[ background of the invention ]
The grinding wheel is a bonded grinding tool which is formed by bonding a common grinding material into a certain shape (mostly circular, with a through hole in the center) by a bonding agent and has certain strength. It is generally composed of abrasive, bond and air holes, which are often referred to as the three elements of a bonded abrasive tool. According to different classes of binders, ceramic (binder) grinding wheels, resin (binder) grinding wheels, and rubber (binder) grinding wheels are common. The grinding wheel is the one with the largest use amount and the widest use range in the grinding tool, rotates at high speed when in use, and can perform coarse grinding, semi-fine grinding, slotting, cutting and the like on the excircle, the inner circle, the plane, various molded surfaces and the like of a metal or nonmetal workpiece. Because the grinding wheels are made of various materials, and the grinding wheels with the same application have very large price difference after selecting components of different formulas, the cost difference between the high-quality grinding wheel and the poor-quality grinding wheel can reach several times to dozens of times. For convenience of manufacture, conventional grinding wheels are generally made of the same material for the whole grinding wheel, but when used, the grinding wheel is discarded when worn to a certain extent. If a good material is used at a part to be ground in the grinding wheel and a poor material or a metal core is used at a part which is left to be discarded after being worn, a large amount of cost can be saved, and the cost and the selling price of the product are reduced; the product with more cost performance is launched to the market on the basis of not losing the product quality, and the metal core also has recoverable value and responds to the call of environment protection and energy conservation advocated by the nation.
