Energy beam director apparatus

摘要

In a laser beam processing of the side surfaces of gear teeth, a rotatable disk is inserted in the recess between the teeth to reflect and redirect laser beam energy toward one surface while protecting the surface of an adjacent gear tooth. The rotatable disk is relatively thin and accordingly is cooled by means of liquid and/or gas jets. During the laser beam operation on the surfaces of the gear teeth, the laser beam, as well as the rotating disk, are translated across the face of the gear tooth.
