A composite electroplating process was used to electroplated diamond wire saw. Piano wire was chosen as the plated core of the electroplated diamond wire and the diamond size was 400# . Putting the wire into diamond abrasives and Watt-type solution were used to manufacturing the diamond wire saw. The coating thickness and morphology of the diamond were analyzed by microscope and stereomicroscope. The results show that the current density of the Ni-diamond composite electroplating in the range of 2.0A/din2 and the time of the Ni-diamond composite eleetrophting was 20rain, diamond abrasives will be distributed well and the coating had better adhesion to the substrate. The optimum process parameters of manufacturing the diamond wire saw were con-firmed.
