Description

technical field [0001] The invention relates to the technical field of ultrasonic-assisted magnetic grinding, in particular to a magnetic grinding device and method for ultrasonically combining high-pressure airflow on the inner wall of a cylinder. Background technique [0002] The rapid development of modern manufacturing industry has put forward higher requirements for precision finishing technology, so magnetic grinding technology was born. The magnetic abrasive forms a magnetic brush under the action of a magnetic field, which is driven by an external force to generate vibration, reciprocating and rotating motions, so that the abrasive scratches and impacts on the surface of the workpiece, thereby realizing the flexible finishing of the workpiece. Currently, magnetic fields are mainly generated by electromagnets or permanent magnets. However, the electromagnetic coil has a complex structure and serious heat generation, and it is difficult for the permanent magnet to gen...
