Although tungsten carbide is commonly used to make tool tips, especially cutting tools, it also needs to be ground because it must meet certain specifications in order to give the necessary shape and finish to the workpiece it is used in. This process can only be done with abrasive methods, and the suitable abrasive to work effectively is a diamond-based abrasive, depending on its hardness. Diamond-based abrasives come in the form of hard abrasives (wheels or coated tools), but also in the form of sheets, rolls, belts or discs on flexible supports, and can even be used manually or with portable machinery.
These processes can generate very high temperatures due to the friction between the workpiece and the grinding material, so it is recommended to carry out this kind of grinding, paying special attention to its grinding thermal effect, which can be achieved by adding coolant or properly adjusting the cutting and feeding speed and exposure time. , to prevent the material from getting too high a temperature that could damage it. As for the size of the grit, it will depend on the amount of material that needs to be extracted and the necessary finish. In major roughing processes, such as honing cylinders to remove and repair coatings, coarse grit (357µm/P40 or 251µm/P60) can be used. If polished or low roughness is required, fine grain (46µm/P320 or 30µm/P500) can be used, giving a Ra roughness of around 0.1µm depending on the process. For critical surface preparation processes where particularly low roughness is required, flexible abrasives with a polyester film support are also available, with grit sizes up to 0.5µ/>P5000.
Technological advances in binders and flexible supports over the past few decades have made flexible diamond abrasives a more effective and economical tool in many applications for grinding Tungsten Carbide Components because they are less expensive to manufacture and the size of the abrasive grain Orientation, in a single layer, is more efficient in the cutting process, increasing roughing rates and significantly reducing operating temperatures. As an abrasive manufacturing expert, we have rich experience in the production of Tungsten Carbide Dies And Molds, Tungsten Carbide Bushing, Tungsten Carbide Punch And Pin.
