After a few days of intense work, part of the preparation of the process specification has been completed, these process regulations, has been mapped, and has been issued to the production and processing site, the remaining part of the process specification, is still in the preparation of the tense preparation, may be after a period of time, will be completed all the preparation work.

The so-called photographic is also the blueprint. The process specification prepared by the process technician is not printed on ordinary white paper at the beginning, but printed on cellophane, which is generally A3 size cellophane.

Cellophane is a special translucent wax paper, and the process regulations are printed on the translucent wax paper page by page, which is convenient for the blueprint to be posted later.

There is a special photocopying machine, a bit like a large photocopier, the translucent wax paper is the template, and the photograph (that is, copying) is on the white paper of A3, and after the drawing, the white paper that was originally A3 becomes blue.

The white paper has become blue, the text on the white paper, and the process diagram are all blue, and the general machinery manufacturing enterprises are doing this, this method has been used since decades ago, and now, Tianfeng Technology Co., Ltd. is also doing this.

Straight to the point.

The second batch of machine tools and equipment purchased by Tianfeng Technology Co., Ltd., except for some imported equipment with a long procurement cycle, the rest are all in place, and have been installed and commissioned, and can be put into use, and the third batch of equipment has also been started.

After a few days of training and assessment, the group of skilled workers recruited by the Songzhou Winter Talent Recruitment Fair basically met the requirements for employment and can be employed for production.

Tianfeng Technology Co., Ltd. won the bid for more than 150 million processing business of E factory, and a large number of parts will be processed in Tianfeng Technology Co., Ltd. These days, there are a lot of blanks, and the incoming material area of the No. 1 plant has neatly placed a lot of blank parts waiting to be processed.

In addition to a large number of rough and semi-finished rough parts, there are also a lot of standard parts and fasteners for aero engines, which will be processed by Tianfeng Technology Company and provided to Factory E, and will eventually be assembled into one by one aero engines.

At the last bidding conference, Tianfeng Technology Co., Ltd. successfully won the aero engine standard parts and fasteners business package, which has the largest profit, because the standard parts and fasteners are directly processed from raw materials, directly processed into finished products in Tianfeng Technology Co., Ltd., and finally provided to factory E, and directly stored in the finished product warehouse of factory E.

Today, after the training, this group of skilled workers has taken up their posts, and many parts and blanks have begun to be processed on the machine tool, and the whole processing site is busy.

There are a lot more machine tools and equipment, there are a lot of workers, and there are so many parts, not busy, in addition, the processing site can see a few process technicians busy, now the No. 1 workshop, the technical force has been greatly enhanced, this time, Li Tianfeng one-time supplement to Zhang Can to supplement more than a dozen process technicians.

In addition, the leading organization of the No. 1 workshop has also been improved, with Tan Ke, the director of the workshop, Zhang Can, the deputy director of technology, and Zhao Shuqin, the deputy director of production.

Tan Ke was recruited by the human resources department, and Hu Xiao used to be the general manager of the Asia-Pacific region of Emerson Consulting, a world-class headhunting company, and he had a lot of resources in his hands.

Li Tianfeng personally read Tan Ke's resume, although he only has a bachelor's degree, but his work experience is very rich, what is valuable is that he has several years of work experience in aviation companies, Li Tianfeng personally interviewed Tan Ke, and finally made a decision, so Tan Ke, who was in his early forties, became the director of the No. 1 workshop, and his subordinates will be in charge of three or four hundred people.

Zhao Shuqin, deputy director of production, was quietly dug by Li Tianfeng from factory E, Zhao Shuqin, who was less than 30 years old, used to be the head of the production department of a workshop in factory E, Li Tianfeng knew Zhao Shuqin better, and in Li Tianfeng's eyes, Zhao Shuqin was good.

After a private contact, Li Tianfeng said what he meant, and Zhao Shuqin immediately resigned from Factory E and served as the deputy director of production in Workshop No. 1.

By the way, the people who came from Factory E during this period of time were not only Zhao Shuqin, but also several very good technicians, including a senior engineer, and more than a dozen skilled workers, including two technicians.

Workshop No. 1 was busy.

In addition to rough machining, semi-finishing of blank parts, the processing of aircraft engine fasteners, such as bolts and nuts, also began.

The processing of these bolts and nuts is also processing with supplied materials, factory E provides materials, Tianfeng Technology Company is responsible for processing, and finally processes them into qualified parts and sends them to factory E for acceptance and storage.

In the incoming area of the No. 1 workshop, in addition to the neatly placed blanks of various aviation parts, there are also bars of different sizes one by one.

