The green cutting disc is the type of cutting piece commonly used in the cutting piece market today, and it is also a kind of cutting piece which is more popular by users, but because it is relatively sharp, many novice users will use it because they do not pay attention to some matters. Some surprises, how can users avoid this happening? What should you pay attention to when using green cutting disc?
When the diameter of the cutting piece is less than 40 mm and the speed of the grinding wheel is less than 50 mm and the speed of the grinding wheel is below 34 m/s, the circumferential wall thickness of the protective cover is not less than 6 mm, and the thickness of the two side walls is not less than 4 mm. If a protective cover is made of cast steel, its wall thickness should be 12 times thicker than that of the steel plate. If the diameter or width of the grinding wheel is increased, the wall thickness of the protective cover should be correspondingly thickened. In high-speed grinding, the wall thickness of the protective four is increased, and the reinforcing plate is used to make the structure more firm; the energy layer can be returned to the inner wall of the protective cover to reduce the impact of the grinding wheel debris on the casing. Under the premise of not affecting the grinding of the grinding wheel, the opening of the casing should be reduced to reduce the chance of the grinding wheel breaking block flying out of the opening, and to reduce the scattering surface when the piece flies out.
In addition, when grinding and trimming the cutting piece, care should be taken to prevent the grinding and crushing of the sand and the splashing of the grinding fluid and the formation of water mist, so as not to affect the operator’s health and environmental pollution.
