Abstract

The invention discloses a method for preparing an electroplated diamond grinding wheel in which abrasives are arranged in an orderly manner. The coating is a pre-plated substrate; the diamond abrasive is placed on the surface of the pre-plated substrate and rolled so that the lower part of the abrasive is embedded in the blind hole to obtain the sand substrate; after the sand substrate is activated, electroplating is carried out to deposit on the surface of the grinding wheel substrate and in the blind hole Metal plating is obtained. The preparation method of the present invention realizes the regular and orderly arrangement of diamond abrasives on the surface of the grinding wheel substrate, and enhances the holding force of the coating on the diamond abrasives in the electroplating consolidation process; the obtained diamond grinding wheel has strong holding force on the abrasives, long service life, and abrasive The regular and orderly arrangement on the surface of the grinding wheel substrate improves the grinding quality and grinding efficiency; for diamond abrasives with the same particle size, the electroplating time is shortened to 20% to 55% of the traditional process, which improves the uniformity of the coating.

Description

technical field [0001] The invention belongs to the technical field of superhard material products, and in particular relates to a method for preparing an electroplated diamond grinding wheel in which abrasives are arranged in order. Background technique [0002] The electroplated diamond grinding wheel is a diamond grinding wheel made by electrodeposition. The working layer of the grinding wheel contains diamond abrasives and metal coatings, and the diamond abrasives are consolidated on the substrate by the metal coatings. During the electroplating process, metal ions are continuously precipitated on the surface of the cathode, and the abrasive is placed on the surface of the cathode, which is gradually covered by the deposited metal coating; after the thickening step, the diamond is finally fixed on the substrate to form a composite coating with grinding function. That is, an electroplated diamond grinding wheel is obtained. The electroplated diamond grinding wheel has a ...
