Machine tool castings improve performance through heat treatment

Heat treatment is a process to improve the performance of the casting itself and to improve the intrinsic quality of the cast iron plate. In the manufacturing process of the machine bed casting, heat treatment must be performed. This is mainly because the bed type casting product must be used as a large casting. After heat treatment can improve its own performance, improve the intrinsic quality of cast iron plate.

Metal heat treatment is one of the important processes in mechanical manufacturing. Compared with other processing technologies, heat treatment generally does not change the shape of the workpiece and the overall chemical composition, but by changing the microstructure within the workpiece, or changing the chemical composition of the workpiece surface , Give or improve the performance of the workpiece. Its characteristic is to improve the inherent quality of the workpiece.

In order to make the metal workpieces have the required mechanical properties, physical properties and chemical properties, in addition to the rational selection of materials and various forming processes, the heat treatment process is often indispensable. Steel is the most widely used material in the machinery industry. The microstructure of steel is complex and can be controlled by heat treatment. Therefore, the heat treatment of steel is the main content of metal heat treatment. In addition, aluminum, copper, magnesium, titanium, and their alloys can also be changed by heat treatment of their mechanical, physical and chemical properties to obtain different performance.

The bed casting is the base of the machine tool, which means that the heat-treated machine tool bed casting has better performance, making it fully play its fundamental role in the work.
