When will I have a long tassel?

"Danji, Changji, and Qingji have all set their sights on the market for automotive-specific machine tools. However, according to what we know, their current research and development ideas are still focused on traditional boring and milling machines and machining centers, and they have not considered developing special-purpose machine tools. Station machine tools.

"Initially, the R\u0026D ideas proposed by our technical department were also the same. Because the development of multi-station machine tools was too difficult, we lacked such technical reserves in the past, and R\u0026D was very risky. It was Xiao Tang who stood out from the crowd at the group office meeting. The meeting requires us to conduct research and development according to high standards and a high starting point." Qin Zhongnian introduced the situation to Xiao Wenjun.

"So, you are planning to build a multi-station machine tool when the opportunity arises?" Xiao Wenjun asked.

The processing of a mechanical part rarely involves only one processing position. For example, the most common flange plate in the factory is to open a number of holes on a metal plate. Using traditional machine tools to process flanges can only process one hole at a time. After processing, the flange needs to be removed from the fixture, re-clamped in another position, and then the next hole can be processed.

The so-called multi-station machine tool is to design several cutter spindles on the same machine tool. During operation, the cutters on each cutter spindle work at the same time to complete the processing of multiple positions at one time. For the flange mentioned earlier, if a six-station milling machine is used, six holes can be machined at one time, which reduces the trouble of repeatedly disassembling and assembling the workpiece, and also avoids the inaccuracy of each workpiece due to repeated clamping positions. The holes are unevenly distributed.

There are many large parts in automobiles, including hundreds of processing surfaces. If each processing surface is processed separately and has to be re-clamped every time, it is not only time-consuming and labor-intensive, but also extremely prone to errors. In order to improve production efficiency and ensure product quality, various multi-station machine tools are widely used in the automotive industry. Once the workpiece is clamped in place, it no longer needs to be moved. The machine tool will automatically find each processing position and select the appropriate one. The tool completes the machining.

Everyone can see the benefits of multi-station machine tools, but designing multi-station machine tools is not a simple matter. It is not difficult to combine various functions such as turning, milling, boring, drilling, and grinding on the same machine tool, but it is a huge problem to make these tools perform their respective duties without interfering with each other.

For example, metal cutting is vibrating. If several tools are processed at the same time, will they resonate with each other? How to eliminate this resonance and how to compensate for the accuracy impact caused by the vibration of other tools are all enough. Top machine tool designers like Qin Zhongnian are also afraid of difficult things.

For another example, the processing time of each part of the part may be long or short. If the processing rhythm cannot be designed well, there will be a situation where other parts have been processed and only one part is left occupying the entire machine tool. If this is the case, then the multi-station design will not only fail to improve production efficiency, but will also reduce the utilization efficiency of machine tools.

Because of these many problems, many machine tool companies dare not rush into the research and development of multi-station machine tools. They can only make a lot of profits by developing some special machine tools suitable for automobile manufacturing based on their original technical reserves.

Tang Zifeng has the vision of a time traveler and knows that China's automobile industry is still in the early stages of development. The scale in the future will be seven or eight times larger than it is now, and the demand for special machine tools will also be astronomical. Such a large market is completely worth investing huge sums of money to seize when the opportunity arises. The current investment in developing multi-station automobile-specific machine tools seems large, but compared with the benefits that can be obtained in the future, it is not worth mentioning.

"Yes, the core work of our technical department in the future is to develop multi-station machine tools for automobiles. The goal Xiao Tang set for us is to occupy more than 30% of the domestic automobile equipment market within five years." Qin Zhongnian said with Said somewhat proudly.

"Suhua and others make UAVs, which is similar to building cars. They also need multi-station machine tools. However, the scale of their parts is several orders of magnitude smaller than that of car parts, but the processing principle is the same." Xiao Wenjun said somewhat. Come back to think about it.

If Linji Group is developing a multi-station machine tool for automobile manufacturing, then it would not be difficult to help Suhua develop a set of multi-station machine tools for drone manufacturing.

The materials used in drones are far lower in strength than automobile materials, and metal cutting is less difficult. There is no need to consider factors such as shock resistance and high temperature resistance when designing machine tools. The structural stiffness requirements of machine tools are also lower, so they are easier to design. of.

Calculated in this way, Dahe Company paid 20 million yuan in research and development funds, and Linji Group really did not suffer any loss.

"Wenjun, you don't know something." Qin Zhongnian continued enthusiastically, "We agreed to design a machine tool specifically for drones for Dahe Company, and not only did we not suffer a loss, but we actually took a huge advantage from them.

