In Grinding, Coolant Application Matters

2008-3-1  Several researchers have developed flow rate models based on a 4°C increase in temperature of the coolant exiting the machine over that entering the machine. Others use a fixed flow rate of 25 gpm per inch of grinding width. I use a flow rate based upon the grinding power created during the process, because the more aggressive a cycle is, the ...

Cooling during grinding – grindaix GmbH

To achieve this, coolant lubricant (oil or emulsion) is used which is introduced into the machining zone via nozzles. There, the coolant lubricant cools the process and reduces the friction between the workpiece and tool. coolant lubricant may also perform other tasks within the machine tool (e.g. cleaning the grinding wheel, bed flushing). Due to process cooling, higher cutting speeds and infeeds are possible, and the grinding process is rendered more stable, ideally without grinding

Industrial Coolant Filtration System and Filters For

A CFS for Grinding process is sized based on wheel grit size, viscosity of fluid and material of component. As the viscosity increases or the grit size becomes finer, the flow velocity through filter media has to be reduced to achieve desired results. A CFS for grinding is similar to indivisual filtration system but at a much larger scale.
