Chapter 225： Nanoscale calibration (on)

The first thing that Guo Tailai rushed to the Mercedes-Benz headquarters was to go to the dust-free workshop where there were some machines but most of them were hand tools. because

For Guo Tailai's special request, this work room is not as open as the last time. There is no way to see it inside. There is no way to see how Guo Tailai works. Guo

Tailai carefully examined the tools. All the tools, there are two sets, one set, one set as a backup. Guo Tailai tested each of the two sets and even tried it on a prepared titanium alloy billet. This piece of work is completely for Guo Tailai to test, not a formal workpiece. De

Guo Tailai is very satisfied with the rigor of the Chinese people and their serious style. All the tools are very beautiful. Even if they are used by Guo Tailai, they are all polished. It seems to be mass-produced, but each one is not more than Liu Lao. The set in the studio is poor. It is higher in materials than in the past. It cannot be said that in terms of basic materials science, there is still a certain gap between domestic and some foreign countries. This is a fact.

While Guo Tailai was checking the tools, Huang Weiguo and the three of them were checking the work room. There is only one task for them, ensuring that there is no camera in this workplace, and no one can see the work of General Guo.

Huang Weiguo is very concerned about this. They know what Guo Tailai means for domestic finishing. Although the state does not restrict Guo Tailai’s freedom to go abroad, since they are protecting Guo Tailai, they cannot let Guo Tailai’s exclusive craft be accepted. Stealing away. Even if Guo Tailai has some craftsmanship, others can't learn it, but is it prepared? three

People also checked very carefully, and Liu Zhizhu even took an electronic instrument for testing. This is a detection tool used by special frontline agents to prevent eavesdropping and anti-sneak shots. After careful inspection, the three ensured that there were no hidden cameras and eavesdropping tools in the workplace.

Then, next, Guo Tailai's task is to return to the hotel room and rest immediately after a big meal, and turn the time difference back as soon as possible. The titanium alloy engine is a precision piece, and it takes a good rest to work. Ben

Chi company attaches great importance to it. In addition to the dust-free work room, there is a test studio with the same dust-free environment next to the work room. Every workpiece that Guo Tailai has to do must be measured here first, after all the workpieces are completed. Only a few of them will be taken to the industrial laboratory for measurement with a laser interferometer.

McLaren also received a notice, their technical director also arrived at the Mercedes-Benz headquarters after Guo Tailai arrived one day. In fact, the two companies have been waiting for some anxiety. Before everything was ready, Huaxia started the Spring Festival and waited for a month for the scalp. After waiting for Guo Tailai to come to work, they all hated to see the results of Guo Tailai. It is.

When the technical director arrived, Guo Tailai was carefully looking at the design drawings, and the three-dimensional structure of the engine was built madly in his mind. On the one hand, Guo Tailai calculated that after the construction was completed, Guo Tailai even proposed several places for improvement.

These are mainly in the thickness of the workpiece. The engine is made of all-titanium alloy, and the performance is excellent. In some cases, some sizes can be appropriately reduced to reduce the weight. Although Mercedes-Benz designers have appropriately reduced some of the dimensions, Guo Tailai's calculations have shown that the size can be appropriately reduced at these locations, mainly thickness, and the weight can be further reduced. when

However, Guo Tailai only made suggestions. Mercedes-Benz and McLaren will not agree, and Guo Tailai is not sure. However, what Guo Tailai did not expect was that the two sides attached great importance to this. They gathered designers and engineers to study and calculate at night. When Guo Tailai passed in the morning, the technical director expressed to Guo Tailai in an unusually admirable tone that he could completely follow his recommended size. To process. Guo

The size recommended by Tailai, after a bunch of calculations by designers and engineers, actually can reach the strength level of the existing engine. And this number is too accurate, just in the position of their engine design with a maximum strength of more than 5%, more waste, and less unsafe, it is so wonderful.

This made the technical director greatly admire, to know that in order to verify this number, they counted dozens of people to calculate the majority of the half, and Guo Tailai seems to have only one person to see the engine drawings for one afternoon. Mercedes-Benz dared to swear that the design was the technical director when they just came to Guotai to see, Guo Tailai alone in addition to looking at the map, even can give such a few precise numbers, it is incredible.

In particular, the design drawings are two, a part of titanium alloy, a full titanium alloy, Guo Tailai is given a number. This can only show that in addition to being a master of finishing, Guo Tailai is really an engine design master. It is only the change of these figures that the confidence of Guo Tailai in Mercedes-Benz and McLaren has increased. Place

Some of the workpieces have been prepared, and even some of the workpieces have been processed into rough embryos. Guo Tailai can be finished as long as it is finished. However, only limited to cast iron and aluminum alloy, the titanium alloy part can only wait for Guo Tailai to do it himself.

Guo Tailai did not disappoint the awaiting Mercedes-Benz and McLaren. It took only one morning to process all the non-titanium parts. Of course, it was after Huang Weiguo and other three people re-examined the work room and stayed at the door of the workplace. All the finished workpieces, Mercedes-Benz's most skilled inspectors, used the most accurate measurement tools from their headquarters, and the results were simply maddening. he

However, in Germany, in Germany, which claims to be the most powerful in automated processing, it uses the most accurate automatic CNC machining center. The precision of machining is not as good as the precision of grinding with a hand tool. How can this be so? Wait

When Guo Tailai began processing titanium alloys, and the speed was only 50% slower than processing aluminum alloys and cast irons, Mercedes-Benz's vice president in charge of production had already heard the news. The first thing that Guo Tailai came out of the workplace was that the vice president hoped to talk to Guo Tailai in detail about further cooperation.

High-precision machining of titanium alloys. If such a method can be promoted on a large scale, it is the gimmick of this all-titanium engine. Can a large number of top-loading cars be sold several times? "

When I finish the two engines, let's talk about the performance and then talk about it, can we? Guo Tailai did not refuse, but he still wanted to see the results, at least that both sides will have a reference.
