A Quick Guide to Diamond Grinding Wheels
Diamond grinding wheels have many classifications. You can classify these wheels according to their shape, bond, grit, size, and concentrations. 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.
The diamond wheels are widely used in grinding wheels today. There are many types of diamond wheels including resin, metal, vitrified, and electro-plated. The resin wheels are the most common of these wheels. In many tool room and production applications the resin wheel is used. There are more specific applications for the metal and vitrified types of wheels and they are newer bond types. It is quite expensive to buy these kinds of wheels because they are quite rare. You don’t usually see these types of wheels in the market but your need to have the custom made-to-order. You find electro-plated wheels in cut-off wheels and they are used in low demanding abrasive grinding. 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. 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.
Diamond grinding wheels are used in many types of materials and in many different processes. 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. You need to consider some factors when selecting a particular type of wheel.
You should first find out how hard the material that you will grind is. 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 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.
The last steps include determining whether you will do wet or dry grinding, and selecting the coarseness of the wheel. You then need to choose the right grinding wheel to use for these applications.
