Chen Haisheng and Li Junchao were busy observing the effects of the air conditioner and the drill bit, but they didn't notice Wu Haixia suddenly appearing next to them, she shouted loudly, "Wow!", so frightened that the two of them took two steps back, and looked in the direction of the air conditioner, thinking that something had happened to the air conditioner! After looking at it for a while, she said, "No problem!"

Chen Haisheng looked at Wu Haixia and asked, "Aren't you leaving? Why did you come here again? Why did you shout and scare us, thinking that the air conditioner was out of order?"

Wu Haixia replied with a smile: "Brother Haisheng, what kind of thing are you doing? Use cold air to blow cold air on the drill bit, so that you can win me? Are you in the water in your skull, just thinking about some messy things, what can this prove?"

Li Junchao smiled and said: "People who prove that they can't drill can also play as handy as you!

Wu Haixia replied with a smile: "This person who can't beat the drill machine can play the drill machine, I see that you can fight, and you will play such a lot, I believe it, but if you want to beat me, I'm afraid you can't do it?"

Chen Haisheng said with a smile: " Haixia girl, you can hit a few and then talk to me, then lose, don't blame me for not reminding you, other people's brains are good, we have to admit that just by us to do, there are some difficult things to do, can only find people with high skills to do, so that the salary is high, but also delay production, after all, there are not many people who do this thing, everywhere is constrained, if you want a simple and easy way to operate, ordinary people can do it, then the company's efficiency has been improved, and the cost has been reduced a lot?

"Okay, Brother Haisheng, don't say it, your blowing air conditioning on a drill bit is not a great invention, don't say that he is superb, I can't believe it! Is this method come up with by this kid? Brother Haisheng, don't say it so levitatively, why don't let me make a few molecular instruments and see if you are bragging!" Wu Haixia was a little skeptical by Chen Haisheng's words, but felt that the principle of using air conditioning to cool down was feasible.

Li Junchao turned off the drilling machine, walked out, and gave up his position to Wu Haixia. Wu Haixia came to the side of the drilling machine, picked up the molecular device and did it, when the drill bit was punched in, she obviously felt that the drill bit was much easier, as if the copper chips were not so blocking the drill bit, and the speed was much faster than before, the hole that was punched out in six seconds before was now only three and a half seconds to punch out, and it was not as hard to fight as before, I was always worried that the drill bit would break, but now the time has been shortened by nearly half, but there is no worry like before! After hitting a few shots one after another, I felt much more comfortable than before, and I didn't need to breathe, so I held my breath and beat it in one go. I feel much more at ease, and I don't have the same high tension as before!

Turned off the drilling machine, walked out and looked at Li Junchao, Wu Haixia couldn't help asking: "Li Junchao, you came up with this thing, brother is good?

Li Junchao was embarrassed to be praised, touched the back of his head and replied: "Sister, this, this, this thing is not what I thought of, I put forward this point of view, Brother Haisheng implemented it, I am at most half a ghost idea, hehehehe······"

Chen Haisheng smiled and said, "Boy, you have learned to be modest! Is this the ghost idea you came up with? Say that you can use air conditioning to physically cool down the drill, this little girl is also here, she can tell you a fair word! Little girl, tell Sister Haixia, what did this dead electrician do?"

The girl who was doing the molecular device next to her, about twenty years old, had a good appearance, and she saw Director Chen asking her to prove that the electrician Li Junchao was the electrician, so she had to smile and say: "Yes, this electrician said that he used air conditioning to blow, and he was afraid that we would hold our breath and suffocate our lungs, so he walked out, and it didn't take long for Mr. Chen to bring a small air conditioner, and connected a small pipe to the pipe that blew cold air inside, and blew cold air on the drill bit." After doing it for a long time, I don't know what they are doing? The two of them are laughing and laughing, and they are very interested!"

"Look at how smart and wise this kid is, Wu Haixia, have you decided to compete with him?

"Brother Haisheng, how can you admit defeat so easily, this kid is just a little smart, this doesn't count, we are not better than the drilling machine, or better than the lathe, the lathe has not been compared, this is not counted!" Wu Haixia smiled and left.

