Lin Fan was very depressed in his heart.

For no reason, Fang Yining, the little girl, signed up for the competition.

It's better than it, but she actually reported three projects at once!

The three projects are nothing, anyway, one sheep is also rushed, and two sheep are also released, and they will be finished one after another.

But things didn't go down according to the script.

No, the lathe in the morning test went well, and Lin Fan happily chatted and farted with people after the test. Who knew that something would go wrong in the afternoon......

Today's competition schedule was sent out before the opening ceremony.

Lin Fan glanced at it casually at that time, well, three exams. In the morning, the vertical lathe, and in the afternoon, the two sessions were floor boring and milling and gantry boring and milling.

As for whether it is the gantry type or the landing type first, it doesn't matter, Lin Fan didn't look carefully.

But when it was really time for the competition, when Lin Fan planned to find out which machine tool he was taking the exam on this schedule, he was suddenly dumbfounded.

Because he found that the competition arrangement showed that his floor boring and milling and gantry boring and milling were tested at the same time!

That's it!

Although Lin Fan has a system, this system doesn't know how to doppelgänger......

It is estimated that the person who arranged the competition never thought that someone would sign up for two projects at the same time, and when he saw the two Lin Fan, he thought that they had the same name and surname, so he directly arranged the competition time together. Seeing that the game was about to be played, a person suddenly appeared and said that he had reported the two, and the game time was the same.

The staff in the association were also confused: Why did you say this kind of thing earlier, now that the competition has started, how can you change the time?!

Of course, for Lin Fan, this problem is not unsolvable after all, it is nothing more than a piece of dry.

The only drawback is that the two machine tools that Lin Fan used to compete are relatively far away......

In fact, this is not impossible to solve, Lin Fan took the drawings used in the game and took a look, and formed a complete set of processing methods in his mind. He can directly control the machining of the machine by hand without writing a program.

This saves the time of writing the program, and he can compare the floor boring and milling and then calmly compare the gantry.

But that's a bit of a scary operation.

There was no other way, Lin Fan had to honestly put the workpiece on the ground-mounted boring and milling machine, program it, and run the cutter......

Then use the time of running the knife to run to the gantry boring and milling machine, work, write the program, and run the tool......

Then use the time of running the tool on the gantry bed to return to the floor bed, watch the processing status of the tool, change the blade, and unload the tool......

So, when everyone in the workshop was in full swing, Lin Fan became a beautiful landscape...... Ya is like a rabbit, running back and forth at both ends of the workshop.

Although there is certainly no problem with Lin Fan's written program, machining is different from other industries, and there are always some unexpected situations. For example, the material of the workpiece is unstable, the hardness of a certain position

It is particularly high, and the blade crumbles when machining to this position, such as the machining allowance at the cutting blank is too large, resulting in a series of problems such as piercing.

Therefore, normally, when the machine is running, the operator cannot leave the site for too long.

When Lin Fan ran to the fourth round-trip, Liu Binglong, who was standing on the side, finally couldn't hold back and stopped Lin Fan, who was running on all fours.

"Master Lin, Master Lin...... You wait......"

Lin Fan froze and looked at the old man Liu who was invigilating him in the morning: "What's wrong?"

"What are you running all this time around?" asked Liu Binglong strangely. He didn't know that Lin Fan still had a machine tool running over there.

Lin Fan roughly told him about the situation.

"What?!" Liu Binglong's eyes immediately widened, with a look of disbelief, "Two exams at once?!"

Lin Fan spread his hands, and Baba was also very helpless.

"No......" Liu Binglong shook his head, and pressed his right thumb to his temple, "You mean, you can also gantry boring and milling machine?!"

"yes. Lin Fan nodded naturally, "If you can land on the boring machine, of course you will have a gantry boring machine - this makes no difference." ”

Liu Binglong disagreed with Lin Fan's theory, but he didn't refute it face-to-face, and said to Lin Fan: "Let's go, go and see the machine ......tool of your competition over there."

Lin Fan stretched out his hand to stop Liu Binglong, and pointed to the floor-mounted boring and milling machine that he was running to: "Wait a while, old man, I have two minutes to change the knife here, and we will go over when I change the knife." ”

Liu Binglong nodded.

Experienced masters can often see at a glance how long the processing time is required for a processing part. There's nothing surprising about that. Although this Lin Fan is too young, he can actually turn vertically, bore and mill...... If you don't have such a little processing experience, it's not normal.

After changing the knife and restarting the program, Lin Fan called Liu Binglong to come to the gantry boring and milling machine together.

The floor boring and milling machine is the same as the gantry boring and milling machine in terms of operating principle, and the cutter is the main movement and the workpiece (worktable) movement is the auxiliary movement. However, there are differences between the two, mainly because the overall structure is not the same.

The overall structure of the gantry boring and milling machine is composed of a gantry, the beam moves up and down along the column guide rail, the beam is equipped with a vertical high-power multi-functional ram type boring and milling head, the boring and milling head slide plate moves left and right along the beam guide rail and its up and down movements, and the gantry frame moves longitudinally along the bed.

The floor boring and milling machine does not have a movable workbench, and the workpiece is fixed on the floor platform, which is suitable for processing workpieces with large size and weight.

Liu Binglong picked up the processing drawings, compared the program written by Lin Fan in the controller, and then looked at the workpiece being processed, as well as Lin Fan who was busy cleaning up the iron filings of the workpiece......

What the hell is this kid......

Liu Binglong looked at Lin Fan, and his heart twitched. Lao Tzu has been playing with the bed for so many years

, not to mention yourself, even if you have seen people, there are not a few masters among them. Most of them are specialized in a certain type of machine tools, or turning, milling, grinding and boring can come a little, but they are not transparent.

Like Lin Fan, who is young, but is so proficient in CNC machinery...... This is the first time I've seen it.

Lin Fan had noticed from this morning that the old man surnamed Liu was not quite right when he looked at him. It's like looking at a bare little daughter-in-law. Lin Fan's heart was furious for a while.

This old man looks at five people and six people, is it possible that he also has that kind of hobby?

If he really spoke, would he refuse? or refuse?

Seeing that Old Man Liu's eyes turned red.

Lin Fan was really scared, and walked up to him with a weak and weak look: "President Liu, I see that you have been holding back for a long time, if you have anything to say, just say it......"

Wonderful!
