Applications of Diamond Grinding Wheels
Diamond grinding wheels have many classifications. You can classify these wheels according to their shape, bond, grit, size, and concentrations. These different types are wheels are used in many different abrasive and grinding machining operations. Grinding machines greatly use the diamond grinding wheels in specific applications. 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. There are many types of diamond wheels including resin, metal, vitrified, and electro-plated. The resin wheels are the most common of these wheels. Resin wheels are used in many tool room and production applications. The metal and vitrified types of wheels are newer bond types and they are used in more specific applications. They are more expensive since these are rare. You don’t usually see these types of wheels in the market but your need to have the custom made-to-order. For low demanding abrasive grinding you use electro-plated wheels which you find in cut-off wheels. A good example is that for plastics.
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. So, before starting your grinding operations, you should first determine the type of materials you are working on and the type of grinding wheel that you should use.
Many types of materials and processes require a diamond grinding wheel. Diamond wheels are used strictly on carbides but on steel a CBN grinding wheel is used.
There are three types of diamond grinding wheels that you can use today including 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. The factors given below should be considered when selecting the type of wheel to use.
First is the you should determine the hardness of the item that you will grind. If you are going to grind iron or steel, then the ideal wheel is a CBN wheel. 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.
You should next look at the nomenclature plate on the grinding machine. If you check the speed rating in meters per second, then you can determine if the speed is not something that will make the grit disintegrate or separate during operation.
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.
