Reducing tool wear in abrasive cutting

The abrasive Cut-Off with stationary or hand-operated machines for cutting or grinding metal is still a very common procedure in many enterprises. Because of the relatively low price of the tool 'cut-off wheel' little attention is paid to the life-time of the grits. Since it is possible to obtain shape-defined grits for the production of grinding wheels an experimental study was carried out producing and testing such cutting-wheels. It has been shown that it is possible to reduce the wear of the wheel by means of using shape-defined grits. The following paper describes selected experimental studies and their results.
