As the large castins, lathe bed castingsmust be subjected to heat treatment in order to improve the performance itself,and  improve the intrinsic quality ofiron castings. Usually the heat treatment does not change the overall shape andchemical composition of the workpiece, but by changing the microstructurewithin the workpiece, or to alter the chemical composition of the workpiecesurface to improve the performance of the work piece. Its characteristic is toimprove the intrinsic quality of the workpiece.
