[0002] The sandblasting device in the production of fixed denture metal frameworks is a piece of equipment used for metal surface treatment. It is mainly used to clean, roughen or polish the surface of the metal framework to enhance the adhesion of subsequent ceramic or other coatings. Its core function is to remove oxide layers, impurities or adjust surface roughness by impacting the metal surface with high-speed jet abrasive particles (such as alumina, glass beads, etc.).

[0003] In the fabrication of fixed denture metal frameworks, sandblasting is a key process for improving surface cleanliness, roughness, and porcelain adhesion. Currently, sandblasting equipment is mostly operated manually or semi-automatically, which presents the following problems:
