Machine cutting tool selective lubricator with air blow-off

摘要

A system to selectively lubricate and to continuously supply a forced air flow onto a machine cutting tool has a control valve to selectively communicate an air supply with a pulse generator which drives at least one liquid pump to control the discharge of liquid lubricant from the liquid pump into a continuous forced air flow from the air supply to discharge onto the cutting tool through a nozzle atomized lubricant and cooling air during machining and thereafter only forced air to evaporate and blow off the lubricant from the cutting tool and workpiece, to remove any residual material and chips of the machining operation from the cutting tool and to cool the cutting tool. To minimize the amount of liquid lubricant used by the system and the quantity of used lubricant which must be disposed of, the control valve allows air to flow from the air supply to the pulse generator only during machining when it is necessary to lubricate the cutting tool.
