And can ensure the long-term stability and high precision of the machine tool.
Note: Meebake castings casting process control with its application
Meehanite Metal Casting: Meehanite Metal Casting undergoes a series of strict casting process control, such as the control of graphite carbon (GC) and combined carbon (CC) content in the iron material, the control of the metallurgical quality of the molten iron, i.e., the cleanliness and the control of the degree of subcooling (Under Cooling degree). After CA-SI inoculation, and then do the wedge value (Wedge Value) of the control; do 5 elements, alloying elements and nitrogen (N) content control, etc., in the casting is very easy to obtain the expected Polaroid iron base and graphite distribution, and enhance the mechanical properties.
In order to prevent deformation after processing, the castings are thoroughly annealed, which is conducive to the elimination of internal stress.
Application of GC40(GC275)
Dense baking GC40 type is most suitable for casting homogeneous castings with a thickness of 10-15mm. This type of material has dense organization, good strength, proper hardness, low friction coefficient and self-lubrication, so after surface quenching treatment, it is widely used in workpieces where the friction of metal surfaces with each other causes thermal shock, such as the body of the tool machine, the headstock, the table and the cylinder liner, etc. It has a wide range of applications.
