Problems solved by technology

However, the current electroplating method can only produce coarse grinding wheels with a diamond abrasive particle size of more than 40 μm. When the diamond abrasive particle size is finer, only by the gravity of the abrasive, the fine-grained abrasive is suspended in the electroplating solution, and the sedimentation speed is too slow. The deposition is fast, so that the ratio of metal bond to abrasive in the grinding layer of the manufactured grinding wheel cannot be controlled, forming a metal hard shell or creating voids, and the quality cannot be guaranteed

Abstract

The invention discloses a method for producing a grinding electroplated diamond wheel. The method comprises the steps of: 1, preparing an electroplating bath; 2, pre-treating before plating; 3, pre-plating, wherein the current density is 1.2-1.8A / dm<2>, and the thickness of a pre-plating layer is 7-10micrometers; 4, magnetically sand feeding, namely applying magnetic induction intensity of 400-1000mT on a plating surface of a grinding wheel base body so as to absorb a diamond abrasive through the plating surface of the grinding wheel base body, and depositing an electroplating layer through electrifying, wherein the sand feeding current density is 0.5-0.8A / dm<2>, and the thickness of the plating layer is 15% of the average particle size of the diamond abrasive; 5, thickening, wherein the current density is 1.6-2.0A / dm<2>, and the thickness of the thickened plating layer is 65% of the average particle size of the diamond abrasive; and 6, treating after the plating so as to obtain the grinding electroplated diamond wheel. By utilizing the method for producing the grinding electroplated diamond wheel, the abrasive with fine granularity can be uniformly solidified on the plating surface, and the produced grinding wheel has good shape retention performance and satisfies grinding requirements on high precision and high efficiency.
