As the saying goes: a good turner in three years.

In fact, according to the apprenticeship system of the Beverly Factory, generally speaking, half a year is almost able to top the post, and one year is enough to be proficient in operating the lathe. Of course, this is talking about CNC machines.

It takes three years to become a good lathe worker, and he is talking about a general car operator. It is a well-known fact that the simpler things are, the harder they are to practice.

Lin Fan took the drawings of this magnesium alloy workpiece and made a serious study.

In fact, Lin Fan knew this drawing at a glance, but seeing Tu Min leading his apprentice to pout and wave the broom vigorously, he had to do something.

"Hmph!" Tu Min walked up to Lin Fan and hummed unhappily.

It is said that people are old and refined, Tu Min has lived for more than 50 years, and he can see Lin Fan's coy attitude at a glance.

But there was no way, Wang Jiande was watching from the side. The official level crushed people to death, and no matter how much he had an opinion on Lin Fan, he couldn't go up and squash this kid.

There was so much dust on this digital display machine that Tu Min cleaned it all morning and used three vacuum cleaners to barely see the original appearance of the machine. After cleaning, Tu Min and his apprentice became a gray man, and they could take out half a catty of ash when they plucked out their ears.

"It's hard work. Lin Fan said with a smile.

"Paralysis!" Tu Min opened his mouth and spat out a mouthful full of soil.

Fire extinguishers, fire sand ...... A large pile of fire extinguishing equipment sits next to the machine. Wang Jiande was still not at ease, and finally invited his master Liu Jian over again, saying that he wanted him to help Lin Fan.

Well, Liu Jian has changed from a master to a master.

But Liu Jian didn't have any opinions. Two days ago, Lin Fan was in a hurry to take up the post for what, he was clear in his heart.

"Master Lin, if you have any odd jobs, you can tell them. Liu Jian said with a smile. In the past few days, the dispatch room has arranged more work for him, and his salary has gone up, and Liu Jian's mood has improved.

"Master, you say that, but it's my life. Lin Fan also said with a smile.

Although the machining industry does not pay much attention to the inheritance of master and apprentice, Liu Jian has been his master for several days after all, and this generation can not be chaotic.

"What is not a long life. Xiaolin, let me be honest with you, I really don't know how to operate the digital display machine tool, and I haven't touched this magnesium alloy material. I can't help you with a lot of help, but I can only do some odd jobs for you......"

Speaking of this, Lin Fan was no longer polite to him. The two of them were used to cooperating, and they quickly put this workpiece on and found it right.

Since it is a digital display machine tool, the CNC program originally written by the programmer is useless.

Liu Jian, who is usually used to CNC machine tools, was numb at this time, looked at Lin Fan, who was still debugging the machine tool, and asked in a low voice: "How can you go under the knife?"

Lin Fan pointed to a few numbers on the operation panel, smiled and said, "Now, just look at these numbers." The top one is the z-axis coordinates, and the bottom one is the x-axis coordinates. ”

big

Zhi introduced the usage to Liu Jian, and Lin Fan manually controlled the turning tool close to the workpiece.

In the morning, when Tu Min was cleaning, Lin Fan touched the machine parameters of this digital display vertical lathe.

It is no wonder that Wang Jiande, the team leader, said that this machine tool is ready to sell scrap iron. The flatness of the machine tool is 0.2 millimeters, not to mention, the verticality is nearly half a millimeter! Don't underestimate this half millimeter, compared to the tolerance of 0.05 required on the drawing, if you don't get it right, the whole workpiece will be scrapped.

Fortunately, now it's just rough processing, and it's almost done.

The difficulty of magnesium alloy processing is different from that of materials such as cast iron and carbon steel. The most difficult thing in the processing of cast iron and carbon steel is finishing, because the accuracy of the workpiece is relatively high. And the most difficult thing in magnesium alloy processing is rough machining. Because magnesium alloy is prone to oxidation, the outermost layer of "skin" is the hardest and the most prone to fire.

Lin Fan worked patiently little by little.

Two hours later, the roughing was finally done.

Liu Jian has worked for so many years, and he has never been so nervous as he is today. Watching Lin Fan complete the preliminary rough processing, the heart that had been hanging finally fell back into his stomach.

"Master, please help me measure the verticality of the workpiece. Lin Fan turned his head and said to Liu Jian, who was excited.

"Good. Liu Jian picked up the verticality measuring instrument and put it on the workpiece to measure it, and he was stunned at that time.

"Half a day off!" Liu Jian felt a dizziness in front of him, and almost sat down on the workbench. Liu Jian's "one" refers to millimeters, and the difference is half a millimeter, that is, a difference of 0.5 millimeters.

He also read the drawings of this workpiece, and the process requirements on it are 0.05 mm......

Of course, Lin Fan knew that the verticality of this broken machine tool was half a millimeter, and the reason why he asked Liu Jian to measure it was to call the equipment repairman in the workshop through him.

The verticality of the machine tool is poor, this is a hardware problem, even if Lin Fan's technology is smart, this problem cannot be solved and there is no way to finish.

The workpiece that Lin Fan is doing now is related to whether the workshop can add another production line, Liu Jian ran to find the equipment repairman in a panic, followed by the team leader Wang Jiande and Tu Min and other operators.

"Lin Fan, what's going on?!" Wang Jiande asked worriedly. Speaking of which, he is also responsible, at that time, patronizing the problem of magnesium alloy flammability, he didn't expect that there was nothing wrong with the workpiece, but there was a problem with the machine tool.

Tu Min's face was full of schadenfreude: "Hey, what's going on! If you want me to say Lin Fan, you kid is a tiger! What kind of work are you doing, you don't have a little bit of pressure in your heart, and you don't know how to hit the accuracy of the machine tool before you go under the knife!...... No experience is no experience......"

Lin Fan saw that Tu Min was chattering endlessly, and said with a smile: "Master Tu, I disappointed you again this time." The workpiece is not wasted, and I deliberately leave a little more margin when I work...... When Master Zhao adjusts the accuracy of the machine tool, I will unload the work for you before I get off work......"

"You ......" Tu Min

His face immediately turned from red to black.

When a few workers who couldn't see it heard Lin Fan's words, they immediately squeezed and said, "Haha, Master Tu, you are too anxious." Before you can do anything, you are looking forward to Xiaolin doing the work ......"

"That's right, Master Tu, Lin Fan can give you a few dollars if he scraps his work, you are so happy!"

Listening to these heart-wrenching arguments, Tu Min's face turned from black to white, and from green to green.

was arguing, Fang Yining and Xu Yuanhang trotted all the way over.

Before he could get to him, Xu Yuanhang began to shout: "The workpiece is wasted?!Lin Fan, what are you doing to eat?!Do you know how important this workpiece is to our workshop?!Hurry up and pack up your things and get out!"

Lin Fan had a headache, he just finished scolding the old man and came to be fat again, can he still play happily?!

Wonderful!
