Super manufacturing empire

"What the hell is that, go to work!" Yun Kai ignored Hu Cheng's mutter.

It seems that I am scolding myself.

Hu Chengcheng himself is a master. He has no girlfriend or wife. He learned from him. He called him to learn from his wife. Didn't he criticize himself as a Japanese?

What a pain!

Yang Wei felt even more painful while watching.

Thinking that when he was a master a few days ago, none of these grandsons paid attention to him, and Yun Kai didn't even dare to talk about these goods anyway, and his heart was even more angry.

"Complete the three-dimensional modeling work of these products as soon as possible, there is no problem, Yang Gong?" After Hu Cheng left, Yun Kai calmly asked Yang Wei, who was still ugly.The work of sculpting these products with curved surfaces and inclined surfaces is not complicated, but in these two days he has to hurry up to design the tooling for the previous process of Lao Maozi's list.

If someone can help him share the workload that takes a lot of time, why not do it?

"There is a problem! When you came back to do these tasks, my uncle gave the money, and these things should be done by you! Do we have a good relationship? Why should I help you?" The grandson Yun Kai actually gave an order. Talking to yourself, really making yourself a subordinate?

"That's fine, no problem, you should arrange the business of other customers in this factory..." Yun Kai nodded indifferently, too lazy to talk to him anymore.

I came back by myself, just to solve the aerospace group's replenishment, the others have nothing to do with me!

Although the processing of this batch of goods is difficult and the accuracy requirements are high, most of them are finished later, especially most of the car workpieces have to enter the machining center to mill some cavities for assembling other accessories. This further increases the difficulty of processing.

However, as long as you are a master who has been working on a single product for several years, be careful and measure several times, no problems will arise.

"Master, don’t you work the night shift at night? Why don’t you go back to rest?" The three processing centers stopped two, all waiting for the aerospace replenishment products, and another domestic Taiwan jade precision machine 850 processing The center is milling the driving cam on the car. This is a mass-processed part. As long as there is no problem with the tool and the equipment, the apprentice only needs to clamp and disassemble the parts.

"I'll wait for you to get the program out and adjust the machine before leaving." Yun Kai said while watching Hu Cheng's rough set of the tail wing and the alignment.

Last night, he came to drew the 3D graphics needed for the work that the machining center needs to do today. The rough machining of these tail fins is only 2D plane processing, and there is no need for three-axis linkage 3D surface processing. Hu Cheng is fully competent.

"Yun Kai, come with me to the office..." Yun Kai was checking the parameters of the processing program compiled by Hu Cheng, and Wu Feng came over and said to Yun Kai.

"Wait a minute." Yun Kai frowned and said to Wu Feng.

Could it be that Yang Wei ran to sue himself for the evil?The most annoying thing is the occurrence of such a shit. If possible, Yun Kai would like to ask Wu Feng to tell the guy to leave, and then let him come back after he leaves.

"President Chen and Mr. Deng are here, so let's put your hands on the matter first..." Wu Feng's expression was anxious.

Yun Kai had no choice but to follow Wu Feng to his office first.

"Xiaoyun, this is how things are. The General Armament Department has changed the requirements and asked us to deliver the finished product of the six-engine experimental cruise on July 15th. There are no problems with other parts. Now we are waiting for your connection. The flange, the air rudder, and the air rudder shaft. Can you make six sets of them before Wednesday next week, that is, before July 8?" Deng Dongquan directly stated the new requirements of aerospace.

Today is June 28th. The processing cycle of this air rudder, that is, the tail wing, is originally very long. The machining center is rough milled, then the datum is ground by a surface grinder, and then the weight reduction cavity in the middle is processed by wire cutting. After artificial aging , And then use the machining center for finishing, you have to go through the final fitter and fine grinding......

The process is very long and the time is very tight...

"Mr. Deng, this machining center requires six hours for rough machining, and the process is still relatively long. Both the grinder and wire cutting have to be outsourced, and the finishing machining center takes eight hours... I can't guarantee the progress... Yun Kai calculated for a while and shook his head directly.

For things that cannot be guaranteed, it is best not to guarantee it now, otherwise, if you cannot hand over the product later, it will not only cause trouble to the other party, but also cause great confusion to yourself.

"If your outsourcing processing can be controlled and the process can be connected in the first time, is there a problem?" Deng Dongquan frowned and asked.

"Xiaoyun, don't worry about this. I have already told them about the outsourcing. When we are about to finish processing, their equipment will stop and wait for our air rudder, grinder, and wire cutting... …" Wu Feng said to Yun Kai on the side.

