After Zhang Yi and his colleagues Qicaishi Machinery Factory successfully developed a high-precision bearing production line, even the Xian County government held a special meeting for this purpose.

After all, this is the first time in China that an ultra-high-precision bearing has been successfully developed by itself, and the manufacturer that developed this production line is from their county. This is definitely a full political achievement for the leaders of the county.

Even after the county government meeting was held, many people did not leave. Instead, they smoked cigarettes and chatted. The content of the chat was naturally about their Qicai Stone Machinery Factory.

"Zhang Ming's son is really amazing. Even the large state-owned manufacturers in China have not successfully shipped such a production line. In other words, the production lines they have shipped are far inferior to this in terms of precision.

For the bearings produced by their production line, you must know that it has only been a few months since their factory started developing this production line.'

"Who says it's not the case? When I just got the news from the director of the development zone office last night, I thought it was a rumor. I didn't expect it to be true. The production line has been successfully run for the first time. It's amazing.

"

"Now I really envy Zhang Ming for having such a son. When the Qicai Stone Machinery Factory was in Zhang Ming's own hands, it was still half-dead, but after it was in the hands of his son Zhang Yi, in less than half a year, it became

With the current scale, my brat can't be seen all day long, and I don't know where he is fooling around. If he could be half as good as Zhang Ming's son, I would be satisfied."

Colorful Stone Machinery Factory.

After the first successful operation of the production line, the production line should have been dismantled to evaluate the condition of the production line after the first operation. However, due to the late time of the day and the fact that everyone went out to celebrate that night, it was not until the next morning

, this production line was dismantled.

It took a whole day for many top students in the factory to dismantle all the important parts of this production line.

And carefully checked the wear status of these important parts of the production line to see if there are any problems after the first operation.

After all, a huge production line, no matter how good the designer is, cannot be perfect. After operation, there will be some problems.

But the key point is, no matter what the problem is, it is not serious. What impact will it have on the production of the entire production line? Is it necessary to make some modifications to the original design?

Trial run? It is originally used to test the operation of the production line, as well as comprehensive factors such as manufacturing, assembly, and materials.

Of course, the dismantling of the production line only involves dismantling some important parts. It is impossible to dismantle the entire huge production line. Otherwise, even if it takes ten days and a half, it will not be completed.

.

After all, the production line is a huge whole, which contains not only small high-precision parts, but also oversized and heavy-duty accessories. It is impossible to dismantle and inspect parts like these.

After dismantling the key parts of the production line, these top students began to check the damage of these accessories.

At the same time, Zhang Yi did not go out on this day, but worked with these top students to carefully clean and inspect the disassembled accessories.

To check these accessories, the first thing to do is to carefully clean these accessories with gasoline, etc. After cleaning, carefully inspect these accessories one by one.

When inspecting, the first thing to check is the appearance of these accessories and whether they are deformed or damaged.

Their Qicaishi Machinery Factory had built a production line before. Although it was only a production line for aerodynamic bicycles, Zhang Yi and the others emphatically checked the bearings on the production line after learning from the past.

At the same time, this is a large-scale high-precision bearing production line. Therefore, many key parts of this production line rotate very fast and have high requirements for bearing performance. Therefore, the bearings on these parts must be inspected most carefully.

Even during the inspection, Zhang Yi and the others put on white gloves and used magnifying glasses to inspect every groove on the bearing, every steel ball, and every small detail.

The entire production line has not been dismantled, but just these key parts have a lot of disassembled parts, and the time required to inspect these parts will also take several days.

This is even if no problems are found or there are not many problems. If more problems are found, it will take longer, even ten days and a half.

Zhang Yi held the bearing in his hand and inspected it carefully in front of the inspection table. From time to time, he picked up a small flashlight and some testing instruments to inspect the bearing in his hand. At the same time, he frowned.

"Master Jiang, come here, there seems to be a problem with this bearing." Since this period of time, Zhang Yi has been actively learning various mechanical knowledge from these top students in the factory, so now his vision and level have improved.

It has improved a lot, but he couldn't judge the high-precision bearing in his hand for the moment, so he said to Jiang Shuai next to him.

As the design and R&D chief engineer of this production line, Jiang Sui is also very conscientious. He goes to the workshop before dawn every morning, and is still in the workshop at 11 or 12 o'clock in the evening, and sometimes even

He even eats and sleeps in the workshop.

After listening to Zhang Yi's words, Jiang Shuai immediately came over, picked up the bearing in Zhang Yi's hand and inspected it carefully.

Soon Jiang Shuai also discovered that there was indeed something wrong with this bearing, because the color of one place in the bearing was obviously much brighter than other places.

"Boss, this bearing is obviously no longer usable. This part should be the fastest running place on the production line, so a bearing like this cannot withstand such high-speed operation.

If my guess is correct, there must be problems with the bearings in several other high-speed operation areas on this production line.

But fortunately, we have anticipated such a situation, and during the trial operation of the production line, we gave priority to producing this type of bearing." After inspection, Jiang Shuai said to Zhang Yi.

Then Zhang Yi and Jiang Shuai inspected other high-speed running parts on the production line. Sure enough, just as Jiang Shuai said, there were more or less problems with the bearings in these high-speed running parts.

It's just that it's not as serious as the one I checked before. Judging from the situation, even in these parts, the bearings on them won't last long. After all, the speeds of these high-speed running parts have reached tens of thousands of rpm. This is simply not possible.
