Chapter 98 Where is the problem?

"Look, the leaders are all big leaders."

"I heard that there is a problem with the turbine blade broaching process of the turbo shaft eight, and it seems to be true."

"."

Some workers at the production site were very curious. Seeing such a large group of people walk into the workshop site, they began to discuss quietly.There is basically no secret at all in the same workshop. Many people know that there is a problem with the turbine blades of the turbo shaft eight.

Everyone soon arrived at the broaching machine where the tenons of the blades were processed.

This is an old horizontal broaching machine, imported equipment in the 60s, which has been used for more than [-] years.

No way, even though it is a military enterprise, it is not all advanced CNC equipment. It will take at least ten years to achieve this point.

At the beginning of the 21st century, the numerical control rate of the military industry, especially the aero-engine manufacturing enterprises, has reached more than [-]%. Most of the equipment is imported high-precision equipment.

Now, the numerical control rate is only about [-]%. Such a large Phoenix factory does not have a single numerical control broaching machine.

Everyone got busy next to this semi-old horizontal broaching machine. The first thing to suspect was of course the broaching tool.

"Mr. Wang, let's first check the broach, especially the fine broach, whether there is any slight chipping or burrs on the edge." Zheng Xuewen, the deputy director of the Engineering Technology Department, suggested.

Wang Tianfang nodded, he also thought so, first of all, of course, check the broach, especially the fine broach.

"Old Pan, you are an expert in the design of broaches, you should take a look at the situation of fine broaches first."

"Okay, Mr. Wang."

Pan Guohua is in his fifties and wears a pair of glasses. He is a senior engineer in tool design, especially in broach design.

He picked up the fine broach and looked at it carefully, every tooth and every edge was carefully looked at.

He even took a magnifying glass and looked at it under the light for a while, then his brows frowned slightly.

Should not be!

How did that happen?

This fine broach is very exquisite in workmanship, without any burrs, and the cutting edge of each tooth is also very complete, without any chipping.

"Mr. Wang, there seems to be no problem with this broach."

"Oh."

Wang Tianfang frowned slightly, took a magnifying glass to see for himself, and then said loudly, "Minister Zheng, Section Chief Qin, you are all experts, take a look at this broach to see if there is any problem."

Zheng Xuewen, Section Chief Qin of the Tooling Design Section carefully looked at the condition of the broach, and then frowned.

Should not be!

It can be confirmed that there is no problem with this fine broach, so how did the groove on the tenon of the blade come from?

There is really no solution.

Everyone carefully checked the fine broaching tool, the broaching jigs in this process, and even the condition of the machine tool and the condition of the broaching sample.

Everything seems to be ok.

No one knows what the problem is.

This is strange, everyone looks at me, I look at you, some people even shake their heads and smile wryly, what the hell, I thought it was a very simple problem. .

Zheng Xuewen was a little unbelieving, and suggested, "Send this fine broach for inspection, and we must see the inspection results as soon as possible. By the way, we must magnify it by 50 times for projection."

Therefore, this fine broach was quickly sent to the inspection room, and someone soon carried out a detailed inspection on it.

Lin Feng has been standing by the side, watching all this quietly.

All the big bosses present, he is a small soldier, of course he can only stand aside and watch everyone analyze the problem.

Didn't find out where the problem was.

Lin Feng was slightly surprised, his heart moved, and he communicated with the system in his mind.To be honest, he couldn't see where the problem was, and he always believed that the problem should be the precision broach.

Since you don't know where the problem is, then ask the system, this guy must know, otherwise, it is not a system.

"System, what do you think is the problem?"

The system suddenly got excited, "I will tell you where the problem is, but it will consume one time to help you solve the problem."

Lin Feng said intentionally, "This should be counted once."

"Of course it counts as one time. Last time I solved a problem for you for free. It was a big loss. This time it must not be free."

A total of 20 technical problems can be solved by the system. So far, none of them have been consumed, so let’s consume one today.

Lin Feng didn't plan to go whoring for nothing today, and he was surprisingly straightforward, "Okay, that counts as one time, and you tell me what the problem is."

The system was taken aback, what happened to the host today, he was so cheerful, could it be because he was in a good mood today.

After being slightly taken aback, it still instilled the problem, how to solve it, etc., into Lin Feng's mind at once.

After receiving the information, understanding where the problem is and how to solve it, Lin Feng said, "Is it that simple?"

The system said, "Yes, it's that simple."

Lin Feng said it was a big loss today, such a simple problem actually consumed the number of times the system helped solve technical problems.

"System, let's discuss it. If it's that simple, how about not consuming one time this time?"

"no!"

The system definitely disagrees.

Lin Feng is destined to still be unable to prostitute for nothing today, counting birds, just consume once, anyway, there are still 19 times.

The inspection results of the fine broach came out very quickly, all the dimensions were qualified, and there was no problem in the projection inspection.

Since there is no problem with the fine broach, what is the problem?
An engineer reminded, "Is there something wrong with our broaching machine? After all, it is a 60s equipment, and it is a bit old."

The technical director of the blade workshop immediately denied this speculation, "There is no problem with the broaching machine. Although it is a 60s equipment, we inspect it every year and maintain it every day. Just two days ago, it processed a batch of turboprop six turbine blades. Passed, and there is no quality problem."

There is no problem with the machine tool.

Fine broaching is no problem either.

As for the jig in this broaching process, is there a problem with it, but this possibility has also been denied. The jig has just returned from inspection, and the inspection mark on it has not been torn off.

Wang Tianfang pondered for a while, then looked around at all the people present, his eyes swept over everyone's faces one by one.

"Comrades, if anyone has a different idea, feel free to speak up."

However, the scene was quiet and no one spoke.

Wang Tianfang smiled wryly, his gaze fell on Lin Feng unintentionally, and he inadvertently asked, "Xiao Lin, you are also a half-expert in broaching technology, do you have any opinions or opinions?"
