A Quick Guide to Diamond Grinding Wheels
Diamond grinding wheels have many classifications. Their shape, bond, grit size, and concentrations determine their classifications. The application of these different types of grinding wheels are for different abrasive and grinding machining operations. Grinding machines greatly use the diamond grinding wheels in specific applications. If you are doing grinding or machining processes, it is important to use the proper grinding wheel.
There are many grinding and machining operations 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. 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. 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. These are the wheels used for plastic.
Knowing the types and applications of grinding wheels is important since each of these wheels are only used in specific applications. If you don’t use the proper type of grinding wheels, then your grinding operations will not be effective. 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.
Many types of materials and processes require a diamond grinding wheel. You only use diamond wheels strictly on carbides and a CBN grinding wheel is used on steel.
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. If you are going to use the hardest one, then you need to use the synthetic diamond wheel but if you need a soft one, then the alumina-zirconia is ideal. 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. If you are doing to remove metal from a non-ferrous material, then the appropriate wheel to use is the synthetic diamond blade. Use the alumina-zirconia wheel to grind soft metals.
You should next look at the nomenclature plate on the grinding machine. The speed rating in meters per second is the seed that ensures that you 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.
