Shaft parts should use different materials and different heat treatment specifications (such as quenching, normalizing, hardening, etc.) in order to obtain a certain strength, toughness and wear resistance depending on the operating conditions and requirements. After quenching cheap price (or normalized) after precision shaft parts, 45 steel shaft parts are commonly used materials. Get better cutting performance automotive shafts, and can obtain high strength and toughness and other mechanical properties shaft parts, surface hardness after quenching up to 45 ~ 52HRC. ⑵ end of the inner cone taper spindle nose (Mohs 6) of the bearing journal A, B at the end of the shaft surface runout tolerance of 0.005mm at mechanical shaft parts, off-axis 300mm at the end surface tolerance of 0.01 mm; cone contact rate ≥70%; surface roughness Ra of 0.4mm; hardness 45 ~ 50HRC. The cone is used to install the top or tool taper, the axis must be supported by two journal axis coaxial strict, otherwise it would work (or tool) to produce concentricity error.
