<p>A gear finishing machine comprising a frame, a tool head on the frame, a work slide movable on the frame toward and away from the tool head, a rotary work gear support on the slide with its axis perpendicular to the direction of slide movement, and means for moving the rotary work gear support in back and forth traverse strokes on the slide in a plane perpendicular to the direction of slide movement. The tool head comprises a fixed mounting member, a pivot support angularly adjustable on the mounting member about an axis parallel to the direction of slide movement. A tool carrier is pivoted to said pivot support for pivotal movement about an axis perpendicular to the direction of slide movement, and has a rotary tool support thereon having an axis of rotation parallel to the pivot axis of said carrier. The pivot axis of the carrier is located laterally from the axis of the rotary tool support. Means are provided for driving one of the rotary supports in rotation.</p> |
