ABSTRACT:
A reciprocating pump for delivering cutting fluid to the machining situs between a tool and a workpiece includes a collapsible piston which forms a substantial seal in the pump during the power stroke and then collapses during the relaxation stroke to allow the piston to reassume its initial position in preparation for the next power stroke. The pump includes an indexer and switch which maintain the pump in an operative condition, thereby delivering cutting fluid to the machining situs for a predetermined amount of displacement between the tool and workpiece prior to engagement and subsequent thereto. The indexer and switch exploit a predetermined amount of play in the switch to maintain the pump in an operative condition for the desired time. The pump also includes a one-way check valve at its inlet port which incorporates a positive pumping action to force a predetermined amount of fluid through the inlet port in the reverse direction, thereby preventing dribbling, siphoning, or a miniscus from forming at the delivery nozzle of the pump. A main feature is to allow precise control of the amount of cutting fluid applied for extremely light to medium machining operations for economy of expensive cutting fluids and for reduction of the hazard to the machine operator from the prior art practice of using an oil mist or a small brush to apply cutting fluid to the rotating cutting tool.
