Research on rotation accuracy test of grinding wheel hybrid spindle in high accuracy grinder

The rotational accuracy of grinding wheel spindle system with hydrodynamic and hydrostatic bearing in a high accuracy grinding machine is tested, and the results show that the rotational accuracy of the spindle system is very high. The research results of rotational accuracy, static rigidity, vibration resistance and thermal stability of the spindle show that it is a very good grinding machine grinding wheel spindle.
