There is a super-sized coarse grinding and polishing will make naught

Determination of particle size diamond powder to make convenient and time-saving. Abrasive diamond powder mainly for freedom, particle size control is particularly important. As long as there is a super-sized coarse grinding and polishing will make naught. Powder particle size was measured in many ways, however, people's attention is to have a practical approach,  synthetic diamond the existence of a particle image automatic analysis device. According to the user's perspective powder, most accurate  abrasive grinding of the particle should be tested as to surround a particle diameter equal to the projected diameter of the circle. This means taking into account the particles from the particle count obtained may appear on the distribution curve peak, and to ensure that even in adverse conditions, yet they are not so coarse mixed product. The irregular shape of the direction of varying particle under a microscope to measure the longest axis and the true diameter circle, but it is very difficult. Use a commercially available television camera automatic device, experience has proved not reach sufficient accuracy;
