Diamond wire saw machine electroplating method is used to manufacture the beaded metal, which is the beaded matrix and the diamond bond. Therefore, its role is not only to produce a firm mosaic bond to the diamond, but also to withstand the friction and impact of rocks countless times in use, which requires the coating metal to have high hardness, wear resistance and toughness. Experiments have proved that Ni-Co The alloy coating can have both of these characteristics, so Ni-Co alloy is mostly used as the coating metal for electroplating beads.
The coating metal is used as a binding agent to ensure the service life of the beads, and to make the diamond get a better edge, that is, to take into account the life and efficiency. Therefore, for the single-layer diamond beads, the thickness of the coating should be moderate. If the coating is too thin, the diamond will be buried less, and the bonding fastness will be poor. During the use process, the diamond will fall off if it fails to function fully, and the life of the diamond wire saw machine will be too short; on the contrary, if the coating is too thick, the diamond will almost completely fall off. If it is buried in the coating, the diamond will have no edge, and the sawing efficiency is very low. Until the rock continuously rubs the coated metal and wears it to a certain value, the diamond wire saw machine has a normal cutting speed. Therefore, the thickness of the coating should be appropriate. It is generally considered that the thickness of the coating is equivalent to 2/3 of the average particle size of the plated diamond. That is to say, 1/3 of the diamond is exposed outside the coating metal.
