Introduction:Heavy duty machine tool castings have good wear resistance and shock absorption Due to the favorable lubrication and oil storage properties of graphite in cast iron, heavy-duty machine tool castings have good wear resistance Meanwhile, due to the presence of graphite, the shock absorption of machine tool castings is superior to that of steel

Heavy duty machine tool castings standard: GB9439—88, Heavy duty machine tool castings are made of resin sand and lost foam solid casting, with a single piece weighing up to 80 tons

Heavy duty machine tool castings have good processability. Due to its manufacture of gray cast iron, which has a high carbon content and is close to eutectic composition, its melting point is relatively low, its flowability is good, and its shrinkage rate is small. Therefore, it is suitable for casting complex or thin-walled castings. Similarly, due to the tendency of graphite to form chips during cutting, the machinability of gray cast iron is superior to that of steel.
Heavy duty machine tool castings have good wear resistance and shock absorption. Due to the favorable lubrication and oil storage properties of graphite in cast iron, heavy-duty machine tool castings have good wear resistance. Meanwhile, due to the presence of graphite, the shock absorption of large bed castings is superior to that of steel.
The quality control of heavy-duty machine tool castings first lies in stabilizing the production process, avoiding the occurrence of systematic errors and the accumulation of random errors. Secondly, it is necessary to improve the precision of the manufacturing process and reduce the frequency distribution range or dispersion degree of errors.
Due to the special manufacturing process of heavy-duty machine tool castings, the surface of large machine tool castings is prone to rust, and it is difficult to treat after rust. If not taken seriously, not only will the anti rust ability of the workpiece be poor, but the decorative quality will also be poor. Many enterprises, while demanding high corrosion resistance for heavy machine tool castings, require room temperature blackening, phosphating treatment, and other special rust prevention treatments for heavy machine tool castings according to the different working conditions of large machine tool castings. The surface rust prevention treatment of heavy machine tool castings is increasingly receiving attention.
Machine tool castings include machine tool bed, worktable, column, crossbeam, and gantry top connecting beam. Heavy duty machine tool castings have good wear resistance and shock absorption. The melting point is relatively low, the fluidity is good, and the shrinkage rate is small.
