MQL Unit Enables Precise Control Over Cutting Lubrication
IMTS 2018: Unist’s Quantum minimum quantity lubrication (MQL) unit interfaces with machines to give users detailed control over how much fluid is used.
Unist’s Quantum minimum quantity lubrication (MQL) unit interfaces with machines to give users detailed control over how much fluid is used. The unit is designed to provide reliable, digital control over cutting lubrication. It supports up to six independent outputs and is suitable for use with external spray nozzles and through-spindles.
Users control the unit through discrete signals or its command-based RS-232 interface, which provides a number of MQL rates. At any time, users can specify the exact oil and air to be used.
Minimum quantity lubricant can save money, improve tool life and improve the part finish. But it may involve changes to both the equipment and the processing strategy.
This micro-volume coolant delivery system uses ethanol as the cooling medium for non-ferrous workpieces. The ethanol evaporates after it cools the cutting tool, so no residue is left behind on machined workpieces.
Bacterial growth in metalworking fluids eventually leads to machine downtime. Furthermore, shop owners and plant managers see an increased cost of purchasing replacement fluids and the disposal of spent fluids.
