Jiang Yan led everyone to the production workshop, where advanced machine tools have begun to be used to produce parts.

After entering the workshop, I saw several mechanics operating the silver-gray machine tool, watching them put the blank on it, press the start button, and then operate it on the side, the machine tool made a uniform sound when it was running, the spindle rotated at high speed, the iron filings on the blank were cut down, and the prototype of a part appeared in front of everyone's eyes, and after a while, a complete part appeared in front of everyone's eyes, and the part from the blank to the overall cutting time has only passed less than twenty minutes. The speed of production is undoubtedly shocking.

For this, Jiang Yan is no stranger, and after the machine tool completely stopped, Jiang Yan asked everyone to gather in front of this machine tool and began to introduce its performance parameters. "This is our self-developed horizontal machining center, which integrates milling, turning, drilling and other functions, and can complete multi-lane machining of parts."

Jiang Yan picked up the parts that had just been processed and were still a little hot to show everyone,

"You see, the surface roughness of this part has reached 0.01 mm, which is far more than the machining accuracy of ordinary machine tools."

"Oh!" Several experts stared at the part, touching the surface with their hands, and couldn't help but exclaim.

"I also borrowed some automated machinery, which can achieve precise control and greatly improve processing efficiency and quality." Jiang Yan continued to explain.

Several students also gathered around, their eyes lit up, and they took out their notebooks to record the parameters.

"It's also amazing, it's a complete change from the way machines are operated." An old expert pushed his glasses and said in surprise.

"Comrade Jiang Yan, these machine tools you have developed are even more sophisticated than what we have seen in the data, which is really beyond our imagination!" The other old man also nodded repeatedly.

"Comrade Jiang Yan, you are really amazing, you can develop such advanced equipment by one person. Amazing, amazing, I admire you quite a bit right now. “

Jiang Yan waved his hand modestly: "This is thanks to the valuable experience accumulated by the teachers and pointed out the direction for us." This is only a preliminary exploration, and there is still a big gap between it and the truly advanced level in the world. “

Jiang Yan said this is not suspected of being a sycophant at all, in his previous life, Jiang Yan studied many books on the theory of mechanical manufacturing in college, and these people were responsible for compiling them, in other words, these old people can also be regarded as Jiang Yan's teachers, after recognizing these people just now, Jiang Yan's heart was quite surprised! That's why Jiang Yan said such things, but these people are a little unclear.

After visiting this machine tool, Jiang Yan took everyone to watch several other different types of machine tools, and after seeing it, everyone was full of praise for its excellent structure and silent performance.

Next, Jiang Yan took everyone to another workshop, where several machine tools were still being debugged.

"These are new machines that we are working on that will be more efficient and accurate than existing machines." Jiang Yan introduced.

These new machines are particularly eye-catching, with a silver-white body with an icy metallic sheen and well-organized wiring and piping.

Everyone gathered excitedly in front of a large lathe.

"The spindle speed of this lathe can reach 8,000 revolutions per minute, which is much higher than the speed of ordinary machine tools." Jiang Yan patted the body of the lathe.

"8000 rpm a minute, this ...... That's too fast, isn't it?" A middle-aged male engineer exclaimed.

"Yes, the high-speed spindle can be used for high-efficiency grinding, and you all know that the higher the speed, the manufacturing efficiency is greatly improved. And I've also optimized the key parts of the machine. Jiang Yan explained.

"Mr. Jiang, can you explain to us the design principle of this machine tool and what is unique." A female engineer said.

"Alright! I'll give you a brief explanation. Jiang Yan nodded when he saw their eager eyes

Next, Jiang Yan began to explain the innovations of the new machine tools, such as these machine tools absorb the design concept of automatic machine tools, and then realize semi-automatic operation and precise control.

The crowd listened with relish, chanting from time to time.

After the explanation, Jiang Yan asked, "Do you have any questions, comrades?"

So the students raised their hands to ask questions, many of which were quite sharp.

Jiang Yan patiently answered every question, and he could answer some sharp questions appropriately, without panic, completely with the demeanor of a general, and several old experts who watched it were also amazed again and again, and kept saying that the future is terrifying, "There are successors and other words." ”

I thought that the young female engineer was listening to Jiang Yan's answer on the side, and couldn't help but sigh: "Mr. Jiang is really amazing, not a person who studied abroad, this theoretical knowledge is also quite solid, you see that no matter what problem he asks, he can answer it head-to-head, and his explanation is relatively easy to understand, no wonder he is the chief engineer at such a young age." I don't know if he's married. “

This last sentence is very low, perhaps a kind of mumbling. However, such words were heard by a person next to the female engineer.

After hearing this, this person couldn't help but joke with the female engineer: "Senior sister, or I'll help you ask." ”

The female engineer's face turned red when she heard this, she turned her head and didn't say anything, and she didn't dare to look at Jiang Yan again, but he still pricked up his ears to listen carefully to what Jiang Yan said, and recorded it from time to time.

This morning of learning has benefited everyone a lot.

After a sumptuous lunch, Jiang Yan took everyone to the dormitory area, pointed to a few old tube buildings and said, "Teachers, students, the conditions here are a bit simple, please take a moment."

"It's okay, we don't care about the conditions." An old engineer smiled and said, "As long as we can learn new technology, we are willing to live in a tower!"

Everyone else enthusiastically said that they didn't care about the accommodation and came here to study.

Professor Wang walked up to Jiang Yan's side and whispered, "Little Jiang, these young people are used to living in the dormitory, and the conditions here are already very good for them. You don't have to worry about them. “

The visit to the machine tool has ended, Jiang Yan led everyone to the conference room, ready to start explaining the relevant knowledge of CNC machine tools. Time waits for no one, and now the West has begun to popularize the numerical control system. If it's a little slower, then it's going to be slow, and you need to get it out as soon as possible.

Everyone took out their notebooks, and their eyes were full of excitement.

Jiang Yan stood in front of the blackboard, picked up the chalk and began to explain: "CNC machine tool is an automatic machine tool developed on the basis of ordinary machine tools. It controls the movement of the machine tool through the numerical control system. The numerical control system is mainly composed of a program setting device, a data processing device, a servo system and a driving device. “

At this point, Jiang Yan paused, waited for everyone to digest the record, and then said: "The user first needs to write the processing program, and then input the program into the CNC system, and the system will analyze the program to control the machine tool to complete the processing. The biggest advantage of CNC machine tools is the automation and precision of processing. For the same processing task, the efficiency of CNC machine tools can be increased by several times to more than ten times compared with manual operation. “

As a student of Harbin Institute of Technology, everyone also knows about CNC machine tools, but after Jiang Yan's explanation, everyone's understanding is more profound.

At this time, a student raised his hand and asked: "Mr. Jiang, how does the CNC system analyze and execute the processing program?"

"That's a very good question." Jiang Yan approved. He then explained in detail how the program is parsed and how it works.

The lecture lasted almost three hours, and everyone's notebooks were already full of content. Jiang Yan also said that his mouth was dry.

"We're going to talk about it for today, and you can digest the basics." Jiang Yan said.

"Thank you, Mr. Jiang!" The crowd stood up and bowed.

Hearing them call themselves teachers, Jiang Yan couldn't help but be stunned, but thinking about it, these are all students who are still studying, and they can be called teachers when they give lectures to them.
