Casting Iron Bed

Process Analysis

The product is a gray cast iron bed, and the machine tool bed castings are usually made of gray cast iron, and the graphite composition in it makes it have good lubricity and oil storage, thereby improving the wear resistance. At the same time, the presence of graphite also makes the shock absorption of gray cast iron better than that of steel. Excellent process performance: gray cast iron has a high carbon content and is close to eutectic composition, so it has a low melting point, good fluidity and small shrinkage. These properties make grey cast iron ideal for casting complex or thin-walled bed castings. Cost-effective: Sand casting is preferred for machine bed casting, because sand casting is lower cost, simpler production process and shorter production cycle than other casting methods. High precision and high quality. High precision and high quality: When using the resin sand casting machine tool bed casting, the stiffness of the resin sand mold is good, and the sand mold strength is high at the initial stage of pouring, which provides conditions for the graphitization expansion in the solidification process of cast iron, and effectively eliminates the shrinkage porosity and shrinkage defects.
