Chapter 450 Nanoscale Calibration (Part 1)
The first thing Guo Tailai did when he arrived at the Mercedes-Benz headquarters was to see the dust-free workshop with some machinery but mostly hand tools.
Because of Guo Tailai's special request, this workshop is not as open as last time, and there is no way to see the inside from the outside. If you are not in the workshop, there is no way to see how Guo Tailai works.
Guo Tailai inspected the tools carefully. There are two sets of all tools, one for use and one for backup. Guo Tailai inspected each of the two sets, and even tried it on a prepared titanium alloy blank. This piece of work is completely for Guo Tailai to try, not an official work piece.
Guo Tailai is very satisfied with the rigor of the Germans and their serious style. All the tools are very exquisite, even if they are used by Guo Tailai by hand, they are all polished and seem to be mass-produced, but each set is no better than Liu. The set in the old studio is poor. In terms of materials alone, they are better than those there. It cannot be denied that there is still a certain gap between China and some foreign countries in terms of basic materials science. This is a fact.
While Guo Tailai was checking the tools, Huang Weiguo and the others were checking the workshop. They have only one task, to ensure that there are no cameras in the workshop, and no one can see Mr. Guo's work.
The three of Huang Weiguo are very concerned about this. They know what Guo Tailai means to domestic finishing. Although the country has not restricted Guo Tailai’s freedom to go abroad for the time being, since they are protecting Guo Tailai, they cannot allow Guo Tailai’s exclusive craftsmanship to be stolen. Steal away. Even if Guo Tailai has some skills that others can't learn if they want to, but be prepared, right?
The three of them also checked very carefully, and Liu Zhizhuan even took an electronic instrument to check. This is an anti-eavesdropping and anti-candid camera detection tool used by special front agents. After careful inspection, the three of them ensured that there were no hidden cameras or eavesdropping tools in the workshop.
Then, next, Guo Tailai's task is to go back to the hotel room to rest immediately after a big meal, and reverse the jet lag as soon as possible. The titanium alloy engine is a precision part, and it can only work after rest and energy.
The Mercedes-Benz company attaches great importance to it. In addition to the clean room, there is an inspection studio next to the work room in the same clean environment. Every workpiece that Guo Tailai makes must be measured here first. After all the workpieces are completed , will bring a few of them to that industrial laboratory for measurement with a laser interferometer.
McLaren also received the notice, and their technical director also rushed to the Mercedes-Benz headquarters one day after Guo Tailai arrived. In fact, the two companies have been waiting anxiously. Everything was ready before, but Huaxia started to celebrate the Spring Festival. After waiting for a month, they finally waited for Guo Tailai to come to work. They all wished to see Guo Tailai's results immediately. up.
When the technical director arrived, Guo Tailai was carefully looking at the design drawings, frantically constructing the three-dimensional structure of the engine in his mind. While constructing, Guo Tailai calculated. After the construction was completed, Guo Tailai even proposed several areas for improvement.
These points are mainly in the thickness of the workpiece. The engine is made of all-titanium alloy, which has excellent performance and strength. In some cases, some dimensions can be appropriately reduced to reduce weight. Although the designers of Mercedes-Benz have appropriately reduced some dimensions, according to Guo Tailai's own calculations, the result is that some dimensions can be appropriately reduced in these positions, mainly the thickness, and the weight can be further reduced.
Of course, Guo Tailai only made a suggestion, whether Mercedes-Benz and McLaren will agree, Guo Tailai is not sure. But what Guo Tailai did not expect was that the two sides attached great importance to this, and held a meeting with designers and engineers overnight to study and calculate. When Guo Tailai passed by in the morning, the technical director expressed to Guo Tailai in an unusually admiring tone that the size suggested by him could be completely followed. to process.
The size suggested by Guo Tailai, after calculation by a bunch of designers and engineers, can actually reach the strength level of the existing engine. And this number is too accurate, it happens to be at the position where the maximum strength of their engine design is 5% more than the margin, any more will be wasted, and any less will be unsafe, it is simply wonderful.
This greatly admired the technical director. You must know that in order to verify this figure, dozens of them calculated for most of the night, while Guo Tailai seemed to have only one person who looked at the engine drawing for an afternoon. Mercedes-Benz dared to swear that the design drawings were just shown to Guo Tai when the technical director arrived. It is unbelievable that Guo Tailai, besides looking at the pictures, can give such accurate figures.
In particular, there are two types of design drawings, one is a partial titanium alloy, and the other is a full titanium alloy. Guo Tailai gave the numbers separately. This can only show that Guo Tailai is not only a master of finishing, but also a master of engine design. Just the change of these numbers has greatly increased the confidence of Mercedes-Benz and McLaren in Guo Tailai.
All the workpieces have been prepared, even some workpieces have been processed into rough blanks, Guo Tailai only needs to finish machining. However, it is limited to cast iron and aluminum alloy, and the titanium alloy part can only be done by Guo Tailai himself.
Guo Tailai did not disappoint the anxiously waiting Mercedes-Benz and McLaren, and finished processing all non-titanium alloy parts in only one morning. Of course, it was after Huang Weiguo and the other three checked the workshop again and stood guard at the door of the workshop. For all the completed workpieces, Mercedes-Benz's most skilled inspectors used the highest-precision measuring tools in their headquarters, and the measured results made people go crazy.
They are in Germany. In Germany, which is known as the most powerful automated processing, they use the highest-precision automatic CNC machining center. The machining accuracy is not as good as that of a hand tool that is polished bit by bit. How can this be human?
When Guo Tailai started processing titanium alloy, and the speed was only 50% slower than processing aluminum alloy and cast iron, the vice president in charge of production at Mercedes-Benz couldn't sit still after hearing the news. The first thing Guo Tailai did when he came out of the workplace was that the vice president wanted to have a detailed discussion with Guo Tailai about further cooperation.
Titanium alloy high-precision machining, if such a method can be promoted on a large scale, just because of the gimmick of this all-titanium alloy engine, the sales of a large number of top-end cars can be doubled, right?
"We can talk after I finish these two engines and test their performance, okay?" Guo Tailai didn't refuse, but he still wanted to see the results, at least so that both parties would have a reference.
