EDM grinding wheel dressing technology is first proposed a low-cost, practical

Discharge traditional diamond wheel dresser dressing as a non-contact technique is based on the power of physics, thermal melting and vaporization mechanism removing wheel binder, thus avoiding direct action and dressing tool superhard diamond abrasive contact with a promising trimming technologies. However, due to the discharge electrode with a conductive requirements can only be trimmed diamond wheel base brass or cast iron base and other conductive type diamond grinding wheel. For  Abrasive grinding wheel  resin bond and vitrified diamond grinding wheel, the traditional discharge trimming technology can not effectively applied. This paper proposes a method of spark trimmed to resin bond diamond grinding wheel, for example, for weakly conductive and non-conductive grinding wheel dressing.  Polycrystalline diamond  wheel dressing technology is first proposed a low-cost, practical superabrasive grinding wheel technology. EDM able erosion conductive diamond grinding wheel bond materials, mainly due to the spark discharge path between the poles of the instantaneous amount of heat generated, the instantaneous wheel surface temperature can bond the conductive material is melted or vaporized to form a discharge pit prominent grain, in order to achieve a conductive grinding wheel dressing.
