High-precision numerical control surface grinding machine convenient to move

The utility model discloses a convenient-to-move high-precision numerical control surface grinding machine which comprises a machine base, a plurality of supporting devices are symmetrically arrangedon the side wall of the machine base, sliding cavities are symmetrically formed in the machine base, a motor groove is formed in the upper side wall of each sliding cavity, and a motor is fixedly connected to the inner wall of each motor groove. The utility model is advantageous in that the structure is simple, when the numerical control surface grinding machine needs to be moved; the motor is started to drive the worm to rotate through the output shaft; therefore, the worm wheel is driven to rotate, therefore, the threaded rod is driven to rotate, therefore, the threaded pipe is driven to slowly move downwards; therefore, the walking wheels are in slow contact with the ground; until the walking wheels lift the supporting plate away from the ground; the numerical control surface grinder isflexible and convenient t
