Chapter 426 Duan Hongxuan’s strict requirements for machine tool production
Although the steel rolling mill wants to produce machine tools, they have no experience in the production of complete machines. The leaders of the steel rolling mill do not dare to send people to other companies until the official document from the ministry that specifically allows the rolling mill to produce machine tools is issued.
After learning from the experience of the machine tool manufacturer, Director Yang went to the doctor in a hurry and went to Duan Hongxuan to ask Duan Hongxuan to give him some advice!
Duan Hongxuan thought about it seriously, and then said solemnly: "Uncle Yang, several leaders, you have talked about this, so I will boldly share some of my opinions!"
Seeing Director Lin and Deputy Factory Director Lu both opening their notebooks and preparing to take notes, Duan Hongxuan twitched the corner of his mouth, organized his words, and then continued: "The machine tool I developed, for the production of the whole machine, I personally feel,
The most important thing is quality, which is also the top priority!
After the machine tools are produced, they will eventually be sold to other manufacturers for use. If the quality of the machine tools we produce is not up to standard, no matter how good the performance of our machine tools is, the manufacturers that can use the machine tools will suffer a loss every three days while using our machine tools.
If something goes wrong, it will seriously delay other people's production. Over time, this will cause serious damage to the reputation of our steel rolling mill. Gradually, people will no longer be willing to use the machine tools produced by our steel rolling mill!
Therefore, the production quality of machine tools is the top priority!
Then, the quality issues surrounding machine tools continue to expand.
The quality of the entire machine, in addition to assembly, is guaranteed by the quality of each spare part!
So by extension, if you want to ensure the quality of the whole machine, you must first ensure the quality of each spare part!
So my suggestion is that the quality inspection team is very important in the entire machine tool workshop. This team must start with the quality inspection of each spare part. Only if it is qualified can the complete machine be assembled with these spare parts.
After the whole machine is assembled, the quality of the whole machine needs to be inspected again!
People in the quality inspection team must be selfless and merciless!
The others who are responsible for technology and production are all regular configurations in the workshop, so I think I don’t need to say anything else!"
After everyone listened to Duan Hongxuan's words, Deputy Factory Director Lu hesitated for a moment, and then asked: "Classmate Duan Hongxuan, do you mean that this workshop must have a non-working group who are responsible for quality inspection?" p>
Duan Hongxuan nodded: "Yes!"
"Isn't this too wasteful?" Deputy Director Lu asked with some doubts.
"Oh?" Duan Hongxuan asked curiously: "Deputy Director Lu, who is responsible for the usual quality inspection in your factory?"
"Generally, whoever produces is responsible, and then the production team leader conducts random inspections!"
Duan Hongxuan shook his head when he heard this: "I can't say how other workshops in your factory conduct quality inspection, but the production of complete machine tools must have a dedicated quality inspection team in charge!
This is not a waste of manpower, this is a guarantee and responsibility for the quality of the products you produce!"
"Okay, since you insist, we will seriously consider it!
But starting quality inspection from the parts is a bit too much? A bit redundant? Is it necessary to be so strict?" Deputy Director Lu asked again.
Duan Hongxuan sighed helplessly, and then explained: "This kind of strict quality inspection is, on the one hand, responsible for the quality of the products we produce, and on the other hand, it is also a kind of savings!
Think about it, if we don’t conduct quality inspection of spare parts, but let the production workers inspect them themselves.
If, I mean if, a worker has selfish motives, or he is careless, and the size of the parts produced is a little off, and after we assemble the whole machine, we suddenly find that there is something wrong with the assembled machine tool, or
It's not accurate enough.
You know, for a machine tool, accuracy is the most important technical indicator. If the accuracy of the machine tool does not meet the design requirements, then the machine tool is not a qualified product. What should I do at this time? Check it! p>
After checking again and again, but no problem can be found, what should we do? This machine tool is a substandard product and cannot be sold out of the factory. Doesn’t it mean it is a scrap product?
Isn’t it a huge waste to scrap the entire machine tool just because of one part?
If we could check and exclude unqualified parts in advance, wouldn't this kind of waste be avoided?"
When everyone heard this, they suddenly realized, especially Deputy Factory Director Lu, who sighed: "So that's it! I understand!
Alas! This means that you have no experience in complete machine production!
Some workshops in our factory only process some parts according to the production tasks assigned by superiors, and they never involve any problems with the whole machine!
If a component is qualified, it will be qualified. If it is not qualified, it will be over. When you tell me about the production of the whole machine, I completely understand it!
From this point of view, it is necessary to conduct quality inspection starting from every spare part!"
Director Yang also expressed his gratitude to Duan Hongxuan with excitement: "Hongxuan, thank you for your suggestion!
