In this article, the features of magnetic abrasive finishing of contacting conical surfaces are considered. The main problems arising in the processing of critical operational surfaces of a conical geometric shape are described. The main task is to ensure the quality of the contacting conical surfaces of the ring and the synchronizer cone. As a solution to the problem, the application of the method of magnetic abrasive finishing is proposed. The main parameters of magnetic abrasive finishing and their influence on the effectiveness of the method are described. A method of magnetic abrasive finishing of conical and cylindrical surfaces is proposed, which is based on step-by-step processing taking into account the combination of various working movements. The simulation of the distribution of magnetic induction in the working gap during the processing of the conical surfaces of the ring and cone is carried out. Graphs of the distribution of magnetic induction along the treated surfaces are obtained. The results of the conducted studies allow us to evaluate the distribution of magnetic induction during the processing of conical surfaces in order to further consider the influence of the distribution of magnetic induction on the quality of the processed conical surfaces of mating products.
