The organic pigments are established by carbon chains and carbon rings.

MATERIAL REMOVAL MECHANISMS IN ABRASIVE FLOW …

The basic principle of AFM is that the abrasive and material removing effect of the grinding medium is in direct proportion to the speed of the abrasive. Following this principle, the conception of the workpiece holder determines the position of the highest speed of the grinding medium. The conception of the workpiece holder allows for an
