The nature of the introduction and application of Concrete cutting wheels

  Concrete cutting wheels in a wide range of different wheels can cylindrical, inner circle, plane and a variety of type faces and other parts of coarse grinding, semi-fine grinding and grinding, as well as concrete cutting wheels and slotting, respectively. Central wheel with abrasive and made ​​binding agents have rounded abrasive vias. Many types of grinding wheels, different wheel can cylindrical, inner circle, plane and a variety of type faces and other parts of coarse grinding, fine grinding and cutting wheels   half, as well as concrete cutting wheels and slotting, respectively. Conventional abrasive concrete cutting wheels characteristic has the shape, diameter, thickness, diameter milk, abrasive, grain size, hardness, binders and organizations. Resistance when turning the wheel rupture under the centrifugal force. Since the tensile strength is lower than the compressive grinding or flexural strength, tensile strength usually measured wheel, the size is mainly determined by the performance and the amount of binding agent, the green density and firing temperature. When the wheel speed rotation and due to the tangential Cut off wheels  along the aperture itself produced the critical time to reach the tensile strength, the wheel will break, when the wheel rotation speed is called the rupture rate. The actual axis of rotation of the grinding wheel parallel to its axis of rotation through the center of mass offset from a state known as static unbalance wheel. This is usually due to the grinding wheel uneven density, both ends of the plane is not parallel or cylindrical hole concentricity deviation has caused. It will cause the machine vibration, shaft and bearing wear faster, uneven wheel wear and deterioration of the workpiece surface quality. Concrete cutting wheels is the largest amount, the most widely used method of using face when using high-speed rotation, suitable for processing a variety of metal and non-metallic materials.
