In the next few days, Wang Bin has been busy with the acquisition of Tianyuan Optical Co., Ltd.

At the same time, in the past few days, with the help of Qin Meiyu, Wang Bin also bought a small special steel smelting enterprise in Tiangong Technology in the city.

It's just that the scale of this special steel smelting enterprise is not very large, and the production scale of its production line is only two to three hundred tons per day, but this is temporarily enough for Tiangong Technology.

With the successful acquisition of the two companies, Wang Bin made no adjustments to the personnel of the two companies except for some financial adjustments. Even the heads of the two companies, Wang Bin, All left them.

After all, if Cai Yuanxin and others are able to take their business from a small business to this level, it means that their ability is absolutely leveraged.

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

Wang Bin knew very well that, compared to others, the two factories at the headquarters were 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 had been installed in the new factory, ready for production at any time.

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

With a bearing sleeve blank with a diameter of nearly two meters, under the operation of the master, it was slowly hoisted to the workbench of the large ultra-high precision CNC machine tool by the lifting equipment in the workshop. After all, such a large bearing The weight of the sleeve is not small. With such a weight of more than one ton, it is not easy to move the bearing sleeve to the workbench of the machine tool without using the mobile crane in the factory building.

Afterwards, the bearing sleeve was tightly clamped by the fixture on the workbench, and then the protective cover of the machine tool was slowly closed, and Master Zhou and Wang Bin who operated the machine tool also kept their eyes on the inside of the machine tool. Happening.

At this time, the machine tool has already begun to process the bearing sleeve under the action of the numerical control program.

This bearing sleeve has a relatively large diameter. But the precision required is not low, so the price is not small, and the difficulty is not small, and the time required cannot be solved in a few minutes. It is impossible to process such a bearing sleeve without a few hours. Finish.

At the same time, in terms of machine tool operators, there are also high technical requirements. Fortunately, Wang Bin spent a lot of money to ask Qin Meiyu to help find this ultra-high-precision CNC machine tool master of Tiangong Technology. The master's name is Zhou Fangwei. Absolutely up to the task.

Metal fragments in the machine tool were flying everywhere, and the machine tool had been running at a constant speed. Under the eyes of Wang Bin and others, more than two hours passed quickly. It proves that the processing of the bearing sleeve is about to be completed.

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

The turning tool of the machine tool receded slowly in the eyes of Wang Bin and others, the operation of various parts of the machine tool also began to stop, the safety door of the machine tool was also slowly opened, and the finished bearing sleeve finally appeared in Wang Bin's eyes. Waiting in front of others.

So Wang Bin and this master Zhou immediately went forward with a high-precision measuring instrument to measure the bearing sleeve. At the same time, whether it is good or bad can be seen immediately.

Therefore, whether it is Master Zhou or Wang Bin, their faces are a little nervous. Although in the machining industry, there are always things that fail to process parts, even no matter how precise and automated the equipment is, there is a possibility of processing failure. .

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

Seeing this bearing sleeve that has just been machined,

The first reaction is that it is very beautiful, looks very bright, without any burrs, and feels very smooth as if touching the surface of a glass mirror. At this time, Wang Bin was already concerned about this Bearing sets have some confidence.

After all, this is a bearing sleeve processed by an ultra-high-precision CNC machine tool!

According to the requirements of the 969 Group, the precision level of this bearing sleeve, in fact, only needs to reach the precision of P3 level, which is enough.

Wang Bin had a hunch that the precision of the bearing sleeve processed by the ultra-high-precision CNC machine tool would definitely exceed the level required by the 969 Group.

When Wang Bin was looking at the bearing sleeve, Master Zhou on the side had already started to measure the bearing sleeve, and during the measurement, Master Zhou nodded from time to time, his face full of excitement. With joy.

"Zhou Gong! How's the situation?" Seeing Master Zhou's face, Wang Bin had already expected it in his heart, but he didn't just ask.

"Mr. Wang! The precision of this bearing sleeve is better than I expected. According to my experience, the precision of this bearing sleeve can reach the third grade at most, which is already very good. Although this machine tool says It is an ultra-high precision CNC machine tool.

But in any case, this is a new piece of equipment, and it still needs a certain amount of running-in. Unexpectedly, our country will have such a big progress in the field of machine tools. After that, the accuracy will definitely increase again.

At the same time, it is impossible to adjust the machine tool data in one go, but according to my measurement, the precision level of this bearing sleeve has actually reached the second level.

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

"What, the precision of this bearing sleeve has reached the second level?" Wang Bin said curiously. To be honest, he never thought that it could reach this precision.

However, Wang Bin does not agree with what Master Zhou said about raising the precision level, because according to the requirements of the 969 Group, it is enough to meet the third-level standard.

And now they have reached the second-level accuracy, which has far exceeded the requirements of the 969 Group.

So what we need to do now is to increase the processing speed. After all, the processing time of several hours is too slow for this bearing.

If the other bearing sleeve of this bearing is added, Wang Bin has the final say. They can't process a set of such bearings in a day of Tiangong Technology. How can Wang Bin bear it.

What's more, with such a processing speed, it is impossible to even think about completing the bearing order of the 969 Group within one month.

After all, even if one set can be processed in a day, only thirty sets of such bearings can be processed in a month at most.

However, the 969 Group has more than 90 sets of orders for this kind of bearings. In other words, Tiangong Technology must reduce the processing time to three to four sets of bearings per day.
