Grinding is a type of machining process that uses abrasive grains to remove material from the work piece. Abrasive grains are made into discs, wheels, or points mounted on a machine with a rotating motor. Together with the motor, the entire machine is called a grinding machine or grinder. The grinder can be a power tool or machine tool. A power grinder is operated by hand and portable. A machine grinder is a fixed structure with constraining mechanism that holds the work piece in place and guiding mechanism that moves the grinding discs, wheels, or points about. Grinders are used for various applications such as forming, sharpening, surface finishing, and deburring.
Between grinding discs, wheels, and points, the latter two are more similar to each other and makes use of actual grinding action in which material is grinded off from the work piece whereas grinding discs are primarily used for cutting apart work pieces.
The main difference between grinding wheels and grinding points is that grinding wheels are operated as machine tools while grinding points are operated with power tools.
Diamond is one of the hardest materials available. It can be grounded into tiny fragments that can be used as abrasives. Diamond grinding tools are excellent for working with raw materials that are too hard for traditional grinding tools.
Diamond grinding wheels and diamond grinding points provide faster processing. However, diamond is not an all-in-one solution for grinding. The tools cannot be used on steel and certain carbon-rich materials. Minerals on steel and steel alloys can react with the diamond particles. So does the carbon from the carbon-rich materials.
