A copy machine tool is a semi-automatic machine tool that controls the trajectory of a tool or workpiece according to a model or mold.

Because it relies on the semi-automatic profiling function, it can handle complex workpieces and the machining accuracy is higher than that of ordinary manual machine tools, so before the large-scale popularization of CNC machine tools, profiling machine tools have almost become the standard configuration of industrial powers.

In particular, Western countries led by the United States have developed rapidly in this field, and have successively developed three generations of hydraulically driven profiling machine tools.

In the early 60s, the United States relied on its strong talent and industrial strength to develop a four-axis hydraulic machine tool imitating a five-axis "black technology", thus suddenly throwing off the distance from the Soviet Union in terms of finishing.

As for the Soviet Union, it is not far behind in this regard, and has successively launched several good performance profiling machine tools, which are applied to weapons manufacturing, aerospace and shipbuilding industries, but due to the rigid strategic thinking of the Soviet Union, they do not pay enough attention to expensive finishing, so that they are always slower than the Americans in this regard.

But this does not mean that Soviet machine tools are not good enough.

For example, this copy machine tool produced by the Minsk Machinery and Equipment Manufacturing Plant, which was pulled back to the factory and assembled by Meng Jianye and Liang Mingqiu overnight, with the main task of processing the complex curved surface of the marine propeller, can be called the master of the Soviet Union's machine tool technology in the 60s.

Because the machine tool not only has the hydraulic drive device commonly used on the profiling machine tool, but also integrates a set of photoelectric integrated system on this basis, which is used to control the cutter head driven by the hydraulic system, and finish the complex surface according to the graphic code on the special cardboard on one side.

If a professional who studies CNC machine tools sees this scene, he will definitely be surprised, where is this NM copy machine tool, is it clearly the original CNC machine tool?

Yes, the machine tool produced by the Minsk Mechanical Plant is indeed a CNC machine tool, but in the fifties and sixties, the concept of the word "CNC" was not perfect, so the Soviets classified this application of photoelectric control technology and paper coding machine tools into the ranks of profiling machine tools.

Meng Jianye doesn't care about how to divide it, and he doesn't even care about how this machine tool came to China and how it settled in the excellent factory, what he values is only the machine tool itself.

Because the Soviets left a lot of room for transformation and improvement when designing and manufacturing this machine tool, especially the optoelectronic integrated system, which was designed to be very open, which also caused the fragile tube components inside to be easily damaged.

Obviously, the Soviet Union at that time also treated this machine tool as an experimental product, and aiding China naturally also had the meaning of the guinea pig doing the test.

This kind of open design may have been a disaster for the fragile components at the time, but it was a great blessing for Meng Jianye, a naval house that has been immersed in technology all day long.

Because this gave him ample possibility to modify the machine tool, otherwise it would be like other machine tools in the Soviet Union, but there was no room for it, and Meng Jianye was both willing and powerless.

"If the four-axis bed is fake, we really picked up a big leak this time, I dare to guarantee that if the excellent factory knows, their people will definitely cry and faint. ”

Liang Mingqiu walked around the machine tool twice the moment the machine tool was installed, and his taciturn mouth on weekdays was like an early bird, and he was so excited that he was about to become Niu Chen's broken mouth.

"I don't think it's necessary to cry and faint, because even if they knew, what would they do? Who would use this thing? Besides, the electronic components behind this are like small light bulbs, and this is not enough, one by one is more exposed than the wild men who entered the bathhouse, and as soon as the machine is turned on, the vibration and the splashing of cutting fluid, it is estimated that the thing is not finished, and this photoelectric system will have to be scrapped. ”

Liang Mingqiu's excitement here has not passed, and Niu Chen, who installed the machine tool together, poured a basin of cold water on his face, he was right, will these machine tools be used in another way, the key is that the light spot system is too fucked, otherwise the excellent factory is not a fool, why not put such a good machine tool?

"What do you mean that you have to scrap before you finish processing? Don't you be careful? It's really not okay to add a cover, Xiaoye, do you say this is the reason?"

Liang Mingqiu doesn't care about anything, even if he is about to be expelled by Shen Damin, he is silent, but once he talks about machine tools, it is the same as meeting a baby, not only can he talk to you for three days and three nights, but even his mild temper is agitated.

Meng Jianye naturally nodded to the brother who was sleeping on the top bunk: "Xiaoqiu is right, the electronic components in the back are not tight, and in the future, we will all replace them with integrated circuits in Europe or the United States, and make these four-axis machine tools into imitation five-axis, and by the way, our factory has also been addicted to building submarine propellers." ”

As soon as these words came out, Niu Chen immediately raised his hand and surrendered: "Okay, okay, Xiaoye, my old cow is in service, and the submarine propeller is returned, let's stop today, I'm afraid that even the spaceship propeller can come out if I talk about it again." ”

Liang Mingqiu didn't say anything, except for glancing at Niu Chen, he just gave Meng Jianye a simple grateful look.

Meng Jianye looked at the reaction of these two people, okay, he dared to say such a lot, the two didn't believe it at all, but think about it, submarine propeller has always been a high-end equipment in shipbuilding, because it not only shoulders the mobility of thousands of tons of behemoths, but also is one of the rare main sources of noise in the extremely concealed equipment of submarines.

Because of this, how to balance concealment and propulsion efficiency has always been a difficult problem for the shipbuilding industry.

Meng Jianye's words can be called bold words if they are said in those powerful factories, but in Endeavor Factory, a small factory that has just had the opportunity to build ordinary cruise ships, it will be a bit ridiculous and generous.

It's like a kindergarten child who threatens to go to the World Cup to mention the Chinese team to win the championship, just listen to it as a joke, and don't take it seriously.

But the problem is that Meng Jianye is not a joke.

"Hey, I said you two don't believe it, do you? Do you want to gamble?" Meng Jianye also came up.

"Bet on it, half a month's salary, don't be strained if you lose!" Niu Chen is not afraid of this kind of hard bar, not to mention Niu Chen, even Liang Mingqiu pursed his lips and snickered, thinking that this bet was worth it.

Seeing the appearance of the two of them, Meng Jianye had no illusions at all, and took out a small notebook: "Yes, yes, don't say anything, let's make a note first......"

"What kind of note?" However, before Meng Jianye could finish speaking, Liu Hao walked in with a middle-aged man with a seagull camera around his neck, making several people chuckle in their hearts at the same time, but before a few people could react, Liu Hao continued anxiously:

"If it's not important, you just wait, I'll do the machine tool photos first, Director Jiao is about to burn his eyebrows everywhere. ”
