The strength of the aluminum alloy and steel, but less than stainless steel, aluminum alloy density is only 1/3 of the stainless steel, the light and strong, toughness is dye-in-the-wood space level of metal, widely used in industry and in the manufacturing of articles for daily use. Aluminium alloy workpiece using CNC machine tools Precision cutting grinding is made. Surface after sand blasting process. It is worth mentioning that both the frame is aluminum magnesium alloy material.
Current precision and ultra-precision machining accuracy from micron die casting parts to sub-micron and nanometer, in car, home appliance, IT electronic information and the field of high and new technology are widely used military and civilian industry. At the same time, the precision and ultra-precision processing technology has promoted the development of machine Machinery, mold, hydraulic, electronics, semiconductor, optics, sensor and measurement technology and the rapid development of the metal processing industry. According to the machining accuracy, mechanical processing can be divided into general processing, precision processing and ultra-precision processing. But the line is along with the progress of the processing technology, and constantly changing, today's precision machining may be tomorrow's general. Precision machining solutions Should the problem, one is the machining accuracy, including the shape tolerance, dimensional accuracy and surface condition; Second, machining efficiency, good machining accuracy can be achieved with some processing, but difficult to obtain high machining efficiency.
Precision machining, including microfabrication and super fine Processing, such as finishing machining processing technology. The traditional precision machining method with abrasive belt grinding, precision cutting, honing, precision grinding and polishing, etc.
Precision cutting, also called the diamond cutting tool (SPDT), with high precision machine tools and machining single crystal diamond tool, mainly used for copper, aluminum and other unfavorable grinding processing of soft metal precision machining, such as the computer with the drum, and disk and home Rate of laser with metal mirror, higher than general machining precision of 1 ~ 2 level. Honing head of honing, oil sand, under a certain pressure reciprocating motion along the workpiece surface, after processing the Investment casting parts surface roughness can reach Ra0.4 ~ 0.1 mu m, a Good to Ra0.025 mu m, are mainly used for processing iron and steel, and should not be used for processing small hardness and good toughness of non-ferrous metals. Precision polishing abrasive belt is the blended fabric of with abrasive abrasive to machining of workpieces, belong to our abrasive grinding van Domain, high productivity, good surface quality, widely used, etc.
Precision grinding and super precision machining of aluminum alloy parts. Precision machining, including microfabrication, superfine processing and finishing processing, finish machining processing technology, etc. Microfabrication technology refers to the manufacturing of small size parts processing technology; Superfine processing technology Refers to manufacturing ultra-small size parts, processing technology, which is in view of the integrated circuit manufacturing requirements, and that due to the tiny size, its precision is by removing the size value, rather than using the ratio of size and size error .
Finishing process generally refers to the lower surface roughness and increase die casting parts mechanical processing method, the mechanical properties of surface layer can't focus on improve the machining accuracy, the typical machining method are honing, grinding, super finishing and a chipless machining. In fact, these processing Method not only can improve the quality of surface, and can improve the machining accuracy. Finishing machining is put forward in recent years a new terms, it is corresponding to light the whole processing, is both to reduce the surface roughness and improve the surface mechanical properties, To improve the machining accuracy (including size, shape, position precision) processing method.
