Metal parts surface processing:
1, spray paint processing: hardware factory in the production of large pieces of hardware are used in the process of painting, through the spray paint processing to avoid rust, such as: daily necessities, electrical appliances, handicrafts, etc.
2, plating: plating and metal processing most common processing technology, through the modern technology of metal surface plating to ensure products for long time use does not occur mildew, embroidery, electroplating processing common: screws, stamping parts, batteries, car parts, decorated with a small goods and so on.
3, surface polishing: surface polishing processing in general in the daily use, through the surface of the metal products, such as: we produce a comb, comb is made of metal parts, so that the edge of the comb is very sharp, we will have a sharp part of the edge angle into smooth face, so that the use of the process will not cause damage to the human body.
Turning the outer circle is the basic method of machining the machining of the Chinese and foreign surfaces. In the general machinery factory, lathe machine accounted for about *0% of total units. Turning is the main method of rough machining and semi finish machining various kinds of materials, but also the final finishing method of various materials.
When a small batch production, turning the outer round surface is generally carried out in ordinary lathe. Large quantities of production, a wide range of semi-automatic lathe or automatic lathe. Large plate parts should be processed in a vertical lathe. Large long axis parts need to be processed on a heavy-duty horizontal lathe.
Cylindrical turning face features are: 1, the tool is simple, manufacturing, grinding, and convenient installation; 2, the cutting process is stable, little fluctuation of cutting force, is conducive to the use of high cutting speed, improve productivity; 3, machine tool general can in one clamping in machining circle and the end surface and in the hole, the thread and the chamfer abroad etc.. The mutual position accuracy of each surface is easy to be ensured; 4, suitable for the fine processing of non-ferrous * * *:* *:*@***********************6
