“…Nanoparticles are added to CLF because of their high thermal conductivity and advanced tribological characteristics. CLF enriched with nanoparticles is characterized by changed heat conduction properties and different, in comparison with conventional cooling of the grinding zone, by heat exchange, reducing the phenomena of grinding energy dissipation and lowering the workpiece surface temperature [37][38][39].…”

Control of thermal conditions in the grinding zone is possible through effective delivery of substances with cooling, lubricating and antiadhesive properties during the machining process. In addition to the benefits of coolants, however, a number of economic and ecological problems arise, which include the costs of purchase, use and maintenance as well as the environmental impact of its disposal. These negative aspects of the use of cooling and lubricating liquids have contributed to the modern trend of minimizing their output in machining processes, including grinding. This article presents comprehensive characteristics of knowledge in the field of liquids, gases and solids with cooling, lubricating and antiadhesive properties. The author’s original classification of cooling and lubricating agents by their physical state was proposed and a complete list of known modern environmentally friendly methods of cooling and lubrication of the grinding zone was presented. In order to highlight their beneficial features, the background of conventional methods of delivery coolants, lubricants and antiadhesives to the grinding zone used for years were also characterised. A comprehensive list of all known methods of cooling and lubrication of the grinding zone classified according to the physical state of the delivered medium with a clear separation of hybrid methods consisting in simultaneous delivery of many cooling and lubricating agents was described in the summary. The article concludes with the characteristics of directions of further development in the field of cooling and lubrication of the grinding zone.

“…The non-covalent functionalization process of GNP using CTAB was discussed elsewhere. 19 for preparation of nanocutting fluids. When the cutting fluid with GNP inclusions is used in MQL grinding, it is expected that the GNP adhere to the grinding surface and reduces the friction as one graphene sheet slides over the other.…”

The main objective of this work is to assess the performance of graphene nanoplatelets–based cutting fluid in minimum quantity lubrication grinding of Inconel 718. Nanocutting fluids with varying concentrations and different specific surface areas of graphene nanoplatelets were developed, and basic properties like viscosity and thermal conductivity were evaluated at different temperatures. The role of graphene nanoplatelets concentration and specific surface area is investigated by comparing force generated during grinding, surface roughness, grinding temperature, grinding coefficient and specific grinding energy. The experimental results show that graphene nanoplatelets significantly lower the grinding force, temperature, specific grinding energy and roughness of the finished surface. Nanocutting fluid with 0.3 wt% graphene nanoplatelets and 750 mm2/g was found effectively improved the surface quality of the Inconel 718 compared to dry grinding and minimum quantity lubrication grinding with soluble oil.

“…The histogram shows that the minimum values of Espec can be achieved with the simultaneous use of chromium diiodide impregnated grinding wheel and the cooling lubricant, which consists of 5% aqueous solution of emulsion "Ukrinol-14" with the addition of 20 g/l of chromium diiodide. Apparently in this case, chromium diiodide, which is a part of lubricating and cooling technology, not only reduces the coefficient of friction in the area of contact of the abrasive grain with the processed material, but also contributes to the permanent restoration of chromium diiodide in the impregnated wheel [24][25][26][27][28][29][30][31].…”

The article describes a way to increase the efficiency of an abrasive tool by its impregnation in an aqueous solution of chromium diiodide. The device scheme for impregnating the instrument is proposed. Research results of durability of tools impregnated with chromium diiodide and structural condition of material of a surface layer of details after processing are resulted. Within of the researches presented in the article the grinding processing a shafts made from various iron-carbon steels with prepared abrasive tools was conducted. As a result of the machining the scattering fields of the batch sizes of the parts within the grinding wheel resistance were determined. This data for processing with standard grinding wheels and impregnated by chromium diiodide were done. Using data from controlled grinding of workpieces, approximate values of the KΔ coefficient were determined depending on the diameter of the workpiece surface, the required size accuracy of part and the method application of the surfactants. It is shown that regardless of the material being processed, the use of a grinding wheel impregnated with chromium diiodide leads to a reduction in the specific value of the accumulated deformation energy Espec. Taking into account these results it is possible to predict up to twofold reduction of the cost of machining with the abrasive tool of grinding parts, which will reduce the cost of their manufacture by 20-25%. The developed process of impregnating grinding wheels with chromium diiodide can be used without large economic costs in many machine-building company also during repair works.
