Thermal Deformation Analysis of Local Induction Brazed Grinding Wheel

For the problem of high temperature deformation of local induction brazing grinding wheel matrix, a simplified heat source model was used to simulate the stress distribution and thermal deformation of grinding wheel matrix. The results show that the residual stress of grinding wheel matrix is mainly distributed near the brazing working face, and the closer to the working face, the bigger the residual stress. When the scanning speed is 0.5 mm/s, the peak value of grinding wheel matrix deformation is the minimum under different brazing temperature. Too slow or too fast scanning speed will lead to bigger deformation of the grinding wheel matrix. The local induction brazing test shows that the error between the actual deformation values and the simulation results is less than 5%, which proves that the simulation model is accurate and the simulation results are valuable.
