The quality of machine tool special-shaped castings has a significant impact on the functionality of mechanical products. For example, the wear resistance and dimensional invariance of machine tool castings directly affect the accuracy and durability of the machine tool. The primary method we accept is to increase the temperature of the molten iron, establish a perfect blast furnace detection system, and ensure that the blast furnace is in a normal state.

The quality of machine tool special-shaped castings has a significant impact on the functionality of mechanical products. For example, the wear resistance and dimensional invariance of machine tool castings directly affect the accuracy and durability of the machine tool. The primary method we accept is to increase the temperature of the molten iron, establish a perfect blast furnace detection system, and ensure that the blast furnace is in a normal state. The selection of process parameters for special-shaped castings has a significant impact on the dimensional accuracy and wheel clarity of the castings.

The internationally popular heat treatment process for machine tool castings (bed frame castings) (large castings) minimizes stress and deformation of the castings. Long term use tends to be more stable.

Machine Tool Castings (Bed Castings) (Large Castings) Grey Iron Castings Standard: GB9439—88

Characteristics of machine tool castings (bed frame castings) (large castings):

Machine tool castings (bed frame castings) (large castings) have good wear resistance and shock absorption. Due to the favorable lubrication and oil storage properties of graphite in cast iron, it has good wear resistance. Similarly, due to the presence of graphite, the shock absorption of gray cast iron is superior to that of steel.

Machine tool castings (bed frame castings) (large castings) have good processability. Due to its high carbon content and eutectic composition, gray cast iron has a relatively low melting point, good flowability, and low shrinkage rate, making it suitable for casting complex or thin-walled castings. In addition, due to the tendency of graphite to form chips during cutting, the machinability of gray cast iron is superior to that of steel.

The relationship between the hardness and tensile strength of machine tool castings (bed frame castings) (large castings): There is a certain correspondence between the hardness and tensile strength of gray cast iron, and its empirical formula is:

a. When O ≥ 196N/mm ㎡

HB=RH (Fly 00+0 4380b) (B1)

b. When 0 ≥ 796N/mm ㎡

HB=RH (44+O 7240c) (B2)

The relative hardness (RH) value in the formula for machine tool castings (bed frame castings) (large castings) is mainly determined by the raw materials, melting process, processing technology, and cooling rate of the castings.

Machine tool castings (bed frame castings) (large castings) using resin sand moldsCasting machine toolAdvantages of bed frame castings

Machine tool castings (bed body castings) (large castings) have good rigidity in resin sand molds, and the initial strength of the sand mold is high during casting. This allows for the effective elimination of shrinkage and porosity defects by utilizing the graphitization expansion during the solidification process of cast iron, achieving less riser and no riser casting of gray cast iron and ductile iron parts.
