Generation and prevention of cracks in slurry pump impeller grinding:
After the slurry pump impeller is processed, if the residual stress on the surface layer exceeds the strength limit of the material, cracks will occur on the surface of the slurry pump impeller. Many grinding cracks may not be on the outer surface of the workpiece, but are hard to see with the naked eye The phenomenon under the surface layer, the direction of these cracks is perpendicular to the grinding direction, or meshed, and the occurrence of cracks often occurs simultaneously with processing burns.
