Jiang Ronghua didn't know about these situations, he was angry and funny in his heart: It seems that Fang Gong really regards me here as a training ground for cultivating apprentices, in case the construction period is delayed, what should I do!

Fang Dongping seemed to see Jiang Ronghua's thoughts, and he said with a smile: "Boss Jiang, you don't have to worry, since I have already come, your problem will definitely be solved, and your construction period will not be delayed." ”

Jiang Ronghua sneered: "That's good...... That's ......."

After the test machine, Niu Xiaoqiang turned off the power of the planer, turned his head and said to Fang Dongping: "Master, after my careful observation, the vise is still very strong, and no loosening has been found, I think the problem should be in the cutter head, as for what the problem is, then you need to take the machine apart to see." ”

Fang Dongping snorted: "You haven't seen a planer, this time the master will come to disassemble it, you can just watch from the sidelines." ”

Jiang Ronghua hurriedly stopped Fang Dongping: "It's better for me to come, you are old, just guide you on the side." ”

Fang Dongping did not shirk: "Well, it's up to Boss Jiang of hard work." ”

Jiang Ronghua took out a wrench from the toolbox, quickly removed the outer cover, revealing the internal structure of the planer, and gently put the cover on the ground, "I have checked it many times, but I can't find the crux of the problem." ”

Niu Xiaoqiang immediately came to the front to take a closer look, and after seeing that he didn't have much effort, he pointed to a transmission gear and said, "Uncle Jiang, the color of this gear is relatively new, and it is a little different from other gears, did you just replace it recently?"

Jiang Ronghua nodded: "The original gear is seriously worn, so I bought a new one to replace it, and it has been used for less than three months now, far from exceeding the service life, and the problem should not be in this gear." ”

When Niu Xiaoqiang heard this, he asked, "Uncle Jiang, before the gear was replaced, did this planer have any quality problems?"

Jiang Ronghua shook his head: "That's not true." ”

Niu Xiaoqiang turned his head to look at Fang Dongping: "My master once said that no matter what kind of machinery it is, as long as the parts are replaced, they need to go through a run-in period, not that the replaced parts will not have problems if they are new, why don't we remove this gear and check it?"

Jiang Ronghua certainly knew the concept of the run-in period, but there were no problems after replacing the gears, which made him convinced of the quality of this new gear. If it was really a problem with the run-in period, the problem should have been manifested a long time ago, where could it wait until three months later?

After listening to Niu Xiaoqiang's proposal at this moment, Jiang Ronghua didn't want to agree, because he felt that it was a pure waste of time. But because of Fang Dongping's presence, he had to give this face, so he had to nod at the moment: "It's okay, I'll tear it down." ”

In this era, dry fitters basically have to know some maintenance techniques. If a worker who drives a machine tool doesn't even know how to maintain it, he is embarrassed to say hello to his co-workers when he goes out.

Jiang Ronghua used to be a fitter for nearly 20 years, and his maintenance skills are still very good, he is very skilled in disassembling the gears, and the whole process only takes less than 30 seconds, which is quite amazing.

"Master Maverick, what tools do you need to use to check?" Jiang Ronghua asked, placing the gears on the workbench next to the planer.

Niu Xiaoqiang stretched out his hand and picked up the level: "This is enough." ”

As he spoke, he picked up a rag and wiped the oil on the gears clean, then placed the level on the workbench to make sure the reading was normal, and then laid the level flat on the gears.

After just one glance, Niu Xiaoqiang found the clue: "Uncle Jiang, I just put the ruler on the workbench, and the measurement results show that the table is absolutely horizontal, but when I put the ruler on the horizontal plane of the gear, the reading has a deviation of plus or minus two degrees, if nothing else, the gear should have been slightly deformed." ”

Jiang Ronghua has been watching from the side, and Niu Xiaoqiang has not yet said the result, he has already seen it clearly. Hearing Erlu's words, he was angry, gritted his teeth and said: "Gao Qiao, this bastard, actually sells fake and shoddy products to me!"

Fang Dongping was very satisfied with Niu Xiaoqiang's performance, he first cast an approving look at Niu Xiaoqiang, and then suggested to Jiang Ronghua: "Boss Jiang, if you have spare gears here, just take care of it first, and talk about other things later." ”

Jiang Ronghua nodded with a gloomy face: "I'm in a hurry to catch up with the goods, so I can only do this first, and then I'll go to Takahashi's dog day to settle the account!"

Fang Dongping snorted, and turned his head to look at the milling machine: "Boss Jiang, where are the defective products processed by that milling machine?"

"There is a pile at the door, Fang Gong, you go and help check it, I will replace this gear first. ”

Fang Dongping nodded and came to the door with Niu Xiaoqiang.

Niu Xiaoqiang stretched out his hand to pick up a bearing, and asked in a low voice while inspecting it: "Master, according to our current work efficiency, I'm afraid that the problem will be solved before lunch, but you asked me to bring a change of clothes, is this an extra move?"

Fang Dongping stared at Niu Xiaoqiang with a smile: "Are you kid worried about making less money?"

Niu Xiaoqiang did not deny it: "My fourth sister is about to take the university entrance examination, and the family is now anxious to use the money, of course, if she can earn a little more, she can earn a little more." ”

Fang Dongping laughed: "I guessed this a long time ago, the main reason why you bring a change of clothes is because the problem cannot be completely solved." ”

Niu Xiaoqiang looked at Fang Dongping with some astonishment: "Will there be any problems after replacing the gears?"

Fang Dongping nodded: "You have seen the design drawings of the bearings with me, the batch of bearings urgently needed by Jiangbei Machinery Factory has such high requirements for accuracy, with the two simple equipment here of Boss Jiang, it is not easy to meet the process requirements of others, his technical level is not enough, only I can help him complete the production task in person." ”

Fang Dongping is a big expert in mechanical manufacturing, not only the theoretical knowledge is extremely strong, but the practical ability is also super first-class. He can rely on the simplest grinding machine to polish a blank into a bearing with the specifications! This kind of processing technology that completely relies on experience and feel is enough to be comparable to those eighth-level fitters! You must know that the eighth-level fitter is the top existence among the fitters!

The reason why he was selected to study in the Soviet Union was because he had a very high talent in mechanical manufacturing, and his theoretical level and practical ability were very strong.

Niu Xiaoqiang looked at Fang Dongping with admiration: "Master, you are so amazing!"

Fang Dongping smiled and patted Niu Xiaoqiang's head: "As long as you follow Master and study hard, you will definitely be as powerful as me in the future." ”
