There are many ways to classify diamond grinding 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. There is a need to use the proper grinding wheel in any grinding and machining processes.
There are many applications today that use the diamond grinding wheels. They can be found in many different types which include resin, metal, vitrified, and electro-plated. Resin wheels are the most used among these types of grinding wheels. Resin wheels are used in many tool room and production applications. The newer bond types are the metal and vitrified types of wheels which can only be used in specific applications. It is quite expensive to buy these kinds of wheels because they are quite rare. They are custom made-to-order types of wheels. Electro-plated wheels are usually found in cut-off wheels and 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. The effectiveness of the grinding wheels can only be achieved if you use the proper type of grinding wheels; otherwise, this will not be achieved. 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.
You should first find out how hard the material that you will grind is. CBN should be used for iron or steel. For non-ferrous metal where you need to remove a large amount of metal, the synthetic diamond blade should be used. If you are grinding soft metals, then the wheel to use is the alumina-zirconia.
You should next look at the nomenclature plate on the grinding machine. Check the speed rating in meters per second because this ensures that the bond of the diamond grit will not disintegrate or separate when used on the grinding machine.
Finally, determine if the grinding is wet or dry and determine the wheel’s coarseness. You then need to choose the right grinding wheel to use for these applications.
