Preparation of rapid electroplating diamond wire saw

In order to improve the efficiency of preparing of diamond wire saw, sanding process is improved by chemical nickel plating on diamond micropowder surface, magnetization steel wire substrate.SEM, EDS and Gauss meter are used to study parameters influence on efficiency and durability.The experimental results show that the magnetic induction of substrate, diamond mass concentration and sanding time for wire saw preparation have important effect on the efficiency and durability.The best process parameters with magnetized substrate are:current density 5 A/dm², magnetic induction of substrate is 0.6 mT, diamond mass concentration 15 g/L, sanding time 30 s, temperature 45℃.Compared with untreated diamond and substrate, the sanding time can be decreased by 1/20 of the original process, thus improving total process by 81%, while wire saw still maintains high durability.
