Chapter 159

Goodrian and others from the Soviet Union signed contracts with camart for at least ten years.

Therefore, many people learn Chinese from translators on the train. Unfortunately, Chinese is too difficult. They practice it for more than 20 days, and their tongues are numb. Except for those young people who can barely communicate with each other, they can only learn some of the simplest common words in their 40s and 50s, Goodrian blushed.

Even assembling and disassembling the most compact crankshaft grinder in the whole Soviet Union was not as difficult as this.

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

Otherwise, if the work in the future is delayed or something, let alone whether it 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, the most part they get is the bonus. How do you get the bonus? Not only how much work each person has done, but also the whole team. The assessment of the team accounts for 60% of the whole bonus.

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

"Zhao..." goodrian also stretched out his hand, and two pairs of rough big hands held tightly together. However, the pronunciation of Zhao bingbiao's name is too difficult for goodrian. He only said goodrian's last name. His face was red and there was no way to pronounce bingbiao.

As for goodrian's ability to say his last name, Zhao bingbiao felt that even if the big brother of the Soviet Union could not remember his name, it was no wonder that he. You can only blame your parents. At the beginning, you gave yourself a name that makes Chinese people feel tongue twister.

"I said, Lao Gu, we have to work together. You can't finish the work. Did the boss leave us?" Zhao bingbiao saw that goodrian spoke hard, so he didn't bother to circle and put forward his own requirements directly to him.

When goodrian heard Zhao bingbiao's words, he looked at this guy who was about his age in doubt.

"Day..." Zhao bingbiao was depressed and felt that it was a waste of expression.

"How to live in the future." Zhao bingbiao scolded secretly in his heart, but pointed to Guderian, then pointed to Guderian, and then pointed to the guide rail grinder that had only been removed one-fifth.

Goodrian saw Zhao bingbiao's gesture, understood the meaning of this guy, and nodded to Zhao binbiao. Put the tea cup in his hand on the tool cabinet not far away, then touched Zhao bingbiao with his hand and motioned him to go up to the top of the machine tool with himself.

The working part of the guide rail grinder is too heavy. Although there are traveling cranes, the Soviets are not very familiar with the modified traveling cranes in China. It would be more reliable for the original technicians of this factory to command the traveling cranes.

The two injured the machine tool along the ladder. After goodrian gestured for a while, Zhao bingbiao understood that he asked the Chinese workers in the factory to drive and hoist the working part down.

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

It used to take Zhao bingbiao at least a week to complete the disassembly of those components. Now it took only more than three days to disassemble this huge guide rail grinder. On the guide rail grinder, the most difficult to disassemble and assemble is the working part above. The working part of this guide rail grinder from the Soviet Union uses the hydraulic system. The worktable below does not use the electromagnetic principle to adsorb the workpiece on the worktable with magnetic force like the ordinary surface grinder, but uses the ordinary pressing plate to press the huge bed guide rail part of those machine tools on the worktable and fasten it by threads.

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

Guideway Grinder belongs to heavy machine tool equipment. It doesn't want those small plane grinder and cylindrical grinder to use electromagnetic principle to raise the worktable.

The huge guide rail grinder from the Soviet Union in 9327 factory is gantry type, that is, there is a guide rail on both sides of the workbench, and the working parts of the grinder are installed on the high-precision tracks on both sides. When working, the workpiece does not make any movement, because the most common machine tool bed on the guide rail grinder also needs more than one ton, and the heavy machine tool bed will even exceed ten tons. It is a technology in the 1950s, and the application of electromagnetic principle is far from mature in decades. 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 has been used for a long time. In addition, there is no floating device under the columns on both sides. The V-shaped groove under the column is in contact with the V-shaped guide rail and plane guide rail on the grinder. Although the quenching hardness is very high, the long-term friction will still cause the wear of the guide rail.

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

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 meet the precision requirements of the design after finishing with the guide rail grinder. However, for equipment such as Guideway Grinder and those used for super precision machining, all guideways will be grinded manually after fine grinding by precision grinder.

The main purpose of Soviet technicians and the fitters left by Zhao bingbiao's original factory is to refine the guide rails of these heavy finishing equipment used to process machine tool guide rails and spindle holes with special files. After finishing, they must ensure the accuracy of the guide rail.

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 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 finishing of guide rail is the most important work of level 9 fitter, and it is also the most ultimate work of level 9 fitter.

After these machine tools are disassembled so that only the bed with guide rail is left, even after the guide rail is refined, it will take some time to start assembly.

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

If only that, he would not 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 dare to think about changing these equipment into CNC equipment. At least, he won't think about it until there is a high-precision ball screw with a length of more than 10 meters.

These equipment, not only the control mode, is the technology used in the 1940s and 1950s, and the same is true for electrical equipment.

The cloud has to transform these devices into digital display machine tools. In this way, in the processing process, the quality control of products is easier than before. Workers only need to look at the numbers on the digital display device to feed or retreat.

Digital display control device is the simplest thing for Huadu CNC. This does not need an industrial control chip. It only needs to add a position detection device and be able to display the relative displacement or absolute displacement data of the moving parts.

It was also very easy for Soviet engineers in the 1990s to complete the technical transformation that had begun to become 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 Grade 8 lathe workers in 9327 factory, but there are only two. 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 the northeast to provide for the elderly. The remaining one is over the age of 50, and now his energy can't catch up with the age of 34. Although the experience of old technicians is very important, experience, especially in the technology industry, is something that can only be understood and can not be expressed.

Just like some lathe workers, when clamping the workpiece with a four jaw chuck without any reference, they can find the workpiece within 0.1mm with the naked eye and the force when rotating the chuck. For ordinary people's hair, the thinner one is only about 0.06mm, and the thicker one is only about 0.1mm. In other words, when the workpiece is rotating, those experienced teachers can make the beating of the workpiece in the process of rotation only a little bit like human hair with the naked eye.

It is not easy to find large workpieces, especially the rotary heavy parts processed on the heavy horizontal lathe. It takes a day or two to process many parts and even find the right workpiece, but the processing process takes only half of 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 widely spread throughout the machinery industry that the master leads the door and the practice is personal.

In other words, many things are not what the master doesn't teach, but what the master teaches, and the apprentice can't understand. Almost every top worker, such as level 9 fitter and level 8 lathe worker, who can't have a unique skill?
