God-level industrial master

Chapter 561 HD Satellite Map

Seeing that the boss personally gave the order, Zhu Yifeng quickly ordered the master worker who operated the precision five-axis machine. The master worker picked up a formal part and began to carefully clamp it on the workbench, ready to start processing.

This is a formal part. In the 336 factory, rough machining and semi-finishing are completed from the blank. Here, the precision machining of the blade profile will be carried out. Such a formal part has a longer processing cycle, as can be seen from the NC program. It takes more than an hour to machine such a single part.

The master worker took about ten minutes to install the blade, and then carefully checked the knife. After confirming that it was correct, he pressed the start button, and the processing started again.

The alloy milling cutter on the cutter head rotates rapidly, making a slight humming sound, the precision five-axis spindle moves rapidly, the alloy milling cutter touches the surface of the blade, and starts milling.

The milky white coolant is sprayed out to cool the blade surface, and everything can be seen clearly through the glass of the precision five-axis safety door.Yi Chunhua is the chief engineer of Factory 336. He is an expert in the field of processing technology. He knows that the current processing level has reached world-class.

A fan blade like this is more than 400 millimeters long, and the shape of the blade is so complicated. If it is processed by them, the precision milling of the blade alone will take several hours for each piece, and it will be processed according to the technical data. about an hour.

Jiuzhou Heavy Industry is processing in strict accordance with the requirements of process data.

Yi Chunhua and the others used to process in strict accordance with the parameters in the technical data, such as the rotation speed of the tool reached 6000 revolutions per minute, but he knew that their five-axis machining center could not stand it, so they adjusted the rotation speed of the tool down , set to 3000 rpm.

If the rotation speed of the tool is doubled, the processing efficiency will definitely be greatly reduced. It takes several hours for such a blade to be processed by the 336 factory, but it only takes more than one hour here.

The alloy milling cutter rapidly mills the blade profile, and a large number of fine metal chips are milled off, and the blade surface is very smooth and beautiful.Everyone watched it with gusto, and even reveled in it.

This kind of processing is really pleasing to the eye. More than an hour seems to have passed quickly. It was not until the machine tool stopped processing and started to retract that everyone came back to their senses.

Yi Chunhua said with emotion, the efficiency is too high, such a complex blade has already been processed.

Tang Fei was also very satisfied with the processing efficiency, and waved his hand: "Take off the blade, let's take a look first."

The master worker removed the blade from the workbench and handed it to Tang Fei. Tang Fei held the blade made of titanium alloy and looked at it with gusto, with a look of satisfaction on his face. Although the size had not yet been measured, But judging from its appearance, the processing quality of this blade is very good.

Only when the processing quality is very good, the surface of the parts will be so smooth, beautiful and delicate. If there are burrs on the processing surface, or the processing surface is rough, etc., it is often a processing problem.

At least the appearance of the blade is very good now. Tang Fei handed it to Yi Chunhua after reading it and said, "Boss Yi, take a look too, you are an expert in this field."

Yi Chunhua took the leaf, looked at it carefully, and looked excitedly on his face, "Mr. Tang, Mr. Zhu, although the size has not been measured, but experience tells me that this is an excellent Taste."

Tang Fei waved his hand and said, "Measure the size now, and let's all take a look at its processing quality."

Whether it is a good product, not only Tang Fei, everyone is looking forward to it.

Excellent products are products with a higher quality level than qualified products.Qualified products only meet the process and design requirements, and are only qualified, while high-quality products are on the premise of meeting the requirements, and many sizes reach the middle difference, which is better than the quality requirements.

First measure the main dimensions of the blades, and Zhu Yifeng specially arranged for an experienced quality inspector. After these dimensions were measured, the quality inspector reported: "Leaders, these dimensions are processed perfectly, basically They're all average."

The so-called medium difference means that it is in the middle range of the dimensional tolerance, without being biased, nor biased, and not exceeding the tolerance range.

Tang Fei said loudly: "Okay, okay, now arrange the scanning of the blade profile."

