Chapter 430: Processing barrel (bottom)

We have a kind of high-strength steel.
Lewis quickly replied:
The hardness is relatively high and the processing is very difficult.

understanding. Guo Tai came to see the processing requirements, nod. If you calculate the performance of the m200 sniper rifle in his mind, the barrel wall is thin, and it must be achieved with the performance and excellent steel.
Tailai guessed that this design and material selection is to reduce weight. After all, the m200 he knows has an empty gun weighing 14 kilograms, and Barrett m82a1 has a fight. The caliber is small, the power is small, but the same weight, obviously a defect. It should still be in the design process, and I want to achieve weight reduction through higher grade steel.
Obviously, this increases the cost of materials and greatly increases the difficulty of processing. That is to say, during the design period, they need to verify the feasibility, only to find Mr. t, otherwise normal production is also looking for Guo Tailai, it is estimated that the gun will become a sky-high price. This
It can be understood why some dimensions are slightly different. The difference in the angle of the twist line should be different because the size is different.
"If you want to lose weight." Guo Tai looked at a few eyes, looked up and pointed at Lewis: "In fact, simply consider high-strength titanium alloy directly! You know, the strength definitely meets the needs, minus The effect is even better."
"I also want to consider production." Lewis agrees with Guo Tailai's statement, but still explained with a bitter smile. Of course, titanium alloys can reduce weight, but if you want to mass-produce, I am afraid that the cost will go to sea.
In the dream of the future, in 2010, the US nemo arms company launched a full titanium ar rifle called [ti]one, as the company advertised, this. 308 Winchester caliber ar rifle, almost all of the body is made of titanium, only the gun, the needle and the barrel use the usual steel, including the upper and lower casing, buffer tube, gun frame, and even protect Many components, such as wood, are directly cut from titanium. Do
The unit price of tube metal titanium is not very expensive, but due to the limited level of industrial processing at that time, the direct cutting of titanium is very difficult, which makes this [ti]one titanium rifle a veritable "local tyrant." The gun, which is priced at US$95,904 in the US, will reach RMB 620,000 in RMB, which is more than tens of times more than the average ar rifle in the gun market. by
It is difficult to process titanium, and there are also a large number of defective products during the production of the gun. Perhaps considering the purchasing power of users and reducing the cost of the project, nemo arms has also pushed these defective guns to the market. It is sold for $49,789, which is nearly 50% off.
That is the price after ten years. It is conceivable that if Guo Tailai can process a titanium alloy barrel for them, the price of this gun will be high. Guo
When Tailai mentions the titanium alloy barrel, Lewis can only smile, how can it? Following
Continued to turn back, and sure enough, the latter drawing is another barrel of different thickness. These barrels are machined to verify the design. "
I can do it with higher precision than this. After reading the drawings, Guo Tailai said to Lewis: "Of course, only pay according to the accuracy requirements of the drawings, don't worry. But..."
Going to Guo Tai can achieve higher precision, Lewis almost said it is not necessary, finally heard the following sentence, this is assured. However, Guo Tailai's only two words made Lewis nervous.
"According to your drawings, I can probably guess that your sniper rifle should have an effective range of anti-personnel weapons in the range of about 2,000 meters." Guo Tailai ignored the mood of Lewis and directly said his thoughts. "The bullets I haven't seen, but I guess, it should be a high-precision bullet that is machined from a homogeneous metal strip using CNC. But let me bluntly, your twist line design may constrain your range and shooting accuracy."
What? Lewis almost cried out. Guo Tailai guessed that the effective range and bullet design are all good. It is the number and method of Guo Tai. It can be guessed by the drawings of the barrel. It is incredible.
What is even more surprising is that Guo Tailai actually said that the design of the twist line will affect the range and shooting accuracy? How is this calculated? how is this possible?
"Of course, I will process according to the drawings. I charge very expensive. I hope that you are mentally prepared." Guo Tailai said with a smile: "But I guarantee the time and quality. If the price is settled, you can get it at this time tomorrow. The finished product is in the barrel. In addition, I have some suggestions on the design of the twist line. If you need it, you can buy it at the right price. Believe me, this can save you a lot of time."
how much is it? "Dare to find Mr. T, Xia'an tactics must have been psychologically prepared for high prices, Lewis directly asked Guo Tailai about the price.
"Please bargain with my assistant for bargaining." Guo Tailai politely asked Lin Jiayi to replace her position and bargain with Lewis. After walking for a while, she went to Mr. Pagani. can
Can it be because Guo Tailai did not expect him to make suggestions for the revision of the squall line. For the trust of his idol, Lewis communicated with the company for more than an hour on the phone, and finally reached an agreement. Two
The root gun was originally Lin Jiayi's price of 1.5 million US dollars. This is the custom price of high-precision barrels that Guo Tailai and Zhao Xiangbei said at the beginning. However, after several years, the processing technology has also developed. The processing method inevitably brought about a price drop, so I finally talked about $750,000.
However, this price is a prerequisite. Guo Tailai will provide a twist line design for Xia'an tactics. If the Xinyi line design is better than their own design, Xia'an tactics will provide a design cost of two million dollars. Of course, Guo Tailai's squall line design must be detailed drawings and reflected in the contract. The detailed contract is not afraid of Xia’an company and they will pay the bill. base
Under the premise of this cooperation, the price of the two barrels will be passed at half price. The cooperation was negotiated, the two sides drafted the contract, signed, and Guo Tailai also successfully obtained the five round steel rods that Liu brought with him to process the barrel.
Xia’an’s contract is very strict. Except for the finished products, all the scraps, scraps and even defective products in the process must be taken away. It is said that this is a brand new steel that cannot be leaked.
Guo Tailai did not care about this. It took only one day for Lewis to get four barrels, two original designs, and two Guo Tailai's modified designs.
