Background

The scraper is the main tool for scraping, and is generally made of T12A high carbon tool steel. The scrapers can be divided into three categories, namely flat scrapers, triangular scrapers and crescent scrapers according to different scraping surfaces of the workpiece. The flat scraper is mainly used for scraping planes such as flat plates, flat rails, workbenches and the like, and can also be used for scraping outer curved surfaces; the triangular scraper is one of common tools for scraping a bearing bush; the crescent scraper is mainly used for scraping an inner curved surface such as an inner hole of a movable bearing. In some cases, due to material limitations, the secondary blade may be made by welding a waste saw blade on a sawing machine or a thin disc milling blade as a cutting head to a body. It is also possible to make the scraper with old files. The file is toothed, and cracks are easily generated in the forging process. Therefore, before forging, the teeth should be ground flat to prevent cracks from being forged. Or directly annealed by rasping and then planed or ground to the desired size.
