1. The machine bed, column, headstock and other key parts are made of Mihanna (closely baked) castings, with stable organization and permanent quality. The casting has been calculated and analyzed by finite element analysis computer. The reasonable structural strength and the matching of reinforcing ribs provide high rigidity of the machine. The casting material grade is GC-275. The casting structure adopts the integrated molding technology, and the box structure. Our company's large pentahedron processing machine is used for processing, which is completed in one clamping process. The machine tool has high rigidity, high strength, and excellent geometric positioning accuracy. And it can ensure the long-term stability and high precision of the machine tool.
Note: The control of the casting process for dense baked castings is based on its application
Process control of closely baked metal casting: closely baked metal casting goes through a series of strict process control, such as the control of graphite carbon (GC) and bonded carbon (CC) content in iron; Control of molten iron metallurgical quality, i.e. cleanliness and undercooling degree; After inoculation with CA-SI, the wedge value is controlled; Control the content of 5 elements, alloy elements and nitrogen (N), etc., and it is very easy to obtain the expected wave iron base and graphite distribution after casting, so as to improve the mechanical properties.
In order to prevent deformation after processing, the castings are thoroughly annealed to eliminate internal stress.
Application of close baking GC40 (GC275)
Compact baking GC40 is most suitable for casting homogeneous castings with a thickness of 10-15mm. This type of material has dense structure, good strength, proper hardness, low friction coefficient, and self lubrication. Therefore, after surface quenching, it is widely used on workpieces with thermal shock caused by mutual friction between metal surfaces, such as tool body, head seat, table top, cylinder sleeve, etc.
