Chapter 99 High-precision large-scale bearing production!

In the following days, Wang Bin has been busy acquiring the Tianyuan Optical Co., Ltd.

At the same time, with the help of Qin Meiyu in recent days, Wang Bin and their Tiangong Technology have also acquired a small and medium-sized special steel smelting enterprise in the city.

It’s just that the scale of this special steel smelting enterprise is not very large, and its production line production scale is only two to 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 the person in charge of these two companies, Wang Bin I also kept them.

After all, Cai Yuanxin and others can make their company from a small company to this level, then it means that his ability is absolutely leveraged.

After arranging everything for these two companies, Wang Bin returned to his own Tiangong Technology.

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

But when Wang Bin returned to their new factory, the ultra-high precision CNC machine tools and the ultra-high precision bearing production line on the new factory area had been installed and could be produced at any time.

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

With a bearing sleeve blank of about two meters in diameter, under the operation of the master, it was slowly hoisted onto the worktable of the large ultra-high-precision CNC machine tool by the lifting equipment in the factory. After all, such a large bearing sleeve Its weight 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 hanging platform in the workshop.

Subsequently, 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 Own’s eyes on the situation in the interior of the machine. .

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

However, the precision required is not low, so the price is not small, and the time required is not a few minutes to solve it. It is impossible to process such a bearing sleeve without a few hours. Finish.

At the same time, the machine tool operators also have high technology requirements. Fortunately, the super-high-precision CNC machine tool master of Tiangong Technology was paid by Wang Bin to ask Qin Meiyu to help find him. The name is Master Zhou Fangwei. In terms of technology, Absolutely competent.

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

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

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

So Wang Bin and the Master Zhou immediately took high-precision measuring instruments and went forward to measure the bearing sleeve. At the same time, whether it is good or bad, you can see the real chapter right away.

Therefore, both Master Zhou and Wang Bin’s expressions are a little nervous, although in the machining industry, parts processing failures often happen, even if it is equipment that is precise and automated, there is a possibility of processing failure. .

However, Wang Bin, Master Zhou and others do not hope that they will fail in the first use of ultra-high-precision CNC machine tools to process such bearing sleeves.

Seeing this newly processed bearing sleeve, the first reaction is that it is very beautiful, looks very bright, and does not have any burrs. It feels like touching the surface of a glass mirror when it is touched by hand. Smooth, Wang Bin already had a certain degree of confidence in this bearing sleeve.

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

According to the requirements of the 969 Group, the precision level of this bearing sleeve is actually sufficient as long as it reaches the accuracy of the p3 level. And this bearing sleeve processed by ultra-high precision CNC machine tools, Wang Bin has a foreboding, the accuracy will definitely exceed The level required by the 969 Group.

While Wang Bin was looking at the bearing sleeve, Master Zhou on the side had already started measuring the bearing sleeve. During the measurement, Master Zhou nodded his head from time to time, and his face was full of With joy.

“Zhou Gong! How is the situation?” Seeing Master Zhou’s face, Wang Bin had already expected something in his heart, but he still asked not only.

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

But in any case, this is also a new equipment that needs a certain amount of running-in. Unexpectedly, our country has made such a great progress in machine tools. It is really amazing. It can reach this level without running-in. , Then the accuracy will definitely be Ascension again.

At the same time, it is impossible to adjust the data at once, but according to my measurement, the precision level of this bearing sleeve has actually reached the second-level level.

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

“What, the accuracy of this bearing sleeve has reached the second-level accuracy?” Wang Bin said with some curiosity. To be honest, he would not have thought that it could achieve this accuracy.

However, Wang Bin does not agree with Master Zhou’s proposal to increase the precision level, because if the 969 Group’s requirements are met, it is enough to meet the third-level standard, and now it has reached the second-level accuracy, which is 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 you add another bearing sleeve for this bearing, Wang Bin has the final say. They Tiangong Technology can not process such a set of bearings in one day. How can Wang Bin bear it?

What’s more, with such a processing speed, if you want to complete the 969 Group’s bearing order within one month, you don’t even have to think about it.

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

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