What are the main technologies for machining machine tool castings
Characteristics: By utilizing the good rigidity of resin sand molds, the strength of the sand mold is maintained during the initial pouring stage. Through the graphitization expansion during the solidification process of cast iron, shrinkage and porosity defects are effectively eliminated, achieving less riser and no riser casting of gray cast iron and ductile iron parts.
Application fields of machine tool castings
Core components: bed frame, columns, crossbeams, and other supporting structures that determine the rigidity of the machine tool.
