Chapter 413 Three guarantees and one
Gu Zhengxin's face changed slightly.

The several production supervisors and technical supervisors who accompanied him noticed this, and one of them asked, "Mr. Gu, what's the matter?"

Gu Zhengxin did not hide anything, sighed softly, and said in a low voice: "There is a problem with the manufacturing of the box cover, let's go, let's go to the manufacturing workshop to have a look."

what!
Something went wrong with the manufacture of the box lid!
What's wrong with it?

Everyone knows that the manufacturing cycle of the box cover is long and difficult to manufacture, and it is one of the few parts that have not yet been processed.

In addition, it is an important part with high quality requirements, especially the precision requirements for several mounting holes on it are extremely high.

One of the technicians thought pessimistically, it must not be the problem with the processing of those few mounting holes. Once there is a problem with these precision holes, it would be a big deal.

Very serious big thing.

Gu Zhengxin's pace was fast, and he led everyone out of the assembly workshop and quickly walked towards the manufacturing workshop.

At this moment, he had an urge to scold someone.

Commander Yang and Commander Luo will go to Hongqi Factory tomorrow to inspect the progress of diesel engine manufacturing, and they are also scheduled to start the middle assembly of the first diesel engine the day after tomorrow. At this time, such a problem unexpectedly occurs.

A group of people soon entered the manufacturing workshop.

From a distance, I saw a large group of people surrounded there, including workers, managers, technicians, and leaders of the manufacturing workshop.

There is an imported precision three-coordinate vertical CNC machining center. In 1995, there were only a handful of enterprises in China that could have such machine tools.

This is also the key equipment of Hongqi Factory, and it is the "only child" equipment.

What is an "only child" device?

It is the only one in the whole factory, unique.

Because the precision is very high, and it is a numerical control equipment, if drilling, boring, milling, etc. are required for some high precision requirements, it is generally processed on this equipment.

At this moment, there are many people around it.

Next to this equipment, there are several parts trays, each with a diesel engine cover on it, a total of six.

Three of them have apparently been processed, and are placed on the other side, and there are three more to be processed.

Gu Zhengxin walked in with a group of people, and asked in a deep voice, "Director Wu, what exactly is going on!"

Director Wu of the processing workshop said: "Mr. Gu, there is a problem with our CNC machining center. The equipment technician is investigating. The problem is probably not small."

what!
It turned out to be a problem with this device.

Gu Zhengxin thought that there was a quality problem during the processing of the parts. It turned out that there was a problem with the equipment. He looked at the equipment technicians and hesitated to speak.

At this time, we can only wait for the results of the investigation.

Within a few minutes, the equipment supervisor said with a dejected face: "Mr. Gu, the main board of the machine tool has burned out."

Gu Zhengxin asked in disbelief: "Are you sure the motherboard is burned?"

The engineer in charge replied affirmatively: "We are sure, and the situation will be clearer when we remove the motherboard."

Hearing this, Gu Zhengxin's heart gradually sank.

After looking at this machine tool, and then at the three parts to be processed, I suddenly felt very irritable. At this time, such a problem unexpectedly occurred.

The main board of the machine tool was quickly dismantled, and the equipment supervisor looked carefully, then pointed to one of the obviously burnt-black spots and said, "Mr. Gu, look, it's obvious that the industrial control chip on the main board is broken. A motherboard is no longer usable."

If the motherboard cannot be used, the machine tool cannot work.

The machine tool cannot work, and the remaining three box covers cannot be processed. Without the box covers, the diesel engine cannot be assembled.

The problem is serious!
Director Wu of the processing workshop obviously fully realized the seriousness of the problem, and immediately asked loudly: "Then can this motherboard be repaired?"

If it can be repaired, even if it takes two or three days, or even three or five days, it is acceptable. If it cannot be repaired and the machine tool cannot be used, then...
I just didn't dare to think about it.

The first ship has been built on the berth, waiting for the diesel engine?

The equipment supervisor looked helpless, and replied: "Director Wu, this is imported equipment, and the main board is also original. We can't do anything to repair it."

It can't be repaired!
The atmosphere suddenly became heavy.

Gu Zhengxin's face was a little gloomy, and he asked very seriously: "Contact the agent of the imported machine tool, and ask them to find a way, and the speed must be fast."

The supervisor in charge of equipment said: "Okay, we will contact you immediately."

During this period, domestic imported machine tool equipment was basically imported by agents, and agents were always contacted if there were any problems.

The supervisor in charge of equipment left, in a hurry, he needed to make some phone calls.

Director Wu of the workshop asked for instructions: "Mr. Gu, there are three box covers that have been processed, whether to go to the next process, and the remaining three unprocessed ones are waiting here for the time being."

"can."

Gu Zhengxin replied.

