Heat treatment process for forging machine tool bed body

Machine tool bed casting products, as a large type of casting, require heat treatment to improve their performance, and the inherent quality of cast iron platforms and bed castings. Cast iron flat plates are widely used in industries such as mechanical manufacturing, chemical engineering, hardware, aerospace, petroleum, automotive manufacturing, and instrument manufacturing.

When tempering machine tool bed castings, the tempering process should be strictly followed. Supporting ribs should be added to densely packed or easily deformed parts of the rib plate to prevent deformation and fracture caused by tempering temperature. There should be a dedicated person to monitor the tempering furnace thermometer, control the temperature in a timely manner, and prevent the temperature from being too high or too low, which will have a significant impact on the tempering workpiece. Cast iron flat plate: mainly used as a benchmark for inspecting workpiece errors, the inspection plate/inspection platform plays a crucial role in the mechanical manufacturing process. It is the basic benchmark tool for inspecting each workpiece before leaving the factory. Metal heat treatment is an important process in mechanical manufacturing. Compared with other processing techniques, heat treatment generally does not change the shape and overall chemical composition of the workpiece. Instead, it imparts performance to the workpiece by altering its internal microstructure or changing the chemical composition of the cast iron plate and machine bed surface. Cast iron flat plate: mainly used as a benchmark for inspecting workpiece errors, the inspection plate/inspection platform plays a crucial role in the mechanical manufacturing process. It is the basic benchmark tool for inspecting each workpiece before leaving the factory. Its characteristics are the inherent quality of cast iron flat plates and machine tool bed bodies.

Integrated heat treatment is a metal heat treatment process that heats the cast iron platform or machine bed as a whole, and then cools it at an appropriate speed to change the overall mechanical properties of the cast iron platform or machine bed. The overall heat treatment of cast iron platforms and machine tool bed bodies generally includes four basic processes: annealing, normalizing, quenching, and tempering. When casting and tempering cast iron platforms and machine tool bed bodies, the tempering process should be strictly followed. Supporting ribs should be added to densely packed or easily deformed parts of the cast iron platform ribs to prevent deformation and fracture caused by tempering temperature. There should be a dedicated person to monitor the tempering furnace thermometer, control the temperature in a timely manner, and prevent the temperature from being too high or too low, which will have a significant impact on the tempering workpiece.

To make the cast iron platform and machine bed body; The required mechanical, physical, and chemical properties (parameters of chemical reactions), in addition to the rational selection of materials and various forming processes, are determined by the heat treatment process. Steel is a widely used material in the mechanical industry, with a complex microstructure that can be controlled through heat treatment. Therefore, heat treatment of steel is the main content of metal heat treatment websites. In addition, aluminum, copper, magnesium, titanium and their alloys can also change their mechanical, physical and chemical properties through heat treatment to obtain different performance characteristics.
