Chapter 93 Roll up your sleeves and work hard

The sheet metal workshop first started the processing and manufacturing of the turbo shaft eight parts, and they all rushed ahead of the 406 workshop. There was no way, they had an advantage in the process flow.

Workshop 406 starts machining important and critical parts first, and these parts either require blanks, such as forging blanks, casting blanks, or bar stock.

Although these items are legal materials, they have to go through strict non-destructive inspection after arriving at the Phoenix factory, that is, ultrasonic inspection or fluorescent inspection, which takes time.

The sheet metal workshop is different. They can directly mark and cut the material after receiving the sheet, without so many cumbersome inspections.

Sheet metal workshop production and manufacturing site.

Several experienced workers were drawing lines, and it could be seen that their skills were very solid, especially that the leader, Master Wu, was an eighth-level fitter, and the lines drawn on the sheet were very standard.

Scribing, blanking, beveling, welding.
The site was very busy, Sun Jiangbo, Wang Tianfang, Meng Bowen and other factory leaders all came. Of course, they attached great importance to the production of the turboshaft [-].

The director of the sheet metal workshop said, "This is the compressor casing of the turboshaft eight. We have already started cutting the material. Over there is the combustion chamber casing of the turboshaft eighth. We have already reached the beveling process."

The leaders nodded in satisfaction, and Wang Tianfang once again emphasized the processing quality, which must be quality first.

The three major casings of turbo shaft eight, among which the compressor and combustion chamber casings are sheet metal parts, which are welded from pieces of sheet metal, and then go through a series of machining.

The turbine casing is not a sheet metal part, it is a forged blank, which can only be formed after machining one by one.

Within two days, the 406 workshop also started the processing and manufacturing of some turbo shaft eight parts, such as turbine discs, turbine casings, axial flow impellers and so on.

Without exception, these are all important and crucial parts.

The blade workshop has also started the processing of turbine blades, such as the first and second stage turbine blades, which are precision castings. After precision casting, the blade shape needs to be polished, and the tenons of the blades even need to be broached, etc.

The entire Phoenix Factory has entered the stage of manufacturing turboshaft eight engine parts, and all the employees in the factory rolled up their sleeves and worked hard.

Another month later.

Some parts began to enter the finishing process. For example, the axial flow impeller of the turboshaft eight entered the milling of the blade. After the blade milling, the axial flow impeller was basically completed, and there was only one fitter and final inspection after that, and then it could be put into storage.

Next to the imported CNC five-axis, a total of six axial flow impellers to be processed are neatly placed, and Hu Xiaoxiao and Ma Xiaoli are making preparations before processing.

Lin Feng was not around.

Because he was very relieved that the two apprentices had already graduated, and they could completely operate this machine tool alone and process various parts.

Clamp the parts, install each milling cutter, set the cutter, input the cutter compensation, determine the origin of the coordinates, etc.
Ma Xiaoli said, "Xiaoxiao, there should be no problem, it can be processed."

Hu Xiaoxiao also thought so, looked at the parts on the machine tool, and then pressed the start button, the machine tool started to work and started processing parts.

When the machine tool was started, the two of them relaxed. There was basically nothing to do. If there were no accidents, they could just wait for the machine tool to finish processing the parts.

In the afternoon, Lin Feng came over to have a look, and after a few glances, he left.

The next morning, Lin Feng appeared next to the machine tool again.

"Master, it's easy for you. I just came over halfway to take a look. Now the parts are almost finished."

Lin Feng smiled, "I guessed that the parts were almost finished, so I came here to have a look."

Don't worry about the two apprentices, it's because of the peace of mind that Lin Feng came here now, otherwise, he would have come here to teach hand in hand.

After a while, the parts were processed, and the CNC machine tool, which had been working continuously for more than [-] hours, finally stopped.

The first axial-flow impeller of the turboshaft eight engine was processed in Fenghuang Factory, which was also the first part of several key and important parts that Workshop 406 undertook to manufacture.

Seeing that the processing was completed, Hu Xiaoxiao was about to open the safety door of the machine tool to remove the part, but suddenly, she stopped.

Lin Feng also noticed that Yan Bing and Jiang Haitao walked over with Wang Tianfang and Meng Bowen.

The two deputy factory directors who were in charge of technology and in charge of production both came.

From a long distance away, Yan Bing asked loudly, "Xiao Lin, how is the processing of the parts?"

Lin Feng replied, "It's a coincidence that the leaders came here. The first piece has just been processed, and the parts are still on the machine tool before they can be removed."

Is it such a coincidence?

Several leaders laughed, and Wang Tianfang even waved, "Take off the parts, let's take a look first."

After Lin Feng signaled, Ma Xiaoli took the part off with a wrench, and used an air gun to blow off the coolant on the part, and finally wiped it with a clean rag.

This axial flow impeller was placed on the work table next to the machine tool and displayed in front of the leaders.

Wang Tianfang was the first to pick it up and have a look. The so-called expert looks at the doorway, and an expert watches the excitement. After looking at it, he nodded slightly.

Although I don't know the processing size, at least the appearance is very beautiful, like a handicraft, especially the milling lines on the blades are very delicate, without any rough feeling, and it feels very smooth.

The blades of the axial flow impeller not only have strict requirements on the blade shape, but also have requirements on the roughness of the blade surface. The smoother the blade surface, the better the aerodynamic performance. If it is too rough, the aerodynamic performance may be affected.

"You all have a look, the processing is very good."

Meng Bowen took a look at it, and praised, "It's so beautifully processed, it's really like a handicraft."

Yan Bing and Jiang Haitao glanced at each other quietly, and they both saw the joy in each other's eyes. They were praised by the two leaders. They both have radiance on their faces.

After looking at the axial-flow impeller, the two leaders walked to a vertical broaching machine not far away. Next to this broaching machine, several first-stage turbine discs of the turbo shaft eight were placed there. Ready to process.

Broaching processing is different from other processing. It needs to pull out the test material before processing the formal parts.

There are several knife boxes on the workbench next to the broaching bed, and the broaching knives have been packed in the knife boxes. It seems that the preparation work is almost done.

On the machine tool, the sample has also been installed, and two workers are preparing to install the knife box for the first stroke.

"Director Wang."

"Hello, Director Meng."

Seeing the two leaders coming, the two workers stopped and greeted the two leaders quickly.

Meng Bowen asked, "How is the preparation work? When will the official parts be broached?"

One of the workers replied, "Today, we will pull the test material, and if it goes well, we will start the broaching of the formal parts tomorrow."
