Description

technical field [0001] The invention relates to a device for ultrasonically assisted abrasive jet finishing, which is used for removing burrs from machined parts. The processing device also has certain universality, especially for small parts. Background technique [0002] With the development of science and technology, the precision requirements of mechanical products are getting higher and higher, and the demand for finishing technology is increasing. In the field of mechanical processing, with the miniaturization of parts and higher requirements, burr removal, as a technical difficulty in finishing processing, has become an industry research hotspot. For example, in the high-tech field of medical equipment, the structure of its parts is relatively complex and requires high precision. Burrs usually exist in the edges of parts and small special-shaped holes, which are difficult to remove and greatly affect their processing efficiency and quality. [0003] When mechanicall...
