Surface 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.


During the grinding process, much of the dust is vacuumed up. Though some dust also goes into the air. Which is not only harmful to the worker but also the environment. Some of the advantages of dry grinding methods are following: A more shiny surface is obtained. It can also harden and condense the slab.

During the grinding process the workpiece material undergoes localized deformation, with this deformed material being displaced later. The localized deformation between the workpiece and the abrasive is called plowing. The plowed material slides — more on that later — on the grinding wheel surface prior to leaving the grind zone.


Therefore, grinding of the nonrotating and asymmetrical free-form surfaces cannot be processed through the above most common grinding methods. The slow tool servo technology with diamond turning is the most effective method for machining free-form surfaces on metal materials [ 20, 21 ].


Although you can grind concrete floors using either dry or wet methods, the trend today is to go dry. Not only is the dry method faster and more convenient, but it also doesn't leave behind the messy slurry that wet grinding creates. During the concrete grinding process, concrete floor grinders tend to create a huge amount of dust.


XRD method can also be used to detect the grinding damages. However, it is time consuming, expensive, and destructive when subsurface stresses need to be analysed. It is also important to emphasize that what we call a grinding damage or a "grinding burn" is a thermo-mechanical defect in which both thermal and mechanical loads play active roles.

Surface grinding is very effective because of the abrasive grinding wheel used. The wheel moves over the metal surface and removes material in minute quantities. Surface grinding processes include methods like vertical-spindle rotary, vertical swivel head, horizontal spindle single disk, vertical spindle, and horizontal spindle grinding.


The lapping process involves passing a part between one or two large flat-lap plates or platens in a carrier fluid containing an abrasive. Duval achieves a flat, polished surface by applying precision surface grinding methods that exceed the flatness of typical rough grinding, usually generating surface flatness within .0002 – .00005".


Precision grinding is a middle-ground between metal removal and part size control, and serves as the basis for creep feed grinding, slot grinding and high-efficiency deep grinding. In ultra-precision grinding, little to no actual cutting occurs, but sliding action from very fine grains rubs the workpiece surface to a high finish.


The electrochemical grinding process is a highly specialized method that combines surface grinding, chemistry, and fixturing, and has limited applications. OD grinding is used to shape the external surface of objects between the centers and excels at removing circular defects and restoring or creating roundness.
