Rigidity is the core performance indicator of machine tool castings including beds, columns, worktables and spindle boxes. When castings lack enough structural stiffness, a series of precision, processing and service fail...

Shrinkage cavities are hollow voids formed inside machine tool gray iron castings during solidification, mainly appearing at thick bosses, rib junctions, wall-thickness mutation areas and isolated heavy sections. They are...

Long-term service deformation of machine tool castings (bed, column, worktable cast iron castings) stems from latent internal casting stress, alternating workshop loads, thermal circulation, continuous vibration and struc...

Machine tool castings such as machine bases, columns and worktables are mostly made of gray cast iron. Subject to melting, molding, pouring and cooling processes, various internal and surface casting defects are easily fo...

Regular maintenance is essential to retain flatness accuracy,prevent rust,and extend the service life of cast iron inspection platforms.Routine maintenance can be divided into daily,weekly,monthly and annual standardized ...

Cast iron measuring tables can be temporarily placed in humid production workshops, but they are not suitable for long-term continuous use without complete anti-rust protection. High humidity brings multiple irreversible ...

Neither plate is universally inferior; the answer depends on the workshop’s working conditions, production demands and inspection accuracy standards. Each material carries distinct drawbacks that make it the poorer choi...

Flatness deviation of cast iron inspection plates is derived from casting inherent defects, workshop operating environments, improper usage and long-term aging. All factors will break the uniform datum plane and produce m...
