2.Machine shaft – It is the shaft which is an integral part of the machine. 1.2 Manufacturing of shaft. Generally, shafts are manufactured by a hot rolling process which has low dimensional accuracy, finished by turning and grinding. The cold rolled shafts are stronger and accurate than hot rolled shafts but they have highly residual stresses.
