Machine tool casting

Introduction to machine tool castings:

First, the machine bed standard: GB9439-88

Second, the characteristics of the bed:

Because gray cast iron has a high carbon content and is close to the eutectic composition, the melting point is relatively low, the fluidity is good, and the shrinkage rate is small, so it is suitable for casting complex or thin-walled castings. In addition, since graphite is easy to form chip breaking during cutting, the machinability of gray cast iron is superior to that of steel.

Third, the advantages of using resin sand casting machine tool bed castings

1 Resin sand type has good rigidity and high sand strength at the initial stage of casting. It has the condition to utilize the graphitization expansion of the solidification process of cast iron, effectively eliminate the shrinkage and shrinkage defects, and realize the less riser and no riser casting of gray cast iron and ductile iron castings. .

2 In the real casting production, the polystyrene foam molding is used to apply the furose resin self-hardening sand molding. When the molten metal is poured into the mold, the foam plastic form is rapidly vaporized under the action of the high-temperature molten metal, and burns and disappears. The molten metal replaces the position occupied by the original foam, and is solidified into a solid casting having the same shape as the shape.

3 Relatively speaking, lost foam casting has great advantages for producing single-piece or small-volume automobile covers, large-sized molds such as machine bed, and traditional sand molds. It not only saves expensive wood type costs, but also is easy to operate. It shortens the production cycle, improves production efficiency, and has the advantages of high dimensional accuracy, small machining allowance and good surface quality.
