Chapter 871 The Necessity of Advanced Tools For Difficult-to-machine Materials

(I'm really sorry, I went out to do errands today, and I came back too late. Today, I will try to make more gourds.)

"Slower speed, slower speed, don't worry!" In the 611 processing experimental workshop, a five-axis machining center from Japan is rapidly processing the welded impeller, especially the main shaft, constantly fluctuating and eating. The knife volume is small.

Seeing this, Liu Yijiu could not help but hurriedly ask the technician operating the machining center to reduce the cutting speed and the spindle speed.

Superalloys are inherently hard.

"Look, does the effect come out? The processed surface is much better than the previous one..." Seeing that after reducing the cutting speed, the processed surface is much smoother than before, Liu Yijiu proudly Said with a smile.

But the technician next to him frowned, "Leader, although the cutting speed and rotation speed will make the machined surface smoother, the wear on the tool is more than twice the speed before. This will be a lot. The time is spent on changing the tool. At the same time, it will cause inconsistent machining accuracy, prolong machining time and reduce machining efficiency..."

For this forty-year-old technician who dared to point out his problems directly, Liu Yijiu could do nothing but embarrassment.

The CNC machine tool was made under his guidance, but it does not mean that he understands the impact of various parameter changes in the processing engineering on the processing quality and processing efficiency better than the professional operator.

Especially people explain to themselves very seriously.

If you switch to another leader, you will probably directly ask the other party to act according to your own rules.

Liu Yijiu did not do this, and nodded very sincerely, "It's true, let's follow yours. In terms of processing, I contact these every day, and I am more professional than us." After finishing speaking, he faced those who followed. Huang Qiaosong and others said, “Professional things must be entrusted to professional people. Because they understand more deeply than we do! It’s not that they can know more than them if they are at a higher level. They have specializations in the field of surgery. Just for fun."

Huang Qiaosong and others nodded sincerely in their faces, but they didn't agree with them in their hearts.

There is only a leader like Liu Yijiu, who is so idle, and has nothing to do with the production process all day long. These things are not things that the senior leaders should take care of. After the design is completed, there are specialized process engineers to take care of these, especially the production. The front-line skilled workers conduct experiments and discussions, and they will not be allowed to intervene at all.

Otherwise, any leader will have no time to do serious things all day long.

How did he know that Liu Yijiu was just testing their reaction?

However, Liu Yijiu previously required that the turbofan-8 engine must be produced according to his process, which made them somewhat preconceived.

In the past, Liu Yijiu didn’t know how to deal with the most basic things. Therefore, Huang Qiaosong and others felt that Liu Yijiu wanted to intervene. In the end, it was because of the opposition of the technicians that Liu Yijiu was persuaded with reasons. Will intervene.

The parameters of the machining center are adjusted. Even so, the production efficiency is not as high as expected.

Especially high-temperature alloys and titanium alloys are special metals that are difficult to process. Processing technology is a problem in the entire world.

And there is no more powerful special tool, which makes people a little embarrassed.

If a process cannot be completed, the tool must be replaced and reprocessed. In order to ensure the accuracy of the machining, at the end, the machine tool will even be allowed to run the machined parts dry to ensure the consistency of the entire machining accuracy.

"Leader, if we can resolutely solve the problem of the tool, the processing efficiency can be at least doubled. There are basically no ordinary parts on the engine. The processing of these parts is difficult from the beginning. It is necessary to ensure that the machining accuracy is consistent. It is necessary to use more wear-resistant tools, cubic boron carbide, diamond, the hardest tools currently used, to process such difficult-to-machine materials, especially when the cutting thickness is less than 0.02 mm in the final finishing, which makes the tool wear Faster..." When Liu Yijiu felt that the processing time was too long, if mass production was carried out, it would have a greater impact on the overall output.

Especially in the future, we will have to use existing technology to develop gas turbines. Whether it is a thermal power plant or a high-powered engine of a warship, it needs more powerful combustion turbines, which will cause conflicts between production demand and production capacity. Become more prominent.

The front-line technicians put forward their needs.

"Isn't the tool always improving? You comrades, too, it is not so easy to develop a new tool material! Otherwise, these materials will not be so difficult to process." For such a request, Huang Qiaosong is very satisfied. dissatisfied.

The problem of knives was supplied by the material unit of the Second District of the Ninth Hospital.

