FIELD: metallurgy.
SUBSTANCE: heating is carried out by high-frequency currents, hardening, low tempering and sulfochroming of an assembled plunger pair, at the same time the plunger is given reciprocal and rotary motion relative to a bushing with the amplitude equal to the length of the maximum plunger travel with the help of a driving wheel installed on a shaft and a disc installed at the second end of the shaft at the angle to its axis, on the lateral side of which there is a hinged joint connected via a traction rod with a plunger leash by means of a pressing grip.
EFFECT: higher quality of sulfochroming of plunger pairs.
