Diamond rope saw electroplating process used to manufacture beads of coated metal and coating thickn

The coated metal of diamond wire saw is the matrix of diamond. So its role in addition to the strong on diamond Mosaic combination, at the same time to countless times in using rock friction and impact, which requires the coating metal has higher hardness, abrasion resistance and toughness, experiments prove that Ni - Co alloy coatings can be both of these features, so the plating beads to choose Ni - Co alloy plating metal.

As a binding agent, the coated metal should not only guarantee the service life of the bead, but also make the diamond get a better edge, that is, give consideration to both life and efficiency. If the coating is too thin and the diamond is buried in less, the bonding fastness is not good, and the diamond does not fully play its role in the process of use will fall off, and the life of the rope saw is too short. On the contrary, if the plating layer is too thick, the diamond is almost completely buried in the coating layer, then the diamond has no blade, and the cutting efficiency is very low. Only when the rock is constantly rubbing the coating metal, which makes it wear to a certain value, can the rope saw have the normal cutting speed. The thickness of the coating should be appropriate. Generally speaking, the thickness of the coating is equal to 2/3 of the average particle size of the gold-plated corundum.
