A grinding wheel or bonded abrasive is made up of thousands of tiny abrasive particles insert in matric calls as 'bond'. In bonded abrasives, porosity is essential to provide clearance for the chips being produced and to provide cooling, otherwise chips would interfere with the griding process. Hardness Comparison of Abrasive Material

Coding of a grinding wheel consists of six symbols as described below Generally abrasive properties like hardness, toughness and resistance to fracture uniformly abrasives are classified into two principal groups : (a)Natural abrasives, and (b)Artificial abrasives. Natural Abrasives Sand stone (solid quartz) These are relatively soft.

Abrasive machining first and foremost generates high stock removal. Abrasive machining is not considered to be a precision grinding process, but that's not to say it isn't precise. Abrasive machining can take the place of "large-chip" machining processes like milling, planing, broaching, and turning.

Grinding is an abrasive machining process that uses a grinding wheel as the cutting tool. A grinding wheel consists of hard, sharp-edged particles. When the wheel spins, each particle acts like a single-point cutting tool. Grinding wheels are available in a multitude of sizes, diameters, thicknesses, grit sizes and bonds.

An abrasive is a material, often a mineral, that is used to shape or finish a workpiece through rubbing which leads to part of the workpiece being worn away by friction.While finishing a material often means polishing it to gain a smooth, reflective surface, the process can also involve roughening as in satin, matte or beaded finishes. In short, the ceramics which are used to cut, …

Maintaining abrasive sharpness is extremely important when penetrating tough material. Choose the right bond type and grade hardness. If the wheel is too hard, it will not release the grain. Verify that the grinding wheel is paired with the correct dressing tool, and optimize the dressing parameters and frequency.

For this reason, it is used for grinding materials of low grinding resistance like cast iron, brass, and copper. The code for silicon carbide is C. 2. Aluminium oxide. It is reddish-brown in colour. Aluminium oxide abrasive is more suitable for grinding most steels because of its greater toughness to cope with increased grinding resistance offered.
