Problems solved by technology

However, in order to increase the holding force of the coated metal to the abrasive, the thickness of the coating must be increased, which reduces the exposed height of the abrasive grains and reduces the chip space, which leads to the problem that the grinding wheel is prone to clogging, the heat dissipation effect is poor, and the surface of the workpiece is prone to burns.

Abstract

The invention discloses an abrasive feeding method for an electroplate grinding wheel. The method comprises (1) a step of surface treatment of an abrasive; (2) a step of abrasive distribution, wherein the abrasive after being treated and a magnetic fluid containing a plating solution are mixed uniformly to form a suspension liquid, and then the magnetic fluid carrying the abrasive is controlled by magnetic field changes to motion on the surface of an electroplate grinding wheel matrix, thus completing distribution of the abrasive on the surface of an electroplate grinding wheel matrix; and (3) a step of abrasive fixation. The electroplate grinding wheel matrix is a steel matrix, a copper matrix, a bronze matrix, an aluminum matrix, an aluminum alloy matrix or a cemented carbide matrix. According to the method, the precision of abrasive distribution is improved and the strength between the abrasive and the matrix is enhanced. The grinding wheel prepared by the method has a good heat dissipation effect and a long service lifetime, and causes no surface burns of workpieces during machining processes.

Description

technical field [0001] The invention relates to a method for preparing an electroplated grinding wheel, in particular to a method for accurately sanding an electroplated grinding wheel. Background technique [0002] Electroplated grinding wheels generally include a substrate and a grinding layer arranged on the outer layer of the substrate. The grinding layer is an abrasive / nickel composite coating. According to the type of substrate, it can be divided into three types: metal base, ceramic base, and resin base. High efficiency, high grinding efficiency and long service life have been widely used in production. In addition, due to the characteristics of diamond abrasives (high hardness, high compressive strength, and good wear resistance), it becomes an ideal tool for grinding hard and brittle materials and cemented carbide in grinding processing. High, good roughness, less consumption of abrasive tools, long service life, and improved working conditions, so it is widely use...
