Silicon Carbide Machining & Grinding. Silicon Carbide can be machined in green, biscuit, or fully dense states. While in the green or biscuit form it can be machined relatively easily into complex geometries. However, the sintering process that is required to fully densify the material causes the Silicon Carbide body to shrink approximately 20%.

The grinding wheels with D25 grit size of diamond grains worked at a speed of 15m/s and depth of grinding 0.002 and 0.005 mm/double stroke. All the grinding performance parameters were comparable for both types of wheels. Better results were obtained by D25 grinding wheels with Ba23 bis binder.
In this study, the effect of sintering temperature on mechanical and wear behaviour of a new vitrified abrasive composite for grinding wheels is investigated and compared with a reference vitrified abrasive composite used in grinding tools for surface grinding, saw sharpening and internal grinding.
"Grinding Wheel Materials" provides a detailed overview of the various abrasive and bond materials used in grinding wheels. The properties of the abrasive grains and bond material are important factors in any grinding operation. Abrasives vary not only in type but also in size, hardness, and friability. Bond material can vary in porosity, strength, and amount.
A grinding wheel is a wheel composed of an abrasive compound and used for various grinding (abrasive cutting) and abrasive machining operations. Such wheels are used in grinding machines.. The wheels are generally made from a composite material consisting of coarse-particle aggregate pressed and bonded together by a cementing matrix (called the bond in grinding wheel terminology) to form a ...
An apparatus useful for sintering unsintered abrasive grain precursor to provide sintered abrasive grain. The sintered abrasive grain can be incorporated into abrasive articles such as bonded abrasives (e.g., grinding wheels), coated abrasives, and nonwoven abrasives.

Sintering parameters and wear performances of vitrified bond diamond grinding wheels Article in International Journal of Refractory Metals and Hard Materials 25(1):25-31 · January 2007 with 154 Reads
In addition, in order to achieve sintering of the grinding wheel, a temperature higher than 1200 °C [2] is usually required to generate a liquid phase, so the high energy consumption is a big drawback of the ceramic binders. The glass binder is regarded as an idea matrix material for grinding wheel.
In addition, compared with synthetic diamond and CBN, ceramic abrasive grain has better versatility, which can be used for not only dry or wet grinding with water or oil cooling, but also for grinding black and non-ferrous metals, and effectively applied to grinding special materials such as stainless steel and heat-resistant alloy.
