Chapter 496 Machining Center Completion (Part 1)
Guo Tailai still smiled wryly. Brother Hai was a little puzzled, he could pay in installments, why did he still have this expression?
"Well, I still have a piece of land in the capital, and I want to build a company headquarters." Guo Tailai sighed and said, "Not only do we need to build a building here, but we also need to build various high-end laboratories. That is more expensive."
Buildings built in the capital, high-end laboratories, neither of these two can be won with a little money. Even Brother Hai feels a little sympathetic to Guo Tailai now.
Originally, ordinary real estate projects can be loaned. As long as the land is won, the land can be mortgaged to start the construction work later. But Guo Tailai was unwilling to take out loans. Without a mortgage, it would be too difficult for a new company that could not even see profitability.
It can almost be said that the company in Beijing was supported by Guo Tailai alone. For the time being, it is still relying on the capital investment of the last sold model. Although it seems to be as high as more than 100 million US dollars, how long it will last is still open to question.
Brother Hai knows about beauty salons and Guo Tailai's special plastic surgery skills, but he can't advise Guo Tailai to do more plastic surgery clients. Guo Tailai has to pay a price every time he does it, he must not let Guo Tailai damage his body and make money.
"Take your time." What else could Brother Hai say? I can only persuade you like this: "Or, you can try to raise money from Mr. Ding or Mr. Cheng. I believe they will be willing to invest in your company."
"Forget it, that's the only way to go, let's take it slowly!" Guo Tailai doesn't want others to intervene in his company for the time being, and he will talk about it when he can't hold on.
Although there is no way to help Guo Tailai solve the funding problem, Brother Hai can still help Guo Tailai find a way to win the land in Gusu. Xiaohui volunteered and offered to go to Gusu to help Guo Tailai coordinate, but Guo Tailai couldn't get in the way, so he could only nod in agreement.
The materials from Professor Wang's side have been delivered to the island one after another. Guo Tailai went back to rest for a night, and then devoted himself to the intense process of making parts the next day.
When all the materials are delivered here, they have been placed for more than 24 hours to adapt to the temperature here, and there will be no stress or expansion size caused by internal and external temperature differences. The island has complete anti-seismic trenches and anti-seismic walls, which is definitely the most suitable place for high-precision machining.
Compared with the two large flat fixed plates, the other parts are smaller in size and easy to manufacture. In less than a week, all the parts have been completed, and only assembly and debugging are left.
Almost all of the several research groups in Professor Wang's laboratory were dispatched, including the second brother in the dormitory who hadn't seen much for two years after graduation. The evildoer has always been the evildoer, he is in charge of the electronic control part, and several papers have been published. It is estimated that after the completion of the ultra-high-precision numerical control, the second brother will be able to meet the direct Ph.D. graduation standard in just two years after finishing the last thesis.
Guo Tailai was responsible for assembling according to the drawings and coordinating the tolerances. Mr. Liu served as the on-site guide. A group of doctoral and master's students all worked together to carefully move certain parts according to Guo Tailai's requirements. There were also four master students on the scene recording according to Guo Tailai's assembly process, and every step must be written down in detail. Including the height and speed at which it is lowered, the number of screws and nuts that have been twisted a few times at a torque, and how many degrees to release the stress, and so on.
At each step, Guo Tailai and Mr. Liu explained why they did this, what effect it could achieve, and what part of the workpiece error caused the need for reverse adjustment and matching tolerances. These experiences were all stated and recorded. In the future, this detailed assembly manual will be the assembly guide for assembly engineers after mass production.
The stepper motor here is a scheme developed by the Department of Motors, and it is also a design completed by a doctoral supervisor with several doctoral and master students. The production is also manually assembled by Guo Tailai, and all assembly records are still detailed to the strength and angle of each movement.
Lubricating oil and coolant are independently developed by two professors from the Department of Chemistry and Department of Mechanics. They have low volatility and high purity, and are equipped with a high-mesh screen for filtration. Lubrication must be considered during the installation process, and the matching coolant pipelines will also be installed.
After assembling these and adjusting the tolerance, Guo Tailai installed the circuit board according to the requirements of the second brother. The control program has been run hundreds of times on the simulator. Except that the control accuracy of the simulator cannot meet the high-precision requirements and there is no way to test it, all other tool changes, tool changes, angle rotation, forward, backward, feed, and retract have all been simulated. all over. After the control system is installed, clean up the sundries to release static electricity, and only after all irrelevant people have exited, do the electrical test.
Guo Tailai thought that the power-on test could only be carried out by a few subsystem research teams within the school or even by internal personnel in the laboratory. At least wait until the test passes and the function is ok before reporting to the leadership. But what he didn't expect was how much the country attached importance to this newly designed purely domestic ultra-high-precision five-axis CNC machining center.
Not only the leaders of the Department of Precision Instruments rushed over from the school, but also the leaders of several departments of the Department of Chemistry, Mechanics and Electrical Engineering, and even the leaders of the school, and Principal Wang was among them. Not only that, the Ministry of Information Industry also came to several leaders, and the Huaxia Academy of Sciences and Huaxia Academy of Engineering each came to a few academicians, and the ranks of the teams were frighteningly high.
Professor Wang is the controller and overall planner of the overall project. Most of the theories and designs are his ideas, but it is Professor Wang and several of his students who actually realize it. The second brother is in charge of the control system project, so the second brother is still in charge of the specific demonstration operation.
In order to avoid the vibration caused by the operator's actions at close range from affecting the machining accuracy, the console is connected by a data cable away from the machining center. Once the operator secures the workpiece, he closes the two-story safety doors and moves away from the machining center.
The second brother sat in front of the console, took a deep breath, and under the watchful eyes of a group of big and small leaders behind him, he turned on the switch, turned on the power, and started the system. Watching the console screen light up, showing the system self-test interface that I have seen countless times, I let out a light breath. At least so far, everything is working fine.
The control system starts to initialize, and the cutter head starts to self-check from the initial state. After a very smooth rotation, the wheel with various knives fixed on it enters the standby state. At the same time, the most central processing axis flexibly rotated a few circles, and then accurately stopped at the very center.
The system interface displays a series of self-test passing information, and each subsystem self-test is normal. Afterwards, the entire system completes the self-test and enters the working interface.
"From the current point of view, everything is normal." The second brother in front of the console said this conclusion happily.
