Chapter 34 Magee's Confusion and Showing Off
Then give it a try!
Select the turboprop six low-pressure turbine disk as the processing object, and verify this domestic CNC machine tool.

Lin Feng started a series of preparations, such as compiling the NC machining program, preparing the required tools and fixtures, and everything was in order.

The next day, in the morning.

Many people surrounded this machine tool, Lin Feng and his four apprentices, the leaders of the workshop included Yan Bing, Jiang Haitao, etc., as well as the after-sales and technical personnel of the machine tool factory.

"Director Yan, Director Jiang, everything is ready for processing." Lin Feng reported confidently.

Yan Bing waved his hand, "Start processing."

Lin Feng pressed the processing start button, and the machine started to work. Everyone watched the processing inside the machine through the glass safety door of the machine.

what!
As experts, the after-sales personnel and technicians of the machine tool manufacturing plant are very familiar with this machine tool. They only rough-machined one part originally, and they are gradually relieved.

Now, his complexion changed slightly!

There is something wrong with this!

This processing speed is too fast, no, to be precise, the spindle speed of the machine tool is very fast, it is estimated to reach about [-].

Dare to use the speed of [-] for rough machining, which is subversive and too bold!

They looked at each other in blank dismay, and their hearts gradually became tense, don't let anything go wrong!
Yan Bing was the first to notice the change in the expressions of these people from the machine tool manufacturing factory, and couldn't help asking, "What's the matter, is there a problem?"

"Director Yan, this speed is a bit high. This is rough machining, not finishing machining."

Rough machining generally has a characteristic. Although the machining accuracy is relatively low, the amount of material removal is large, the depth of cut and feed are relatively large, and the machining speed is not very high. For ordinary milling machines, it only takes dozens of revolutions, at most one, Two hundred revolutions.Even if it is a CNC milling machine, the milling speed is three to five hundred revolutions.

Now, there may be two thousand revolutions!
Jiang Haitao was engaged in technology, of course he also discovered this, his face gradually became serious, and he became a little worried.

"Xiao Lin, will there be any problems at such a high speed?"

Facing Director Jiang's question, Lin Feng said confidently, "Nothing will go wrong, don't worry, everyone."

Lin Feng dared to use such a high processing parameter, of course he was sure. He had carefully studied the cutting tools used in this processing. Several milling cutters were designed conservatively. Than, but also strong.

Seeing Lin Feng's confident appearance, Jiang Haitao gradually felt relieved, but the hearts of those people in the machine tool factory were still hanging.

After a while, that is three to five minutes, the machine tool started to vibrate slightly.

It is not normal for the machine tool to vibrate during the machining process. At this time, the technicians from the machine tool factory first understood Lin Feng's purpose for doing so.

Dare to adopt such a high processing parameter, originally to verify the performance of the machine tool. Obviously, when processing with high parameters, the machine tool did not stand the test and jittered.

Lin Feng said, "Did you see that the machine tool is vibrating, and the processing parameters used now have basically reached the limit of the machine tool."

Yan Bing, Jiang Haitao and the others nodded their heads in agreement, but the people in the machine tool factory felt more embarrassed and felt a little bit humiliated.

Lin Feng said, "There are still some defects in the design of your machine tool. I carefully read the technical manual that comes with the machine tool and think that the design can be improved from these aspects."

Lin Feng made several suggestions, all of which were on point, and were of great reference value.

This was where a dramatic scene occurred. At the beginning, the people in the machine tool factory didn't care, thinking that Lin Feng was playing tricks.

Gradually, their feelings changed.

The first was the technician from the machine tool factory. He looked shocked, and after recovering, he quickly took out his notebook and quickly recorded what Lin Feng said.

"Gong Lin, please repeat the first point. I didn't remember it just now." Comrade Technician looked modest.

Lin Feng smiled, and then talked about those suggestions one by one. The after-sales personnel and technicians of the machine tool factory all held notebooks in one hand and pens in the other, and took notes quickly, with extremely serious expressions on their faces.

Seeing this scene, Yan Bing and Jiang Haitao looked at each other quietly, and they nodded slightly, thinking almost at the same time, Xiao Lin is amazing, he knows more than the people in the machine tool factory.

After more than an hour, the processing is complete.

Lin Feng unloaded the part from the workbench of the machine tool and moved it to the workbench next to the machine tool.

"Everyone take a look, these are the five bosses that have been roughed."

The content of this process is the rough milling of these 5 bosses, and the processing efficiency has been roughly doubled. It used to take more than three hours, but now it only takes more than one hour.

Everyone's eyes are all on this part. Although it is only rough machining, the machining quality seems to be good, and the roughness of each machined surface is relatively good.

Then measure each processing size, without exception, all are qualified!
Although the machine tool shakes a little when processing with high parameters, it is generally acceptable.

Ma Ji probably felt a sense of loss when he heard about the machining results. He knew that if his hopes were lost, Lin Feng would probably be in charge of this domestic CNC machine tool.

However, Mr. Magee only lost two days and became active again. No, to be precise, he showed off a little.

There is a thick gold necklace around the neck, it is estimated that there are at least two taels.

"Little Ma, such a thick gold necklace is really enviable."

"Little Ma, how about lending me to wear it for two days?"

"Tsk tsk, I really didn't expect that Xiao Ma usually doesn't show his mountains and dews, and he didn't expect his family to be so rich."

This gold necklace is indeed related to his family. His mother has an ancestral gold bracelet, which was passed down from his grandmother, and Maggie secretly used it to make this gold necklace.

He is a man, so it is impossible to wear a gold bracelet, so he asked a master to process it and made the bracelet into a gold necklace.At that time, there was no 3D hard gold craft. The bracelet was not hollow, but a large solid bracelet, weighing more than 100 grams. Now it has become a large gold necklace around Maggie's neck.

As if he was afraid that others would not see him, Majid deliberately exposed the gold chain around his neck as much as possible. No, there were several people around him.

Lin Feng was seriously reading a professional book on knife design, and he read it very seriously, but such a big movement nearby made him read it.

Magee wore a gold chain, surrounded by young craftsmen.

Lin Feng thought in his heart, where did this guy get the gold chain, the kind of gold chain that looks relatively thick.

Just a little bit puzzled, Maggie actually came over and walked beside Lin Feng with a proud face.
