Machine bed details

Machine bed analysis and annealing types: common annealing processes are: recrystallization annealing, stress relief annealing, spheroidizing annealing, complete annealing, etc. The purpose of annealing: mainly to reduce the hardness of metal materials, improve plasticity, to facilitate cutting or pressure processing, reduce residual stress, improve the homogenization of structure and composition, or prepare for the subsequent heat treatment.

Machine bed body features:

(1) Good wear resistance and shock absorption. Since graphite in cast iron is beneficial for lubrication and oil storage, the wear resistance is good. Similarly, due to the presence of graphite, grey cast iron is superior to steel in shock absorption.

(2) Good process performance. Because gray cast iron has a high carbon content and is close to the eutectic composition, the melting point is relatively low, the fluidity is good, and the shrinkage rate is small, so it is suitable for casting complex or thin-walled castings. In addition, since graphite is easy to form chip breaking during cutting, the machinability of gray cast iron is superior to that of steel.
