Usage of Abrasive Grains with Controllable Shapes as Means of Grinding Wheels Operation Stabilization

In general the efficiency of the grinding process depends on the effectiveness of the cutting ability of each individual grain. The better each grain works, the higher the performance of grinding is. The grain geometry which is favorable for a particular case may provide for the most efficient work of the grain. In turn, the geometry of the grain is determined by two main factors: the shape and its position in the tool body (grinding wheel). In Volzhsky Polytechnic Institute (branch) of Volgograd State Technical University in the SEC “Volzhsky Scientific-Research Institution of Abrasive Grinding” the new technology of the production of an abrasive tool was made. It allows both stabilizing its operation and managing its performance at the manufacturing stage by improving of the classification process of grinding grain, not only by its size but also by its the shape.
