There are many classifications of diamond wheels. These include classifications according to their shape, bond, grit size, and concentrations. When you need to do abrasive and grinding machining operations, then these different types of grinding wheels are used. So, the usage of diamond grinding wheels are for grinding machines. If you are doing grinding or machining processes, it is important to use the proper grinding wheel.
There are many applications today that use the diamond grinding wheels. There are many types of diamond wheels including resin, metal, vitrified, and electro-plated. Resin wheels are the most used among these types of grinding wheels. In many tool room and production applications the resin wheel is used. The newer bond types are the metal and vitrified types of wheels which can only be used in specific applications. These wheels are quite rare so that makes them more expensive. They are custom made-to-order types of wheels. You find electro-plated wheels in cut-off wheels and they are used in low demanding abrasive grinding. These are the wheels used for plastic.
Because these types of wheels have their own specific applications, it is then important to know what these wheels are and in what applications they are used. Your grinding operations may not be done effectively if you don’t use the proper types of wheels. It is, therefore, very important to determine the type of materials you are working on and the appropriate grinding wheel that you should use for this before even starting your grinding operations.
There are many processes and materials where you use diamond grinding wheels. Diamond wheels are used strictly on carbides but on steel a CBN grinding wheel is used.
Other classifications of diamond grinding wheels include the synthetic diamond, the cubic boron nitride (CBN) and the alumina-zirconia. The synthetic diamond is the hardest of the three and the softest is the alumina-zirconia. If you are deciding on what appropriate wheel to use, then consider the factors given below.
The hardness of the item that you will grind should first be determined. For iron or steel, you should use CBN. A synthetic diamond wheel is ideal for non-ferrous materials where you need to remove a large amount of metal. Alumina-zirconia should be used for soft metals.
After deciding on the appropriate wheel to use, the next thing is to look at the nomenclature plate on the grinding machine. You need to check if the speed of the grinding machine will not let the wheel disintegrate or separate during operation and this can be determined by the speed rating in meters per second.
The last steps include determining whether you will do wet or dry grinding, and selecting the coarseness of the wheel. To get the best results, you need to determine the right grinding wheels for these conditions.
