Chapter 29 Domestic CNC Machine Tools
In the end, Yan Bing still didn't make this call, but just sighed softly. He knew that this kind of thing must be seen by both parties.

"Let's wait for a while." Yan Bing said in his heart.

Let's talk about Lin Feng.

After returning to his post in the crafts and technology room, he suddenly felt relaxed, as if he had completed a major event.

After feeling a lot more relaxed, I picked up one of the books borrowed from the archives and read it, and I was immersed in it all of a sudden, with a serious expression on my face.

Basically, I can flip through a page in one or two minutes, which is a little faster. You know, this is a professional book, not a novel or a magazine. The colleagues next to me seem to be familiar with this kind of reading speed.

The gate of Phoenix Factory.

A large truck was driving in, and a large wooden packing box about the size of half a container was fixed on its compartment.

Behind this car was a large forklift, and they drove into the factory area one after the other.

"This is a newly purchased device."

"Well, it looks like a CNC machine tool."

"Look at the spray on the packing box, this is a domestic CNC machine tool."

In 1990, there were relatively few CNC machine tools, and even fewer domestic CNC machine tools. For example, in the 406 workshop, in addition to the newly imported five-axis CNC machining center, there were two CNC lathes and one CNC milling machine.

However, Lin Feng often called these three CNC machine tools as simple CNC machine tools. Compared with the CNC machine tools in the 21st century, they are indeed a little simpler, both in terms of function and structure.

Easy CNC!
They are indeed simple numerical control, and there are not many of them. There are only three sets in the 406 workshop, and the other ordinary equipment are all the same.

Such as various types of ordinary lathes, ordinary drilling machines, ordinary milling machines, ordinary grinding machines and so on.

"The fifth CNC machine in our workshop arrived, and I saw the big truck pulling it in through the back door."

"Really, I heard that this is a domestic three-coordinate machining center."

"Wait a minute and see what it looks like."

The atmosphere in the entire process technology room became active at once. In 1990, a CNC machine tool still aroused great interest, not to mention that it was not a simple CNC machine tool, but a real CNC machine tool.

For this domestic three-coordinate CNC machining center, some people are eager, especially those craftsmen who know a little about CNC machining.

This is a great opportunity!
It would be great if I could become the supervisor technician of this CNC machine tool!

This is CNC equipment too!
Some people know that after entering the 90s, the proportion of CNC machining will gradually increase, ordinary machining will be gradually eliminated, and the future will be dominated by CNC.

CNC machining is like the rising sun in the morning, full of vigor and vitality, while ordinary machining is like the setting sun, which is infinitely better, but it is almost dusk.

Everyone no longer had extravagant expectations for the imported five-axis CNC machining center, because Lin Feng had already been appointed to be responsible for the technical services of this high-end imported CNC equipment.

As for this three-axis CNC machining center, it’s not bad either. Looking at the entire Phoenix Factory, it’s the first three-axis CNC machining center. If you can become its technician, it’s easy to get into the eyes of the leaders. Much bigger.

Maggie was very eager, and his heart was boiling again. He has been gritting his teeth and studying CNC knowledge hard these days. He feels that his level has improved relatively quickly, and he is fully confident to become the supervisor technician of this equipment.

He was the first to run to the scene.

As for Lin Feng, sitting in his seat, he wrote the NC program seriously, because the fixed plate of the torque measuring cylinder of the turboprop six engine will be machined on this imported five-axis machine.

Wu Qingwei, the production director of the workshop, specifically asked Lin Feng to explain the situation. The rough machining of this batch of fixed plates has been completed, and the finishing pattern is broken. It will take at least a week or more to make a new pattern.

The fixed plate of the torsion measuring cylinder is like a big disc, it has six lugs, and the contour surface processing of the lugs requires the use of a master model, without a master model, it is difficult for a clever woman to cook without rice.

Lin Feng is quite familiar with this part, and knows that it is a very difficult part to process, requiring a very experienced miller, and in one day, only two parts are processed.

In addition to the processing of the curved surface of the lug, there is a through hole with a diameter of 25mm in the middle of each lug, six lugs, corresponding to a total of 6 through holes.

The accuracy of these 6 through holes is very high, because they are used to fix the torque measuring cylinder.

The turboprop six engine has a rated torque, exceeding this torque may cause the engine to stop feathering in the air, which is a major accident.

Whether the torque measurement data is accurate has a lot to do with the torque measurement cylinder, and also has a relationship with the accuracy of the six holes.

Six holes with a diameter of 25mm have a diameter tolerance of only two and a half wires, and a positional tolerance of 5 wires, which is even higher than the positioning holes of the six-piston main casing last time.

"Little Lin, what's going on?"

Wu Qingwei was very concerned about these parts, so he came over in person again and asked about the writing of the NC program.

Lin Feng put down the pen in his hand, and said with a relaxed face, "No problem, we can start processing this afternoon."

Hearing this, Wu Qingwei's mood lightened.

He is stressed!
The six lugs of the fixing plate of the torsion measuring cylinder are processed, and the next process is to process the six fixing holes of the torsion measuring cylinder with a diameter of 25.

This is high-precision processing, which has extremely high technical requirements for workers, but Master Zhou, who is in charge of this process, has already asked for leave in advance because his son is getting married the day after tomorrow. Starting from the day after tomorrow, he has asked for a total of three days off.

No matter what, Master Zhou must finish this batch of work before taking a vacation. If he waits for him to finish this batch of work before starting this batch of work, it will be a waste of time.

So, Wu Qingwei hopes to start the processing of these six lugs as soon as possible, and then go through the flow, and strive to complete the processing of six precision holes with a diameter of 25mm before the day after tomorrow.

Lin Feng did not disappoint him, he was so powerful at the critical moment, and told Director Wu that the processing of parts could start in the afternoon.

Very good!
This is really good news!
Wu Qingwei's pressure suddenly eased a lot, and he even looked at Lin Feng approvingly, and said in his heart, Xiao Lin is really good, this can help me solve a big problem.

How could he know that there was still a huge surprise waiting for him.

Lin Feng reminded, "Director Wu, the next process is to process these six side torsion cylinder fixing holes."

Wu Qingwei said, "Yes, and the request is rather urgent. Master Zhou, who has been in charge of this process, will start his vacation the day after tomorrow, and his son will get married the day after tomorrow."

When someone's son gets married, no matter how urgent the workshop is, it must be approved, and there must be a little favor. State-owned enterprises are like this, and they usually talk about this favor.
