Dry Cutting and Grinding is Risky Business

cutting and grinding can get deep into the lungs. Most concrete and masonry products contain large amounts of sand. When you inhale the dust, silica particles scar your lungs, causing a disabling, irreversible, and incurable lung disease called silicosis. The good news is that silicosis is 100% preventable. You can work with silica-containing materials

Forces and Energy in Circular Sawing and Grinding of Granite

An investigation is reported of the forces and energy in circular sawing and grinding of gray granite. Measurements were made of the forces and power over a wide range of sawing and grinding conditions. Calculated tangential force components were found to be much different than the measured horizontal force components for sawing, but the two forces were almost identical for grinding.

For example, a smooth stone will not grind as well as a rough stone and stones that wear quickly will release larger amounts of stone particles into the food that can effect dental health. The most common stones used in Mesoamerica before European contact were granite, rhyolite, andesite, quartzite, sandstone, and limestone.

The Effects of Machining Parameters on the Position of

The effects of the machining parameters on the relative position of the resultant force were analyzed in circular sawing of granite with a diamond segmented blade. The horizontal and vertical force components and the power were measured. Calculated tangential and normal force components were subsequently used to calculate the relative position of resultant force besides the horizontal and
