Method of mist lubrication, chip vacuum and coil cooling

Abstract

A method of mist lubrication of a drill, suctioning chips cut by the drill, and cooling the coil of an electromagnetic riveter includes aligning the open top of a drill/suction cavity of a movable shuttle body with a drill which descends through the cavity and through a tapered opening at the bottom of the cavity to drill a hole in a workpiece clamped by a pressure foot attached to a carrier in which the shuttle body slides. As the drill descends through the cavity, mist lubrication is blown on the drill bit through a nozzel aligned with a port opening in the side of the cavity. Drill chips cut by the drill bit are suctioned away from the workpiece as they are made through a second port opening in the side of the cavity which is connected to a vacuum hose. Air is blown into the cavity through the same nozzel to swirl the chips as they are being cut by the drill to facilitate their removal through the vacuum port. The coil of an electromagnetic riveter is cooled by conduction to a transducer with which the coil is in contact. The transducer is cooled by unconditioned plant air blown across a set of fins in the sides of the transducer.
