Chapter 121 Quality First
That ordinary horizontal lathe is processing the third-stage compressor wheel of the turboprop six engine. This is a die forging, which is forged by the forging workshop of Fenghuang Factory. processing.

Rough machining is mainly to process blanks into semi-finished products. The amount of turning of metal materials is relatively large, and the workers are all deep-cutting. The turning depth of the turning tool is basically more than 5 meters, and even reaches a depth of 8 meters.

Lin Feng knew the lathe worker, Su Wanping, who was in his forties, considered an old lathe worker, and was processing these batches of blanks.

The first rough machining has been done, and one of the end faces of the blank has been turned up, and it is already very smooth, basically without scale, and now the second rough machining process is in progress.

Lin Feng noticed something was wrong, so he took a few steps forward and watched from the side while keeping a distance of three to five meters.

Su Wanping apparently didn't realize that Lin Feng was already standing behind him, still processing parts. After driving around, he stopped and compared one of the processed parts with a rag. Then compared the half-processed parts on the lathe.

It seemed that there was still a machining allowance, so he turned on the lathe to process it again, and then compared the dimensions with a rag.

stop, stop, stop!
Lin Feng felt a little angry, and said loudly, "Su Wanping, what are you doing? Where's your caliper?"

Su Wanping was slightly taken aback. Seeing that it was Lin Feng, he immediately put on a flattering smile, "Director Lin, my caliper was borrowed by someone else. It's okay. Even if you use a rag instead of the caliper, there will be no problem. I've done several batches of this part."

Lin Feng directly interrupted his defense.

"It's like playing the piano randomly. You are still an old lathe worker. This is a military product. If something goes wrong, who can bear the responsibility!"

Very loud sound.

Some people around looked over, and some workers even stopped. Wang Yalong happened to be at the production site, and immediately trotted over.

"Boss, what happened?"

Lin Feng was very annoyed that someone used a rag instead of a caliper to measure the size, which subverted the three views.

"Ask Su Wanping and let him speak for himself."

So many people looked at him, even Wang Yalong came over, Su Wanping finally realized the seriousness of the problem, his face turned red, he felt a little embarrassed, and hesitantly explained the matter briefly.

what!
There is such a thing! ! !
The workers next to me opened their eyes wide, never expecting it!
Wang Yalong became even more serious, and yelled loudly, "Su Wanping, look at your good deeds. If there is any quality problem with the parts, I'll take you down."

Lin Feng also had a dark face, and took a caliper to measure it himself. A total of seven parts have been processed in this process. Good guy, five of them are out of tolerance, and two of them are out of tolerance. The difference is more serious, more than 3 meters.

"Su Wanping, measure yourself."

Su Wanping took the truck to measure it, then lowered his head.

Lin Feng said distressedly, "This is an aviation part, a military product, the value of each piece of the fourth-stage compressor wheel of the turboprop six engine is more than [-] yuan, there are five pieces in total, and two of them are out of tolerance. The worse ones are more serious."

One piece is one thousand and five!
Everyone's salary is only a little more than 100 yuan a month, and one part is almost worth their annual salary. Su Wanping finally realized that the matter was serious.

At this time, it is estimated that Cai Wenhao, the director of the technical department, also came to the production site and stood beside him.

Su Wanping lowered his head and said in a low voice, "Director Lin, what should we do with these parts? Can we save them?"

Lin Feng didn't have a good face, "Don't ask me this question, you can ask Director Cai."

Cai Wenhao understood what was going on, took a caliper to measure the dimensions of those parts and said slowly, "Fortunately, it can be saved, but it would be a pity if it was really scrapped."

Lin Feng said loudly, "This is a profound lesson. It can be seen from this incident that some of our workers have a weak sense of quality. If this continues, there will be big problems."

"This matter must be dealt with seriously. Su Wanping deducted 20 yuan and made a review in the whole factory. The technical room took the lead in carrying out a quality rectification. It is necessary to improve everyone's quality awareness."

Everyone was secretly shocked.

Especially some people thought in their hearts that Director Lin looks very young and usually has almost no airs, but when he is serious, it is really scary, as if he is a different person.

After this incident, the equipment branch factory carried out a quality rectification. Every day, technicians conducted quality inspections at the production site. Su Wanping also wrote a review and posted it on the bulletin board of the equipment branch factory.

in the office.

Lin Feng is neatly writing down the list of purchased parts. This CNC broaching machine needs to import a lot of spare parts, especially the grating system, servo motor, PLC control system, etc., which must be imported from abroad.

It was full of several pages, and after two or three days of busy work, Lin Feng finally wrote the complete list, not only including the name, model, basic technical requirements of each spare parts, but also suggested manufacturers, etc.

Originally, Lin Feng wanted to write down the contact numbers and faxes of each supplier, but on second thought, forget it.

If these things are really written, it is a little difficult to explain, and others will find it strange, why do you know the contact information of every supplier.

After finishing this list, Lin Feng thought in his heart that he still needs to take care of it. This CNC broaching machine can apply for a patent, and he should apply for a patent as soon as possible. It is best to apply for an international patent. Intellectual property rights are very important.

Lin Feng's plan is very big, not only to manufacture such a CNC broaching machine for Phoenix Factory, but the market demand for such an advanced CNC broaching machine with such a large broaching stroke will not be small, and it will become an item of the equipment branch factory. important product.

In the future, there will be a second, third, and even Nth CNC broaching machine to be manufactured.

Checked the list again and felt that there was nothing wrong. Lin Feng took it out and went to Wang Tianfang's office.

"Mr. Wang, we have already made up the list of spare parts that need to be purchased for this CNC broaching machine."

"Oh, so fast." Wang Tianfang was a little surprised.

As far as he knows, just a few days ago, the equipment branch factory started the design work of this CNC broaching machine in an all-round way. In just such a short time, the list of spare parts that need to be imported and purchased came out.

It's simply super fast.

Lin Feng smiled and did not explain, because the explanation is not clear, and it cannot be said that it is provided by the system. I just wrote the list in my mind.

If you really want to ask, it means that you have long considered designing and developing this CNC broaching machine, and this list has long been under consideration. Fortunately, Wang Tianfang just asked this casually.

He took Lin Feng's list and looked at it seriously. As he looked at it, his brows frowned slightly.
