Nowadays, although the price of ordinary carbon steel has fallen, the price of high-chromium alloy steel has fallen only slightly.A rough roll has a weight of more than ten tons and is worth more than 80,000 yuan.To scrap a blank, Yiming Company would lose more than 60,000 yuan.

No one wants to bear such unexpected losses!

Thinking of this, Xu Zhenming raised his eyes to Liu Yangde to see how he explained.

"The quality inspector of the No. 1 Machine Repair Factory of Nan'an Iron and Steel Group Company has been to the Jiangning Foundry and has performed non-destructive inspection on the forged blank workpiece, and found that there is an internal defect in the blank workpiece! This rough roll may be a rough part. It's scrapped! Hey..."

Liu Yangde sighed, his expression a little worried.

"It must be scrapped! The rough parts with internal cracks cannot be used!"

Upon hearing this, Xu Zhenming made a decisive decision.In terms of quality, he is unambiguous!Immediately, he asked Liu Yangde: "How is the purchase and sale contract between our company and Suning Foundry agreed? Are there any requirements regarding quality?"

"There are requirements! It has been agreed that non-destructive testing is required, and the rough parts that fail to pass will be returned!"

"That's good! At least we have not lost much financially! Are there any other difficulties?" Xu Zhenming secretly breathed a sigh of relief and asked why Liu Yangde was so troubled.

Liu Yangde smiled bitterly and said: "Boss Wang reported that they have scrapped a lot of blank parts, and the economic loss is huge. They don't want to cast a new blank again, and plan to re-forge this blank part for us to use!"

"No way!"

Xu Zhenming shook his head.

He picked up the phone on his desk and called Boss Wang of Suning Foundry.After a while, the call was connected.Xu Zhenming smiled and said, "Boss Wang, you want to settle the payment for these three rough rolls at a discounted price of 15%!"

"Boss Xu, why?" Boss Wang asked sadly on the other end of the phone.

"The fluidity of high-chromium cast steel is not good. I suggest you use lost foam casting. The temperature of the molten steel must be maintained. In this way, the cast slab should have fewer pores and the scrap rate of the workpiece will decrease!"

Xu Zhenming passed on the experience he had heard from his last life to Boss Wang, only to get the rough rolls quickly.

On the other end of the phone, Boss Wang was very happy, slapped his thigh violently, and shouted on the phone: "Yes, yes, yes! I have this idea, I have never tried it!"

The voice on the phone was so noisy that Liu Yangde, who was sitting not far away, could hear it.He looked at Xu Zhenming with surprise, and asked in surprise: "Mr. Xu! Do you know casting too?"

Casting is a profession and requires theoretical knowledge to support it.Xu Zhenming has dealt with many foundry engineers, and over time he also learned some experience and knowledge.

Seeing Liu Yangde's appearance, Xu Zhenming smiled and shook his head and said, "I don't learn casting, I just know a little about fur!"

Liu Yangde still didn't believe Xu Zhenming's humble words, and left with a relaxed expression.

After lunch, Xu Zhenming opened his posture in the office, ready to start designing mechanical drawings of the clothing computer cutting machine.During the day, the time was fragmented, and many people wanted to report to him. He couldn't write software code at ease, so he had to arrange to design mechanical drawings.

The principle of the clothing computer cutting machine is very similar to that of the CNC flame cutting machine, except that there is an additional cutter rotating servo motor on the cutter head, and the cutter can rotate at any angle at any time.

According to the classification of machine tools, this is a four-axis linkage machine tool: X axis is the length direction of the machine table; Y axis is the width direction.

The Z axis is responsible for the up and down movement of the cutter head.After the knife is dropped and the knife is raised, this direction no longer works in synchronization with the machine head.The servo motor responsible for the turning of the tool should be synchronized with the movement of the machine head to control the tool to adjust the angle in real time on the X-axis and Y-axis table.

Strictly speaking, this is a three-axis semi-linked CNC machine tool!

The motion theory is very simple, and the data model is readily available, but Xu Zhenming is a little worried about choosing accessories.

The precision requirements of the clothing computer model cutting machine are very high, which is an order of magnitude higher than that of the CNC flame cutting machine.The theoretical accuracy requirement is 0.025 mm, and the actual accuracy is about 0.05 mm.

There is a little trick to test the accuracy of this kind of machine tool: use the machine to cut a sample at the same time, with three rotation angles of zero, 120 and 240 degrees, plus a mirror sample.Finally, put these four models together for direct comparison, and the accuracy of the machine tool must be less than 0.05 mm to be qualified.

Don't look at the same kind of template, cut it into various angles to be exactly the same.Because of the accumulation of errors in the mechanical transmission system, these models are simply different!

Considering the mechanical transmission error, Xu Zhenming hesitated in choosing transmission: Should the servo motor timing belt be domestically produced or imported?Does the transmission of X-axis and Y-axis use ball screws and racks, or use aluminum alloy steel rails and ball screws?

The selection of these accessories must be determined at the early stage of the design of the clothing computer model cutting machine.Can customers accept the high precision and high cost?With low cost and low precision, Yiming’s products have no market!

