Great Power Ship

Chapter 41

Wen Dawei was a little surprised. You must know that the gas generator valve in the ion nitriding furnace is one of the most critical components in the furnace. Its main function is to be responsible for the gas supply and the injection of ammonia and hydrogen. There are extremely strong requirements for passability, so the requirements for machining accuracy are extremely high.

Let alone now, even after decades, not just any factory will be able to process it.

However, at this moment, Zheng Dexing told Wen Dawei with certainty that their machine shop had no problem processing such parts, and he could even do it himself.

Although Wen Dawei himself is not in the machining workshop, he has heard a little bit about this workshop. The equipment used to build the factory back then was transferred from various factories in Northeast and East China, and a large part of it was old equipment from the Soviet aid construction period.

Even some of the newer ones are imitated by relying on those Soviet equipment.

These equipments were not bad in the 60s, but by the 80s when automation and numerical control had been popularized around the world, these equipments in Lidong Factory had obviously aged obviously with the naked eye.

As for the gas generating valve that Wen Dawei needs, at least it can be made by four-axis or six-axis CNC. Obviously, Lidong Factory does not have such equipment at all now, so how to make it?
Wen Dawei couldn't help being a little curious, especially the equipment that Zheng Dexing and Qin Xiaoqiong mentioned repeatedly just now. It stands to reason that there is such a magic weapon, so it is impossible for him, a child of the factory, to not know about it?

So he asked tentatively: "I remember that our factory doesn't have CNC?"

"That's the CNC on our workstation is just a decoration!"

Before she finished speaking, Qin Xiaoqiong came out of the kitchen, took a kettle, and took out a few water cups from the side cabinet, put tea foam on them, made two cups of tea and put them in front of Wen Dawei and Zheng Dexing: "It can be used, But delicate, those old masters find it troublesome, basically they don't know how to do it, and if they don't move, the apprentices under him don't bother to touch it.

Over time, it has become a special attraction for superiors to inspect, after all, the name of CNC machine tools is still very bluffing, and our task is to ensure that this machine tool looks good..."

Qin Xiaoqiong's tone was full of disdain and sarcasm, while Wen Dawei was dumbfounded, thinking that there was such a magical operation, but before he could react, Zheng Dexing took a sip of the hot tea, then put down the cup and added : "In my opinion, that equipment is still in good condition.

I have operated it once before when I tested the machine. The overall accuracy and efficiency are much better than the ordinary machine tools in the workshop, but the numerical control is too complicated, and the controller is somewhat insufficient, which requires special attention in operation. There is no ordinary machine tool. The machine tool is so relaxing, so the master craftsmen don't like it very much. "

"That's the second thing. The key point is that the foundation of the machine tool is too old..." Qin Xiaoqiong took over the conversation: "FS-355 vertical milling machine, a product of Germany in the 40s, was aided in the 50s, didn't the old masters say it? , the obsolete goods from the brother factory, added a numerical control name and pushed it to us..."

"Then I know..." At this point, Wen Dawei knew what the equipment the couple were talking about, so he asked without waiting for Qin Xiaoqiong to finish speaking: "Are you talking about the 78 from a certain factory in Northeast China? Give us a congratulatory gift for the 5th anniversary of the establishment of the factory?"

"That's right, it's the CNC bed!" Zheng Dexing nodded.

Wen Dawei smiled noncommittally: "It's just a 355A digital punching control machine added to the FS-213 vertical milling machine, which is far from the current mainstream CNC machine tools in the world, but it can be regarded as CNC in detail. But it's a little behind!"

What Wen Dawei said was true. The Lidong factory was indeed a CNC machine tool that was presented by a factory in Northeast China as a congratulatory gift for the 5th anniversary of its establishment. However, it was different from the traditional CNC machine tool. The CNC mechanism of the XK410 vertical CNC milling machine is really primitive.

The reason for this is mainly because the 213A CNC machine of this machine tool adopts the most primitive paper tape hole input method to realize the machine tool control.

That is to use a special paper tape to list different hole combinations on it, and then use the photoelectric circuit in the controller to identify the holes, so as to realize the automatic control of the machine tool.

That is to say, the hole combination of the paper tape is the numerical control program, and the controller that interprets the hole combination is the computer.

Although this type of structure realizes CNC automation, the programming of the CNC program is too simple and cannot guarantee the accuracy of the machine tool, so it is quickly replaced by a more capable CNC machine tool.

Regardless of whether the XK410 vertical CNC milling machine is backward or not, it is indeed a treasure for Lidong Factory. No one can shake the brand of a CNC machine tool.

No way, CNC machine tools are still rare in China at present, not to mention high-end imported CNC machine tools, even XK410 vertical CNC milling machines, which are not advanced domestic CNC machines, are not available to everyone.

Lidong factory has such a machine, just like the wealthy people who can own bicycles and small watches nowadays, it is a symbol of strength and status.

Not to mention anything else, there are so many factories in Guizhou, Lidong Factory is the only one with CNC machine tools, even in the whole province, there are only a handful of factories equipped with CNC machine tools.

With such a brand name, it is not surprising that this XK410 vertical CNC milling machine is valued by the factory, but the degree of attention seems a bit crooked...

After knowing the cause and effect, Wen Dawei couldn't help sighing: "As Brother Zheng said, this XK410 vertical CNC milling machine is still usable, but the matching 213A CNC machine is a bit stretched, otherwise the XK410 vertical CNC milling machine can really work." Save a lot of things!"

As soon as these words came out, Wen Dawei didn't feel anything, but Zheng Dexing and Qin Xiaoqiong looked at each other in surprise, and then Zheng Dexing asked in surprise, "Brother Wen knows machine tools?"

"I've read some materials, but I don't know much." Wen Dawei smiled modestly.

But the next moment, his smile froze on his face. Before Wen Dawei finished speaking, Zheng Dexing stood up immediately, and immediately came to the head of the bed, and pulled the white curtain on the entire wall beside the bed, The densely packed whole side of the book is exposed.

Zheng Dexing didn't speak, he rummaged through the pile of books, found a book and took out a notebook from the other side, then returned to Wen Dawei with a smile, and handed the book over: "I am also Research 213A CNC machine, but some lines are too complicated, I always don’t understand, I have written some experience in my notes, since you have also known 213A CNC machine, please help me to see if there is something I don’t understand right……"

Wen Dawei held the book and notes for a long time before recovering, then curiously opened Zheng Dexing's notes, and the beautiful Leifeng script and exquisite circuit diagram came into view, and then turned a few pages, Wen Dawei couldn't help but wrinkled Frowning, Zheng Dexing couldn't help asking: "What's wrong?"

Wen Dawei shook his head: "Your idea of ​​improvement is correct, but the circuit processing is complicated!"
