Chapter 225: Install PK (on)

To be honest, the staff of the industrial laboratory was also taken aback. The precision of each piece of titanium alloy parts taken today is extremely high. According to their measurement, they have reached the level of 0.1 micron. Even the highest precision CNC machining center does not seem to have this precision. Right? Guo
Tailai seems to be very satisfied with the processing accuracy. At least, whether they are Huang Weiguo or Mercedes-Benz staff, they can see Guo Tailai’s satisfied face.
Two days later, the group drove back to the Mercedes-Benz headquarters in Stuttgart. Next, Guo Tailai will assemble two engine parts. Mai
Karen insisted that Guo Tailai install two engines by hand, but Mercedes-Benz has different opinions. Although they have already seen the stability accuracy of Guo Tailai's freehand installation and the improvement of engine performance, Mercedes-Benz still wants to assemble one of the engines.
After the two sides negotiated, they also negotiated with Guo Tailai. Guo Tailai has no opinion on this. He can assemble one engine less and can charge the same fee. Why not? However, Guo Tailai insisted that the whole titanium alloy engine was installed by Guo Tailai, and Mercedes-Benz could install another one.
The installation was carried out in another assembly shop, and an assembly team composed of a senior technician from Mercedes-Benz was holding a variety of tools. On the other side, on the other assembly platform not far from the same assembly workshop, only Guo Tailai is alone. There are also various tools, and Huang Weiguo is all there, but the three of them are just standing next to each other, faithfully carrying out the duties of bodyguards, and they have no intention of intervening. Two engineers on each side who record the relevant processes will check each completed project to ensure that an operation is not missed.
The two engines have the same principle and design except that the materials in some areas are different, the thickness of some parts is different, and the overall weight is different. In theory, the output power and output torque of the two engines should be the same, so the assembly of these two engines became an unofficial little pk of the Mercedes-Benz senior mechanics team and Guo Tailai's assembly skills.
On one side is a senior craftsman carefully selected by the German nationals. On the other hand, a young man from China who is said to be a master is still hand-operated. The machining precision automatic CNC machining center can't match it. If even the senior technician team in assembly is better than that, then Mercedes-Benz should study and research carefully. Whether Mercedes-Benz has been constantly improving in these years. plus
There is no way to work. The light is the difficult-to-machine metal of titanium alloy. Mercedes-Benz has completely admitted that it is not as good as people. Therefore, in the assembly, you must win back and win the beautiful. The vice president in charge of production personally gave them pre-war mobilization, and in any case forced Guo Tailai to overwhelm in order to seize some opportunities in the subsequent negotiations. for
Therefore, the senior technicians selected this time are all the oldest technicians who do not know that Guo Tailai’s engine performance has been improved and the headquarters has been improved. It will not be affected by Guo Tailai’s previous record. Ben
With the pride of Mercedes-Benz, they don't seem to want to take advantage of the time. When Guo Tailai picked up the tools and started to work, he only took action. On the assembly stage, a group of people began to get busy.
Various connecting rod cam valves and so on began to assemble carefully. Guo Tailai looked very relaxed here. The Mercedes-Benz team was not nervous. Everyone acted in an orderly manner, and no one affected each other.
However, when they started to carry some heavy parts, the two sides saw the gap.
Guo Tailai is basically all hand assembled. According to the design of the whole engine, the weight of all the workpieces does not exceed 100 kilograms. It is not a problem for Guo Tailai's metamorphosis at this moment. Therefore, in the final cylinder part, Guo Tailai also installed with both hands, without using lifting equipment. Ben
The team will not be able to do it. Even for the precision of assembly, they have to use lifting equipment to help suspend, as long as the angle is adjusted manually. This
As a result, because the lifting tools are slightly bumpy on the workpiece, even when hanging, the team members are carefully protected, and the natural progress is affected. In terms of speed, the previous people have high efficiency. The leading advantage has also been tied by Guo Tailai a little bit. Guo
The assembly of Tailai has been incomprehensible. The v-shaped cylinder, Guo Tailai stretches his hand and grabs the piston to enter the plug. It is not afraid that the slight deviation of the angle will lead to the installation is not smooth and the friction during the post work is intensified. It is reasonable to say that this method of not measuring the whole feeling of the eyes should be completely abandoned. It is replaced by high-precision mechanization. However, when Guo Tailai was installed, it was so easy, and there was no point at all. The situation is simply unbelievable. special
When Guo Tailai held the top half of the cylinder with his hands on the lower cover, the Mercedes-Benz team was careful even with the lifting equipment. All the operations were all breathless, almost one millimeter and one millimeter. It is a slight adjustment. Can Guo Tailai over there? It was so easy to put it on, he is not afraid of it?
Although everyone can't believe it at all, Guo Tailai has already started to screw the nut. Look at the ease of inserting the screws, indicating that the up and down is still very accurate. However, it is obvious that Guo Tailai is installed with both hands. How is the strength of the human arms? very
Obviously, in the later stage of assembly, the installation of the Mercedes-Benz team has been interfered by Guo Tailai's action. Regardless of what Guo Tailai does, and which process to do, those senior technicians will always look at it here. All kinds of suspicions and shocks are unbelievable, which makes the installation efficiency of the Mercedes-Benz team several times lower. most
The end result is that when Guo Tailai has already installed this 85-kilogram all-titanium engine, the part of the Titanium engine installed by the Mercedes-Benz team is still in the final steps. Do
There is no difference in time between the ten minutes, but the senior technicians of the Mercedes-Benz team have completely lowered their proud heads. Ten people worked together ten minutes later than others, regardless of the quality of the assembly, the first assembly efficiency lost. Connect
Down, the two sides did not disassemble each other's engines and appreciated the engine installed by the other side. At this stage, Guo Tailai, Mercedes-Benz installation team, did not comment on the engine installed by the other side. It
After that, both engines were filled with lubricating oil, coolant was added, and the power was turned on. On the test bench, comprehensive inspection after startup was performed.
