Process efficiency comparison of a sandwich-core sawblade and a conventional sawblade used in stone-machining

► Sawing efficiencies of two sawblades with diverse damping capacities were evaluated. ► The sandwich-core sawblade exhibited less active power consumption and specific wear rate. ► Higher force ratio of the conventional type sawblade indicated lower stability. ► About 10 dB less noise emission was achieved with the sandwich-core sawblade.