Because of the backwardness of the domestic manufacturing industry, the quality of aluminum alloy steel guide rails can not be compared with foreign products at all, and there is curvature after cold drawing.Once the track has a curvature, the accuracy of the clothing computer model cutting machine is not guaranteed.

"Hey... I still envy Roland, Password, and the German manufacturers of computer model cutting machines for clothing. At least they don't have to worry about the performance of the accessory parts!"

Thinking of this, Xu Zhenming smiled bitterly and shook his head.

At the end, he decided to use a ball screw and a gear pinion drive.These accessories can be processed by Yiming's CNC machine tools.He would rather believe in the machining capabilities of his company than in the power of friendly forces!

As a result, the cost of the computer model cutting machine for clothing produced by Yiming Company is very high, and the price can only be about 30% lower than that of foreign brands, and product promotion is much more difficult.

"The timing belt can only be imported. Although it is more expensive, the irregular extension of the belt is small, and the error is much smaller! Hey...this can only be done!"

Xu Zhenming shook his head in frustration while drawing the drawings.

The domestic industry level is poor, and the processing accuracy of the accessory parts can't keep up, even if he has the best ideas!

While thinking about it, Liu Yangde knocked on the door with a smile.He came to Xu Zhenming's side and smiled and reported: "Mr. Xu, there are two groups of guests who must see you today. Do you have time to receive them?"

Liu Yangde is responsible for purchasing.He said that customers are usually suppliers, Xu Zhenming rarely takes time to receive suppliers, unless it is an important customer.

"Who are there?"

"One is Zhang Xiaonan from Wanwan Zhongyi Electric Machinery Factory, and the other is Wu Bin from Xiangnan Electric Machinery Factory!" Liu Yangde reported with a smile.

Wanwan Zhongyi Motor Factory used to be a foundry company under the Komatsu brand of a multinational company, capable of producing various types of servo motors.Yiming has ordered 10,000 servo motors from their factory.The sales director Zhang Xiaonan paid a return visit to major customers this time as usual. Xu Zhenming did not need to receive her.

The Shonan Electric Plant is a large state-owned enterprise, under the jurisdiction of the railway department.Their factory is launching a confidential project to tackle various high-precision and high-performance motors to support a key national project.Wu Bin, the section chief of the sales department, deserves Xu Zhenming's contact to discuss some confidential projects.

Considering this, Xu Zhenming raised his eyes to look at Liu Yangde, smiled and said, "First, please ask Section Chief Wu Bin to come to my office, and let Zhang Xiaonan come later!"

"Huh? Director Zhang's company is our key customer, how can we put it behind to receive it?"

After hearing the words, Liu Yangde's smile froze, unable to understand Xu Zhenming's meaning.

He is in charge of purchasing and knows the importance of Zhongyi Electric Factory.For the same model, the servo motor of Zhongyi Motor Factory is about 30% cheaper than the servo motor of Kudamatsu, Shiba Dong and other international brands.Such customers must maintain a good relationship, otherwise it will affect Yiming's procurement costs.

"It's okay! We are Zhongyi's customers, we are God, don't panic!"

Looking at Liu Yangde's appearance, Xu Zhenming smiled and comforted him.

Not long after, Liu Yangde led Wu Bin from the Xiangnan Electric Machinery Factory into Xu Zhenming's office.

Wu Bin is a middle-aged man, very thin, wears a pair of myopia glasses, and has a fair complexion. He is a middle-aged man.Speaking in Mandarin with an accent from Hunan Province, he said: "Mr. Xu! Thank you very much for your company's invitation, and hope to cooperate successfully with your company!"

He is gentle, speaks slowly, and is more sincere in attitude.

Xiangnan Motor Factory has set up a project to develop servo motors, which are mainly used in relevant confidential departments and do not sell products in the civilian market.However, the servo motors produced by their factory have a thick, large and stupid feeling, and the performance is really not flattering.

It was not until more than ten years later that the country launched the high-speed rail project, and the various high-performance motors of the Xiangnan Motor Factory barely caught up with the international level.Nowadays, Yiming's products are definitely not available!

Xu Zhenming asked Liu Yangde to invite Xiangnan Motor Factory to negotiate business in order to let them develop high-performance servo motors for civilian use and reduce Yiming's procurement costs.

Thinking of this, Xu Zhenming handed Wu Bin a cigarette and said with a smile: "Our company will purchase tens of thousands of servo motors a year, and I really want to give this order to a domestic enterprise!"

"what?"

Hearing this, Wu Bin was stunned on the spot.He has lit a lighter, but forgot to light himself a cigarette!

Seeing this situation, Xu Zhenming smiled and lit a cigarette for Wu Bin, with a cordial attitude.He smiled and said: "Chairman Wu, our company does not use the products of your factory at present. Your factory needs to develop new servo motors again!"

Of course, Wu Bin would not agree with Xu Zhenming's point of view, and shook his head with a smile: "Mr. Xu, you can't compare our factory's products with civilian products like this. In addition to being larger in size, our products have better efficacy!"

In front of outsiders, employees of any company will not admit that their products are of poor quality.Wu Bin is the same, with a strong sense of collective honor and pride.

