Abstract: An abrasive product with a concave-convex structure includes laminated three planar layers and an abrasive layer with a concave-convex structures located on an upper surface of the three planar layers. The abrasive layer with a concave-convex structure is an array of abrasive blocks, and a groove serving as chips discharging groove is formed between each two adjacent abrasive blocks. The abrasive block includes a binder and abrasive grains distributed in the binder.
