Grinding wheels are self-sharpening to a small degree; for optimal use they may be dressed and trued by the use of wheel or grinding dressers. Dressing the wheel refers to removing the current layer of abrasive, so that a fresh and sharp surface is exposed to the work surface. Trueing the wheel makes the grinding surface parallel to the ...
A man grinding on metal using an angle grinder, causing a lot of sparks. Grinding is a type of abrasive machining process which uses a grinding wheel as 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 cut-off saws

Surface grinding is done on flat surfaces to produce a smooth finish.. It is a widely used abrasive machining process in which a spinning wheel covered in rough particles (grinding wheel) cuts chips of metallic or nonmetallic substance from a workpiece, making a face of it flat or smooth.
The handstone of a rotary quern is much heavier than that of saddle quern and provides the necessary weight for the grinding of unmalted grain into flour. In some cases the grinding surfaces of the stones fit into each other, the upper stone being slightly concave and the lower one convex. Rotary hand quern at the Estonian Open Air Museum
Grinding wheel wear is an important measured factor of grinding in the manufacturing process of engineered parts and tools. Grinding involves the removal process of material and modifying the surface of a workpiece to some desired finish which might otherwise be unachievable through conventional machining processes. [ 1 ]
