Research on Manufacturing Process and Production Application of High Strength and Low Stress Cast Iron Parts
On the machine tool casting deformation,cracking and other failure problems,the foreign high-end CNC machine tool casting structure and material production control technology was studied,found that the main problem of machine tool failure in the casting structure strength is low and the material rigidity is poor,so that the casting stress becomes large,the machine tool deformation due to the casting stress release,precision loss.Through casting simulation analysis,reverse optimization of casting structure,pouring system,etc.,with high carbon equivalent+composite alloying melting process,combined with complex aging process,the casting of high strength and low stress castings is realized.
