Metallographic Grinding And Polishing Techniques Revealed
Metallographic manual polishers are widely used in the field of material science research. They are mainly used to grind and polish the surface of metals, non-metals and other materials to obtain a smooth and flat surface. When operating the single position grinding polishing machine, mastering some grinding and polishing skills can improve work efficiency and surface quality. In this article, we will introduce the grinding and polishing skills of the single position grinding polishing machine to help you better use and maintain the equipment.
1. Choose the right grinding disc:
The grinding disc is one of the important accessories of the single position grinding polishing machine. Choosing the right grinding disc can improve the efficiency and quality of grinding and polishing. Grinding discs can be divided into many types according to different materials. When choosing a grinding disc, the appropriate type and particle size should be selected according to the properties of the material to be polished and the grinding and polishing requirements. For example, for hard materials, a grinding disc with a coarser particle size can be selected; for soft materials, a grinding disc with a finer particle size can be selected.
2. Control the grinding and polishing time:
The grinding and polishing time refers to the length of time that metallographic manual polishers perform grinding and polishing under continuous working conditions. Too long grinding and polishing time will cause the sample to be over-polished and the surface quality to decrease; too short grinding and polishing time may not achieve the expected polishing effect. Therefore, when operating a metallographic manual polishing machine, the appropriate grinding and polishing time should be controlled according to the properties and grinding and polishing requirements of the material to be polished. Generally speaking, hard materials require longer grinding and polishing time, while soft materials can shorten the grinding and polishing time.
3. Keep the grinding disc clean:
During the grinding and polishing process, the grinding disc will gradually be covered with impurities and contaminants, which will affect the grinding effect of the grinding disc and the surface quality of the sample. Therefore, when operating metallographic manual polishers, the equipment should be stopped regularly to remove impurities and contaminants on the grinding disc. In addition, the wear of the grinding disc should be checked regularly. If it is found to be severely worn, it should be replaced in time.
4. Regular maintenance of equipment:
Grinding polishing machine is a precision equipment. Regular maintenance can extend its service life and improve work efficiency. It is recommended to perform routine maintenance once a month, including checking whether the cable is loose, whether the lubricating oil is sufficient, and whether the grinding polishing machine has abnormal sounds. In addition, a comprehensive maintenance should be performed once a year, including changing the lubricating oil, cleaning the inside of the equipment, etc.
Mastering the grinding and polishing skills of metallographic manual polishers can improve work efficiency and sample surface quality. When operating the equipment, you should choose a suitable grinding disc, control the appropriate grinding and polishing time, keep the grinding disc clean, adjust the appropriate pressure, choose a suitable coolant, and maintain the equipment regularly. Only in this way can we better play the advantages of grinding polishing machine and provide strong support for material science research. I hope the above content can be of some help to you!
