Abstract

The invention discloses a superhard grinding tool and a preparation method thereof. The superhard grinding tool comprises a grinding tool substrate and a grinding material, wherein the grinding material is solidified on the grinding tool substrate through a plating layer, and the plating layer comprises the following components by mass percentage: 10% to 20% of Cr, 5% to 15% of P, and the balance of Ni. According to the superhard grinding tool provided by the invention, the chemical metallurgy binding of the grinding material, a plating metal alloy and the grinding tool substrate is realized, the holding strength of the grinding material is greatly improved, the problems of the existing plating superhard grinding tool that the grinding material is easily shed or the plating layer is peeled off under the efficient grinding conditions, resulting in the overall failure of the grinding tool are solved, and the service life of the grinding tool is prolonged; the chip space of the grinding tool is large, and the plugging is not easily generated; the quality is stable, the service life is long, and the superheard grinding tool is suitable for being popularized and applied.

Description

technical field [0001] The invention belongs to the technical field of grinding tools and abrasives, and in particular relates to a superhard material grinding tool, and also relates to a preparation method of a superhard material grinding tool. Background technique [0002] Superhard material products have the advantages of high strength, long service life, and high machining accuracy. Therefore, as the preferred tool, they play an irreplaceable role in the field of grinding difficult-to-machine materials. The holding strength of the bond material to the abrasive directly affects the performance of the superhard abrasive tool. The commonly used bond materials mainly include metal, resin and ceramics, and the holding force of the metal bond to the abrasive is relatively high. In metal bond products, the electroplating method is simple in preparation process and low in investment. It mainly uses the metal ions of the electroplating solution to obtain electrons at the cathode ...
