Grinding (abrasive Cutting)
Grinding is a type of abrasive machining process which uses a grinding wheel as Cutting tool (machining), cutting tool. A wide variety of machines are used for grinding, best classified as portable or stationary: * Portable power tools such as angle grinders, die grinders and abrasive saw, cut-off saws * Stationary power tools such as bench grinders and abrasive saw, cut-off saws * Stationary hydropower, hydro- or human power, hand-powered grindstone (tool), sharpening stones Milling practice is a large and diverse area of manufacturing and Tool and die maker, toolmaking. It can produce very fine finishes and very accurate dimensions; yet in mass production contexts, it can also rough out large volumes of metal quite rapidly. It is usually better suited to the machining of very Hardness, hard materials than is "regular" machining (that is, cutting larger chips with cutting tools such as tool bits or milling cutters), and until recent decades it was the only practical way to mach ...
