Technical Classification Of Grinding Wheel

Sep 05, 2017

     A circular bonded abrasive tool with a through hole in the center made of abrasive and binder. Grinding Wheel is the most use of abrasive, the most widely used surface of a high-speed rotation, suitable for processing a variety of metal and non-metallic materials. There are a wide variety of grinding wheels, different grinding wheels can be used for the workpiece's outer circle, inner circle, plane and various types of rough grinding, grinding and grinding, as well as cutting and slotting. According to a variety of shapes, sizes, abrasives, granularity, hardness, tissue and binder, such as different combinations, grinding wheel variety specifications up to 200,000 or so.Grinding wheel

    The size range of the grinding wheel is very large, such as the plating metal binder superhard abrasive wheel used for grinding the inner hole and the teeth of the parts, the minimum od is 0.5 mm; ceramic binder for large crankshaft grinding general abrasive wheel, the maximum diameter is 2000 mm ; a diamond ultrathin grinding wheel for cutting and grooving for semiconductor materials such as silicon wafers, the thinnest of which is 0.03 mm; the ceramic binder wheel for centerless grinding, the overall thickness of which is up to 600 mm.Grinding wheel

    The classification grinding wheel is divided into common abrasive (corundum and silicon carbide) grinding wheel and Superhard abrasive (diamond and cubic boron nitride) grinding wheel according to the abrasive materials used. The characteristics of ordinary abrasive grinding wheel are shape, diameter, thickness, diameter, abrasive, particle size, hardness, binder and tissue. The characteristics of Superhard abrasive grinding wheel are not labeled "tissue", but the amount of abrasive content is expressed in concentration.Grinding wheel

    Common abrasive grinding wheel commonly used in the shape of the wheel has more than 20 species (fig. 1 General abrasive wheel cross-section shape). In addition to abrasive, the main function of the grinding wheel is the binder, which affects the hardness, strength and grinding performance of the wheel, commonly used ceramic binder, resin binder and rubber binder. The corresponding grinding wheel is ceramic grinding wheel, resin wheel and rubber grinding wheel.Grinding wheel