When Li Junchao saw her leaving, he chased after her and sneered: "Wu Haixia, you have to lose more than anything, I am a person who thinks of a way, and I will not do it as rigidly as you!"

"Okay, brother, you have that ability, my sister is willing to follow you to eat and drink spicy food, and the key is not as good as you say!

Li Junchao also understood what Wu Haixia meant, so he said, "Okay, I'll go and see, think of a way, and then say!"

Wu Haixia came to her lathe, is making an external tooth product, and Li Junchao did before the tapping of the inner tooth is a little different, on the lathe there is an extra hook knife with an outer arc, the tap is replaced by a plate tooth, the plate tooth is set on the outside of the tool frame, there is a fixed stop block, when the outer tooth is set, the plate tooth is moved to the mountain to be fixed, and then the plate tooth is put into the outer circle to carry out the process of setting the external thread. The outer thread of the sleeve needs a little technology, the moment the plate teeth go in, the lathe should be relaxed, let it self-attack in place, instantly knock down the gear, let the plate teeth withdraw, at the moment of retreat, the plate braces are a little slightly shaky, and the teeth out of the set are normal, if the plate braces exit to die, motionless, the thread, must be bitten off, even there is no room for activity, this is the biggest taboo of the outer teeth!

Seeing Wu Haixia doing it handily, he also wanted to try it.

Wu Haixia didn't teach him by hand this time, but let him see it by himself and understand it, even if he really has talent!

Li Junchao carefully watched the process of her operation: the first step is to punch the inner hole car outer circle, one step to complete, the drill bit and the outer circle knife are installed on a pressure plate, the following drill bit goes first, the upper outer circle knife hits a certain position, and then follows the punching knife to go in, at this time, gently press the small push rod with your hand, do not let the outer circle knife go in, due to the excessive resistance, and the rebound phenomenon, so that the outer circle becomes larger, become rougher, when the outer circle turning tool enters, it is necessary to slow down appropriately, so that the turning tool and the spindle speed are consistent, too fast, the outer circle size of the car is too large, too rough, too slow, the outer circle size is relatively reduced, and the inner hole also becomes largerLi Junchao also knows that this speed is very important, he counted the time and the speed of movement, and looked very carefully, very in place!

The second way, the groove outside the hook, that is, the groove where the rubber ring is placed at the interface, he also pulled it at one time, which is no problem.

Wu Haixia and Chen Haisheng stood on the side, watching, Chen Haisheng saw that Li Junchao was going to put on his outer teeth next, and couldn't help but sweat for him!

Wu Haixia wanted Li Junchao to die on the outer teeth, with a little expectation on her face, watching him fall into the ground.

This Li Junchao stopped the lathe, took a breath, and said: "This guy is a little difficult, the first two passes have passed, and the back level is a bit difficult! Brother Haisheng, the teeth are swaying slightly when you go in, and you can only get out so that you don't break your teeth, what does this mean?"

Chen Haisheng smiled, smiled brightly, it turned out that this guy still knew the severity, so he explained: "Brother, you shake the plate teeth now, see if the plate braces are a little slightly shaking, if you shake, there will be no problems when the plate braces go in! When you exit, it will shake a little, so that there will be no resistance on the exit path, bite very tightly, you will lose the space for tooth withdrawal, the thread will be bitten off part of the plate teeth, there will be a spike, and the products with high requirements will be scrapped!"

Li Junchao understood what Chen Haisheng meant, shook the plate braces, it was indeed a little slight, he carefully observed, it turned out that the backer leaned against a small part of the plate braces, so that the activity of the plate teeth was larger, if the backing increased, the area of the plate teeth was too large, and the plate braces could not move, and the threads that came out of the sleeve became pointed mouth threads, which would not be full.

After figuring this out, he relieved himself to set his teeth, knocked down the gear, and a foreign tooth joint was made and placed in front of Wu Haixia.

Wu Haixia looked at it, this craft was no different from what she did, she smiled reluctantly, she didn't know what to say.
