used. When using a cutoff tool, lubricant should be sprayed from underneath the cutting tool up into the cut. Spraying on the top side of the tool does not work because the entire cutting edge is covered by the chip being formed. When turning the end of the material or ODs, where the cutting tool is not entirely covered by the material, it is better to spray on the top side of the tool. e spray should be directed so that it hits the cutting edge and some lubricant lands on the material being machined. As the cutting edge moves through lubricant film on the material it will help lubricate the cutting edge. e existing coolant ports on a turning machine are used to route the MQL fluids to the toolholder on the turret. All but one of the ports are blocked off, and a nozzle designated for the specific holder is created. As with any external MQL nozzle, the MQL fluids need to be applied to the cutting tool/workpiece interface, so this approach allows the customization and positioning needed for each tool to be done independently. When the nozzle is not positioned correctly, lubricant often ends up applied to the cut chips, resulting in smoking and prema- ture tool wear because the tools are not getting the neces- sary lubrication. Like all MQL applications, proper steps need to be taken to ensure that the end results are successful. Paying atten- tion to and addressing all critical factors will help ensure the success of any MQL system.

All other open coolant ports should be plugged.
