The utility model relates to a device for dressing a metal bond diamond grinding wheel by a short wavelength ultrafast laser, wherein a three-dimensional galvanometer scanning system is arranged on the output light path of the ultrafast laser, and the output end of the three-dimensional galvanometer scanning system is opposite to the grinding wheel on the clamp; Adopt ultrafast laser; The parameters of the laser are set to the scanning speed range of 0.5-2M/S and the scanning distance range of 0.01-0.02mm；; Put the grinding wheel on the fixture, adjust the position of the grinding wheel relative to the focal point of laser spot, scan the grinding wheel with laser beam, and carry out orthogonal tests from three laser process parameters: laser power, pulse repetition frequency and scanning times. After the test, observe the microscopic image of the grinding wheel surface under the laser focusing microscope, compare the sharpening effect of grinding wheels under different process parameters according to the size, protruding height and the number of abrasive grains per unit area of the grinding wheel surface, and determine the best process parameters. Avoid the thermal effect during grinding wheel dressing and improve the surface quality after dressing.
