Chapter 206: Engine test bench

The machining accuracy of CNC machine tools is divided into three or six or nine. In later generations, the average machining center can reach about 0.005 casually, and if repeated positioning is performed, it can be reduced to less than 0.002, which is already a processing level that ordinary CNC machine tools can reach. Coupled with the grating, the accuracy will be further reduced to below 0.001.

The main difference between high-level machine tools and low-level machine tools is the number of controlled axes. The more axes that can be linked, the more complex curved surfaces can be processed.

This kind of three-axis linkage CNC machine tool is not difficult at all. It belongs to the lowest level device. Although Qin Guan deliberately found some backward CNC machine tools, the machining accuracy has exceeded the level of the 1970s.

The industrial level of the music country is not the strongest in the West. The music country is the strongest.

At the end of the 1970s, their machining accuracy is no longer low, but in this ancient country, they actually found a higher accuracy than their own!

How can this make Sandra not surprised?

In fact, Han Guo's machine tool level in the 1990s was also lagging behind. However, at that time, global technology was advancing, especially the improvement of linear motors, which allowed Han Guo's machine tools to enter the fast lane. This kind of ordinary three-axis machine CNC machine tools have reached the global standard at that time.

And now, it's a surprise.

Sandra was overjoyed, and then processed the second and third. Unknowingly, more than a dozen workpieces have been processed. The average precision is within 0.002!

"Unexpectedly today, you have become a model worker?" At this moment, Qin Guan had finished dinner and was chatting with Chen Yutong and her parents. Xiang Jing came over and said briefly to Qin Guan. Suddenly, Qin Guan was too Very strange.

Is it because you know you can't go, you can't find a channel to contact, and you work honestly before the letter is sent to the embassy?

No, there must be other circumstances!

"Don't worry about her for now, just watch the developments." Qin Guan said, "In short, we have already started our own production. This is good news. The next step is how to get her to take the initiative to accept apprentices. I think we can give her. Increase the number of points and let her work day and night. In this way, she can't help herself, so she will naturally look for help.

Xiang Jing nodded: "Sure, but this helper must be the first to find Heriba."

Why? Is that still necessary?

This woman has been holding back for several days, and her body is calling for the caress of a male. Heribala is the most suitable. Secondly, Heribala's education level is not high. How can the Great Yangma teach it? However, he will not infer other things, so that CNC machine tools are equivalent to wasted.

Now you can only process the oil pump according to the entered program, but other things cannot be processed.

This Great Yangma is not easy to tame, but if it is really tamed, it looks good under Heriba’s crotch. We also have foreign aid. The Great Yangmar comes from the West and is rich in knowledge. It will be beneficial to the factory without any harm to the factory.

However, this road has a long way to go. People come here now as spies.

No matter, let's talk about it!

The next day, the engine workshop.

"Where is the test bench?" After finishing the morning run and having breakfast, the workers just started walking into the workshop when the voice of a woman who was holding her feet heard.

Although it hasn't been a few days since Dayang Malay Factory, the gossip has spread long ago, this woman, tut. Now, this woman, why did she run her own workshop?

However, none of them turned their heads. The former workers were laid off just because of the excitement. Now, these workers transferred from other workshops are most in compliance with the order of the factory.

Test bench? Upon hearing Dayangmar’s question, the newly appointed deputy director of the workshop shook his head: "No."

"What? You don't even have a test bench?" Sandra felt that her cognition was collapsing, so why did you say that this was developed by yourself?

If it is a positive research and development, it needs to do a lot of tests. Among them, the engine test bench is indispensable. It runs on the bench for thousands of hours to test whether the various design parameters of the engine can meet the standards.

Now, the other party doesn't even have a test bench, and they say they developed it themselves? Obviously, it was reverse surveying and mapping one's own side, and then directly began to build.

Damn it!

Coming here today, Sandra brought the oil pump with the highest precision that she processed yesterday. I hope to install it on the engine and test it to see if this high-precision oil pump can effectively improve the engine’s power and reduce fuel consumption. This requires a test bench.

Who knows, there is no other party!

what's next? How to do?

At this moment, Sandra saw a familiar figure.

As the person in charge of the heavy-duty truck project, Heribala travels around the workshops every morning. Now, when I turn here, I see Sandra coming here.

what happened?

"You don't even have a test bench when you produce engines. How can this be done? How do you know whether the engines you produce have reached the design targets?" Thinking of the soaking cage that day, when Sandra was crowded with people, Convergent, without flirting, just like doing business.

"Yes, we just don't have one." Heribala said: "What's the matter?"

To put it bluntly, Sandra was about to vomit blood: "My new fuel pump is qualified or unqualified. How do you know? Compared with the imported one, how do you know if it has improved?"

"Just load it into the car, and just go out and try it." Heribala said.

The wisdom of the working people is endless. The engine is powerful and sluggish. You will know it after a try. It is more intuitive and effective. What test bench is needed!

"You!" Sandra was also speechless with anger, do you know what scientific laws are? Loading test? Is there any specific data?

What a bun!

"Ms. Sandra, your proposal is very good. Maybe we should have a test bench." At this moment, a voice rang from behind: "However, our technology in this area is still very weak. For the test bench, I hope you can provide some help."

Qin Guan walked in.

The other party actually said that he wanted a test bench. Of course, Qin Guan had to meet this requirement. He lacked talents. Of course, the labor force hired at such a high price would have to be used. Various uses have drained all her oil and water!
