Chapter 64 Corn Milling Cutter
Wang Tianfang was probably a little worried, so he deliberately asked the school, "Xiao Lin, if you design a milling tool, what kind of material will you use for the tool, and how many types are there?"

Of course, Lin Feng understood what Mr. Wang meant, and immediately replied, "I'm going to use tungsten-titanium-cobalt cemented carbide, carbon-titanium coating, and I have an end mill and a ball end mill..."

Lin Feng gave an overview.

Tungsten-titanium-cobalt cemented carbide is the best choice for machining superalloys. If there is another layer of carbon-titanium alloy on the milling cutter, the service life of the cutter will be increased by two to three times.

Such an answer is obviously very satisfying.

Wang Tianfang nodded slightly, "Xiao Lin, the design of the knives is also entrusted to you."

Zeng Zhihong said, "Xiao Lin, after the design drawings of the knives come out, hand them over to me directly, and I will find channels for the manufacture of the knives."

Originally, Fenghuang Factory also had its own tool and mold branch company, which had the strength to produce cutting tools, but this set of carbide milling cutters had high quality requirements and carbon-titanium coating, so they were not competent.

No need to think about it, Zeng Zhihong will use his relationships and channels to hand it over to a more powerful knife company to manufacture the knife as soon as possible.

Lin Feng left and left Wang Tianfang's office.

Zeng Zhihong said, "A very nice young man!"

Wang Tianfang was deeply touched, "Yes, he is indeed a very good young man. Two months ago, no one was familiar with the operation of our imported CNC five-axis, so Xiao Lin stepped forward..."

He told Zeng Zhihong some of Lin Feng's deeds, such as the operation of the CNC five-axis machine and the processing of test pieces, such as the return of the turboprop six engine to the factory for troubleshooting, and so on.

After listening carefully, Zeng Zhihong said, "Young people like this need to focus on training."

"Yes, I have also considered this issue. When the time is right, we should add more burdens to young people."

406 Workshop.

Lin Feng came back and walked into the process technology room, preparing for the processing of Zeng Zhihong's overall turbine disk, especially the design of those alloy knives.

As soon as he sat down in his seat, Yang Wenjie, who was next to him, approached with envy, "Brother Lin, I heard that Mr. Wang told you to come over, is it true?"

He is a little bit untrustworthy.

Who is Mr. Wang, the first brother of the technical system of the entire Phoenix Factory, and Lin Feng, just a small craftsman.

The gap between the two is too great. If Director Yan told Lin Feng to go over, he would be convinced.

But he heard from his colleagues more than once that Mr. Wang had called Lin Feng to come over, and Yang Wenjie believed it again.

Lin Feng said, "Boss Wang just asked me to come over for something."

Really!

It turned out to be true!

After getting the confirmation, Yang Wenjie became even more envious, and said in admiration, "Brother Lin, you are really awesome!"

Lin Feng smiled happily, took out some pencils and a knife, and began to sharpen the pencils seriously.

Some people have said that the day's work of the technicians in the Phoenix Factory begins with sharpening pencils, and it is true.

The first thing everyone does when they go to work is to sharpen the pencil, and only after sharpening the pencil can they draw.

At this time, there is no computer graphics, let alone CAD, and it can only be drawn by hand one by one. Every drawing is purely handmade.

Lin Feng sharpened a few pencils and started drawing, which is a design drawing of a carbide end mill.

Spread out a piece of white paper on the drawing board, Lin Feng took a pencil and a ruler, and drew the design of the knife stroke by stroke.

If there are professionals in cutting tool design nearby, you will definitely be slightly surprised, because what Lin Feng designed is not an ordinary carbide milling cutter.

It is a "corn milling cutter". The so-called corn milling cutter means that the blade is like a corn kernel. It has many advantages over traditional milling cutters.

Such as long service life and good cutting performance, all the cuttings are "C-type" metal shavings.

"C-type" metal shavings are very important, especially when processing deep holes and deep grooves, this kind of metal shavings are easily discharged by the coolant, will not be blocked, and are less likely to cause "digging knives" and other situations.

As far as Lin Feng knew, the huge Phoenix Factory did not have a single corn milling cutter, and all the milling cutters designed by the tooling department were traditional milling cutters.

Why design "corn milling cutter"?

Very simple!
As a reborn person, Lin Feng knew that corn milling cutters were widely used in later generations. In addition, after reading several professional books on cutting tool design and manufacturing, which mentioned and introduced this kind of milling cutter, Lin Feng was sure to design it.

Lin Feng lay on the table and drew the design of the corn milling cutter stroke by stroke. Before he knew it, more than an hour passed.

The design drawing was finally basically completed, Lin Feng put down the pencil and ruler, and began to check carefully.

At this time, Yang Wenjie came back from the production site and just sat down to take a sip of water when his gaze accidentally fell on Lin Feng's blueprint.

"what!"

"It seems to be an end mill, but it's very strange. How does its blade look like this? I've never seen it before."

Yang Wenjie, who was curious in his heart, leaned over and looked at the design drawing. At first, he thought it was the drawing sent by the cutting tool designer of the tooling department.

Because after the tooling department designers design the knives, they will usually send the drawings to the corresponding craftsmen, who will countersign, mainly to check the size of the knives and so on.

But this drawing does not seem to be sent by the tooling department, because the drawings sent by the tooling department are all signed, usually with three levels of signatures, including design, proofreading, and review.

This drawing does not have any signature, even the signature in the design column is blank.

Yang Wenjie asked tentatively, "Brother Lin, did you design this?"

He was a little uncertain. Sometimes the craftsman also drew a sketch of the tool, which was indeed a sketch, and only marked a few main dimensions.

Such design sketches are mainly given to the tool designers of the tooling department, and they will carry out detailed design on the basis of this sketch. After all, they are professional in tool design.

Seeing Yang Wenjie's surprised face, Lin Feng smiled and said happily, "Yes, this is the milling cutter I designed, and it will be used on that imported CNC five-axis."

What, you really designed it!

Knife design is such a professional design, you can actually do it!

Surprised, Yang Wenjie said, "Brother Lin, what kind of milling cutter is this? It seems to be different from the milling cutters we have seen before."

Lin Feng said, "We often use traditional milling cutters, but this is called a corn milling cutter. Compared with traditional milling cutters, it has many advantages..."

Lin Feng simply did a simple science popularization.

There were other craftsmen in the crafts and technology room, and they quickly noticed the situation here. Two or three relatively young craftsmen surrounded them and stood by and listened.

After listening to Lin Feng's speech, and looking at this design drawing of Lin Feng, a craftsman asked, "Gong Lin, how do you know so much?"

Why do you know so much?
Read more books!

Just as Lin Feng was about to answer, out of the corner of his eye, he saw Jiang Haitao, the technical director of the workshop, walking in from the process room.
