Abstract

The results of modeling of the topography of the magnetic field in the working gap are presented in the case
of magnetic-abrasive processing of the ball bearing treadmill. It is shown that the coverage of the treadmill with a pole
tip with a return radius ensures a uniform distribution of the magnetic induction in the working gap. Using the crescent
shape of the working gap increases the pressure of the ferro-abrasive powder on the treated surface. Calculation
of the magnitude of the pressure of the ferro-abrasive powder on the local parts of the treated surface is given. According
to the results of experimental studies, it has been shown that magnetic-abrasive processing of the ball bearing tread
path in comparison with superfinishing reduces the microroughness height up to 2 times and increases the residual
compressive stresses by an average of 20%.
