Liu Jianzhi finally dared to speak: "If you can use that equipment during the competition and still get first place, I will call you master from now on!"
What is that? It sounds very fancy, CNC machine tool! In fact, it is a joke.
If you want to perform mechanical processing, machine tools are the most basic equipment. It is precisely because of machine tools that there is an era of using machines to make machines. In the past, they were all made by hand.
The machine tool is very simple. It uses a motor to drive the workpiece to rotate, and then uses a turning tool to move back and forth to process different parts. This type of machine generally can only process cylinders. If you want more complex shapes, you have to divide the processing of the workpiece into several parts.
direction, or several axes, are continuously processed alternately.
So, is there any way to solve this problem? Then we need to use a CNC machine tool. The computer controls the turning tool operation of the machine tool, because the computer control is more precise. At the same time, several axes can be processed at the same time, which sounds very complicated.
superior.
In the 1950s and 1960s, the West began to enter the field of CNC machine tools, and China naturally had to work hard to catch up. In 1958, the first CNC machine tool in China was developed.
However, as for the quality, it is conceivable. During this period, people lacked a down-to-earth spirit, the quality of personnel was poor, the foundation was not solid, the quality of supporting parts was substandard, and various problems continued to arise. However, in China,
It developed blindly, had three ups and downs, and was finally terminated because its performance was too poor to be used for production.
It was not until the 1980s that CNC machine tools were introduced from the West and continuous research and study were carried out before qualified CNC machine tools were finally developed.
Now, what is hiding in the corner and eating dust is the first one that was produced in that era. In order to improve the processing level of the factory, the old masters of the No. 1 Machinery Factory trial-produced it. However, the processed parts are much better than those processed by hand.
The scrap rate was even higher, and it often broke down. After trying to produce the first batch, I gave up completely.
It was originally in the production workshop, but later the production workshop disliked the space occupied, so it was thrown into the maintenance workshop. Anyway, it is a maintenance workshop. To be able to repair tanks, you need to be able to repair machine tools.
Once thrown away, it lasts five years.
Everyone knows that that thing is not reliable at all. Now, Qin Zhenhua actually still fantasizes about using that CNC machine tool to participate in the factory's skills competition?
"Okay, Master Liu, this is what you said, just wait and see." Qin Zhenhua said.
"Zhenhua." Zhao Guodong frowned: "Are you sure?"
In the past few days, Qin Zhenhua has given Zhao Guodong too many surprises, but this definitely does not mean that Qin Zhenhua is omnipotent, especially this CNC machine tool. It was the hard work of the most skilled masters in the factory.
Crystal, now, Qin Zhenhua still wants to use it. Does Qin Zhenhua understand this machine?
"I'll try my best. I'll go to our data room and borrow all the information on this machine." Qin Zhenhua said.
"Humph, you are still sharpening your skills in battle. I want to see how capable you are!" Liu Jianzhi muttered and walked away, no longer talking to Qin Zhenhua. He had already discovered that Qin Zhenhua's words were not surprising.
There is no need to argue with him if he fights to the death, let's just look at the situation in the end.
Of course, a CNC machine tool requires a computer. In order to develop this CNC machine tool, it was also equipped with the most advanced computer, the DJS-130. This computer was a small multi-function computer jointly developed by various universities in the country.
After it came out, it was very popular and was quickly applied to all walks of life in China.
Now, Qin Zhenhua is squatting here, using DJS-130 to control the machine tool. It is definitely a luxury. Only a machine factory can have such a big deal. However, after repeated failures, the scrap rate of processing is high. What is it?
What's the reason?
Fortunately, no one touches the computer, and it is not even worth selling as junk. If you buy anything from the factory, it is usually scrap metal, which is easy to exchange for money. Now, this computer is still intact. Qin Zhenhua closed his eyes and recalled what he had learned
past knowledge.
There are books on this topic in my father's bookcase. If you want to be a qualified R&D personnel, you can't do it without mastering computer knowledge. If nothing else, if a tank wants to accurately hit its target, it has to start now.
There is a special tank gun sighting computer. Qin Zhenhua has been paying attention to these fields. He understands the basic structure, composition, how to operate, etc. of this computer. However, it is not that easy to let this computer control a lathe.
Fortunately, this kind of computer no longer requires input methods like paper tape. It has a keyboard, a monitor, and an operating system. However, this is still the first time Qin Zhenhua has come into contact with this thing.
This kind of computer is placed in a clean and tidy computer room in other colleagues, and even has air-conditioning equipment. Wearing shoe covers when entering and exiting is the most delicate equipment, but when it comes to our own place, it is piled up in the corner.
, compared with its other brothers and sisters, it is really terrible.
Forget it, just relying on what you learned before is definitely not enough, so you should go find a professional.
"Er Zhu, please clean this machine tool." Qin Zhenhua ordered Wang Er Zhu to work, and then he rode his bicycle straight to the factory's data room.
The data room was relatively remote. In a corner of the factory, Qin Zhenhua walked in and shouted from the high counter: "Aunt Wu, I would like to borrow all the data on the CNC machine tools developed by our factory, and also
There are programming materials for the DJS130 computer.”
After saying that, Qin Zhenhua put his apprenticeship certificate on it.
"Are you Qin Zhenhua? The one from the maintenance workshop?" At this moment, a voice sounded in my ears. The tone seemed not very friendly.
Qin Zhenhua turned around and saw a middle-aged man in his thirties, who was very tall and strong. At this time, he was looking at Qin Zhenhua with a pair of resentful eyes.
Qin Zhenhua was immediately surprised. He had been in the maintenance workshop. Apart from playing tricks on Liu Dajun and others, and causing Liu Jianzhi's brother and sister to suffer, he had never provoked anyone else. Why did this guy look like this when he saw him?
Qin Zhenhua touched his nose: "Yes, it's me. Which workshop are you from? Do you have any advice?"
"Advice? I can't even speak of advice. However, we all benefit from your advice. Our entire assembly workshop has no bonuses for the whole year because of an assembly error. These are all good things you did!"
It turned out to be for this! Qin Zhenhua immediately reacted: "Isn't that what our master Liu Jianzhi discovered? What does it have to do with me? I'm just an apprentice worker."
