Hot working includes casting, forging and welding. Cold working, also known as metal cutting process, including tool cutting process (which has turning process, drilling and boring process, planing, inserting, broaching, milling process, abrasive cutting process; the processing of gear teeth). The following are briefly introduced. (A) casting The casting process is to pour liquid metal into the mold, to be cooled to obtain a certain shape and sex of the casting. This is the method of molding metal in the liquid state. Casting can produce billet blanks of complex shapes, especially complex internal cavities, with unlimited size and weight. Both single-piece production, can also be mass production, the use of most of the material from a wide range of sources, low prices, but also available scrap and waste parts, so the cost is low. Castings and parts of the shape and size close to the processing allowance is small. Casting...
