Abstract

Different from the traditional macro structure block shape design of brazed grinding wheels and the micro structured grinding wheel surface design that is still difficult to accurately and efficiently produce, a structured design of the mesoscopic size of the brazed grinding wheel surface was carried out. Furthermore, simulation experiments were conducted to investigate the influence of the structured shape and distribution characteristics of the mesoscopic size on the residual stress in brazed welding. The results show that among the three types of structured grid shapes on the surface of grinding wheels, namely square, circular, and hexagonal, the circular structure produces the smallest residual stress during brazing; The comparison shows that within the variation range of structured grid spacing in the experimental design, the residual stress is the smallest when the grid spacing is 0.05mm; The comparison of residual stress between structured and unstructured brazed single abrasive grains indicates that mesoscopic structure can effectively reduce brazed residual stress.
