A machine for dry grinding gears

Italy-based Samputensili S.p.A. unveiled a machine that eliminates the need for cutting oils when manufacturing gears, thereby reducing grinding costs. During grinding, oil-based lubricants cool the workpiece, as well as reduce friction and help evacuate chips. On the downside, however, oil use accounts for a significant amount of a grinding operation's total cost. Expensive equipment is required to supply, chill, catch and wash away oil in grinding processes. In addition, Samputensili estimates that oil-treatment equipment accounts for 75 percent of the energy consumed by a grinding machine.