The so-called bar stock is a round metal rod, the small one has a few millimeters in diameter, the large one has one or twenty millimeters, and even larger ones.

Aero engine bolts and nuts, even if they are standard parts, can never be purchased directly from the market, but must be processed by themselves, and the processing process is very strict, meticulous, and the technical content is relatively high, and the processing technology is different from ordinary bolts and nuts.

Of course, the materials are generally different, with titanium alloys, high-temperature alloys in the majority, in addition, there are some stainless steel materials, which are generally required according to aviation standards.

Zhao Shuqin, as the workshop director of the No. 1 workshop, has not been sitting in his office in the past few days, and has spent more time at the processing site, staring at it in person, not daring to relax in the slightest.

Zhang Can, the technical director, and Tan Ke, the production director, are basically the same, most of the time they stay at the production site, find problems, and correct them.

"Master Jin, you process the bolts of this drawing."

The production dispatcher of the No. 1 workshop distributed today's production task to Jin Youquan, a number of lathe workers, and when he got the task, Jin Youquan personally went to the on-site data room and lent out the processing drawings of the bolts.

First of all, digest the processing process drawings, which is when entering the factory for training, the trainer repeatedly emphasized, Jin Youquan remembers it firmly, and when he gets the drawings, he looks at it first.

The number of bolts is not much, but to the surprise of Master Jin, the process specification of this number of cars is very detailed, and half of the blueprint of A3 size is a process drawing, which is very formal.

The contour line of the part adopts 0.5 mm thick line, the processing line is 0.8 mm thick line, and the thin line is all 0.3 mm.

The other half of the length, basically all text, very detailed text description, just such a number of car process, detailed and detailed divided into more than a dozen steps, the so-called steps are the process steps, processing, according to the process step by step operation processing.

These process steps are very detailed, down to how to clamp the parts, how much tightening torque is used, how to process the first step when turning, what number of turning inserts to use, how much speed, how much depth, what matters need to be paid attention to, and so on.

So detailed, this is really our process processing process regulations. Jin Youquan couldn't believe his eyes, so detailed, these scientific process procedures, Jin Youquan was the first time he had seen them.

Jin Youquan used to be a worker in a large machinery processing company, and when he heard that Tianfeng Technology Company had a good environment, good treatment and large development space, he resigned from the original factory and applied for a job to join Tianfeng Technology Company.

In the previous enterprise, Jin Youquan has been working for more than ten years, and has never seen such a process specification, that a machining enterprise, the process specification is basically a page of blank paper, on which a simple drawing of a drawing, the processing size is marked, and the words "processing according to the drawing" are written next to it.

This comparison is simply a heaven and an earth. Jin Youquan was slightly surprised, carefully read the processing process card, and after basically digesting the content, he began to make preparations before processing in an orderly manner.

Before processing, a series of preparations should be made, and the process regulations were clearly written, and Jin Youquan began to prepare.

It took about half an hour, a qiē preparation is ready, before starting processing, Jin Youquan picked up a bar, according to the requirements of the process regulations, the standard furnace batch number, batch number on the bar one by one, and then, the bar according to the process requirements on his own CNC lathe.

"Superalloy, GH4133." Seeing such a material, Master Jin muttered in his heart, this is really the first time Master Jin has seen such a material, and he is not familiar with the performance. However, there are detailed process specifications, and it is good to operate according to the process specifications.

Jin Youquan processes M8 bolts, the length is relatively long, 65 mm in length, not standard bolts, belongs to non-standard bolts, such non-standard superalloy bolts are used in the turboprop B engine turbine part.

The turbine part of the aero engine is a hot part, the temperature is relatively high, the parts are generally made of high-temperature alloy materials, and the bolts used are also high-temperature alloy materials.

The turning of high-temperature alloy materials has poor performance and is easy to wear out tools, and the general turning speed is not very fast, but it does not mean that the slower the turning speed, the better.

The selection of the right number of turning tools, you can get a relatively high turning speed, a more suitable turning speed, Jin Youquan will process this superalloy bar, the turning speed is not low, the turning line speed is 65 meters.

Clamping bar material, knife alignment, alignment, inspection procedures, trial operation, process requirements, Jin Youquan a lot, are meticulously followed, after doing these, check again, Jin Youquan began the formal processing.

Pressing the start button of the machine tool, Jin Youquan found that his mood was slightly excited, this was the first part that Jin Youquan entered Tianfeng Technology Co., Ltd. to process.

The machine tool starts, the bar material clamped on the part begins to rotate, and the rotation is getting faster and faster, the machine tool turning tool begins to move, the turning tool is quickly positioned, and the "hiss" sound is soft, and the bar stock is gently cut into the fast rotating.
