Study on magnetic-field-based abrasive grains patterning for electroplating diamond wire saws

Abstract

In this study, the magnetic field-based abrasive grain patterning for the production of electroplating diamond wire saws was studied. During the manufacturing process of the electroplating diamond wire saw, a permanent magnet was used to perform magnetization of the carbon steel wire. In addition, the following two methods were further used to perform partial degaussing on the carbon steel wire. The first method refers to the laser degaussing method, and the second method refers to the electromagnetic degaussing method, followed by performing electroplating on the carbon steel wire that has undergone the degaussing process. The impacts of these two methods on the magnetization characteristics of the carbon steel wire were studied, the magnetic induction strength of the zone of degaussing, range of the zone of degaussing, production speed, etc., in order to reach a conclusion on the methods for degaussing of a carbon steel wire. In this study, a nanosecond laser with a wavelength of 355 nm was used to perform a partial degaussing treatment on the surface of a magnetized carbon steel wire. When the laser fluence is 11.56 J/cm2, the controlled degaussing region of the abrasive grains could be minimized to 83.8  μm.
