Abstract
Section titled “Abstract”Blades with concave segments and multi-layered segments were employed to cut large-sized granite (size: 2000 mm × 2000 mm × 2000 mm) using a diamond frame saw, which can accommodate 80-120 blades (size: 4000 mm × 180 mm × 3.5 mm). Cutting force was determined by a Kistler dynamometer, and diamond segment wear was examined by scanning electron microscopy and Keyence microscopy. Sawing performance was evaluated based on slab quality, radial wear, cutting force (force ratio), and slab production rate. Compared with the blade with multi-layered segments, experimental results showed that the blade with concave segments produced better slab quality; lower cutting forces, force ratio (normal force/horizontal force), and radial wear (tool consumption); and higher slab production rate. Experiments indicate that blades with concave diamond segments are more suitable for the diamond frame saw to cut granite.