Now doing this work, the consideration is not about cost, but time.

"Is there any problem now? We must deliver some of them first, otherwise..." Deng Dongquan and Chen Shengli both stared at Yun Kai expectantly.

They also know that it is difficult and stressful to complete this in such a short time.

However, if they are not delivered within the time set by the General Armament Department, the consequences are unbearable, especially for the new type of cruise missile used for testing. It is related to whether it is going to be mass-produced or has to continue to be improved.

At present, not only the situation on the Diaoyu Islands is very tense, but the situation in the South China Sea is also very tense. Otherwise, their group company specializing in the production of civilian rockets and export-type short-range missiles will not have so many military missile production tasks in recent years.

Most of them are medium and short range...

This is a political task!

"Well, I'll stop the machining center for batch parts right away. Only if two of them perform rough machining together can they enter the next process tomorrow..." Yun Kai sighed.

"Well, you go to arrange immediately, other products, no matter how nervous you are, you will give way to this batch of products first..." Wu Feng said to Yunkai.

He is showing to Chen Shengli and Deng Dongquan how much he values ​​this!

"Xiao Hu, the cam on Sun Yue's 850 stopped first. Free up the equipment and work on the tail wing. You must finish six pieces before two o'clock tomorrow afternoon and enter the next process..." Here at the machining center, do some Hu Cheng was barely capable of rough processing, and Yun Kai had to guard the night, but during the day Hu Cheng could only take charge.

He wanted Yang Wei to be in charge of the day shift, but everyone said that Yun Kai took Wu Feng's money and it had nothing to do with him...

How dare he let Yang Wei be responsible for this?

In the unlikely event that something went wrong again, he couldn't find a place to cry.

Yang Wei will definitely not admit that the craft he chose is wrong!If it is processed according to the original process, another batch of waste products must be produced.The overall thickness of the board is more than 20 millimeters. At the end of the processing, only a few parts are more than ten millimeters thick except for the connection. The thickness of 50% of the area is only 4 millimeters. The tapered surfaces on both sides are used for rectification and adjustment during flight. The thinnest part of the flight speed and direction is only two millimeters thick!

For such parts, in the final finishing process, in addition to high-speed milling with a speed of five to six thousand revolutions, ultra-precision machining of the internal cutting of the grains is carried out. Otherwise, excessive cutting force will be generated, and the rigid parts will be in the conventional The theoretical maximum speed can only reach 12,000 in the processing of the domestic machining center, because the chip force is too large, resulting in cutting vibration (the periodic beating of the tool, workpiece or equipment makes the workpiece surface streak or cloth-like traces , As serious as the kind of fine small waves produced by the breeze blowing over the calm water surface), so that the entire workpiece is considered to be too large and scrapped!

For the final finishing, the precision four-axis machining center with the highest speed of Japan Mazak that can reach 30,000 rpm is used for precision machining with repeated amount of knives, which can only minimize the deformation of thin-walled parts, rather than no deformation. .

"Master, this doesn't seem to work, right?" This Hu Cheng here has been clamped, and now he is preparing to load the knife into the tool magazine...

"What?" Yun Kai frowned.

"The cam has been dragged for half a month, and it took so long to complete the tooling. Yang Wei will definitely not agree..." Hu Cheng explained.

Yun Kai's brow furrowed even more severely.

This thing was cut out a month before he left. He coordinated to have left and back the previous processes, and now there is only the process of milling the shape of the machining center, which has not been finished for more than a month. ...

"How much is there?"

"It seems that there are more than 600 pieces. The skills of the programmers are really handed over by the teacher..." Hu Cheng said to Yun Kai with a smile.

"Shao Te is gloating here, Nima, why don't you remind him? You don't tell him the parameters?" Yun Kai didn't get angry, and Hu Cheng, the grandson, was good enough.

Hearing Yunkai’s words, Hu Cheng looked aggrieved: "Master, you have wronged me. When making tooling, I told him that there are ready-made design drawings in the computer. He had to say that our tooling was made six at a time. It’s a waste of time, so I have to change it to twelve pieces at a time. It took more than ten days to get the tooling ready, and he didn’t need the parameters I told him..."

Yun Kai sighed and understood what was going on.

This cam is symmetrical. The original tooling has only one row of six pieces, three left pieces, and three right pieces. After more experiments, this is the most efficient way.

A shift is twelve hours, and a piece of equipment per shift can produce at least 100 pieces, which can be completed in ten days. Now it took more than a month to make 1,400 pieces?

Thanks to Long Ziming for the great reward.
