Introduction to machine bed castings:
The machine bed is the basic part of the machine tool. It is required that the machine bed should have sufficient high static stiffness precision retention. Under the premise of meeting the overall design requirements, the structural design should be as reasonable as possible, and the ribs should be properly arranged. It is necessary to maintain the good hot and cold processing performance of the machine bed.
The relationship between the hardness of the machine bed and the tensile strength: there is a certain correspondence between the hardness and tensile strength of the gray cast iron. The empirical relationship is:
1. When O≥196N/mmm2 HB=RH (fly 00+0 4380b) (B1)
2. When 0≥796N/mmm2 HB=RH (44+O 7240b) (B2)
