The utility model discloses a multilayer different particle size composite
grinding wheel relates to
abrasive tool technical field, aims at solving the problem of traditional multilayer
grinding wheel
abrasive waste, easy separation between
layers. It includes annular inner aluminum core and at least two
layers annular outer sand ring, and the outer circle surface of inner aluminum core is equipped with multiple evenly distributed tenons in the axial direction, and the inner circle surface of outer sand ring is equipped with matched mortises, and after the
mortise and tenon of both are nested, they are fixed as an organic whole with high-temperature resistant
ceramic base
adhesive, the mesh number of outer sand ring
abrasive increases gradually from bottom to top, and the axial thickness decreases synchronously to form gradient, and the surface of inner aluminum core is treated by
anodic oxidation. The design reduces the consumption of abrasive with aluminum core, improves the stability between
layers with double fixing, adapts to the requirement of rough
grinding to fine grinding with gradient, improves
processing efficiency with one clamping, prolongs the life with aluminum core heat dissipation and
oxide film protection, and is suitable for precision parts multi-roughness grinding.
