Grinding is a machining process specially indicated for finishing operations in hard materials, in order to obtain low surface roughness (Ra 0.1 μm to 2μm) and tight tolerances.The cutting tool is the grinding wheel which is formed by abrasive particles attached in a bond.
Read OnAdditional surface finishing passes typically take place afterward — in particular, a "spark-out" pass relieves some of the stress on the machine tool and uses plowing to impart a better surface finish and size tolerance. Precision grinding is a middle-ground between metal removal and part size control, and serves as the basis for creep ...

Read OnSuperfinishing is a chip removing machining process. But not one that is comparable to any other. In contrast to the classic lathe turning and grinding methods, there is full surface contact between the tool and the workpiece. This is precisely the feature that produces the unique characteristics of a perfectly machined surface.

Read OnThe idea was to represent rough or first machining operation by one triangle (triangle symbolizes the turning cutting tool). Two triangles meaning two passes of the tool and hence finer finish. Normally four triangles require a grinding operation and a roughness of between 32-16 microinches RMS.
Read OnGrinding. Machining is one bulk material removal process (i.e. high MRR). Thus it is economical and suitable to give proper size and also for semi-finishing. Grinding has low material removal rate and is preferred only for finishing. Accuracy and tolerance achieved by conventional machining operations are not so good.
Read OnSurface finish refers to the process of altering a metal's surface that involves removing, adding, or reshaping. It is a measure of the complete texture of a product's surface that is defined by three characteristics of surface roughness, waviness, and lay. The surface roughness is the measure of the total spaced irregularities on the surface.
Read OnSpecification of grinding wheel: Grinding wheel is the main component of the grinding machine. It is responsible for the whole machining process. The proper selection of grinding wheel is very important and the selection of the grinding wheel depends on various factors such as a material of the work piece, finishing requirements etc.
