Blank for shaft parts

May 30, 2019

The blanks of shaft parts are commonly found in profiles (round bars) and forgings. Large, contoured shafts can also be cast. The crankshafts in internal combustion engines are generally made of casting blanks. The profile blanks are divided into hot-rolled or cold-drawn bars, which are suitable for stepped shafts with smooth shafts or small diameters. After the forging blank is heated and forged, the internal fiber structure of the metal is distributed along the surface, so that it has high tensile, bending and torsional strength, and is generally used for important shafts.
