| titleOfInvention | A kind of porous electroplating bond grinding wheel and preparation method thereof |
| abstract | The invention discloses a preparation method of a porous electroplating bond grinding wheel, which comprises 1) disposing a nickel electroplating solution; 2) substrate insulation, degreasing and oxidation pretreatment; 3) taking the substrate as the cathode and the nickel rod as the anode, Electroplating under the action of external direct current; 4) Pre-impregnation: The substrate with the nickel-abrasive-metal insoluble compound abrasive layer is immersed in a dilute acid solution for preliminary corrosion to obtain a porous electroplating bond grinding wheel. The grinding wheel of the present invention can generate new micropores on the surface of the abrasive layer with the wear of the electroplating binder on the surface of the abrasive layer, thereby continuously maintaining the porous structure of the surface of the abrasive layer. Since the inside of the abrasive layer is not a porous structure, the strength of the abrasive layer can be kept unchanged, and the deformation of the abrasive layer caused by the reduction of the strength of the abrasive layer can be avoided. |
