Machine tool cast casts the cast of principle machine tool that the method chooses to still call lathe bed cast, cast of machine tool lathe bed, cast of large lathe bed, cast of heavy-duty machine tool, cast of body of double housing planer, disappear cast of modular lathe bed. Characteristic of cast of numerical control planer-type milling machine: 1) appearance of cast of numerical control planer-type milling machine is OK very complex, can acquire the part of the complex lumen that machining realizes hard especially. 2) the dimension of cast of numerical control planer-type milling machine and weight are unlimited, can go to ten meters greatly, weigh hundreds tons, small to a few millimeter, a few grams. 3) production lot of cast of numerical control planer-type milling machine is unlimited, but odd, also but big batch production. 4) cost cheap, resource conservation. As a result of close of the appearance of cast and spare parts, dimension, because this saved material and treatment man-hour. Especially nicety is cast, but direct casting gives a part, it is the significant progress direction that does not have cutting treatment less. 5) wearability of cast of numerical control planer-type milling machine and disappear shake sex are good. As a result of cast-iron in black lead is helpful for lubricating the oil that reach store, wearability is so good. Same, the steel of excel of disappear shake sex of the existence as a result of black lead. Rehabilitate of cast of numerical control planer-type milling machine introduces: Craft of traditional gush solder, arc welding, after solder fills easy generation crackle, workpiece easy be heated is out of shape, appear easily 2 times stomatic, color of metal of solder filling place and difference of mother capable person are its common characteristic greatly, this also is the prime cause that traditional solder filling craft cannot solve rehabilitate of blemish of machine tool cast thoroughly. But, cast production to also be put in certain inadequacy, for example sand mold casts production working procedure is more, some craft are controlled hard, cast quality is not stable, blame frequency is taller; Cast organization is bulky often appear the blemish such as shrinkage cavity, loose, stoma, its are mechanical function is inferior to congener material forging; Cast surface is rougher, dimension precision is not tall; Labor strength of the worker is great, work requirement difference. Of cast of numerical control planer-type milling machine cast a method commonly used is colophony arenaceous, disappear the model is cast, it is special type casts a method next, be like: Metal mold is cast, fusible pattern is cast, gesso cast etc. And sand mold is cast can divide again for clay sand mold, organic binder sand mold, colophony from hard sand mold, disappear the model is waited a moment. Cast of numerical control planer-type milling machine casts the principle that the method chooses: Machine tool cast is preferential use sand mold to cast, main reason is sand mold is cast cast methodological cost than other technology of low, production cycle of simple, production is short. When wet model cannot consider to use clay arenaceous watch to do sand mold of sand mold, dry sand mold or other again when contented requirement. The cast weight that clay wet molding sand casts but from a few kilograms until a few kilograms, and the cast of clay doing production can heft a few tons. Machine tool cast casts a method to should suit with production lot photograph, low Die Casting is built, Die Casting, centrifugal casting cast a method, cast of numerical control planer-type milling machine because the price of equipment and mould is high, suit batch production only so, machine tool cast is OK odd cast also but batch production.
