On the second day after Yun Fei became a master, he did not appear in the machining workshop, but always stayed in the workshop with only three CNC machine tools that he named the precision machining workshop.

It took a week to compile the ladder diagram program of the PLC system of the control machine tool with another CNC lathe and milling machine, and carried out an inspection of the three CNC machine tools, and carried out the necessary repairs and maintenance of these machine tools, of course, debugging is a must. Since he works in Wang Qingfeng's factory, he has to be worthy of the salary he gave him.

After Wang Qingfeng got Yun Fei's reply, he began to go to the Cammat company in Shenzhen to negotiate the price. Camat is not a foreign-funded enterprise, it is a Chinese company engaged in import and export trade in Shenzhen, but it has taken a foreign name.

Wang Qingfeng went with Yunfei's three major requirements - asking Kamat to extend the delivery date by half a month, provide special machine clamping tools for processing stainless steel, and pay Qingfeng Machinery a processing fee of 1,200 yuan, three times the original.

This made Wang Qingfeng, who was full of banknotes flying in front of him, almost fall from his chair to the ground. However, after listening to Yun Fei's explanation later, he still didn't believe it and went to Shenzhen with his secretary.

For the processing difficulty of the workpiece, as well as the accuracy, Yun Fei has a good idea in his heart. The price of this order received by the Cammat company is at least more than 200 US dollars, and you must know that in foreign countries, the processing fee for parts of this difficulty is at least 400 US dollars. If it's just this list, there's nothing, the key is what this list means, maybe only Yun Fei, a person from the next generation, knows it. This list is definitely a test for foreign companies in China.

It is estimated that Cammat Company is not clear, this list is just a foreigner asking for directions, and the number of subsequent processing will be much higher than 100. If all the money is earned by Kamat this time, it can really only become Kamat's money-making tool in the future. It is important to know that after waiting for a few years for state-owned enterprises to import enough CNC machine tools from outside, after the development of China's domestic CNC industry, there are more CNC equipment in the private sector, and there will be no more opportunities to make money.

At that time, if there is no scale and no huge processing capacity, sooner or later it will be dragged down by the gradually rising prices and labor wages. Later, in Chinese mainland, the competition in the processing industry almost entered the white heat.

The Japanese equipment is still very well maintained, although it has been used for many years, but the wear and tear of the roller screw is very small, the only thing is that it may have been used for too long before, the guide rail has some wear, and the accuracy has an error of 0.02mm, but there is no problem with the stainless steel thin-walled parts of the Camart company.

Cammat's stainless steel parts, if it were not for the large arc of R120 inside and outside, as well as a lot of cones, would not have used CNC lathes at all.

Yun Fei has already planned and planned, CNC lathes are only used for fine turning, so that there will be no problem for two CNC lathes to work in two shifts 24 hours a day. He, a master master, only needs to make the tooling and fixtures needed for finishing turning and program the NC program for finishing turning.

At this time, he had already begun to look for talented lathes over there.

Operators of several vehicles do not require several years of professional training like ordinary vehicle operation mechanics. If it's just a CNC operator, you only need to let them know the three buttons of start, stop and emergency stop. There is a fixture tooling positioning for clamping, as long as you are not a fool, it will be clear if you teach it once.

However, Yunfei's purpose is not only to train operators, he must train a large number of CNC lathes and CNC millers who can be programmed independently as soon as possible, the conditions are suitable, and the machining center technicians who use CAD three-dimensional modeling software for programming must also be trained, otherwise, in the future, human resources reserves will not be able to keep up with the expansion of factory business.

In the evening of the same day, Wang Qingfeng came back with excitement on his face. What he brought back was not only a contract of intent from Camart, but also a stainless steel blank weighing more than 80 kilograms. The other party requires that the sample must be made within five days, and then the other party will sign a formal contract with Qingfeng Machinery.

He told Yun Fei that except for the processing fee, Camat basically agreed to other requirements in principle, except for the processing fee. This batch of work, 120,000! The original business volume of Shangqingfeng Machinery is almost at the top, and the most important thing is that the profit of the processing fee of 120,000 yuan is worth the original half a year!

Yun Fei was not happy, after all, it was just a contract of intent, and if the sample could not meet the other party's requirements, it would be just a joy. Yun Fei didn't pour cold water on Wang Qingfeng, after all, he had only arrived at Shunfeng Machinery and needed to take care of the boss's emotions.

