All kinds of machinery have their own uses, and the right parts are made with the right machinery, which not only saves money but also saves trouble. So this special tool, Gu Fei started the wire cutting machine to process and manufacture.

Wire cutting is actually a kind of CNC machine tool, which has a set in cutting. However, in the eyes of many people, its biggest feature is that it is dirty, and it is horribly dirty.

Lin Chunhui glanced at it from a distance, and simply didn't follow. Gu Fei put the materials on and fixed them, compiled a simple program, started the machine and observed for a while before running back.

Luo Xiuqiao was immersed in debugging the machine tool in the No. 1 machining center, while Lin Chunhui was watching with interest with his neck stretched.

Gu Fei shook his head. He retracted his gaze and glanced at Luo Xiuqiao's computer screen, and was stunned.

He was familiar with the parts that were open on the computer. Gu Fei took a closer look and found that it was the hinge base designed by Anjing. That is, on that day, he took it out to prove to the three of them that testing is also a troublesome part.

After a while, Lin Chunhui took a glass of water in one hand and a mobile phone in the other, and walked over.

He glanced twice outside the workshop, and after a few words of the desertion of the factory, he sat down on the chair next to him. He let out a long sigh of relief and said to Gu Fei, "Gu Fei, she will come over here in a while." ”

The eyes in Lin Chunhui's mouth are naturally Anjing.

Gu Fei nodded. He glanced outside a few times and said with a smile: "Come on, after working at school for so long, it's not a bad thing to take the time to come out and walk around." ”

"Yes, what about Pang Ansheng? Won't he come? Gu Fei asked again.

"This, I didn't say it just now."

Lin Chunhui pursed his mouth and joked: "But as long as Pang Ansheng has his bones, don't come out to squeeze the bus." What should I do if I accidentally squeeze the steel needle out of my body? ”

The two of them thought about the situation carefully, and they couldn't help but shudder.

The topic was obviously not suitable for further conversation, and the two paused at the right time.

Lin Chunhui leaned lazily on the backrest. He poured a mouthful of white water boldly, looked at Luo Xiuqiao, who was busy on the machine tool not far away, and talked about the topics that they senior students talked about most often during this time.

"Gu Fei, have you ever thought about what you will do after graduation? Is it to stay in the city or to go home? ”

Gu Fei was stunned.

During this time, he was always busy with work or design competitions, and rarely contacted other classmates, and basically did not talk about this topic with others.

He stopped, his eyes wandering, and it took him a long time to gather focus. He smiled and said word by word: "The future! If you want to make some money, try your hand at starting your own business in this city. ”

"Ambitious!" Lin Chunhui nodded, reached out and patted Gu Fei's shoulder heavily. He was not surprised by Gu Fei's choice. If he also had Gu Fei's ability, he would basically choose to do so.

"What about you?" Gu Fei asked Lin Chunhui rhetorically.

"I'm ......" Lin Chunhui dragged a long tail note, and a sweet smile inadvertently appeared on his face. He replied without asking, "Jing'er and I decided to get married as soon as we graduated. ”

Gu Fei was stunned for a moment, and after he gave a thumbs up, he laughed and said, "What?" Do you want to challenge the topic of 'falling out of love together after graduation' on the Internet? ”

Lin Chunhui shook his head and said with a faint smile: "I'm not so bored." ”

He explained: "It is said that you should start a family first and then start a business, and a good girl should be caught first." Qing'er is a good girl and deserves to be cherished. ”

Gu Fei couldn't help but be stunned again, and nodded thoughtfully after half a sound.

It took him a while before he joked, "Okay, remember to let me know when you two get married." But ......"

"But the money may not be so thick."

Lin Chunhui didn't care, he smiled and nodded. The two chatted a few more words before turning the conversation back to the work at hand.

"What is he doing?" Lin Chunhui asked curiously.

Gu Fei turned his head to look, and saw Luo Xiuqiao slowly lowering the spindle with a handwheel in one hand, and holding a stick in the other hand to continuously test the knives on the spindle on a flat surface.

"Oh." Gu Fei recognized it at a glance and said with a smile: "He is setting the tool length compensation of the machining center, which is the knife in layman's terms." ”

Lin Chunhui suddenly realized and asked casually: "Isn't there an instrument called an automatic tool setting instrument?" Isn't that better? ”

Gu Fei shook his head and said, "The automatic knife setter is not as easy to use as you think. It can even be said that it is also a kind of auxiliary tool for chicken ribs. ”

"Huh? That sounds like a tall name. Lin Chunhui was a little unconvinced.

Gu Fei was not surprised. A lot of people can only imagine something through their names, and they don't really use it. So some plausible results were drawn, and Gu Fei understood it very well.

He thought for a moment and explained.

"The method of tool alignment is actually a variety of tools of different lengths, and when their tips are in the same plane, the height of the spindle drop is recorded. These different heights are fed into the machine parameters. ”

"When workers manually set the tool, be careful, and easily ensure that the tool setting error is within 1 to 2 wires. With the automatic tool setter, at least this error can not be guaranteed. It's just that the error is not high, it is slow and stupid to start the knife. ”

"Because the process of automatic tool setting is actually a program. As long as it is a program, it represents a machine and a rigidity.

Don't look at CNC machining, the tool or machine is very flexible, jumping up and down and flying all kinds of flawless. In fact, it is also a kind of alternative rigidity.

For example, from roughing to finishing, ten knives work in a certain place at the same time. If the tool is broken during rough machining, then you can see that the next nine knives will be like a fool, one by one in the same place, and then folded, without exception. ”

"It's the same with an automatic tool setter. Because a machine is a machine, it is not a human eye.

When manually setting the tool, if you see that the tool is still far away, you can speed up and lower the spindle. In the case of automatic tool setting, the instrument does not know how big and long the tool on the spindle is. Therefore, most tool setters begin to slow down when the tool is high or far away, and approach slowly so as not to damage the tool setter.

Those machining centers with high and large strokes can use an automatic tool setter to pair a knife, which is enough to make people jump in a hurry. Even a dozen knives are enough to make any boss want to beat it to death and dismantle it directly. ”

"Of course, the above is talking about universal machine tools.

In the case of special-purpose machines, those that are specifically designed to manufacture a certain part. From creation to scrapping, it only makes one or a few products, and the automatic tool setter is much easier to use. Because everything is already in mind when the machine is designed. Even the diameter and length of each tool have clear requirements. Naturally, the role of the automatic tool setter is greatly increased. ”

When Gu Fei said this, Lin Chunhui was dizzy when he heard it, so he had to hang his head and feel dejected.
