ABSTRACT:
A method for sawing hard material with circular abrasive disc saws of the kind having secured to the periphery of the disc arcuated cutting segments of bonded diamond abrasives, in which conventional speed of rotation of the abrasive disc, cutting depth of the disc and longitudinal feed are selected for abrasive disc. On the arcuated cutting segments of bonded diamond abrasives an effective total peripheral cutting surface consisting of the sum of the cutting surfaces of the single arcuated segments is provided having along a peripheral circumference an optimum average number of cutting points of the bonded diamond abrasive per one millimeter width as determined as a function of the ratio of the selected longitudinal feed and the product of an average incision depth made by a single diamond point.