In his previous life, because he didn't pay much attention to the feelings of the boss, he graduated from a key university, worked as a technician in the workshop for seven or eight years and was not promoted, and as a result, he came to Shenzhen in this era because of depression and drunkenness. When he awoke, he found himself lying on the edge of a pond, and his body was no longer the same body, but the body of a strange sixteen or seventeen-year-old boy. Fortunately, there are still more than 100 yuan in the pocket of his new body.

I found many factories, but I didn't want myself because I didn't have an ID card. Those who want their own are those jobs whose wages are so low that they are only forty or fifty not enough to smoke.

After leaving Wang Qingfeng and Zhang Rui with a request to recruit workers with technical secondary school or above in mechanical engineering as soon as possible, Yun Fei left the dumbfounded two people to the ordinary machining workshop to stare at the workers to make the tooling and fixtures of stainless steel parts.

If he didn't keep it, he didn't know that what those workers made would meet his requirements.

Yun Fei's request made the two dumbfounded. In these years, technical secondary schools and universities are all allocated by the state, how many young people can put a good national iron job bowl and run to this place in Guangzhou? Even if there were, they were hooked up by those powerful foreign companies.

Yun Fei doesn't care so much, he was so entangled by Zhang Rui that he had no choice but to lower his requirements, and he could graduate from high school! This made Zhang Rui happily twist his thin waist and leave.

Although it is not easy to find a secondary school degree, but there are still a lot of people who come to the Pearl River Delta after graduating from high school, and Qingfeng Machinery gives apprentices a salary of one hundred yuan a month, which can fully attract high school students who have just arrived here and can only earn seventy or eighty yuan a month.

After the blank of the sample came back, Yunfei worked out the process route that night. Considering that the general lathe workers of Qingfeng Machinery have no experience in processing stainless steel, Yunfei wrote every process of the processing technology in great detail. The processing speed of each process, the depth of the knife, and the cutting speed are all vividly visible.

After forcing the workers who were still working to stop and tidy up the surrounding environmental sanitation, and then telling the workers of the entire workshop about the knowledge of 6S management, Yang Dezhi was asked to take two lathes with good skills to start rough turning samples.

At the beginning of processing, Yun Fei took Yang Dezhi, who had the best skills in the lathe, to work together, basically he said that Yang Dezhi worked, but Yang Dezhi was not impatient at all.

In the competition two days ago, Yang Dezhi also gave the slender pole out of the car, but it took him a full six hours to meet the requirements, and he knew that he should have the strength of an eighth-level lathe. For Yun Fei, I admired it very much, such a young child could actually have such a skill, so he no longer cared that the person who instructed him, the eighth-level lathe, was just a child.

After using the four-jaw chuck to load the workpiece and align it, Yun Fei watched Yang Dezhi walk two knives at the beginning, and saw that the YG8 blade provided by the other party was not bad when used in his own factory in the future, so he put his mind at ease and told Yang Dezhi to be careful not to waste it and returned to the CNC workshop.

The reason why he is not worried about Yang Dezhi, who has not processed stainless steel, and the other two lathes will scrap the workpiece is not only because Yun Fei enlarged the margin of two millimeters to four millimeters when formulating the process, but also because Yang Dezhi himself is a very cautious person, otherwise he would not become the leader of the thirty lathes.

Including overtime, it takes three days to process the prototype.

In the past three days, the lathes needed to do the fixtures are all done by two CNC lathes. In this way, not only can the performance of the two CNC lathes be tested, but also the four lathe workers can get started faster.

As long as you have the foundation of the general car, memorize the G code of the preparation function and the M code of the auxiliary function commonly used in dozens of NC codes, and then understand that the three codes of F, S and T represent the cutting speed, machine speed and tool number respectively, and then master the programming format of these NC codes, these young general lathe workers will soon be able to become CNC lathes.

Yun Fei explained the usage and format of each function code to several apprentices who were older than himself, and at the same time drew some simple and typical part diagrams for these young apprentices to contact programming. He didn't have much time for the young apprentices to slowly learn from the most basic theories.

If you want to start from the most basic theory, this has to involve a series of basic and professional theories such as "Machining Technology", "CNC Machining Technology", "Engineering Materials Science", "Tolerance and Fit", "Engineering Mechanics", "Mechanical Drawing", "Electrical Theory", "Maintenance and Maintenance of CNC Machine Tools", "Ladder Diagram Programming" and so on. After all, engineering is not a professional school, as long as it can train workers who can do the work.

His requirements for these young apprentices are only to be able to understand the drawings and complete the preparation of processing procedures according to the requirements of the drawings. Therefore, the main content of his training for these workers is programming and machine tool operation. The operation of CNC machine tools is only a setting of tool problems and tool compensation, that is, people who have no foundation can be proficient in just one week.
