Intelligent Industrial Empire

Guderian and others from the Soviet Union signed a contract with Kamath for the shortest period of more than ten years.

Therefore, many people follow the interpreter to learn Chinese on the train. Unfortunately, Chinese is too difficult. After more than 20 days of training, the tongue is tingling, except for those younger ones who can barely carry out the simplest basic communication. , These people in their forties and fifties can only learn the simplest common words, so just saying these words makes Guderian blush.

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 am the master fitter here." Zhao Binbiao stretched out his hand to Guderian and introduced himself to the Soviet man, who will be his partner in the future.In order not to wrestle with each other in future work, they, the leaders of China and the Soviet Union, must reach an agreement.

Otherwise, the work will delay the progress or something in the future, not to mention whether you will be severely punished, at least the bonus will be much less.The wage system in the new factory has come out. After the factory, in addition to the basic salary, they will get the most part of the bonus.How come the bonus?Not only does it evaluate how much work each person has done, but also the entire team.The assessment of the team occupies 60% of the total bonus.

In other words, if a team, as long as one person has a problem, each person can only get 40% of the bonus.This can be related to the future income of people like yourself.

"Zhao..." Guderian also stretched out his hands, and the two big 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 red and there was no way to pronounce the word Bingbiao.

Zhao Bingbiao felt that Guderian was able to say his surname, even if the Soviet eldest brother in front of him could not remember his name, he could not be blamed.I can only blame my parents, who gave me a name that made Chinese people feel confusing.

"I said, Lao Gu, we have to work together, can't you finish the work, the boss opened us?" Zhao Bingbiao saw that Guderian had a hard time talking, so he didn't bother to go around the circle and directly put forward his own ideas to him. Claim.

Guderian heard Zhao Bingbiao's words and looked at this guy who was about his age in confusion.

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

"How do you live these fucking days?" Zhao Bingbiao cursed secretly in his heart, but he pointed to Guderian, then pointed to Guderian, and then pointed to that station before removing half of it. A guide rail grinder.

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

The work part of the rail grinder is too heavy. Although there are driving vehicles, the Soviets are not very familiar with these modified driving vehicles in China. The original mechanics of this factory will direct the driving and it will be more reliable than him.

The two injured the machine tool along the ladder. After Guderian made gestures for a while, Zhao Bingbiao realized that he was asking the Chinese workers in the factory to drive and hoist the working part.

With the joint efforts of Chinese and Soviet workers, the demolition work began to become faster.

It turned out that it took Zhao Bingbiao at least one week to complete the disassembly of the various parts. Now it took only more than three days to disassemble this huge rail grinder.The most difficult part to disassemble and assemble on the rail grinder is the upper working part.This guide rail grinder from the Soviet Union uses a hydraulic system for its working part. The workbench below does not use electromagnetic principles to magnetically attract the workpiece to the workbench like an ordinary surface grinder, but uses an ordinary pressure plate to hold the huge machine tools. The guide rail of the bed is pressed on the worktable and fastened by threads.

As soon as the workbench is removed, the guide rail under the workbench is exposed.

Guide rail grinders are heavy-duty machine tools. I don't want those small surface grinders and cylindrical grinders, but use electromagnetic principles to raise the workbench.

This huge rail grinder from the Soviet Union of 9327 Factory is a gantry type, that is, there is a rail on each side of the worktable, and the working parts of 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 this rail grinder also has to be more than one ton, and the heavy machine bed can even exceed ten tons. It is a technology in the 1950s, electromagnetic principle The application is far from mature in decades.Therefore, the workbench cannot be moved, only the working parts are moved.

Because the working parts are all over one ton, the guide rail of this guide rail grinder has been used for a long time, and there is no floating device under the columns on both sides. The V-shaped groove under the column and the V-shaped on the surface of the grinder The two surfaces of the guide rail and the flat guide rail are in contact, although the quenching hardness is very high, but 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 two sides wear inconsistent, it will make the upper working part unbalanced, thus affecting the accuracy of processing.

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

For machine tools with not particularly high precision requirements, the guide rails can meet the design precision requirements after they are finished by a guide rail grinder.But for equipment such as rail grinders and those used for super precision machining, all rails will be manually ground after the precision grinding.

The main purpose of the Soviet mechanics and the fitters left by the original factory under Zhao Bingbiao's main purpose is to use special files to refine the guide rails of these heavy finishing equipment used to process machine tool guides and spindle holes.They must ensure the accuracy of this guide rail after finishing.

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

It can be said that fine-tuning the guide rail is the most important job of the Level 9 fitter, and at the same time, it is also the most ultimate job of the Level 9 fitter.

After these machine tools are dismantled so that only the bed with guide rails are left, even after the guide rails are finished, it will take some time to start assembly.

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

If it was just that, he wouldn't need to bring those Soviet engineers to the base deep in the mountains.The purpose he brought these Soviet engineers was to carry out the technical transformation of these old machine tools.He couldn't even think about changing these equipments into numerically controlled equipment.At least, he shouldn't think about this until there is no high-precision ball screw with a length of more than ten meters.

These devices are not only controlled by the technology used in the 1940s and 1950s, but also for electrical equipment.

Yun has to transform these equipment into digital display machine tools.In this way, in the processing process, the quality control of the product is easier than before. The workers only need to look at the numbers on the digital display device to perform the operation of cutting in or retracting.

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

For the Soviet engineers in the 1990s, it was very easy to complete the technological transformation that they had begun to perfect in the 1980s.

Therefore, the most important 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 eight level lathe workers in the 9327 factory, but there are only two.One of them was 55 years old, had gone through internal retirement procedures before Yunfei took over, and returned to his hometown in the Northeast.The remaining one is already over fifty years old, and now his energy simply can't keep up with the thirty-four-year-old man.Although the experience of veteran technicians is very important, but experience, especially in the technology industry, many things are things that can only be expected and cannot be explained.

Just like some lathes, without any reference, when clamping a workpiece with a four-jaw chuck, they can locate the workpiece within 0.1mm with the naked eye and the force when turning the chuck.The average person’s hair is only about 0.06 mm thinner and about 0.1 mm thick.That is to say, when the workpiece is rotating, those experienced masters can see with the naked eye, so that the beating of the workpiece during the rotation is only as small as a human hair.

It is not easy to find large workpieces, especially heavy-duty rotary parts processed on a heavy-duty horizontal lathe.The processing of many parts and even the alignment of the workpiece will take a day or two, but the processing time is only half of the time.

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

There is a word widely circulated throughout the machinery industry-the master leads the door, and the practice is personal.

In other words, many things are not taught by the master, but by the master, and the apprentice cannot understand it. Almost every top-level worker, such as the 9th-level fitter and the 8th-level turner, who hasn't been able to master the skills?
