Composite diamond dry grinding disc and preparation method thereof

The invention belongs to the technical field of grinding machining, and particularly relates to a composite diamond dry grinding disc and a preparation method thereof. The composite type diamond dry grinding piece comprises a diamond grinding layer, a woven mesh layer, a base body layer and a hook and loop fastener layer which are stacked in sequence. Diamond grinding materials are solidified in grids of the woven mesh layer and on the surface of the base body layer. The material of the diamond grinding material is consistent with that of the diamond grinding layer, and the diamond grinding material and the diamond grinding layer form an integrated structure; the woven mesh layer is made of a metal wire mesh; and the base body layer is made of a textile. According to the composite type diamond dry grinding piece, the diamond grinding material is fixedly bonded on the woven mesh layer and the base body layer, the bonding strength between the diamond grinding layer and the woven mesh layer and the bonding stren
