Abstract
In the present age of increasing demand of productivity the theory of mechanization or automation of processes in order to achieve higher production rates with minimal of human input, there is need to develop innovative machinery to cater the above needs. Buffing operation is mainly done on the face of the components which is similar to polishing with the view to improve the surface finish of the components. The buffing operation is presently done by mounting an abrasive disk on the spindle of a hand grinder and feeding this rotating disk against the job surface.The parts produced by various machining operation such as turning, drilling ,milling etc. although fairly accurate in size, do not carry a very high degree of surface finish. In much industrial application, very high degree of surface finish is essential and desired.When very close dimensional accuracy is required in addition to high surface finish. As in polishing, the abrasive particles must be periodically replenished. As in polishing, buffing is usually done manually, although machines have been designed to perform the process automatically.This operation makes the surface smooth producing a high luster and mirror finish if desired. This is done with the use of buffing wheels and buffing compounds.Buffing is a finishing operation similar to polishing, in which abrasive grains are not glued to the wheel but are contained in a buffing compound that is pressed into the outside surface of the buffing wheel while it rotates. As in polishing, the abrasive particles must be periodically replenished. As in polishing, buffing is usually done manually, although machines have been designed to perform the process automatically.This operation makes the surface smooth producing a high luster and mirror finish if desired. This is done with the use of buffing wheels and buffing compounds. These compounds can be used to smooth andor shine metals, plastic, wood, and other materials. The names Buffing compound and polishing compound are used interchangeably and refer to fine abrasive fillers combined with greases which are formed into solid bars or liquid. This buffing operation removes scratches and makes the surface smoother. The edge, or face, of the wheel is the sanding block, which carries a thin layer of compound which is the sandpaper. Varying types of wheel are available, and the different grades of compound are scaled similar to sandpaper. The compounds are made from a wax substance which has the different abrasive powders added to it. When this hard block is applied to the edge of a spinning buffing wheel, the heat from the friction melts the wax, and both wax and abrasive are applied in a thin slick to the face of the wheel. This operation makes the surface smooth producing a high luster and mirror finish if desired. This is done with the use of buffing wheels and buffing compounds. Buffing can be divided into two steps; cut buffing and color buffing.These compounds can be used to smooth andor shine metals, plastic, wood, and other materials. The names Buffing compound and polishing compound are used interchangeably and refer to fine abrasive fillers combined with greases which are formed into solid bars or liquid.Buffing abrasives utilize the fine grades of aluminum oxide and silicon carbide abrasives. Buffing also uses fine graded alumina, Tripoli, iron oxide and chrome oxides abrasives that are carried by greaseless or tallow base materials forced into the buffing wheels( which acts as the abrasive carrier) or sprayed onto the buffs of automated systems.
