Diamond Grinding Wheel can be termed to be a new product introduced among grinding wheels. Only after synthetic materials got discovered that it was manufactured! Research conducted into synthetic materials is credited to have resulted in producing synthetic diamonds including the discovery of CBN or cubic boron nitride. Synthetic diamonds are regarded as among the hardest materials discovered now. These are used mainly to manufacture grinding wheels.

Synthetic diamonds are said to have copper and nickel coating to ensure longevity. Diamond Grinding Wheel is created from synthetic diamonds. They are durable, hence, referred to as super abrasives.

Why Diamond Grinding Wheels are considered to be super-abrasives?

  • Structure

When the structure is concerned, these wheels can be found to come in different shapes like cones, cylinders, cups, flat disks, and wheels. Their profiles are cut within their periphery. Diamond is also stated to be CBN grinding wheels. Usually, they are classified by their grit size, shape, bond, and concentration. For Resin Grinding Wheel, the abrasive’s grit size is chosen depending on the cutting material’s hardness.

  • Grit size

Generally, grit is used in sizes ranging from 120 to 180. This is when the grinding wheel is created to be used in several tool room applications. Usually, finer grits of 220+ are created on special order. It is meant to be used in superior quality and fine surface finishes. The abrasive concentration depends mostly on what type of application the wheel needs to serve. You can get a basic idea from the leading Resin Grinding Wheel manufacturer.

Diamond concentration in grinding rim mainly depends upon the application. To enable hardened steel or tungsten carbide stock removal, there is selected a concentration of about 75-125. However, select 150 concentrations if the grinding wheel contact surface to the material is found to be small. The Diamond Grinding Wheel manufacturer can enumerate this aspect.

When manufacturing Diamond Grinding Wheel China, another aspect involved the bone. It is generally used for keeping together the abrasive grains. The grinding wheels used bonds that are refined for several years. Presently, the main bond options offered are vitrified bond, resin bond, and metal bond. They are then electroplated using resin. Metal and vitrified bonds generally cost much more and need to be custom ordered. Generally, electroplated wheels are used for cut-off wheels including low abrasive grinding such as plastics.

Generally, Diamond Grinding Wheel tends to have specific marking to assist identify them. For example, D1A1-150R 100-B4! Here, D1A1 means wheel shape, grit size is 150, concentration is 100, and manufacturer bond is B4.

  • Types

Manufacturers of Diamond and Resin Grinding Wheel China assign the hardiness extent of the wheel. It is achieved either by allowing the fracturing of abrasive grains or restricting fracture. As the wheel gets fractured by the abrasives easily, it is referred to as a soft bond. But hard bond wheels are designed to withstand much larger forces as fracturing gets restricted. Usually, soft wheels are used for Diamond Grinding Wheel surfaces to cut them easily. It also has a shorter life. But hard wheels are more durable and utilized in finer surface finishes.
