The principle of diamond grinding wheel laser trimming method

Laser trimming method is the use of an optical system for focusing the laser beam to a small spot in the diamond abrasive grinding wheel surface, only a small portion of the laser light is reflected, the majority of the laser is absorbed by the metal binder, the temperature rapidly rises, leading to being irradiated with a laser beam region, the metal binder is vaporized and removed, to remove binder material generally through: irradiation, absorption, heating, gasification several processes. When laser repair wheel, and reasonable control of the laser power density, can remove the surface of the diamond abrasive grinding wheel and a binder material, to achieve the purpose of shaping the wheel, by adjusting the laser processing parameters, also may be selectively removed diamond grinding wheel surface binding agent material, the diamond abrasive grains having a certain projection height and reach diamond grinding wheel dressing purposes. 4.2 Advantages of laser trimming method of laser trimming method is a non-contact method of trimming, trimming neither mechanical force, no trim loss tools, laser action a short time, a small diamond grinding cup wheel in the area of diamond grains and binder are not damage, ensure grain grinding performance, and high efficiency trimming, the disadvantage is trimming process more complicated and costly.
