Chapter 7

According to Yun Fei's estimation of becoming a master, camart company is not clear. This list is just a foreigner asking for directions, and the subsequent processing quantity will be much higher than 100. If kamat earns all the money this time, it will really become kamat's money making tool in the future. You know, after several years and other state-owned enterprises have imported enough CNC machine tools from the outside, and China's domestic CNC industry has developed, there are more private CNC equipment, so there are no more opportunities to make money.

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

RB's equipment is well maintained. Although it has been used for many years, the roller screw has little wear. The only thing is that it may have been used too long before. The guide rail has some wear, and the accuracy has an error of 0.02mm. However, there is no problem making the stainless steel thin-walled parts of camart company.

Camart's stainless steel parts, if not with R120 large arc inside and outside, and many conical surfaces, can't use CNC lathe at all.

Yunfei has planned that the CNC lathe is only used for finishing. In that way, there will be no problem for the two CNC lathes to start in two shifts 24 hours a day. He is a great master. At that time, he only needs to make the tooling and fixtures needed for finishing machining and compile the NC program for finishing machining.

By this time, he had begun to look for talented lathe workers in the ordinary lathe over there.

Car counting operators do not need several years of professional training as ordinary car operators. If you are just a CNC operator, just let them know the three buttons of start, stop and emergency stop. There is a fixture for fixture positioning. As long as you are not a fool, you can teach it again.

However, Yunfei's purpose is not only to train operators. He must train a large number of NC lathe workers and NC milling workers who can program independently as soon as possible. If the conditions are appropriate, he must also train machining center technicians who use CAD three-dimensional modeling software for programming. Otherwise, in the future, the reserve of human resources will not keep up with the expansion of factory business.

That evening, Wang Qingfeng came back with excitement on his face. He brought back not only the intention contract of camart company, 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 Yunfei that Kmart company basically agreed to other requirements in principle except that it did not give a clear answer to the processing fee. This batch of work, 120000! The business volume of shangqingfeng machinery, which is almost at the top of the original month, and the most important thing is that the profit of the 120000 processing fee is equivalent to the original half a year!

Yunfei is not happy. After all, it is just an intention contract. If the samples can't meet the other party's requirements at that time, there will be no joy. Yunfei didn't pour cold water on Wang Qingfeng. After all, he came to Shunfeng machinery and needed to take care of the boss's mood.

In his previous life, he didn't pay much attention to the feelings of his boss. He graduated from a key university and worked as a technician in the workshop for seven or eight years. As a result, he came to Shenzhen in this era inexplicably because he was depressed and drunk. When he woke up, he found himself lying on the edge of a pond. His body was no longer the original body, but the body of a strange 16-year-old boy. Fortunately, there are more than 100 yuan in the pocket of his new body.

I found many factories and didn't want me because I didn't have an ID card. Those who want their own jobs are those whose wages are only 40 or 50 low enough to smoke.

After leaving Wang Qingfeng and Zhang Rui with the requirement to recruit workers with technical secondary school degree or above majoring in machinery as soon as possible, Yun Fei left the silly two to the ordinary machining workshop and stared at the workers to make tooling fixtures for stainless steel parts.

If he didn't, he didn't know that the things made by those workers could meet his requirements.

Yun Fei's request made them silly. These days, technical secondary schools and universities are allocated by the state. How many young people can go to Guangzhou to wander around with a good national iron rice bowl? Even if there are, they are colluded with by those powerful foreign companies.

Yun Fei didn't care so much. Finally, he was entangled by Zhang Rui, so he had to lower his requirements. It's OK to graduate from high school! This made Zhang Rui twist his waist and leave happily.

Although it's hard to find a technical secondary school degree, there are still many people who come to the Pearl River Delta after graduating from high school. Qingfeng machinery gives apprentices a salary of 100 yuan a month, which can fully attract high school students who have just arrived here and can only earn 70 or 80 yuan a month.

After the blank of the sample came back, Yun Fei worked out the process route that night. Considering that the ordinary lathe workers of Qingfeng machinery have no experience in processing stainless steel, Yunfei wrote every process of the processing process in great detail. The processing speed, cutting depth and cutting speed of each process are clearly visible.

After forcing the workers still working to stop and tidy up the surrounding environmental sanitation, he told the workers in the whole workshop about 6S management, and then asked Yang Dezhi to start rough turning samples with two better skilled lathe workers.

At the beginning of processing, Yunfei took Yang Dezhi, the most skilled lathe worker, 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 to the car. However, it took him six hours to meet the requirements. He knew that he should have the strength of a class 8 lathe worker. For Yun Fei, I admire him very much. Such a young child can have such a skill, so I don't care that he is only a child who instructs the level 8 lathe worker.

After installing the workpiece with the four jaw chuck and aligning it, Yunfei first watched Yang Dezhi go for two knives. Seeing that the YG8 blade provided by the other party was not bad when used in his own factory, he was relieved and told Yang Dezhi to be careful not to waste it, so he returned to the data control workshop.

The reason why Yang Dezhi, who has not processed stainless steel, and two other lathe workers are not worried about scrapping the workpiece is not only because Yun Fei enlarged the allowance of two millimeters to four millimeters when formulating the process, but also because Yang Dezhi is very cautious, otherwise he will not become the leader of 30 lathe workers.

Including overtime, the sample processing takes three days.

In these three days, two CNC lathes are used to do the work of lathes needed to make fixtures. In this way, we can not only test the performance of the two CNC lathes, but also let the four lathe workers get started faster.

As long as you have the foundation of ordinary lathe, remember the G code of preparation function and M code of auxiliary function commonly used in dozens of NC codes, then understand that f, s and t represent cutting speed, machine speed and tool number respectively, and master the programming format of these NC codes, these young ordinary lathe workers will soon become NC lathe workers.

Yun Fei explained the usage and format of each function code to several apprentices older than himself, while drawing some simple and typical part drawings to let these young apprentices contact programming. He didn't have much time for these young apprentices to start slowly from the most basic theory.

If you want to start from the most basic theory, it must involve a series of basic and professional theories, such as machining technology, NC machining technology, engineering materials, tolerance and fit, engineering mechanics, mechanical drawing, electrical theory, maintenance and repair of NC machine tools, ladder programming and so on. After all, engineering is not a professional school, as long as it can train workers who can work.

His requirement for these young apprentices is to be able to understand the drawings and complete the processing program according to the drawing requirements. Therefore, the main content of his training for these workers is programming and machine tool operation. The operation of NC machine tool is just a tool setting problem and tool compensation setting. People who have no foundation can also be proficient in a short week.
