In the following days, Wang Bin has been busy in order to acquire the Tianyuan Optical Co., Ltd.

    At the same time, with the help of Qin Meiyu, Wang Bin has 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 the production scale of its production line is only two or three hundred tons per day, but this is enough for Tiangong technology for the time being.

    With the successful acquisition of the two enterprises, Wang Bin made no adjustment to the personnel of the two enterprises except for some financial adjustments. Even Wang Bin, the person in charge of the two enterprises, kept them.

    After all, Cai Yuanxin and others can make their enterprise from a small enterprise to this extent, which means that his ability is absolutely powerful.

    After arranging all the affairs of the two enterprises, Wang Bin returned to Tiangong technology.

    After all, Wang Bin knows very well that the two factories at the headquarters are the foundation of their Tiangong technology compared with others.

    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 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 the operation of the master, a rough bearing sleeve with a diameter of about two meters is slowly lifted to the workbench of the large ultra-high precision CNC machine tool by the lifting equipment in the plant. After all, such a large bearing sleeve has a weight of more than one ton. If the mobile lifting platform in the plant is not used, 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 then the protective cover of the machine tool was slowly closed, and master Zhou and Wang Bin, who operated the machine tool, also stared at the situation in the machine tool.

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

    However, the required precision is not low, so the price is not small, and the required time can not be solved in a few minutes. Processing such a bearing sleeve cannot be completed without a few hours.

    At the same time, in terms of machine tool operators, they also have high technical requirements. Fortunately, the super-high-precision CNC machine tool master of Tiangong technology was asked by Wang Binhua to help Qin Meiyu. His name is master Zhou Fangwei, and he is absolutely competent in technology.

    Metal fragments splashed everywhere in the machine tool, and the machine tool has been running smoothly at an average speed. In the eyes of Wang Bin and others, more than two hours soon passed. At this time, the machine tool also began to withdraw the tool, which proves that the processing of the bearing sleeve is about to be completed.

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

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

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

    Therefore, both master Zhou and Wang Bin are nervous. Although in the machining industry, there are often parts processing failures, even the most precise and automated equipment has the possibility of processing failure.

    However, Wang Bin, master Zhou and others did not hope that Tiangong technology failed to process this bearing sleeve with ultra-high precision CNC machine tools for the first time.

    When I saw the newly processed bearing sleeve, my first reaction was that it was very beautiful and looked very bright without any burrs. It felt like touching the surface of a glass mirror with my hand. It felt very smooth. Wang Bin had a certain confidence in the bearing sleeve.

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

    According to the requirements of 969 group, the precision level of this bearing sleeve is actually enough as long as it reaches the accuracy of P3 level. Wang Bin has a hunch that the precision of this bearing sleeve processed by ultra-high precision CNC machine tool will definitely exceed the level required by 969 group.

    When Wang Bin looked at the bearing sleeve, master Zhou had already started to measure the bearing sleeve. During the measurement, master Zhou nodded his head from time to time, and his face was full of joy.

    "Zhou Gong! How''s the situation?" seeing master Zhou''s face, Wang Bin''s heart had expected, but he not only asked.

    "Mr. Wang! The accuracy of this bearing sleeve is beyond my expectation. According to my experience, the accuracy of this bearing sleeve can reach level 3 at most, which is very good. Although this machine tool is said to be an ultra-high precision CNC machine tool.

    But anyway, this is also a new equipment and needs to be run in. Unexpectedly, our country has made such great progress in machine tools. It''s amazing that it can reach this level without running in. If it is run in, the accuracy will be improved again.

    At the same time, it is impossible to adjust the data at one time, but according to my measurement, the precision level of this bearing sleeve has reached level 2.

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

    "What, the accuracy of this bearing sleeve has reached the secondary accuracy?" Wang Bin said curiously. To tell the truth, he didn''t expect to achieve this accuracy.

    However, Wang Bin does not agree with master Zhou''s proposal to improve the precision level, because if it meets the requirements of 969 group, it is enough to meet the level III standard, and now it has reached the level II precision, which has far exceeded the requirements of 969 group.

    So what we need to do now is to improve the processing speed. After all, the processing time of a few hours is too slow for this bearing. If we add another bearing sleeve of this bearing, Wang Bin calculates. They Tiangong technology can''t process such a set of bearings in a day, which makes Wang Bin how to bear.

    Moreover, with such processing speed, you don''t have to think about completing the bearing order of 969 group within one month.

    After all, even if you can process one set a day, you can only process 30 sets of such bearings a month at most.

    The 969 group has orders for more than 90 sets of bearings, that is, Tiangong technology must reduce the processing time to three to four sets of bearings per day.