"This Xiao Su, although he doesn't understand mechanical processing, is very mathematically savvy. He carefully analyzed their current production model and proposed ideas for merging some processing links. These ideas are also of great help to us in designing automotive machine tools. Inspiration. If Xiao Tang hadn’t told us to say it, I would have almost wanted to express my gratitude to Xiao Su.”

"Is there such a thing?" Xiao Wenjun was also a little surprised. She thought for a while, then nodded and said, "I understand, Uncle Qin, we are all engaged in mechanical design, and our way of thinking has become somewhat solidified. Su Hua is a Those who engage in software should use a software engineering way of thinking to analyze the machining process. The angle of analysis must be different from ours, so maybe it can give us some inspiration."

"That's right, that's what I meant." Qin Zhongnian said, "The concepts of modularity, interface, and coupling he proposed sounded a bit confusing to us at first. But later we thought about it and found that they are all very good concepts and can be used. Solve many of the problems that plague us.

"In addition, we are now designing automobile machine tools. Although we have visited some automobile factories for inspection, they are not very cooperative and it is difficult for us to understand their real needs. Suhua and others have been producing drones for some time, and there are Many experiences and lessons are very instructive for our development of machine tools.

"When we take on this project, we can fully communicate with them and use their experience in producing drones to guide the design of automotive machine tools. In this way, we will take advantage of too much."

"So that's it." Xiao Wenjun looked like he suddenly realized it, and then said to Qin Zhongnian falsely: "Uncle Qin, this is your fault. Since you want to learn from Su Hua's experience, why can't you tell him directly? ? You also helped Tang Zifeng deceive, sold the family, and asked them to help count the money. I remember Uncle Qin, you are not such a person. "

"Isn't this all caused by your family Zifeng?" Qin Zhongnian looked a little confused and pointed at Tang Zifeng to divert the fire.

Tang Zifeng smiled and said: "Honey, don't blame Chief Engineer Qin. He has always been opposed to me hiding the truth from Su Hua and the others. But think about it, Su Hua is such a shrewd person. If he knows that we If we need their production data, do you believe that he will blackmail me in return?"

"Su Hua is not such a person!" Xiao Wenjun choked. She said this, and she knew in her heart that Tang Zifeng's approach was right. Isn't that what business cooperation is like? There is no reason to show all your cards to the other party.

"Another point is that we will definitely not lose money when developing special machine tools for drones. Sooner or later, the drone market will become prosperous. Even if Dahe Company's skills are inferior to others, it will not be able to capture enough market in the end. share, even if it goes bankrupt, other drone companies will develop.

"We develop special machine tools for drones, and we don't just sell them to Suhua. You didn't see that there is no exclusivity clause in the agreement initialed by Suhua and I. Suhua knows that the mere 20 million yuan in R\u0026D funds is not enough to buy us out. design, so I dare not make such a request.

"At that time, if Dahe Company takes off, we will simply make money from Dahe Company and will not help their competitors. But if Dahe Company does not take off and the market share is insufficient, we can sell the equipment to other companies and it will be the same. Being able to recoup our R\u0026D investment.”

Tang Zifeng then told Xiao Wenjun his considerations. As a time traveler, he knows the market prospects of drones very well. The sales of millions of drones a year worldwide are enough to support a special machine tool market.

"Is there anyone like you who is a friend?"

Understanding that Tang Zifeng did not harm the public and enrich his private life, Xiao Wenjun felt relieved, and changed his stance and began to blame Tang Zifeng:

"Thankfully Xiaohui treats you like a biological uncle. Fatty calls you buddy one by one, but you actually plot against them like this."

"There is nothing we can do. The landlord's family has no surplus food." Tang Zifeng cried bitterly, "Wenjun, you don't know that in order to develop special multi-station machine tools for automobiles, our Linji Group is selling iron and steel. Suhua and the others are selling iron and steel. Man-machine has made a fortune, shouldn’t we support our opportunity?”

"To put it another way, you are right!" Xiao Wenjun criticized in a hesitant manner, and then asked: "So, Mr. Tang, you tricked me into coming to Linhe from the capital, and specifically asked me to join you and Su Hua. What do you want me to do during the negotiation?"

"I want to hand over the design of the drone-specific machine tool to you, and you can get a team together to do it. You don't have to have much contact with Chief Engineer Qin and his team first. After you come up with your design ideas, you two will discuss it and see. Can there be some mutual inspiration between the two teams?" Tang Zifeng said.

"No problem." Xiao Wenjun agreed readily, "I'll bring a few students over to do this. This topic is very challenging, and I think the students should be able to learn a lot from it."
