Introduction on Polish of Aluminum profile:
Polishing refers to the use of mechanical, chemical or electrochemistry to reduce the surface roughness of the workpiece in order to obtain the processing method of the bright, flat surface. It is used to process the surface of the workpiece with polishing tools and abrasive particles or other polishing medium.
Polishing can improve the size precision of the workpiece or geometric accuracy, but in order to get smooth surface or bright luster for the purpose, sometimes also used to eliminate the gloss (extinction). The polishing wheel is usually used as a polishing tool. Polishing wheel general use multilayer canvas, felt or leather fold into the system, the two side with a metal powder compact, its rim coated by powder abrasive such as uniform mixture of polishes and grease.
Chemical polishing:
The electrochemical potentials of each component of the metal sample surface are different, forming a lot of microelectric potential, which can produce an inhomogeneous solution in the chemical solution. Surface in the process of dissolving sample surface cause a layer of oxide film, the sample surface bulge because mucous membrane is thin, the dissolution of metal expansion speed slower, after polishing surface is smooth, but form a small ups and downs of the waveform, can't meet the ideal requirements. Use under low and medium magnification microscopy, the small fluctuations within a general vertical identification capability of the objective, can still observe the organization is clear.
Mechanical polishing:
Mechanical polishing depends on the grinding and rolling of very small polishing powder, removing the very thin layer of metal on the test surface. It is difficult to remove the deep grinding marks on the front of the polish before polishing. Because if the grinding crack throw away, is bound to add thick polishing liquid, lengthening the time or aggravating when polishing pressure, cause the grinding surface metal flow and disrupt, specimen deformation of ground surface layer thickening, make some of the alloy phase loss. In particular, the oxidation on the surface of the mill will be more severe, affecting the organization's observation. So the specimen of mechanical polishing only allows the fine grinding of a single direction after the fine grinding.
1: Polishing can improve the performance of workpiece against fatigue and corrosion resistance.
2: It can also be used as an intermediate process to provide paint, electroplating, etc.
3, polishing abrasive machining method is a kind of widely used, metal and non-metallic materials products, precision mechanical and electrical products, daily necessities, polishing processing can be used to improve the surface quality.
4, polishing usually does not use special equipment, tool box processing method also is relatively simple, cost is low.
5. Because the polishing wheel is elastic, it can match the surface of the surface, easy to achieve surface polishing, and make it easy for the mold cavity to be polished.
6, can reduce the surface roughness value not only to keep or improve the machining accuracy due to the polishing wheel and workpiece, no rigid motion relationship between polishing wheel and elastic, therefore cannot guarantee from uniform removal of material of workpiece surface, just remove the traces left by the before, for the surface of the light.
7, the labor condition is inferior polishing at present much is manual operation, the work frequency is heavy, the abrasive grain that splash, medium, microchip and so on pollute environment. To improve the working conditions, the abrasive belt grinder can be used to polish the grinding machine to replace the polishing wheel.
