The utility model provides a
grinding mechanism of a
numerical control grinding machine, which relates to the technical field of
numerical control grinding machines, and comprises a
workbench, a base, a mounting surface, a sliding table and a movable table, the sliding table and the base are in transmission through a
ball screw pair, the sliding table and the movable table are in transmission through a
ball screw pair, and a gear motor is arranged on the movable table. The output end of the gear motor is provided with a chuck, the chuck is connected with a driving module, the output end of the driving module is provided with a
grinding wheel, the driving module is provided with a
grinding wheel cover, and due to the fact that the installation face of the base in the grinding mechanism is obliquely arranged, the length of the sliding table can be increased, and then the
stroke of the movable table on the sliding table is increased; and under the condition that the moving
stroke of the
grinding wheel is increased, the parts, protruding out of the back side of the
workbench, of the sliding table and the movable table are obviously lower than the situation that the mounting face of the base is horizontally arranged, the space above the
workbench is reasonably utilized, the equipment is more compact, and the occupied area of the equipment is reduced.
