao felt that even if the big Soviet brother in front of him couldn't remember his name, he was no wonder.If you want to blame, you can only blame your parents.At the beginning, I gave myself a name that made Chinese people feel tongue-twisting.

"I said, Old Gu, we have to work together. Can't you finish the work and the boss fire us?" Zhao Bingbiao saw that Guderian was having a hard time speaking, so he didn't bother to go around in circles, and directly made his request to him .

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

"Day..." Zhao Bingbiao was depressed, his feelings are a waste of expression.

"How will you live this fucking life in the future?" Zhao Bingbiao cursed inwardly, but pointed at Guderian.Then he pointed to Guderian, and then pointed to the guide rail grinder that had only been dismantled by one-fifth.

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

The working part of the rail grinding machine is too heavy. Although there are cranes, the Soviets are not very familiar with these modified cranes in China.It would be more reliable for the factory's original technician to direct the driving than him.

The two of them hurt the machine tool along the ladder. After Guderian gestured for a while, Zhao Bingbiao understood.It is to ask him to call the Chinese workers in the factory to drive the car and hang the working part on it.

With the joint efforts of workers from China and the Soviet Union, the dismantling work began to become faster.

It turned out that Zhao Bingbiao and the others needed at least a week to complete the disassembly of the various parts, but now it took only more than three days to disassemble this huge guide rail grinder.Above the rail grinder.The most difficult disassembly and assembly is the above working part.This guideway grinding machine from the Soviet Union uses a hydraulic system for the working part. The workbench below does not use electromagnetic principles to magnetically adsorb the workpiece to the workbench like ordinary surface grinders.Instead, ordinary pressure plates are used to press the huge bed guide rails of those machine tools on the workbench, and they are fastened by threads.

Once the workbench is removed, the guide rail part under the workbench is exposed.

The guide rail grinding machine is a heavy-duty machine tool equipment. Unlike those small surface grinders and cylindrical grinders, the electromagnetic principle is used to raise the worktable.

The 9327 Factory’s huge guide rail grinding machine from the Soviet Union is of the gantry type, that is, there is a guide rail on each side of the workbench, and the working parts for the grinder are installed on the high-precision rails on both sides.When working, the workpiece does not make any movement, because the most common machine bed on the guide rail grinding machine weighs more than one ton, and the heavy machine bed can even exceed ten tons. It is the technology of the 50s and uses electromagnetic principles. Applications are far from mature after decades.Therefore, the workbench cannot be moved, only the working parts are moved.

Since the working parts weigh more than one ton, the guide rail of this guide rail grinder has been used for a long time, and there is no floating device installed under the columns on both sides. The two surfaces of the guide rail and the plane guide rail are in contact. Although the hardness of the quenching is very high, long-term friction will still cause the wear of the guide rail.

If the wear degree of the guide rails on both sides is consistent, it will not affect the machining accuracy.If the wear on both sides is inconsistent, it will make the upper working part unbalanced, thus affecting the machining accuracy.

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

The precision requirements are not particularly high for machine tools, and the guide rails can meet the design precision requirements after finishing with a guide rail grinder.However, for equipment such as guide rail grinding machines, as well as those equipment used for super precision machining, all guide rails will be manually ground after precision grinding on the precision grinder.

The main purpose of the Soviet technicians and the fitters left by the original factory under Zhao Bingbiao is to use special files to refine the guide rails of these heavy-duty finishing equipment used to process machine tool guide rails and spindle holes.After they are refined, they must ensure the accuracy of the guide rail.

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

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

After these machine tools are dismantled to only the bed with guide rails, even after the guide rails are refined, it will take a while to start assembly.

The purpose of Yunfei is not just to overhaul these machine tools.

If that's all, he doesn't need to bring those Soviet engineers to the base deep in the mountains.The purpose of bringing these Soviet engineers is to carry out the technical transformation of these old machine tools.He didn't even dare to think about changing these devices into numerical control devices.At least, he didn't think about it until there was no high-precision ball screw with a length of more than ten meters.

These devices, not only the control method, is the technology used in the 50s, but also the electrical equipment.

Yunfei wants to transform these devices into machine tools with digital displays.In this way, in the process of processing, the quality control of the product is easier than before. Workers only need to look at the numbers on the digital display device to perform the operation of feeding or returning.

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

For the Soviet engineers in the 90s, it was also very easy to complete the technical transformation that they had begun to perfect in the 80s.

Therefore, the most important job of dozens of fitters is to disassemble these machine tools, remeasure some worn parts, and make new ones to replace the worn parts of these machine tools.

There are eighth-level lathe workers in the 9327 factory, but there are only two of them.One of them is 55 years old. Before Yunfei took over, he had gone through the internal retirement procedures and returned to his hometown in Northeast China for the elderly.The remaining one is also over 50 years old, and now the energy is simply unable to catch up with the 34-year-old man.Although the experience of veteran technicians is very important, experience is something that, especially in the technology industry, many things can only be understood and cannot be expressed in words.

Just like some lathe workers, without any reference, when using a four-jaw chuck to clamp the workpiece, the workpiece can be found within 0.1mm by the naked eye and the degree of force when turning the chuck.The average person's hair is only about 0.06mm for thinner hair, and only about 0.1mm for thicker hair.That is to say, when the workpiece is rotating, those experienced master craftsmen can see with the naked eye that the beating of the workpiece during the rotation is only as small as a human hair.

It is very difficult to find large workpieces, especially rotary heavy parts processed on heavy horizontal lathes.It would take a day or two to machine many parts, even to align the workpiece, but the machining process takes half that time.

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

There is a widely circulated saying in the entire machinery industry-the master leads the door, and the practice depends on the individual.

In other words, it is not that the master does not teach many things, but that if the master teaches, it is impossible for the apprentice to understand.Almost every top worker, such as a ninth-level fitter and an eighth-level lathe worker, who among these workers can't have a unique skill?
