Principle and application of orderly arranging grain technology of superabrasives

The grinding tools arranged in order of superhard abrasives are the new varieties of the series of grinding tools,their working surfaces have grinding edges which are arranged in a regular pattern. Compared with the traditional abrasive tools, they have the advantages of large chip space, sharpness of grinding edge, small grinding force and low grinding temperature.They have a good application potential in high precision machining.Nevertheless, it's still a difficult problem to achieve arrangement of abrasive grains efficiently and accurately. Therefore, it is urgent to develop new layout technology to overcome these problems.This paper introduces the basic theory of orderly arrangement of abrasives, the structure, main manufacturing methods, research and development of abrasive tools, analyzes the influence of layout way on grinding performance, and forecasts its future development direction.
