Machine tool castings are indispensable basic parts in machine tool manufacturing. They are mainly made of cast iron (such as gray cast iron, etc.). Through the casting process, they exhibit good rigidity, shock absorption, wear resistance, and dimensional stability, which can meet the strict requirements of the machine tool for structural strength and accuracy. It includes key parts such as beds, columns, beams, workbenches, and spindle boxes. The structure of these parts is usually relatively complex. They need to be molded through sand casting, precision casting, and other processes, followed by aging treatment to eliminate internal stress to ensure that they do not easily deform during long-term use.
