Chapter nine hundred and eighty transformation city Dortmund
Hoffman explained in detail.
"Does the fastest car always win the race? Anyone who watches a car race knows that there are other factors besides speed that influence the outcome of the race.
First of all, it is very important for the driver to understand the track. He must know where there are sharp turns so that he can slow down in time and pass the corners safely and efficiently.
When we use high-speed processing of molds, the digital display technology for monitoring the trajectory to be processed can obtain information about the appearance of sharp curves in advance. This function plays the same role.
In addition, when a driver drives around the track, the consistency of his movements, whether he can brake and accelerate skillfully, etc. have a very important impact on the driver's on-the-spot performance.
From this, we designed our own bell-shaped acceleration and deceleration. The rail to be processed uses slow acceleration and deceleration instead of sudden speed changes to ensure the smooth acceleration of the machine tool.
In addition, there are other similarities between racing cars and mold processing technology. For example, the power of a racing car engine is similar to the drive device and motor of a machine tool. The weight of a racing car can be compared with the weight of the moving components in a machine tool. The stiffness and strength of a racing car are similar.
Due to the strength and stiffness of the machine tool, the ability to correct specific path errors is very similar to the driver's ability to control the car within the lane.
Another situation similar to our current situation is that those cars that are not the fastest often need drivers with comprehensive skills.
In the past, many people thought that it was very difficult to ensure high machining accuracy while cutting at high speed, but now, because the process has been greatly improved, even ordinary machine tools can complete the work satisfactorily."
As he walked, Hoffman talked and checked the machine tools being processed from time to time, eager to tell the other party the essence.
"Wow, doesn't that mean your company is already number one in the world?"
"Haha, we are still far from being the best in the world. We are just a small company. Our current process can only be said to have achieved the best performance according to the current product status. There are many factors that limit the maximum feed speed of mold processing. The main ones are
Technology is difficult. If you want to improve technology, you must master higher technology on the one hand, and improve the mechanical structure of the machine tool on the other hand.
The performance of current machine tools is still far from reaching the limit, so we still have a long way to go.”
Liu Lang nodded. Hoffman's Company C is indeed a very good company, and the level of these workers is indeed very high, much better than the employees of Norinco. Of course, this is not a matter of personal ability, but a matter of personal ability.
It is the inheritance of industrial technology. In terms of basic skills, the two are almost the same. What our workers lack is just the accumulation of knowledge.
Company C's knife manufacturing process mainly focuses on the sharpening of the blade, the design of the blade, and the uniqueness of the forging of the round knife. The other party really showed many core secrets, such as on the digital display screen.
There are a lot of parameters, even Liu Lang gained a lot of insights after more than two hours of visiting.
"Mr. Hoffman, your factory is really an eye-opener for me. I believe that my friend will definitely cooperate with you. I will tell him when I get back, and you can just wait to contact him!"
Liu Lang has decided to cooperate with the other party and purchase seven types of knives in the first batch. He will buy tens of thousands of sets first.
Hoffman smiled and did not show how happy he was. In his eyes, orders from China were dispensable. Even if they were available, they would probably not cost much. After all, the Chinese market was too low-end and most companies could not use it.
He wanted to buy his products, but he was very happy even if there was no order, because he met the chairman of Shengtang Company, and this kind of network was not something anyone could control.
At noon, Liu Lang had a meal in the canteen of Company C. The food was not bad, just ordinary food.
After dinner, Liu Lang said goodbye and left, and Hoffman personally drove the two of them back to the hotel.
Today’s trip to Bochum is over, the next stop is Dortmund.
The two of them did not stop in Bochum and directly bought a train ticket to Dortmund. Both cities belong to the Ruhr area, so the distance is very close, less than 50 kilometers. The train will arrive at the station half an hour later.
Dortmund is also a very famous city in Germany. Its specialties are steel and beer. However, this city was originally rich in coal and gradually grew by relying on coal. However, with the continuous mining, it became a resource-depleted city. This is similar to Fucheng, but
Dortmund rapidly transformed through industrial manufacturing and eventually became an important city in the Ruhr area. There are many more factories in Dortmund than in Bochum.
It was only four o'clock in the afternoon when Liu Lang and his wife arrived in Dortmund. They took a taxi to the city center. What they saw along the way were large green spaces and parks. All the so-called industrial zones were in the suburbs. There were no industrial enterprises in the city anymore.
This is also a characteristic of cities in transition. The original resource-based cities left local residents with not only economic difficulties, but also environmental damage.
This is especially obvious in Fucheng now. A large subsidence area has begun to affect the lives of residents. Almost nothing can be done in this subsidence area, and the land is equivalent to a waste.
Twenty years later, the subsidence area in Fucheng will cover an area of more than 100 square kilometers, most of which is around the city. Don't even think about building buildings. People's mud houses often suffer from sinking and cracks. Who dares to build
building?
In addition to the damage to land resources, there is also the impact of the spontaneous combustion of the gangue mountain on the air and the pollution of the land. These are not the most serious. The huge open-pit mine covering an area of more than ten square kilometers and the deepest point of 300 meters is really a
"Pit", this big pit is like a scar in Fucheng. It took the miners of Fucheng fifty years to dig it out. It will probably take another fifty years to fill it up.
Land subsidence, land pollution, and air pollution are problems for all resource-depleted cities. Therefore, cities that have successfully transformed have all made greater efforts to improve the environment, and this is the case in Dortmund.
Liu Lang chatted with the driver. Seeing that the yellow-skinned kid spoke German so well, the driver thought he grew up in Germany. When he heard that the kid was Chinese, he thought for a moment. Was he thinking about China?
What kind of country is it? In the 1980s, Westerners’ understanding of China was almost zero.
We stayed at a Hilton Hotel in the city center and had dinner. Liu Lang and Sun Hu walked around the streets of Dortmund for more than an hour. This city is a little better than Bochum. At least there are some bars around eight o'clock in the evening.
In business.
There are basically no entertainment venues open after eight o'clock in Bochum. In fact, there are no entertainment venues in the whole of Germany. The bar is the only place for them to gather, especially when there is a football match, a large number of fans will gather here to drink.
