What kind of material is used for the spindle of precision machine tools?

The spindle of a precision machine tool (such as a grinding wheel shaft and a coordinate boring spindle) can be made of 38CrMoAIA nitrided steel. After quenching and tempering and surface nitriding, the steel not only achieves high surface hardness, but also maintains a soft core and thus has good impact toughness. Compared with carburized and quenched steel, it has the characteristics of small heat treatment deformation and higher hardness.
