Many people make the mistake of buying diamond grinding tools without even considering if it is suitable for the job at hand. Such an error can be costly as using the wrong diamond wheel can lead to premature breakage, and these things do not exactly come cheap.
Inning categorises diamond wheels by form, concentration, bond, and grit size. These wheels are used in many grinding and abrasive machining operations. As a result, diamond grinding wheels are used in grinding makers. In any machining or grinding procedure, it is always essential to use the appropriate grinding wheel.
Among the most commonly utilised grinding wheels today is the diamond and CBN wheels. These were available in several types consisting of resin, vitrified, metal, and electro-plated. The most typical amongst these types is the resin wheels. These are utilised in the most tool room and production applications. On the other hand, the vitrified and metal types are newer bond types and are used in particular applications. These are unusual and are more expensive. Additionally, these usually are custom made order products. However, electro-plated wheels are generally found in cut-off wheels and low requiring abrasive grinding such as that for plastics.
Why is it essential to use the right diamond grinding wheel?
It is crucial to know the various types of diamond grinding wheels and their applications because each of these types is mainly utilised on particular applications only. Furthermore, if you are not using the suitable wheel type, grinding operations may not be done efficiently. Therefore, before starting any grinding operations, it is essential to determine the kind of product to be worked on, and the grinding wheel too.
Diamond and CBN grinding wheels are used in a variety of processes and materials. Nevertheless, diamond wheels are utilised strictly on carbides while CBN is used on steels. In many cases though, some producers make grit that can be used on both carbides and steels.
The three kinds of diamond grinding wheels that are readily available in the market are artificial diamond, cubic boron nitride(CBN), and alumina-zirconia. Among these three types, the synthetic diamond is the hardest, while alumina-zirconia is the softest. In choosing the particular kind of wheel, there are some crucial factors to consider.
Primarily, it is essential to identify the firmness of the object you will be grinding. You must always bear in mind that CBN is most suggested for iron or steel. If the metal is non-ferrous though, and a significant amount of metal need to be gotten rid of, a synthetic diamond blade is the most suitable wheel to use. For soft metals, alumina-zirconia ought to be utilised.
Here are a couple of other things that you would do well to consider:
Look at the nomenclature plate on the grinding apparatus. The speed rating in meters per second is critical in guaranteeing that the bond of the diamond grit will not separate or break down when utilised on the grinding device.
Identify if the grinding will be done damp or dry. A wet diamond grinding wheel is utilised for precision cutting while a dry diamond grinding wheel is used for moderate grinding purposes.
Pick the coarseness of the wheel inning accordance with the quantity of metal that will be eliminated. Coarse grit is most proper for fast cutting while great gravel is utilised for a finish quality cut.
Last but not least, no matter what type of grinding tool you use, make sure that you take the necessary precautions and use the essential safety equipment. One such apparatus includes a concrete dust vacuum extractor which keeps you from inhaling dust particles that might cause a wide range of health problems.