Look, you said you didn’t understand, but now you get to the point as soon as you open your mouth!
Without your reminder, we would have followed our factory's previous production experience and waited until the entire machine tool was assembled before inspecting it. If there were indeed parts of the wrong size mixed in, it would have been a huge waste!
Please continue talking and see if there is anything else that needs attention!"
Duan Hongxuan suddenly thought of a question, so he asked Factory Director Yang: "Uncle Yang, when our factory usually produces some parts, does it follow standardized procedures?"
"Standardized procedure?" Director Yang was curious after hearing this: "What specific standardized procedure are you talking about?"
Duan Hongxuan recalled it carefully, and then he roughly remembered that this year is only 1961, and it seems that the country will not officially issue specific implementation standards for industrial standardization until next year!
So Duan Hongxuan explained like Factory Manager Yang: "Let me give you an example of so-called standardization!
Just like guns and bullets, if a unified standard is used, as long as it is the same model of firearm, no matter who produces it, he can use the same caliber of bullets!
This chapter is not over yet, please click on the next page to continue reading!
And conversely, no matter who produces the bullet, as long as it is matched with the firearm, any bullet can be used on any firearm without jamming or other problems!"
After hearing this, Director Yang nodded and said: "When you say that, I probably understand!
What do you mean, if our steel rolling mill produces machine tools, we must also adopt standardization?"
"Yes, Uncle Yang, machine tool production must use standardized production standards and procedures. In this way, during the assembly process, as long as the parts are of the same type, they can be assembled with any other parts!
And there is another advantage. During the later maintenance, if any parts on the machine tool wear out, it is very convenient for us to replace them. As long as they are produced by the machine tool workshop, we can replace them for them.
Instead of having to go out of your way to help them produce a new part!
If the production of all spare parts is strictly standardized, the quality and accuracy of the assembled machine will be easier to control!
Therefore, I suggest that the technical department of our factory must introduce standardized procedures into the subsequent design process of machine tool production processes. This is also a very important factor in ensuring the quality and accuracy of machine tools produced in steel rolling mills! p>
The biggest performance advantage of the machine tool I developed is its machining accuracy. If there is no machining accuracy, or the machining accuracy fails to meet the design requirements, then this machine tool will be useless!
In view of this, Uncle Yang, I suggest that the skills of the workers in the machine tool production workshop should not be lower than level four workers, of course it is better to have higher skills!
Uncle Yang, don’t think my requirements are high. In the past, your factory only produced and processed some spare parts, which is nothing!
But the most important indicator of the performance of a machine tool is its machining accuracy.
Our neighbor, little devil, when assembling some machines, the assembly standards and requirements are very high. How high are they? Let me give you an example!
When they assemble the whole machine, they have strict requirements on how many turns each screw needs to be tightened, and some screws are even as strict as 1/4 or even 1/8 turns. It is under this strict requirement that other people's machines
Including many machine tools, the processing accuracy is very high!
A machine tool, from the strict standard requirements of spare parts to the strict requirements of the entire assembly process, can make the entire machine tool reach high-precision processing standards!"
"Hiss!" Director Yang and others took a breath of cold air when they heard the example Duan Hongxuan gave. Deputy Director Lu asked in surprise: "Classmate Duan Hongxuan, are you telling the truth? Are they really so strict?
?"
"Of course, otherwise, why can other people's machine tools be so precise? It's because of their high standards and requirements!
Although we paid for many of the advanced machine tools we imported, we cannot move a single screw on them. Otherwise, if something goes wrong with the machine tools, the manufacturer will not be responsible at all!
For many high-precision machine tools, often just because you may move one screw slightly, it will affect the processing accuracy of the entire machine tool!"
"Isn't this too strict?" Deputy Factory Director Lu was really frightened now, "Can our factory handle such strict standards?"
As soon as Duan Hongxuan heard what Deputy Factory Director Lu said, he immediately replied: "If the steel rolling plant doesn't work, then find another plant!"
Duan Hongxuan's words could be said to be rude, and he didn't save any face for Deputy Director Lu, which immediately made Deputy Director Lu feel a little embarrassed!
When Professor Wu saw it, he quickly scolded Duan Hongxuan: "Hongxuan, why are you talking to Deputy Director Lu! Apologize quickly!"
Duan Hongxuan looked at Deputy Director Lu, who was looking embarrassed, and said, "Deputy Director Lu, what I said just now is not nice. Don't take it to heart. I am dealing with the problem and not the person!
What I just said was not only talking about you, but also for Uncle Yang!
You are not alone in thinking this way. I think including Uncle Yang, your entire steel rolling mill, from the director to the workers, probably all have this idea!
If this ideological concept does not change, I really feel that your rolling mill is really not suitable for producing the machine tools I developed!"
