[0002] Scrapers are the main tools for scraping, and T12A high-carbon tool steel is generally used to make scrapers. According to the different scraping surfaces of the workpiece, scrapers can be divided into three categories: flat scrapers, triangular scrapers and crescent scrapers. Flat scrapers are mainly used to scrape flat surfaces, such as flat plates, flat rails, workbenches, etc., and can also be used to scrape external curved surfaces; triangular scrapers are one of the commonly used tools for scraping bearings; crescent scrapers are mainly used to scrape internal curved surfaces, such as the inner holes of movable bearings, etc. However, most existing devices use manual hand-held scrapers and grinding devices for grinding and polishing. Holding them for a long time is not only tiring but also has a certain risk of grinding errors, resulting in the product being unusable. At the same time, manual hand-holding is limited to a small number of scrapers. When encountering large quantities that need to be polished, it is not only inefficient but also time-consuming.
