Resumo
The sawing of granite blocks using multi-blade gangsaws and an abrasive mixture is one of the most complex operations in the rock transformation industry. The surface quality of the finished slabs is the main determinant of the volume of material to be removed in subsequent polishing operations, thus affecting the product's final cost. Measurements carried out on five types of siliceous dimension stone slabs showed differences in sawing speed and industrial process costs. The roughness values obtained, together with the test results for the uniaxial compressive strength, Amsler wear, sawability, coefficient of dynamic friction and petrographic analysis, showed that the rock texture has the most important influence on the production cost of polished slabs.
