Description

technical field [0001] The invention belongs to the technical field of surface finishing of mechanical parts, in particular to a magnetic grinding tool finishing device and method with adjustable magnetic field and adaptive aperture. Background technique [0002] The surface quality of mechanical parts is an important indicator for evaluating the quality of mechanical parts, which directly affects the performance and life of the entire mechanical product. In the actual production process of mechanical parts, there are a series of problems such as difficult processing, poor processing quality and low processing efficiency in surface finishing of holes, especially for surface finishing of stepped holes, elongated holes, blind holes, curved surfaces, etc. . Therefore, it is particularly important to solve the problem of finishing the hole surface to improve the surface integrity of mechanical parts and the service performance and life of the whole machine. [0003] Magnetic a...
