The features of cast iron machine tool castings：

 

1. The cast iron platform will be deformed due to temperature changes. The cast iron platform should be used in a constant temperature environment.

 

2. Collision, smashing, beating, etc. may cause deformation of the cast iron platform, and placing an overweight workpiece on the platform will squeeze the cast iron platform.

 

3. The cast iron platform should be cast iron platform with the strength of HT200-300, the hardness of the working surface is HB170-240, and the cast iron platform with more than two aging treatments. Such cast iron platform has stable properties and good wear resistance.

 

The advantages of using resin sand casting machine bed castings:

 

1. The resin sand mold has good rigidity and high sand mold strength at the initial stage of pouring. This makes it possible to use the graphitization expansion of the cast iron solidification process to eliminate shrinkage and shrinkage defects, and realize the low riser and no riser casting of gray cast iron and ductile iron.

 

2. In the production of solid casting, the polystyrene foam pattern is used to form the furo resin self-hardening sand. When the molten metal is poured into the mold, the foamed plastic pattern quickly vaporizes under the action of the high-temperature molten metal, burns and disappears. The molten metal replaces the original foamed plastic position, and cools and solidifies into a solid casting with the same shape as the pattern.

 

3. Relatively speaking, lost foam casting has great advantages over traditional sand molds for the production of single or small batches of automobile panels, machine bed, large machine tool castings, cast iron pulleys and other large molds. It not only saves expensive The cost of the wood type is easy to operate, which shortens the production cycle and improves the production efficiency. It has the advantages of high dimensional accuracy, small machining allowance, and good surface quality.