Seeing this situation, Xu Zhenming pursed his lips and smiled.

He bent down and took out three servo motors of the same model from the cabinet of his desk. One was from Shimadzu, one was from German, and the other was from Wanwan Zhongyi.In terms of workmanship, Zhongyi's products are the worst; in terms of appearance and volume, Zhongyi's products are also the largest!

"Chairman Wu, if your factory can imitate Zhongyi's servo motors, our company will hand over 60% of the orders to you!"

Xu Zhenming pointed to the three motors on the desk with a smile and promised.

Wu Bin comes from a large state-owned unit and is used to being the boss.When he heard that he could only get 60% of the orders, he shook his head dissatisfied, and muttered, "Only 60% of the orders, this project is not worth setting up!"

In fact, he still doesn't know that foreign brands have been dominating the market in domestic high-precision servo motors.More than 20 years later, this is still the case.Companies engaged in motor production always complain: we have products but no market, where is the capital to continue to invest in research and development of new technologies and upgrade products.

It's better now, Xu Zhenming is ready to provide the market, but Wu Bin is unwilling to set up a project to develop a new servo motor.

Seeing this, Xu Zhenming couldn't help but shook his head.He intends to terminate the continued negotiations with the Xiangnan Electric Machinery Factory and seek a small private enterprise to cooperate in Wenrui City, Eastern Zhejiang Province.

There is a Yueqing second-hand motor trading market in Wenrui City, and there are many companies engaged in motor production.Although some people often pretend to be new ones with second-hand refurbished motors, there are still some companies that are good.

"Mr. Xu! To develop civil servo motors, it doesn't matter whether the project is approved or not. I have to take this question back to the factory leaders and let them make decisions!"

Wu Bin was embarrassed when he realized that he had made a mistake just now, and he quickly explained with a smile.

"Okay, Section Chief Wu! You can take these three prototypes back to make samples. In addition, if your factory really wants to set up a project, I can provide technical support for servo motor electronic control. Your factory only needs to be in electromagnetic conversion and motion structure. Just do in-depth research!"

Xu Zhenming smiled and stood up, preparing to see off the guests.

"Does your company still have technical reserves for servo motor control? If so, we will definitely be able to win this project!"

Hearing this amazing good news, Wu Bin was very excited, holding Xu Zhenming's hand unwilling to let go.

In his view: In terms of electromagnetic conversion technology and motion mechanism, Shonan Electric Factory is strong, and there should be no big problem.In fact, the Chinese people can't keep up with the technology in this area, there are reasons for materials and theories.

Xu Zhenming didn’t want to dispel his enthusiasm. He smiled and said, “As long as your factory can solve the hardware problem of the servo motor, we will be responsible for the electronic control software. In this way, your servo motor can be better matched with our products. use!"

"Mr. Xu! Do you have the technology in this area? If you can provide it to our factory, the relevant department will give you a medal!"

Wu Bin was very excited, speaking incoherently.

He had forgotten the identity of Xu Zhenming. He didn't know that Xu Zhenming didn't care about the pennants.

Xu Zhenming smiled and shook his arm. He released Wu Bin's hand and said, "Chairman Wu! Our company is willing to provide servo motor-related electronic control technology, not for other purposes. But to have a suitable one for our company. Domestic servo motor!"

The implication: He doesn't care about fame, but only the real benefits needed by Yiming's development.

In fact, Xu Zhenming has yet another meaning.He is for the safety of Yiming's supply chain, and does not want to be controlled by foreign or Taiwanese companies.Yiming Company will grow stronger in the future, and those who are interested will use the supply chain to suddenly attack Yiming Company.

This statement is extremely low-key, not like some people who sing high-key every day, and promote the pride of the country.Secretly, they are very extravagant, using all foreign goods.

Wu Bin misunderstood Xu Zhenming's words and thought Xu Zhenming was modest.He smiled and promised: "Mr. Xu! Once this kind of civilian servo motor overcomes the difficulties, our factory will definitely report your materials to the relevant departments, and the leaders will reward you!"

"Ha ha…"

Seeing Wu Bin's serious appearance, Xu Zhenming smiled but did not answer.He got up and sent Wu Bin out of the office door, and said some kind words of blessing.

Wu Bin didn't expect to get such a good opportunity on this trip to Southern Anhui Province, and he said goodbye to Xu Zhenming with a smile.

After leaving Wu Bin, Xu Zhenming welcomed a middle-aged beautiful woman with good temperament.This beautiful woman was called Zhang Xiaonan, and she actually took a man's name.

"Zhang, if you don't see you in person, I suspect you are a seven-foot man!" Looking at Zhang Xiaonan's business card, Xu Zhenming said half-jokingly.

Zhang Xiaonan is very tall, at over 1.7 meters, with fair skin and a faint fragrance of perfume.She whispered, "Mr. Xu, I belong to the Gaoshan ethnic group. I am the eldest at home. My parents hope that I can support my family's income like a man..."

She was good at talking and introduced her struggle experience to Xu Zhenming in a methodical manner, without saying anything about the business at all.
