The invention relates to a preparation method of an
electroplating diamond fret saw, comprising the following technological processes: 1. roughening
processing is carried out to
micrometer diamond particles in advance, nanometer
diamond powder is added in cationic
surface active agents according to the proportion of 1 : 3 by
mass ratio, so as to prepare uniform and stable nanometer diamond
powder suspending liquid, plating solution is arranged in an
electroplating tank, after the weighted nanometer diamond
powder suspending liquid is mixed with the
micrometer diamond particles according to the proportion of 1 : 3 by
mass ratio, and then the mixture is added in the plating solution, the plating solution is circulated continuously, and
nickel aminosulfonate is main material in the plating liquid, and boracic acid and
nickel chloride are additionally added, and a magnetic stirring device is arranged in the
electroplating tank; 2. a steel wire continuously and uniformly passes through the electroplating tank, under the action of
electrical current,
nickel ions move to
cathode from
anode, so as to drive the nanometer diamond powder and the
micrometer diamond particles to move to the steel wire, so as to lead the steel wire to be plated with the nanometer diamond powder and the micrometer diamond particles, meanwhile, chemical nickel-plating is carried out to the steel wire; 3. after the steel wire is separated from the electroplating tank, wires are wound up after being cleaned and dried. The method can continuously and quickly produce electroplating diamond fret saw, and the production efficiency is high.
