Description
Technical Field
The utility model relates to a emery wheel field of making, concretely relates to metal grinding wheel.
Background
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.
While different grinding tools are provided for different grinding materials.
