Abstract

This is a project to develop or adapt machinery for the manufacture of diamond sanders. The procedure chosen was that of adapting a flexography printing machine used in the manufacture of plastic labels for use in liquids containing suspended, abrasive particles in a plastic substrate. Variables to be controlled include the thickness of the layer to be deposited, the adherence of the deposit, the proportions in the makeup of the liquid suspended with abrasives, the speed of drawing the coil so as to enable proper drying of the deposit, and in particular, the choice of the suspended liquid and the quality of the diamond powder, seen through characteristics such as the histogram of the narrow overflow, and the repetition of the characteristics in various batches, etc. (AU)
