The electroplating of beads is basically the same as that of ordinary diamond electroplated products. The slight difference is that the beads are smaller, and how to improve efficiency should be considered. Generally, the bead base can be put on a fixture, the two ends are tightened with nuts, and the unplated parts are wrapped with plastic cloth for insulation. The number of substrates to be worn in a string can be determined according to the size of the electroplating tank. If the tank allows, hundreds or more can be plated at the same time. In addition, sanding, thickening is best carried out in different plating tanks. Sand to horizontal rotation beads, and thickening can be placed vertically, can be plated more. As the bonding agent, the coated metal must not only ensure the service life of the beads but also enable the diamond to obtain a better edge. That is to consider both life and efficiency, so for single-layer diamond beads, the thickness of the coating should be moderate. If the plating layer is too thin and the diamond is buried too little, the bonding fastness will be poor, and the diamond will fall off if it fails to fully play its role during use, and the life of the wire saw is too short. On the contrary, if the plating layer is too thick and the diamond is almost completely embedded in the plating layer, the diamond has no edge and the sawing efficiency is too low. Until the rock continues to rub the coated metal and wear it to a certain value, the wire saw will have the normal cutting speed. Therefore, the thickness of the coating should be appropriate. It is generally believed that the thickness of the coating is equivalent to two-thirds of the average particle size of the diamond plate. That is to say, one-third of the height of the diamond is exposed to the coating metal.
