Dust collectors are used in many processes to either recover valuable granular solid or powder from process streams or to remove granular solid pollutants from exhaust gases prior to venting to the atmosphere.
Lathes and turning centers cut a rotating part with a stationary cutting tool. The tool moves parallel and perpendicular to the workpiece axis to provide the desired finished shape.
Milling machines move a clamped workpiece into a fixed, rotating cutter; or move the cutter itself into a stationary workpiece. There are two basic configurations: vertical and horizontal.
