This article offers an overview of 11 grinding wheel construction modifications used in the peripheral grinding of flat, shaped, internal, and external cylindrical surfaces, when grinding wheels made of superabrasive grains are used (natural and synthetic diamonds, as well as mono-and microcrystalline cubic boron nitride). The text contains characteristics of grinding wheels with: bubble corundum grains, glass-crystalline bond, conic chamfer, zones of different diameters, a centrifugal provision of the coolant into the grinding zone, aggregate grains, zone-diversified structure, as well as impregnated (self-lubricating), multiporous, segment and ''intelligent'' grinding wheels. Each of the presented structural modifications were described by giving construction scheme, used abrasive grains, range of applications, advantages as well as disadvantages. Modifications of the grinding wheel construction allow for effective improvement of both the conditions and the results of the grinding process. A wide range of the known modifications allow for their proper selection depending on the required criteria of effective evaluation and taking into account the specific characteristics of superabrasive grains. As a result, it is possible to obtain positive influence on a number of technological factors of the grinding process. The described modifications of the grinding wheel structure can be also an inspiration and the basis for creating new solutions in this field.

The intense heat generation involved in the grinding process, due to high speci®c energy and high wheel±workpiece friction, is critical to the product quality. Cooling and lubrication therefore play decisive roles in grinding tribology. Conventional liquid coolants employed in¯ood form are ineVective due to the 'air barrier' and '®lm boiling' eVects. Further, grinding¯uids cannot be recommended in the light of ecological and economic manufacture. Minimization or possible elimination of grinding¯uids by substituting their functions by some other means is emerging as a thrust area of research in grinding. The present study explored the possibility of application of solid lubricants in grinding, as a means to reduce the heat generated due to friction, towards ®nding an alternative for the conventional coolants. It covers a feasibility investigation with a variety of solid lubricants and the development of grinding processes or technologies with this concept. Improved process results were obtained with solid lubricant application; if it can be applied in a proper way with means for swarf removal and wheel cleaning, this concept could emerge as an eVective alternative to conventional coolants.