"There should be a tooling workshop, right? The cutting tool workshop should also be equipped. Especially many times we need special tools. There are not enough manpower in this area in the second district, and everyone has undertaken too much work. ..." The engine factory manufactures almost the most precise parts in this country.

There are also many special shaped parts. Even in the experimental workshop, future engine production will be placed here.

The future power plant will expand with this workshop as the core.

Liu Yijiu directly suggested establishing a cutting tool workshop.

The several measuring and cutting tool factories around Chengdu that are specially used for supporting various state-owned processing units are not as good as the Ninth Institute's own material units.

In particular, some high-precision testing equipment, cutting tool materials that are more difficult to process materials, whether it is Rongcheng Tool and Cutting Tool Factory or Self-hardening Alloy Factory, there is no way to provide it.

If they can provide it, it will make Liu Yijiu's material unit much easier.

"Director Liu, we have already had this idea of ​​setting up a cutting tool research center, but we don't have very good technicians." Huang Qiaosong frowned and said.

Even Zhao Liangbi is very interested in setting up a cutting tool research center.

Factory 132 has a workshop dedicated to making molds.

Now this workshop does not have much business because of their own unit, and the Ninth Institute has its own unit for its business. Only some orders with low technical difficulty and low precision requirements are given to them.

Such an order does not require too much man-hours, and too high technical force is not a good thing for the mold shop.

"This can be communicated with Rongcheng Tool Factory, Self-hardening Alloy Factory and other units, and let them borrow people. After researching it out, mass production can be given to them. In addition, there are also special tool and mold workshops in the aerospace base. The institute will mobilize some capable forces to start this matter." Liu Yijiu is not trying to expand his business.

Moreover, they don't have much interest in production.

"Director Liu, should I just let the 754 factory do such research and production? The staff can figure out a way..." Huang Qiaosong suggested.

Dealing with other units is not as easy as the internal units of the Ninth Hospital.

Moreover, the systems are different, and the factory's emphasis on production tasks is not consistent.

If the internal units of the Ninth Court issue the requirements, they will not be given time at all. The units below will complete the tasks as quickly as possible. However, other units are different and require multiple approvals, and then have to go through a lot of approvals. The efficiency of human management is much lower.

"Factory 754 doesn't have much scientific research capabilities!" Liu Yijiu frowned and said.

All the time, due to lack of people, all the scientific research forces of the Ninth Academy are concentrated in the headquarters. For the civilian units under its banner, they have not given much technical research and development capabilities. It is not that they do not want to give it, but that the talents trained in the country are insufficient When they are used, they can only give priority to the military industry.

All civilian technologies are derived from the military industry, but the products are different.

Seven or eight years have passed since the resumption of the college entrance examination. The country has trained millions of college students. The Ninth Institutes often give priority to selection, so naturally there is no big problem.

Zheng Hao mentioned it many times and asked Liu Yijiu to return his scientific research ability to his civilian production units. The Management Committee of the Ninth Academy also studied this matter.

But because there are too few people who can lead the project, giving these units R&D capabilities will not only produce no results, but will cause a considerable consumption of their resources.

"The 754 factory does not have it, but the 754 factory can take the lead, and they will negotiate with the Rongcheng Tool Factory and the Self-hardened Alloy Factory..."

"Are you thinking about coordination?" Liu Yijiu asked a few people with a smile.Thinking about it, I feel that there is nothing wrong with this."Workers must first sharpen their tools if they want to do their jobs well. We have developed advanced materials and must have advanced processing methods, otherwise, it will be the same as the difficulties we encounter right now."

Advanced cutting tools are very necessary for the improvement of manufacturing capacity.

If you always expect to make a purchase after it appears on the market, you can only wait for everything.

Waiting is not the style of the Ninth Hospital.

Moreover, this also has an advantage, that is, high-temperature alloys, titanium alloys and other materials are all researched by the Ninth Institute. They have a lot of various parameters and have a better understanding of material characteristics. Naturally, researching tools is better than other materials. Plants with poor technical capabilities are better.

"Can't keep up with the development of the times, technology products cannot be updated quickly, and always eat their own money, there is no need to consider the benefits of their units..." Liu Yijiu sighed and said, and then let Huang Qiaosong and others go. Did it.

He is preparing to replicate plants like umpo, a subsidiary of Russia's United Engine Plant in China, specializing in the research and development, production, maintenance and repair of turbofan engines, production and repair of helicopter parts, and various power equipment...
