At present, the manufacturing processes of excavator bucket teeth mainly include three categories: sand casting, forging and precision casting. Among them, precision casting has become the mainstream manufacturing process on the market because of its moderate price, good appearance and precise size. Under the premise of controlling the quality of raw materials, the wear resistance of precision cast bucket teeth can even exceed that of forging-made bucket teeth. When purchasing and maintaining excavator bucket tooth castings, factors such as their material, manufacturing process, and working environment should be fully considered to ensure the normal operation and efficient operation of the excavator. At present, people on the market often use deburring devices when deburring excavator bucket tooth castings.
