In all of the applications outlined above, where a high precision engineering components are required, it is important to recognize the difficulties of machining Silicon Carbide. Despite the high hardness values it displays, it is nevertheless a relatively brittle material and can only be machined using diamond grinding techniques.

For this purpose, operator has to master up the special technique as carbide grinding is a slow process and attempts to speed it up by crowding the cut will usually result in cracked tips. For grinding cemented carbides, silicon-carbide wheels (the so-called green-grit wheels) are used, followed by diamond-impregnated wheels for finish grinding ...

Generally, wheels with 150 grit, 75 concentration, and R hardness are used for regular grinding. Finer grit wheels will give better finishes on the carbide and improve the cut quality, lengthen life between sharpening, and require less power than saws with rough grinds. These wheels, however, grind slower and require more time to finish a saw.

tomatic grinding, which could be important when the cross section at a specific depth is of interest. Automatic equipment is much more expensive than manual machines. Diamond abrasives are recommended for grinding most ceramics, but silicon carbide (SiC) paper and cubic boron nitride (CBN) platens can also be used.

The greater the cobalt content in the carbide, the greater the diamond wheel wear will be. In other words, the softer grades of carbide cause greater diamond wheel wear. One very important consideration is the concentration of diamond in the wheel. There is no doubt that an increase of diamond up to 125% greatly improves the grinding performance.

The grinding wheel does not cut as freely, thereby producing more heat in the grind zone. More important, the profile of the grinding wheel wears so that the geometry and precision of the workpiece suffers.
