Versatile machine bed can be used for instruments, electronics, light industry, standard parts, bearing industry, the auto parts industry and other parts of the process, especially for non-ferrous metals. 
 Machine bed according to GB9439-88 standards for manufacturing, with good wear resistance, shock resistance and good consumer features. Graphite cast iron in favor of the lubrication and oil storage, so make good the wear resistance of machine bed. Similarly, the presence of graphite and gray cast iron consumption shock is better than steel. 
 Process performance machine bed is also very good, due to the high carbon gray cast iron, close to the eutectic composition, it is a relatively low melting point, good fluidity, shrinkage is small, so is suitable for complex or thin-walled castings foundry.
