The quality of machine tool castings includes appearance quality and internal quality (usually refers to the casting material) and design quality (refers to the quality of use); and the appearance quality refers to the surface roughness, surface defects, dimensional deviation, shape deviation, and weight deviation of the machine tool casting.

Appearance quality of machine bed castings

Appearance quality refers to the surface roughness, surface defects, size deviation, shape deviation, and weight deviation of machine tool castings; internal quality mainly refers to the chemical composition, physical properties, mechanical properties, metallographic structure of machine tool castings, and the holes, cracks, and cracks that exist in the castings. Inclusions, segregation, etc.; the quality of use refers to the ability of machine tool castings to work under different conditions, including corrosion, chilling and heat resistance, fatigue, shock absorption and other properties, as well as machinability, weldability and other process properties.

The casting quality of the machine tool has a great influence on the performance of the mechanical product. For example, machine tool castings and dimensional stability directly affect the accuracy of machine life maintenance.

Internal quality of machine tool castings

When designing, in addition to determining the geometry and size of the machine tool castings according to the working conditions and metal material properties, the rationality of the design is also considered from the perspective of the casting alloy and casting process characteristics, that is, the obvious size effect and solidification and shrinkage , Stress and other problems to avoid or reduce the occurrence of defects such as component segregation, deformation, and cracking of copper castings.