After this process, the box cover only needs to go through two relatively simple processes to complete the processing. It can be inspected and put into storage, and then the final assembly can be carried out in the final assembly workshop.

There are three tank covers, at least three diesel engines can not lack this part, which is better than none at all.

What about the remaining three box covers that have not yet been processed?

For a while, Gu Zhengxin didn't dare to make a decision easily. He needed a meeting, and everyone could discuss it collectively before making a decision.

Of course, Yang Fan and Commander Luo didn't know what happened at the Hongqi factory. They were preparing to go to the Hongqi factory to see the general assembly of the first batch of diesel engines and the manufacturing of various parts of the subsequent batches of diesel engines.

The air tickets of Yang Fan and the three of them had already been bought, and they packed their luggage and prepared to leave. Early in the morning, Li Zhengjun and Han Jiang met at Yang Fan's office.

Everyone is ready, there are three people including Yang Fan, and they can set off.

Raising his hand to check the time, Yang Fan said loudly: "It's almost time, let's go to the airport."

Yang Fan walked in front, followed by Li Zhengjun and Han Jiang, and got into the car in front of the office building. The trolley had already prepared the car early.

Riding in the car, on the way to the airport, Han Jiang said: "The Hongqi factory is really good. The first batch of diesel engines is about to start assembly."

Last time, he accompanied Yang Fan to the Hongqi factory. At that time, the Hongqi factory had not yet started the production and manufacturing of the parts of this batch of diesel engines, and was still undergoing a 400-hour long-term test run of the first diesel engine.

How long has it been? The first batch of four large diesel engines will start assembly in less than a year. This speed is not bad.

Yang Fan reminded with a smile: "The speed of Hongqi Factory is really good, but the speed of Dongjiang Shipyard is not slow, and the installation of some power systems will begin in one or two months."

According to the construction process, before the main section is closed, some large-scale equipment needs to be installed in place one after another. After the main section is closed, it is very inconvenient to install large-scale equipment, and even some large-scale equipment cannot be installed anymore.

Li Zhengjun said: "That's true, the speed of Dongjiang Shipyard is faster."

The atmosphere was relaxed, and the three chatted like this before heading to Donghai International Airport by car.

Compared to Yang Fan's relaxation, Gu Zhengxin couldn't relax at all. On the contrary, he was under enormous pressure.

This "only child" equipment failed, the industrial control chip on the motherboard was broken, and the equipment could no longer be used. As a result, there were still three pieces of the box cover that could not be processed, which may result in the fourth diesel engine having no box cover to assemble.

The Hongqi factory quickly contacted the agent, and their response was relatively fast, and it didn't take long to contact the manufacturer of the equipment.

The manufacturer replied that it may take at least 20 days to send someone to repair it, and asked why it took so long.

They replied that they do not have after-sales service agencies in our country for the time being, and it takes time for their after-sales maintenance personnel to obtain visas, and 20 days is the ideal situation.

Then you can't wait for the other party's after-sales personnel to come over, you have to find another way.

What Gu Zhengxin thought was to ask for help from his brother unit. After making a few calls, his mood became even worse.

These brother units either do not have such CNC equipment, or they cannot process such a large-sized box cover.

what should we do?

Gu Zhengxin was still in the office, frowning slightly, still thinking of a way.

After making another phone call, he finally gave up the idea of ​​asking his brother's unit for help in processing. He thought in his heart, it seems that he can only rely on himself.

There are still three pieces of box covers left, as long as one can be processed to pass, it will be considered a success, at least it can guarantee the assembly of the fourth diesel engine.

Three guarantees and one should have a certain degree of certainty.

After making up his mind, Gu Zhengxin personally organized a meeting with relevant personnel, came up with a set of processing plans, and selected the most experienced masters. If there is no large-scale CNC equipment, ordinary equipment will be used.

Inside the manufacturing workshop.

There were three unprocessed box covers next to a piece of ordinary processing equipment, surrounded by many people, Gu Zhengxin, director Wu of the manufacturing workshop, several managers, several technicians and so on.

The first box cover was finally lifted onto the workbench of this ordinary machine tool. The workpiece was carefully fixed, the knife was aligned, and after confirming that it was correct, the experienced worker started processing.

The scene suddenly fell silent.

Some people were inexplicably nervous, praying, God bless, must succeed, must succeed!
The worker didn't dare to be careless and concentrated on it. Such high-precision processing was also a great challenge for him, and he was not fully sure.

He also knew that at this critical moment, he had to go.

If even he is too timid to go up, then others will be even worse, because he is one of the most skilled and experienced workers in the entire manufacturing workshop.

The passage of 1 minute and 1 minute seemed very long.

Finally, several precision holes of the box cover were all processed. Some people heaved a long sigh of relief, and more people thought in their hearts, how is the processing quality?

Is the processing qualified?

That's all for today's update, thank you all.
