In the following days, Wang Bin was busy acquiring this Tianyuan Optical Co., Ltd.

At the same time, with the help of Qin Meiyu in recent days, Wang Bin also acquired a small special steel smelting enterprise in the city.

However, the scale of this special steel smelting enterprise is not very large, and its production line production scale is only two or three hundred tons per day, but this is temporarily enough for their Tiangong Technology.

With the successful acquisition of the two companies, Wang Bin did not make any adjustments to the personnel of these two companies except for some financial adjustments. Even Wang Bin, the heads of these two companies, kept them.

After all, if Cai Yuanxin and others are able to do this level from a small business, it means that their abilities are absolutely excellent.

After arranging all the affairs of these two companies, Wang Bin returned to his Tiangong Technology.

After all, Wang Bin knew very well that compared to other things, the two factories at the headquarters are the foundation of their Tiangong Technology.

However, when Wang Bin returned to their new factory, the ultra-high-precision CNC machine tools and ultra-high-precision bearing production lines in the new factory have been installed and can be produced at any time.

After Wang Bin came back, he immediately arranged personnel to start producing ultra-high precision bearings.

With a bearing sleeve blank with a diameter of about two meters, under the operation of the master, it was slowly lifted to the workbench of the large ultra-high precision CNC machine tool by the lifting equipment in the factory. After all, such a large bearing sleeve is not small, and it has a weight of more than one ton. If you do not use the mobile hanging table in the factory, it is not easy to move the bearing sleeve to the workbench of the machine tool.

Then, the bearing sleeve was tightly clamped by the fixture on the workbench, and the protective cover of the machine tool was slowly closed. Master Zhou and Wang Bin, who were operating the machine tool, also stared at the situation in the mainland of the machine tool.

At this time, the machine tool has already started to process this bearing sleeve under the action of the CNC program, although the diameter of this bearing sleeve is relatively large.

However, the required precision is not low, so the price is not small, and the time required is not enough to be solved in a few minutes. It is impossible to complete such a bearing sleeve without a few hours.

At the same time, there are also high technical requirements for machine tool operators. Fortunately, this super high-precision CNC machine tool master from Tiangong Technology was found by Wang Bin for Qin Meiyu to help him. This name is Master Zhou Fangwei, and he is absolutely competent in technology.

Metal fragments in the machine tool splashed everywhere, and the machine tool was running at an even speed and smooth pace. In the eyes of Wang Bin and others, more than two hours passed quickly. At this time, the machine tool also began to withdraw its tool, which proves that the processing of the bearing sleeve is about to be completed.

Wang Bin and others were also a little excited. After all, this is a bearing sleeve processed from an ultra-high precision CNC machine tool!

The turning tool of the machine tool slowly retreated in the eyes of Wang Bin and others, and the operation of various components of the machine tool began to stop. The safety door of the machine tool was slowly opened. The processed bearing sleeve finally appeared in front of Wang Bin and others.

So Wang Bin and Master Zhou immediately took the high-precision measuring instrument and went up to measure the bearing sleeve. At the same time, whether it is good or bad, you can see the true meaning immediately.

Therefore, both Master Zhou and Wang Bin looked a little nervous. Although in the mechanical processing industry, failures in parts processing are often happening, and even no matter how precise and automated the equipment is, it is possible to fail.

However, Wang Bin, Master Zhou and others did not hope that Tiangong Technology would fail to use ultra-high precision CNC machine tools to process this bearing sleeve for the first time.

When I saw this bearing sleeve that had just been processed, my first reaction was that it was very beautiful, it looked very bright, without any burrs. When I touched it with my hands, it seemed like I was touching the surface of a glass mirror, and it felt very smooth. Wang Bin had already had some confidence in this bearing sleeve.

After all, this is a bearing sleeve processed using ultra-high precision CNC machine tools!

According to the requirements of 969 Group, the precision level of this bearing sleeve is actually enough as long as the accuracy of p3 level is reached. Wang Bin has a premonition that the accuracy of this bearing sleeve processed by ultra-high precision CNC machine tools will definitely exceed the level required by 969 Group.

Just as Wang Bin was looking at the bearing sleeve, Master Zhou, who was standing beside him, had already started to measure the bearing sleeve. During the measurement process, Master Zhou nodded from time to time, and his face was filled with joy.

"Mr. Zhou! How is the situation?" Seeing Master Zhou's expression, Wang Bin had already expected it, but he not only asked.

"Mr. Wang! The accuracy of this bearing sleeve is beyond my expectations. According to my experience, the accuracy of this bearing sleeve can reach level three at most, which is already very good. Although this machine tool is an ultra-high precision CNC machine tool.

But no matter what, this is a new equipment and it still needs to be run-in. I didn’t expect that our country will make such great progress in machine tools. It’s amazing that we can reach this level without running-in. If we do a certain running-in, the accuracy will definitely be improved again.

At the same time, it is impossible to be in place at once in terms of data adjustment, but according to my measurement, the precision level of this bearing sleeve has actually reached the level of second level.

In other words, if we make certain adjustments to the machine tool, it is not impossible to achieve the level of first-level accuracy." Master Zhou said.

"What, the accuracy of this bearing sleeve has reached the second level of accuracy?" Wang Bin said curiously. To be honest, he could not have imagined that this accuracy could be achieved.

However, Wang Bin did not agree with what Master Zhou said about improving the precision level, because if we follow the requirements of 969 Group, it would be enough to meet the third-level standard. Now we have reached the second-level accuracy, which has far exceeded the requirements of 969 Group.

So what we need to do now is to increase the processing speed. After all, the processing time of a few hours is too slow for this bearing. If another bearing sleeve is added to this bearing, Wang Bin calculated that in one day, their Tiangong Technology could not process such a set of bearings. How could Wang Bin tolerate it?

What's more, with such processing speed, you don't have to think about completing the bearing order for 969 Group within one month.

After all, even if you can process one set a day, you can only process up to thirty sets of such bearings in a month.
Chapter completed!