The profile of the fan blade is very complex, and the design needs to fully meet the requirements of aerodynamics. Such a complex blade profile cannot be measured by conventional methods, and must be precisely scanned by a three-dimensional measuring machine.

The blade was quickly sent to a three-coordinate measuring instrument not far away, and everyone followed. In everyone's eyes, the three-coordinate measuring instrument started to work, and began to intensively step on the surface of the blade. That is to scan the leaf shape.

About half an hour later, the scanning of the leaf shape was completed, and the printer printed out the scanning result. Tang Fei took the scanning result to look at it first, and then said with satisfaction: "Everyone, take a look, it completely meets the design requirements."

Yi Chunhua happily took the scan result from Tang Fei, and after looking at it carefully, he said with satisfaction, "The processing of the blade shape is perfect. This is a genuine and high-quality product."

When he was happy, he gave a thumbs up and praised: "Mr. Tang, Mr. Zhu, your processing ability is really strong. The fan blades that require such high precision and the blade shape are so complicated. You were an instant hit. The first one The leaves are the good stuff."

Tang Fei laughed.

The fan blades can be processed so perfectly, mainly due to three factors.The first is to have a high-precision, advanced CNC five-axis linkage machining center, and the second is to have reasonable processing steps and parameters including CNC programs.The third is that the quality +2 BUFF took effect.

For example, a complete set of process technology information is provided by the system. They are very detailed, and the parameters and steps are very clear. Even the CNC machining program is not programmed by the technicians of Jiuzhou Heavy Industries, but provided by the system.

Produced by the system, it must be a boutique!
It is not surprising that the tool selection is carried out in full accordance with the requirements of the system, the process parameters and steps specified by the system are used for processing, and the precision five-axis linkage CNC machining center exchanged from the system is used to process high-quality products.Tang Fei was completely relieved, knowing that after this batch of fan blades were processed, they were basically high-quality products.

CNC machining has a characteristic. If the first piece is unqualified, all the parts processed behind it will be unqualified. If the first piece is qualified, the parts behind it will basically be qualified, because the machining is controlled by the NC program and is affected by human factors. Small.

The first fan blade is a high-quality product, the second, the third...

The quality of the subsequent processed fan blades is good, at least half of them are high-quality products, and none of the substandard products have appeared.

For the next few days, this precision five-axis has been finishing the fan blades. Yi Chunhua and his technicians basically stayed in Jiuzhou Heavy Industry until all the blades were finished. .

After the finishing process of these blades is completed here, Yi Chunhua and the others can take the blades back and complete the follow-up finishing processes in the 336 factory, and then the formal fan blades will be formed and completely become finished products, which can be installed on fans in the future The disc becomes the fan rotor.

On the afternoon when the fan blades started to be finished, Tang Fei stayed at Jiuzhou Heavy Industry until the evening, and when he left, he told Zhu Yifeng to entertain Yi Chunhua and the others.

For a few days, the blades were all processed, and after packing, they were ready to be transported back to Factory 336 by air, and Yi Chunhua and others were also preparing to go back.

Before going back, in addition to thanking Zhu Yifeng and other senior executives of Jiuzhou Heavy Industry, he also went to Jiuzhou Industrial Group to express his gratitude to Tang Fei before boarding the plane.

It can be seen that Yi Chunhua is very happy. The fan blade finishing this time gave him a big surprise, completely exceeding his expectations.

He originally thought that there were dozens of fan blades.In Jiuzhou Heavy Industries, for finishing machining, it is enough if some of them can pass the processing. He is mentally prepared to scrap some of the fan blades.

As long as a part can be processed to pass, he will select these qualified fan blades and continue to carry out subsequent processing until the finished product. The fan blades of this level required by the first engine are enough.

These are the first-stage fan blades. Each engine needs a total of 23 pieces. Now all of them are qualified, and about half of them are high-quality products. Not only the first-stage blades required by the first engine are enough, but the second engine also needs There is surplus.

No wonder he was so happy. After thanking Tang Fei face to face, he happily returned to Factory 336 with his people and the box of fan blades.
