Manufacturing Empire in the Valley

Chapter 846 Accuracy of Twenty Microns

Niu Xiaoqiang quickly completed the inspection according to the standard procedure in the manual, then he turned his head and asked, "Mr. Sam, I wonder if you can specify the specifications? I can process according to the specifications specified by you."

Niu Xiaoqiang asked Sam to come up with a question, and Sam did not hesitate. After stating the specifications, he pointed to a wooden box next to the machine tool: "The original blank of the part is in the box, you can find it yourself."

This is also a kind of test. There are several different blanks in the box. If you are not a knowledgeable person, you may not even be able to find the correct blank, let alone process parts that meet the specifications.

This was naturally no difficulty for Niu Xiaoqiang. He bent down to watch for a while, then picked up a blank part from the box, and fixed the blank on the vise.

Sam nodded secretly, and Packard asked in a low voice, "Uncle Sam, did he take the original billet by mistake?"

Sam replied, "No."

Under the watchful eyes of the four, Niu Xiaoqiang quickly entered the processing parameters on the machine tool.He checked one side carefully, and started the machine tool after confirming that it was correct.Accompanied by the buzzing of the machine, the machine tool started to run automatically.

Sam went to the display screen to check it, and nodded with satisfaction: "There is no problem, you are indeed a knowledgeable person."

Niu Xiaoqiang not only wants Sam to be satisfied with him, but he wants to completely calm the old man and let him be completely convinced by himself, so as not to spend effort to surrender later.

He smiled and said, "Mr. Sam, CNC machine tools can only be regarded as pediatrics for me. What I am really good at is manual processing technology."

The processing work in the United States is basically done by machine tools, and workers only need to learn the technology of operating machine tools.There is no need to rely on manual techniques for processing like Chinese craftsmen.

The reason is that American companies can purchase the most advanced machine tools in the world. As for China, even if you have money, foreign companies will not sell them to you. In desperation, Chinese technicians can only use manual instead of machine tools.

Therefore, Americans are not so familiar with manual processing technology. After listening to Niu Xiaoqiang's words, Sam showed a puzzled look on his face: "I don't know what you mean by manual processing technology?"

Niu Xiaoqiang looked at the wooden box containing the original parts: "Let me tell you, it is the original parts just now. I can make it meet the specifications specified by you through pure manual operation."

Sam looked at Niu Xiaoqiang in shock: "You, you're not kidding me, are you? The specification I specified just now has reached the level of μ. Are you sure you can achieve such precision purely by manual technology?"

Niu Xiaoqiang chuckled: "Is that okay, let me try it and then I'll know?"

Sam froze for a while, and then said: "Okay, I'll let you have a try and see if you can really do what you say."

Sam is full of curiosity now, and he really wants to see how a person completes high-precision parts processing with manual skills.

There is neither a milling machine nor a planer here. Niu Xiaoqiang can only rely on this CNC machine tool if he wants to realize manual processing.

He took off the processed parts, picked up a blank and fixed it on the vise, turned his head and asked, "There is no suitable equipment here. In order to save time, can I only process one noodle?"

Sam nodded: "No problem, just process one noodle."

Niu Xiaoqiang looked at Packard: "Mr. Packard, please prepare me a grinder for grinding."

Although Packard doesn't know much about CNC machine tools, he is still very familiar with grinders. He usually uses this kind of equipment to polish the car body. Hearing this, he nodded immediately: "I'll get it right away."

Niu Xiaoqiang stopped talking and picked up a caliper to measure the cutter head and the blank.After completing the measurement, he directly turned off the automatic mode of the CNC machine tool, and manually controlled the machine tool for cutting.

In the eyes of Linda and Tracy, Niu Xiaoqiang's actions didn't seem to have any extraordinary features, but in the eyes of very knowledgeable Sam, Niu Xiaoqiang's actions at this moment were simply challenging his cognition.

With the operation of the machine tool, metal chips are cut off and fall into the chip flute in curls.Niu Xiaoqiang's expression was very focused. While paying attention to the trajectory of the knife head, he adjusted the angle.

In less than a quarter of an hour, Niu Xiaoqiang completed three cutting operations.He shut down the machine tool, opened the vise, and took out the blank of the part that had been machined on one side.

Packard had brought the grinder and plugged it in.Niu Xiaoqiang touched the curved surface to be processed with his hands, and after knowing it well, he put the original blank on the ground and used a grinder for final grinding.

The ear-piercing sound of metal friction sounded, and the sparks scattered in all directions, attracting the attention of the four researchers who were working.They didn't know what Niu Xiaoqiang was doing, and they all showed curiosity on their faces.

Niu Xiaoqiang's movements are very skillful and serious.After five passes, he turned off the grinder and ran his fingers back and forth across the arc.No matter how ignorant people can see that this is an inspection.

Niu Xiaoqiang repeated confirmation several times and confirmed that there was no problem, then he stood up and smiled at Sam who was already stunned: "Mr. Sam, I have finished processing, please check it to see if it has reached the precision you specified .”

Sam snorted, and placed the parts on a professional measuring instrument for inspection.

Packard and the others all surrounded him, wanting to know the result of the examination as soon as possible.

To everyone's surprise, Sam checked it out, took the parts down, and started examining the device.

Trish couldn't help asking: "Uncle Sam, what are you doing?"

Sam replied while he was busy: "I'm checking if this device is malfunctioning."

Trish glanced at Packard, and then asked, "Why do you think this device is malfunctioning?"

"Because it would be incredible if it didn't break down."

Linda seemed to understand something, she interjected, "Could it be that Niu Xiaoqiang's machining accuracy has met the requirements after measurement?"

Sam nodded with a strange expression: "It looks like this at the moment."

Linda asked: "You said just now that if the instrument didn't fail, the result would be incredible. Why did you say that?"

This question also puzzled Packard and Trish, and both of them agreed.

Sam simply stopped the work at hand, stood up and looked directly at the three of them: "The processing precision I specified just now reached the micron level, twenty microns to be precise, with such a high precision, do you think it can be done with pure manual technology?" Is it processed?"
