The internationally popular heat treatment process for machine tool castings (bed castings) (large castings) can reduce the stress deformation of castings to a minimum. It becomes more stable with long-term use.
Standards for gray iron castings for machine tool castings (bed castings) (large castings)
Characteristics of machine tool castings (bed castings) (large castings):
Wear resistance and shock absorption of machine tool castings good. Since the graphite in cast iron is beneficial to lubrication and oil storage, it has good wear resistance. Likewise, gray cast iron is better at absorbing shock than steel due to the presence of graphite.
Machine tool castings (bed castings) (large castings) have good process performance. Because gray cast iron has high carbon content and is close to the eutectic composition, it has a relatively low melting point, good fluidity, and small shrinkage, so it is suitable for casting complex structures or thin-walled castings. In addition, since graphite makes it easy to form chip breakers during cutting, the machinability of gray iron is better than that of steel.
The relative hardness () value of machine tool castings (bed castings) (large castings) in the formula is mainly determined by the raw materials, melting process, processing technology and the cooling rate of the casting.
