Unconsciously, most of 2018 has passed, and it is now the mid year equipment centralized maintenance season. According to the equipment usage plan, the metallographic cutting machine, polishing machine, inlaying machine, and microscope in our metallographic laboratory all need to be maintained. It's not mentioned, I have to find a professional engineer to do the maintenance of this year's instruments and equipment, especially for the maintenance of metallographic cutting machines, because I don't want tragedy to happen again.

    The process is as follows: New Year's Day in 2017 has just passed, and it is approaching the Spring Festival. We plan to conduct a system maintenance on the metallographic cutting machine and other equipment in the laboratory. As the equipment has already passed the warranty period, I also want to save some money, so I did not ask the factory to do the maintenance anymore. Instead, I directly contacted a service provider online. I have reviewed and verified the qualifications of this company online, and there are no problems, We had a good conversation with the young man they were selling, so without much thought, we signed a maintenance contract directly. According to the contract, we paid 80% of the contract amount and the remaining 20% as a deposit. After payment, contact the service provider to send engineers to come and maintain the equipment. Where did I know? The service provider changed their face, repeatedly pushing and resisting, and for various reasons, the engineer couldn't be in place. After nearly two months of struggle, it was already the end of the Chinese New Year, and finally we had a maintenance engineer. He was a young boy who wasn't familiar with the equipment yet. I was worried and always worried, especially when it came to maintaining the metallographic cutting machine. At that time, the cutting machine had some problems and the machine was unstable in operation, Often unable to get up or work properly after starting the machine, so he was specifically instructed to take good care of the metallographic cutting machine. I'm really afraid of everything. On the second day after maintenance, I happened to be using a metallographic cutting machine to take samples. As soon as I started the machine, it was accompanied by; Bang& Rdquo; With a loud bang and a burst of fireworks, I was stunned and quickly pulled down the power switch&hellip& Hellip;, Fortunately, I dodged in time and didn't get hurt. The final result is that the metallographic cutting machine was severely damaged, and the reason is simple: the electrical part is short circuited! My god, a metallographic cutting machine worth over 100000 yuan is almost scrapped in such an instant! Let's not talk about the next thing, it's all tears when we mention it.


This experience has made me swear that I have to find equipment suppliers for maintenance and upkeep of instruments and equipment. The price is more expensive and we can accept it, just to ensure safety. Suppliers all have professional after-sales engineers, and it is better to let professional people do professional things with greater reliability.

    No, our laboratory is equipped with ATM equipment from Germany, all purchased from Chain Metallurgy Company. It's not mentioned, and maintenance is also done by Chain Metallurgy! At the beginning of 2018, after signing the contract, Chain Energy's engineers came to inspect and maintain the vulnerable parts every quarter. In addition to regular maintenance, they also inspected and maintained the parts that needed to be replaced at any time. This week, they should come for mid year maintenance. The equipment has been running well for six months.


The metallographic cutting machines and other instruments and equipment in the laboratory require regular maintenance. Proper maintenance and proper operation of the equipment not only ensure work quality and efficiency, but also effectively extend the service life of the instruments and equipment. Therefore, regular maintenance and upkeep of laboratory instruments and equipment is essential, but it is important to find professional engineers from a professional company to do so. I hope my lesson can give you some inspiration, and it is my hope that it can help friends who read this article.
