Inadvertently, in a blink of an eye, the shadow of an old metallographic cutting machine drifted past. This confuses me. First, let's reminisce: Where did I ever see such an old metallographic cutting machine? Is it in the metallographic laboratory of a certain university? Is it a research institute in another place? But none of them look like it. Later, I remembered the Volkswagen Metallographic Laboratory I had visited when I first arrived at Chain Energy, so I thought of this old metallographic cutting machine.

      I still vividly remember when I first arrived in Changchun, getting off the train. This northern city was like a world of ice and snow, without experiencing the allure of the silver wrap. I only felt the cold invade my bone marrow, which was called a "; Cold;! For me, a visitor from Jiangnan, there was no trace of pity at all. I shuddered and quickly got into a taxi and rushed to the public. Although the winter here is chilly, the enthusiasm of Northeasterners has melted away all the outdoor ice, and the warmth here is harmonious. When I first arrived at the laboratory, I was still confused and a bit nervous. The entire laboratory seemed to be shrouded in a layer of light smoke, and I couldn't see the miscellaneous equipment and bottles inside. I didn't even see the vertical metallographic cutting machine I was maintaining. It happened to be lunch time, so I followed the client to the cafeteria in a daze to solve my stomach problem.

    Due to psychological issues, I also ate something in a daze. I quickly told the user to go back to the laboratory to check the malfunction. I just went there myself and didn't need to be accompanied. In fact, I was mentally anxious, hoping that no one would disturb me and I would figure out a way to troubleshoot the problem myself.

      I returned to the laboratory alone, and my heart calmed down a bit. This is when I started to see clearly: Pushing open the door of the laboratory, the first thing that caught my eye was a pot of green and vibrant Hupi Lan on the windowsill. Although the cold outside was chilling, the laboratory was filled with spring with this pot of green plant Hupi Lan. On the entire experimental platform around the laboratory, there were metallographic sample making equipment, including a inlay machine, polishing machine, and a microscope, as well as many storage racks filled with sandpaper, polishing cloth, as well as bottles, jars, and jars of polishing fluid and inlay materials. I only had some impressions, but I couldn't recognize each one clearly. After inspecting for a week, I finally saw my old metallographic cutting machine, tall and heavy, standing quietly in the corner of the wall, The outer shell is gray and not bright, the glass cover is no longer very transparent, the buttons on the control board are a bit blurry, and the handle is polished to a shiny finish, When I arrived, the manager told me that the repair was an old metallographic cutting machine, but I didn't expect it to be as old as this. Since I am a mechanical worker, it is not difficult to troubleshoot the problem after starting. After more than an hour of troubleshooting and debugging, the damaged spare parts were replaced, and my old metallographic cutting machine can run as usual again.

      I asked the customer, how many years has this device been in use? He was also at a loss. When he first came to work here, the metallographic cutting machine had been here for over a decade without any changes. This surprised me even more, as I gazed in amazement at the old metallographic cutting machine in silence, and then at the pot of tiger orchids on the windowsill.

    In this way, every time I come to this laboratory, I stop by this old metallographic cutting machine and listen to its heavy gasping buzzing sound. It was the first machine I had repaired in the metallographic industry, so I also had a special liking for it. In addition, its spirit of working tirelessly like an old hero makes me sincerely respect it!

      I came here today not for maintenance, but specifically to bid farewell to the retirement of this old metallographic cutting machine. After searching for equipment records, it has been in service for the public for a full 20 years. In the past twenty years, it has witnessed the vigorous development of Volkswagen in China and the astonishing changes in China. It is time to bid farewell, new equipment is in place, and the laboratory needs to be replaced with a new look. No matter how things change, the contribution made by this old metallographic cutting machine will never be erased. My old metallographic cutting machine, although retired, I still love you!
