"Dan machine, Changji, and Jing machine have been eyeing the market of special machine tools for automobiles, but according to the situation we have, their current research and development ideas are still focused on traditional boring and milling machines, machining centers, and have not considered the development of special multi-station machine tools.

"Initially, the same is true of the R&D ideas proposed by our technical department, because the development of multi-station machine tools is too difficult, and we lacked such technical reserves in the past, and there is a great risk in R&D. It was Xiao Tang who overcame public opinion at the group office meeting and asked us to carry out research and development according to high standards and a high starting point. Qin Zhongnian introduced the situation to Xiao Wenjun.

"So, is the machine planning to build a multi-station machine tool?" asked Xiao Wenjun.

The machining of a mechanical part rarely involves only one machining position. For example, the most common flange in the factory is to open several holes in a metal plate. The flange can only be processed with a traditional machine tool, and the flange needs to be removed from the fixture after processing, and the next hole can be re-clamped in a different position.

The so-called multi-station machine tool is to design a number of tool axes on the same machine tool, and the tools on each tool axis work at the same time during operation, and complete the processing of multiple positions at one time. As mentioned above, 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 can also avoid the uneven distribution of each eyelet due to the inaccurate position of repeated clamping.

There are many large parts in automobiles, including hundreds of machining faces, and if each machining surface is machined separately and has to be re-clamped each 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, a variety of multi-station machine tools are widely used in the automotive industry, and the workpiece does not need to be moved after being clamped in place at one time, and the machine tool will automatically find each processing position and select the appropriate tool to complete the machining.

The benefits of transfer machines can be seen by anyone, but designing a transfer machine is not a simple task. It is not difficult to combine various functions such as turning, milling, boring, drilling, grinding and so on on the same machine, but it is a great challenge to make these tools perform their own duties without interfering with each other.

For example, metal cutting is vibration, several tools are processed at the same time, whether there will be resonance between each other, how to eliminate this resonance, and how to compensate for the impact of accuracy caused by the vibration of other tools, are enough to make a top machine tool designer like Qin Zhongnian inevitably have a sense of fear.

For example, the processing time of each part of the part is long and short, if the processing cycle cannot be designed, there will be other parts have been processed, and only one part occupies the whole machine tool. If this is the case, the design of so many stations will not only not improve productivity, but will also reduce the efficiency of machine utilization.

Because there are so many problems, many machine tool companies do not dare to rashly carry out the research and development of multi-station machine tools, but on the basis of the original technical reserves to develop some special machine tools suitable for automobile manufacturing, but also can make a lot of profits.

Tang Zifeng has the vision of a traverser, knowing that China's automobile industry is still in the early stage of development, and the scale of the future will be seven or eight times larger than now, and the demand for special machine tools will also be astronomical. Such a large market is completely worth investing a huge amount of money to seize it. The investment in the development of multi-station automotive-specific machines today may seem significant, but they are nothing compared to the benefits that can be achieved in the future.

"That's right, the core work of our technical department in the future is to develop multi-station machine tools for automobiles, and Xiao Tang has set us the goal of occupying more than 30% of the domestic automotive equipment market within five years. Qin Zhongnian said with a bit of pride.

"Suhua and they build drones, the situation is similar to that of making cars, and they also need multi-station machine tools, but the scale of their parts is several orders of magnitude smaller than that of auto parts, but the principle of processing is the same. Xiao Wenjun has a little aftertaste.

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

The strength of the materials used in drones is much lower than that of automotive materials, the difficulty of metal cutting is less, and there is no need to consider factors such as shock resistance and high temperature resistance when designing machine tools, and the structural rigidity requirements of machine tools are also lower, so it is easier to design.

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

"Wen Jun, you don't know. Qin Zhongnian continued with great interest, "We promised to design a special machine tool for drones for Dahe Company, not only did we not suffer, but we also took advantage of them."

"This Xiao Su, although he doesn't understand machining, is very mathematically minded. He carefully analyzed their current production mode and put forward the idea of merging some processing links to deal with them, which also greatly inspired us to design automobile machine tools. If it weren't for Xiao Tang not letting us say it, I would almost like 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 been somewhat solidified." Su Hua is a software person, he should use the way of thinking of software engineering to analyze the machining process, and the angle of analysis must be different from ours, so maybe it can give us some inspiration. ”

"Yes, that's what I meant. Qin Zhongnian said, "The concepts of modularization, interface, and coupling he proposed sounded a bit complicated to us at first, but then we figured it out and found that they were all very good concepts that could solve many problems that plagued us."

"In addition, we are now designing car machine tools, although we have also visited some car factories, but they are not particularly cooperative, and it is difficult for us to understand their real needs. They have been producing drones for a while, and there are a lot of lessons learned in the middle, which are very instructive for us to develop machine tools.

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

"I see. Xiao Wenjun made a sudden realization, and then said to Qin Zhongnian pretendedly: "Uncle Qin, this is your mistake. Since you want to learn from the experience of the Soviet, why can't you just tell him? You also helped Tang Zifeng to deceive, sold the family, and asked the family to help count the money. I remember Uncle Qin, you weren't like that. ”

"Isn't this all broken by your family's wind!" Qin Zhongnian's old face was a little unbearable, and he pointed at Tang Zifeng to divert the firepower.

Tang Zifeng said with a smile: "Wife, don't blame Chief Engineer Qin, he has always opposed me for hiding the truth from Su Hua and them." However, if you think about it, Su Hua is such a shrewd person, if you let him know that we need their production data, do you believe that he will turn around and slander me?"

"Su Hua is not this kind of person!" Xiao Wenjun choked. She said this, and she also understood in her heart that Tang Zifeng's approach was right, isn't business cooperation like this, how can there be a reason to show the hole cards to the other party.

"Another point is that we are now developing special machine tools for drones, and we will definitely not lose money. Sooner or later, the UAV market will be booming, even if Dahe Company's technology is not as good as others, and in the end it fails to grab enough market share, or even goes bankrupt directly, there will be other UAV companies to 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 I initialed with Su Hua. Suhua knew that the R&D funds of 20 million yuan were not enough to buy out our design, so he did not dare to make such a request.

"When the time comes, if Dahe Company does it, we will simply make money from Dahe Company and not help their competitors. But if Dahe does not do it and its market share is insufficient, we can sell the equipment to other companies and still be able to recover our R&D investment. ”

Tang Zifeng then told Xiao Wenjun about his considerations. As a traverser, he knows too well the market prospects of drones, and the sales of millions of them a year around the world are enough to support a special machine tool market.

"Do you have such a friend?"

understood that Tang Zifeng did not harm the public and private interests, Xiao Wenjun was relieved, and changed his position and began to blame Tang Zifeng:

"Loss Xiaohui treats you like an uncle, the fat man calls you a buddy one by one, and you actually calculate them like this. ”

"There's no way, the landlord's family has no surplus food. Tang Zifeng cried bitterly, "Wen Jun, don't you know, in order to develop multi-station automotive special machine tools, our Linji Group is smashing the pot and selling iron." Suhua and they made a fortune selling drones, shouldn't they support us on the plane?"

"It's all your reasoning!" Xiao Wenjun criticized with disgust, and then asked: "So, Mr. Tang, you tricked me from the capital to Linhe, and specially asked me to participate in the negotiations between you and the Suhua them, what are you going to let me do?"

"I want to leave the design of the special machine tool for drones to you, and you pull a team to do it. Don't have more contact with Chief Engineer Qin and his team, and after coming up with your design ideas, you two will learn to see if there can be some mutual inspiration between the two teams. Tang Zifeng said.

"No problem. Xiao Wenjun agreed very happily, "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." ”
