New developments in diamond wheel



Diamond grinding wheel is grinding carbide, glass, ceramics, precious stones high brittle materials effects tools. In recent years, with high-speed grinding ultra-precision grinding technology developed rapidly, put a higher demand on the grinding wheel, ceramic resin bonded grinding wheel has been unable to meet production needs, because of its of metal bonded grinding wheel, high strength, good formability, long life and other significant characteristics of the production has been widely used. Metal  Polycrystalline diamond wheel manufacturers in different ways according to a major, plating two types. In order to give full play to the role of super abrasive abroad from the 20th century, the early 90s with a high temperature brazing  synthetic diamond  to develop a new wheel, ie single high temperature brazing grinding wheel, the current Ceramic diamond grinding wheel, vitrified bond diamond wheel with diamond and vitrified common characteristics, and general corundum, silicon carbide grinding wheel compared to its grinding force, grinding temperature is relatively low, the wheel wear is relatively small; can be adapted the role of various cooling fluid; grinding wheel is good shape retention, high precision grind the workpiece; wheel has more pores, grinding and heat conducive chip, clogging, easy to burn the workpiece; wheel good self-sharpening, finishing a long time interval, trimming easier. Therefore, vitrified diamond grinding wheel used in some foreign countries is increasing. ceramic diamond wheel of this sand is still in research and development phase.
