Friction, cooling and lubrication in grinding

It is generally considered that the heat produced during the grinding process is critical in terms of workpiece quality. Relatively high friction effects in abrasive machining cause heat generation which can lead to thermal damage in the surface layer of a machined part; cooling and lubrication therefore play a decisive role during grinding. The keynote paper shows the effect of coolant type, coolant composition and coolant supply on grinding processes and process results. Further investigations in the fields of fluid dynamic processes in supply nozzles and in the grinding zone are the key to optimization of cooling and lubrication during grinding, thus offering the chance to minimize the amount of coolant in circulation, leading to a reduction of adverse environmental effects and cost.
