Preparation method of electroplated diamond grinding wheel

Abstract

The invention discloses a preparation method of an electroplated diamond grinding wheel. According to the method, the grinding wheel with more diamond abrasive particles uniformly distributed in an abrasive layer can be prepared. The specific preparation process comprises the steps that a working face of a hub is pre-plated with a layer of Ni, then diamond abrasive particles and a hexadecyl trimethyl ammonium bromide surfactant are added into a nickel plating solution and stirred, the surfaces of the diamond abrasive particles can adsorb positive charges and are attached to a working face of a cathode hub, the diamond abrasive particles attached to the working face of the hub are embedded by continuously reduced metal nickel, and finally the abrasive material layer with nickel as a binding agent and diamond as an abrasive material is formed on the working face of the hub. According to the preparation method, a nickel and diamond abrasive particle co-deposition principle is utilized, the sand feeding efficiency of the electroplated grinding wheel is effectively improved, meanwhile, the phenomenon that abrasive particles are agglomerated in a plating solution and the Ni layer is avoided, the diamond abrasive particles in the abrasive layer are high in content and uniform in distribution, and therefore the preparation quality of the abrasive layer is improved, and the subsequent grinding performance of the grinding wheel is improved.

Description

technical field [0001] The invention relates to a preparation method of an electroplated grinding wheel, in particular to a preparation method of an electroplated diamond grinding wheel. [0002] technical background [0003] Electroplated grinding wheels have been widely used in the field of grinding processing due to their high grinding ratio and their ability to be used for complex profile grinding. The sanding method of the traditional electroplated grinding wheel often adopts the buried sand method and the falling sand method. The buried sand method is to bury the diamond abrasive grains on the working surface of the grinding wheel hub, and then perform electroplating to fix the sand. However, because the sand layer around the working surface of the hub is too thick , which seriously hinders the mass transfer and conductive process in the plating solution; the falling sand method is to place the diamond abrasive grains in the plating solution in a dispersed suspension st...
