Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] See Figures 1 to 3 This utility model embodiment provides a vertical grinding machine, including:

[0028] Base 1, on which an X-axis drive mechanism 2 is provided;
